+# Coil Bypass Overview
+
+This is the first article in a series that explores the idea of a coil bypass strategy in an HVAC system. This article introduces you to a
+coil bypass strategy at a high level, future posts will dive deeper into the features, benefits, as well as the challenges of this style of
+system.
+
+## What is a Coil Bypass
+
+A coil bypass is not to be mistaken for a zoning system bypass, where airflow is "relieved" from the supply side of the system back into the
+return. Instead, a coil bypass diverts a portion of the airflow around the coil using a bypass damper(s). The bypass can serve several
+functions depending on the application, but in general it allows for a constant volume of air to be delivered to the space while the output
+of the coil can be shifted towards more or less dehumidification. In other words, it decouples the total system airflow from the coil
+airflow.
+
+The bypassed air mixes with the supply air stream to act as a reheat source, however unlike a typical reheat source it does not add more
+sensible load to the structure, instead it just brings the supply air temperature closer to the existing home's temperature while still
+covering the latent and sensible loads of the home. A warmer duct system reduces the losses of the duct to unconditioned spaces as well as
+reduces the risk for duct condensation.
+
+The coil bypass strategy, as far as I know, was pioneered by [Harry Boody](https://www.linkedin.com/in/harry-boody-9b8a4366/) of Energy
+Innovations and Scientific Environmental Design, Inc. However their websites are no longer active, so I'm not sure if they are still active
+in the HVAC design space or not.
+
+## The Problem
+
+| Why      |                                                                  |
+| -------- | ---------------------------------------------------------------- |
+| Question | Why would we want to utilize a strategy such as the coil bypass? |
+| Answer   | Improved indoor air quality (IAQ)                                |
+
+ASHRAE's recommandation for the amount of air changes per hour (ACH) in a residential structure to be in the range of 3-5 ACH, and in
+general the higher the better, along with a MERV 13+ filter. In some / most cases the system airflow does not meet that criteria, especially
+low load homes or high volume homes.
+
+For example, let's imagine a single story ranch home that is 2,500 square feet with 9 foot ceilings. This home is relatively tight
+construction and after doing the heating and cooling loads we've selected a 2.5 Ton system for this home. It is located in a green grass
+climate that needs some priority on dehumidification and requires an airflow of 350 CFM/Ton (875 CFM).
+
+We determine the volume of the conditioned space.
+
+2,500 x 9 = 22,500 ft^3
+
+![volume-equation](/articles/images/2023-08-10-volume-equation.png)
+
+| **Where:** |                                       |
+| ---------- | ------------------------------------- |
+| **V**      | _is the volume of the home_           |
+| **ACH**    | _is the desired air changes per hour_ |
+| **60**     | _conversion from hours to minutes_    |
+
+Below is a table of the required CFM to meet the different air changes per hour.
+
+|                 |         CFM         |
+| --------------- | :-----------------: |
+| (22,500 x 3)/60 | **_1,125 @ 3 ACH_** |
+| (22,500 x 4)/60 | **_1,500 @ 4 ACH_** |
+| (22,500 x 5)/60 | **_1,875 @ 5 ACH_** |
+
+As you can see we have a discrepency of meeting even the low end of 3 ACH. The high end of 5 ACH is over 2x the airflow for our 2.5 Ton
+system. The coil bypass strategy is one viable way, by decoupling the total system airflow from the coil airflow without, which eliminates
+the need of an auxilary fan / system that circulates air through some sort of filtration system.
+
+### Multi-Stage Systems
+
+A challenge with multi-stage systems, even when sized properly, is that we often run at part-load conditions, and spend the majority of the
+time in lower stages. The lower stages often do worse at dehumidification than when running at full load.
+
+When the equipment runs in lower stages on a traditional system the total system airflow is reduced even further from the recommended air
+changes per hour. This reduced airflow also causes the throw of the air from the registers to be reduced which can lead to increased odds of
+stratification, poor air mixing, and increased potential for poor mean radiant temperatures (MRT) of the surfaces. The decreased airflow in
+low stages, lowers the velocity in the duct system, while low velocity is not a concern, it does increase the duct gains and increase the
+possibility of condensation on the ducts when they're located outside of the thermal envelope of the building.
+
+Let's imagine we have a duct system that has high wall registers located in a soffit at the interior wall that moves 100 CFM and we are
+trying to throw the air to the exterior wall which includes a window. The wall is @ 12 feet from the register. We've selected a register
+that meets the criteria, at high stage airflow it has a throw of 11.5 feet (shown as the green rectangle). When the system runs in low
+stage, the airflow is reduced to 70% of high stage (70 CFM), which would give us a throw from the register of @ 7 feet (shown as the red
+rectangle).
+
+![register-throw](/articles/images/2023-08-10-register-throw.png)
+
+The reduced flow through the register causes the air to only make it about 60% across the room before reaching it's terminal velocity, which
+can cause the room to feel uncomfortable since the air never reaches the exterior wall and window.
+
+By decoupling the fan from the coil airflow it is possible to run in low stages, still have adequate dehumidification performance out of the
+system, and achieve the proper throw from the registers.
+
+## Conclusion
+
+In this article we've begun to scratch the surface of what a coil bypass strategy is in an HVAC system, as well as some of the challenges
+that it can help solve. We've learned about why we may desire to decouple the total system airflow from the coil airflow.
+
+In future articles we will continue to explore some of the features, benefits, and challenges presented by such a strategy.

+# Pounds of Water Removed
+
+This is an article that shows how to calculate the pounds of water removed from an air stream, given the entering conditions (return air
+stream) and the outlet conditions (supply air stream).
+
+This is useful in the field when you want to calculate the amount of moisture removed from an air-conditioner or a dehumidifier. This
+article assumes that you have knowledge of a psychrometric chart. If you do not have basic knowledge of the psychrometric chart, then here
+are a couple articles to familiarize yourself.
+
+## Articles
+

+- [Impact of Adding or Removing Water from Air](https://hvacrschool.com/the-impact-of-adding-or-removing-water-from-air/)
+
+## Scenario
+
+Let's imagine that we have an air-conditioner that has the following measurements taken:
+
+- Return Air: 75° / 50% RH
+- Supply Air: 55° / 81% RH
+
+We plot the two values on the psychrometric chart (black line represents the return air conditions and blue line represents the supply air
+conditions).
+
+![chart](/articles/images/2023-09-08-pounds-of-water-removed.png)
+
+We start by finding the corresponding dry-bulb temperature at the bottom of the chart and draw a straight line up to where it intersects the
+relative humidity curve. After that we draw a straight line to the right side of the psychrometric chart to find the grains of moisture per
+pound of air.
+
+This gives us the following values:
+
+- Return Air: 66 gr/lb
+- Supply Air: 52 gr/lb
+
+We can then use the following formula to calculate the pounds of water removed.
+
+![formula](/articles/images/2023-09-08-formula.png)
+
+| **Where**    |                                                          |
+| ------------ | -------------------------------------------------------- |
+| **W**        | _Weight of water in pounds per hour_                     |
+| **4.5**      | _Constant based on density / specific heat of moist air_ |
+| **CFM**      | _Airflow in cubic feet per minute_                       |
+| **∆G** | _Difference in grains of moisture_                       |
+| **7000**     | _Constant based on grains of moisture in saturated air_  |
+
+## Solution
+
+First, we solve for the difference in grains between the two air streams.
+
+∆G = 66 - 52 = 14
+
+Next, we've measured our airflow and have determined to have **797 CFM** of airflow across the evaporator coil, so we can substitute our
+values into the formula.
+
+![solution](/articles/images/2023-09-08-solution.png)
+
+So, we are removing about 7 pounds of water per hour at these conditions.
+
+Another thing to note is that 1 pound of water is approximately 1 pint of water, which can be useful when working with dehumidifiers that
+can often be rated in pints per day.
+
+I hope you've found this article helpful, thanks for reading!

+
+# Why Mini Splits Stink
+
+In this general article, I explain why I don't generally like to use mini-splits.
+
+## The Positive Sides
+
+When people say mini-splits, in general we mean "ductless" style units. These can either be high wall, floor mounted, or ceiling mounted
+consoles. These units do offer really high efficiency and becuase they're "ductless" you don't have duct gains/losses.
+
+These units are common in many other countries and have been around for a long time. They do are generally quick and fairly easy to install,
+but are mostly a pain in the tail to work on.
+
+So, the plus side to these units are that they are really efficient, they generally have models that have a high-heat output for colder
+climates, although this option is becoming more prevelant in traditional unitary style heat pumps as well. You do not have heat gains or
+losses due to ductwork being in unconditioned spaces.
+
+## The Down Sides
+
+Most mini-split systems do not do the greatest at humidity removal. This is partially because they use proprietary algorithms to control the
+blower and compressor. They do achieve long run-times, which is often good for comfort stand points, however there is generally not a good
+way to control / hack them to work towards achieving good IAQ.
+
+These units offer next to no filtration, so in order to have filtration you need to utilize a stand-alone / portable filtration means. Which
+a lot of the portable filtration systems have problems of their own (come bundled with UV / PCO technology or other "space" technology that
+can lead to their own IAQ problems). It also introduces another fan, which may / may not be that efficient. In other words, when considering
+other items to make them more comparable to what a traditional system offers, are they really that much more efficient?
+
+These systems also do not have a good method of offering basic fresh air control / management, so other systems, such as an ERV need to be
+installed to handle the fresh air requirements of the building.
+
+The controls for these systems are often hard to understand / use. They do allow you to change fan speeds, but they control the compressor.
+The fans often run all the time, which is not necessarily a bad thing, but they don't really offer many ramping profiles or adjustments to
+change the blower speed when the compressor is off vs. on.
+
+These systems get dirty quickly, are generally a pain to clean properly, and are not easily repairable. Manufacturer support is often poor,
+the documents aren't always translated very well, and most technicians hate to work on them.
+
+# What about ducted models?
+
+But what about the ducted models? Well, the ducted models are a step in the right direction. You can use filters on them, although some of
+the manufacturer's do not recommend installing better / improved filter cabinets (like a 4-5" media filter), however we have done that
+successfully many times and always include media filters as an option on our installations, but you do need to make sure that they have a
+very low pressure drop, as they a lot are not designed for very much static pressure.
+
+The ducted models still generally have the same control problems, previously mentioned. If you read my introduction to the
+[coil-bypass-system](https://mhoush.com/posts/coil-bypass-overview/), you have a basic understanding that even most traditional systems /
+designers do not focus on the proper air-changes in a structure to maintain proper IAQ levels.
+
+You can't easily pair mini-splits with larger fan-coils because they are "communicating" style systems.
+
+## Conclusion
+
+Don't get me wrong, there are applications that are well suited for mini-splits. These are often applications like sun-rooms, garages, small
+server-rooms / network storage rooms, and many others. But in my opinion these are not at all my favorite and are generally really far down
+my list of options that I want to recommend to my clients.
+
+As an industry, I feel we need to step back and refocus on the pillars of IAQ. Filtration, fresh-air, and humidity control. The
+manufacturers / government should put less emphasis on chasing efficiency just to shoot ourselves in the foot and loose the qualities that
+make traditional / unitary style systems cover more if not all of the 3 pillars of proper IAQ.
+
+There's plenty that I did not cover and I'm sure I missed some things, but just needed to rant for a few minutes... Thank you for making it
+to the end!

+# Dehumidifier Sizing by Latent Load
+
+This is a quick article to show how to calculate the size of dehumidifier needed based on the latent load of a building. This is useful if
+you've done a load calculation and know the latent load of the structure.
+
+## Formulas
+
+The formula above is used to solve for the pints per hour required to size a dehumidifier.
+
+| Where |              |
+| ----- | ------------ |
+| Ql    | Latent load  |
+| Ph    | Pints / hour |
+
+We can then convert to pints per day by multiplying the answer by 24 hours, below is the combined formula.
+
+![pints-per-day-formula](/articles/images/2023-09-15-pints-per-day.png)
+
+| Where |             |
+| ----- | ----------- |
+| Ql    | Latent load |
+| Pd    | Pints / day |
+
+In some cases you may want to size the dehumidifier for less than the full latent load, assuming that the air-conditioner (when sized
+properly) is going to cover the full latent load when at peak design temperatures and that the peak latent period for your area is during
+peak cooling demand.
+
+## Example
+
+Let's imagine we have done a load calculation and have a latent load of 4,334 BTU/h. So, plugging that into our above formula.
+
+![pints-per-day-formula-example](/articles/images/2023-09-15-pints-per-day-example.png)
+
+Or if we just want to cover the latent capacity at 85% of the full latent load.
+
+![pints-per-day-formula-example](/articles/images/2023-09-15-pints-per-day-example2.png)
+
+This gives us some guidance that we would need to select a dehumidifier that is rated for 84-99 pints per day, depending on which condition
+we wanted to use.
+
+I don't feel oversizing a dehumidifier, within reason, is that problematic (or at least it does not come with the same problems as an
+oversized air conditioner), so I would personally go for a 100-120 pint per day model dehumidifier in this application.
+
+Thanks for reading!

+# Introducing Psychrometrics CLI
+
+Today, I'm releasing a command line application that is built on top of my
+[swift-psychrometrics](https://github.com/swift-psychrometrics/swift-psychrometrics) package, that I open sourced over 2 years ago.
+
+The application consists of many calculations / conversions for psychrometric properties of an air stream. The tool works for both imperial
+and metric units. The application will work natively on macOS, but can also be ran through a `docker` container on other platforms.
+
+## Why
+
+I spend a lot of time in my terminal, because I can work so much more efficiently. I discovered many years ago that the more I can do using
+simple applications and keyboard over a mouse and a web browser or native application the more I can accomplish. I understand this is
+intimidating for many who think they are _"not good with computers"._ I can assure that was me several years ago, I would only encourage you
+to not be afraid and give it a shot. We are at a time in society where it is easier than ever to get informed and learned new skills.
+
+## Installation
+
+For complete installation instructions, you can view the [github](https://github.com/swift-psychrometrics/psychrometrics-cli) repository.
+
+The following instructions are based on using macOS.
+
+### Open your terminal application.
+
+Personally, I use [iTerm2](https://iterm2.com/), however you can use the default `Terminal` app. Found at
+`/Applications/Utilities/Terminal.app`.
+
+## Install Homebrew

+We use [Homebrew](https://brew.sh) for package distribution of the pre-built application binaries. You can follow their instructions to
+install.
+
+### Tap our custom formula tap.
+
+```bash
+brew tap swift-psychrometrics/formula
+```
+
+### Install the psychrometrics application
+
+```bash
+brew install psychrometrics
+```
+
+That's it!
+
+## Usage
+
+I will run through a couple of the commands that are supplied with the application and show what you can expect the outputs to be.
+
+### Properties
+
+The following command will output a bunch of the psychrometric properties of an air stream. There are several ways to call it, but generally
+you will supply the dry bulb temperature and the relative humidity.
+
+Below, we calculate the psychrometric properties based on 75°F and 50% humidity.
+
+```bash
+psychrometrics --dry-bulb 75 --relative-humidity 50
+```
+
+![properties-output](/articles/images/2023-09-18-properties.png)
+
+### Dehumidifier Sizing
+
+If you've read some of my recent articles on calculating the
+[dehumidifier size required based on the latent load](https://mhoush.com/posts/sizing-dehumidifier-by-latent-load/), the application also
+ships with a calculation that will do this for you and has the ability to calculate it at different `coverages` that you can supply.
+
+For example if we've done a load calculation and determined that we have a latent load of `4,334 BTU/h` then we could run the following
+command to see what size dehumidifier is needed for `100%, 85%, and 70%` of the latent load.
+
+```bash
+psychrometrics dh size --coverage 100 85 70 --verbose 4334
+```
+
+![dh-size](/articles/images/2023-09-18-dh-size.png)
+
+### Pounds of Water Removed
+
+I also recently wrote an article about [calculating the pounds of water removed](https://mhoush.com/posts/pounds-of-water-removed/) from an
+air stream given the grains of moisture removed.
+
+Below is an example of calculating the pounds of water removed per hour based on the example in the article (14 delta-grains)
+
+```bash
+psychrometrics dh pounds-removed --delta 14 --cfm 797 --verbose
+```
+
+![pounds-removed](/articles/images/2023-09-18-pounds-removed.png)
+
+### Help
+
+You can use `--help` option to show help and the list of commands provided.
+
+![help](/articles/images/2023-09-18-help.png)
+
+If you have any questions then feel free to email or message me. I hope some of you may find this application useful.

+# Introduction to Programming for HVAC Part-1
+
+This is part one of a series of articles to help HVAC technicians (or others) get started in developing their skills to program. This can
+help to automate everyday tasks or just familiarize themselves with some of the tools used by programmers.
+
+## Why
+
+I think if nothing else, this series can help gain knowledge, tips, and tricks to make you more comfortable with your computer. I hope that
+you will at least learn how to use your `terminal` application and more specifically `vim` motions and keybindings (more on that in another
+article).
+
+The goal of this article is to just get a machine setup with tools and to start exploring. I am a shill for `macOS`, so all of these will be
+specifically geared towards that and my workflows, most everything that is showcased should also work on `linux` machines (not sure about
+`windows`), although you may have to search for specific instructions on installing software for other platforms.
+
+What I have learned on my journey in programming is that the more you can lean on small software packages that focus on a single task, but
+do them well, the better. The less you use your mouse, the more productive you can be. The more you can work with `text` files and formats
+the more portable and transformable your workflows can be.
+
+## Getting Started
+
+The first thing that we will focus on is becoming familiar with the terminal application. On macOS the terminal application is located at
+`/Applications/Utilities/Terminal.app`. However, rather than click around to find it, you can use the `⌘<space>` to pull up your spotlight
+search, then type `Terminal` to select the terminal application.
+
+![spotlight](/articles/images/2023-09-21-spotlight.png)
+
+### Terminal Overview
+
+Your terminal is a program that allows you to run programs by typing commands into it's window. There are a lot of built-in commands and a
+bunch that you can install. The terminal is very customizable (and once familiar, you will constantly be tweaking / adjusting to suit your
+needs). Right now customization is not what we will focus on, however in future articles I will provide tips and tricks on customizing it.
+Right now, we only need to know how to open it up and type in commands.
+
+![terminal](/articles/images/2023-09-21-terminal.png)
+
+Below is an image / explanation of what the default status line includes.
+
+![terminal-line](/articles/images/2023-09-21-terminal-line.png)
+
+### Learn Basic Commands (Built-in)
+
+Here are a few basic commands that you should familiarize yourself with, as you will use them often when working inside of a terminal.
+
+### Change Directory
+
+`cd` (change directory) is the command that allows you to move around your file system when inside the terminal.
+
+> **Note:** `~` is a representation of your `Home` directory.
+
+```bash
+cd ~/Documents
+```
+
+The above command will move you into your Documents directory.
+
+> **Note:** If there are spaces in the name of the directory you try to move to then the easiest way is to wrap the name in quotes.
+
+```bash
+cd "~/Documents/Product Concepts"
+```
+
+Some other things to understand when moving around / supplying arguments to the `cd` command.
+
+You can use `..` to go backwards / move up to the parent directory. For example, say we are in the `~/Documents` directory, to go back up to
+the home directory we could use the following:
+
+```bash
+cd ..
+```
+
+These can be chained together as well. For example say we are located in the `~/Documents/Product Concepts` directory, we could use the
+following to go up two directory levels back to the home directory.
+
+```bash
+cd ../..
+```
+
+> **Pro-Tip:** You can use the `<tab>` key when navigating to auto-complete, generally typing a few characters followed with the `<tab>` key
+> will auto-complete for you.
+
+### List files
+
+Use `ls` to output a list of files and directories where you are located.
+
+```bash
+ls
+```
+
+_Example Output when in my ~/Documents directory_
+
+```bash
+Estimates.app
+InkscapeDrawings
+KwikModel
+MyAparment
+NCISummit
+Personal
+Product Concepts
+Receipts.receipts
+RingCentral
+SketchUP
+Tech-Tips
+desktop.ini
+espanso-migrate-backup
+espanso-migrate-backup-2
+```
+
+Using options with `ls` to show more statistics and hidden files. There are often hidden files on your computer that are used for
+application support or other purposes, these files are not shown using the default command. Hidden files start with a `.`, below is an
+example of showing hidden files in your home directory.
+
+```bash
+ls -la ~/
+```
+
+> **Note:** Above I added the `~/` which will allow you to list the files in your home directory even if you currently are not there in your
+> terminal, if you were already there (for example by using `cd ~/` then you would not need to use that at the end of the command.
+
+_Example Output_

+```
+
+As you can see, I have a lot of hidden files and folders, your output will probably look much different than mine.
+
+### Clearing the Terminal
+
+Often times you may want to clear the terminal screen. You can use the `clear` command to clear the screen of the terminal.
+
+```bash
+clear
+```
+
+Or use a keyboard shortcut `⌃l` (`<control>l`)
+
+### Creating Directories
+
+Use `mkdir` (make directory) to create a directory.
+
+First, let's move into the `tmp` directory, the `tmp` directory is a directory on your file system that is typically used for applications
+to write temporary logs / files to, it get's erased everytime your computer is restarted. We can use the `cd` command that we learned
+earlier.
+
+```bash
+cd /tmp
+```
+
+Next, let's create a new directory called "MyDirectory".
+
+```bash
+mkdir MyDirectory
+```
+
+#### Gotcha's with 'mkdir'
+
+By default you can't create directories that are multiple levels deep, unless the directories already existed or we provide the `-p` option.
+For example, if we want to create a directory at `/tmp/MyOtherDirectory/Nested/Deeply` then we could use the following command when inside
+the `tmp` directory.
+
+```bash
+mkdir -p MyOtherDirectory/Nested/Deeply
+```
+
+Now, try out using the `<tab>` key with the `cd` command to navigate to the `Deeply` folder.
+
+```bash
+cd MyOther <tab> <tab> <tab>
+```
+
+### Open Command
+
+You can use the open command to open files or folders in the default application for the file type.
+
+For example, if we want to open a `Finder` window while in the `/tmp` directory, we can use the following command:
+
+```bash
+open .
+```
+
+### Manual Pages
+
+Lastly, to learn more about commands you can use the `man <command>`. To bring up the manual pages for the command in the terminal. You can
+use the arrow keys to navigate around the manual pages and type the letter `q` to quit / close the manual pages.
+
+```bash
+man ls
+```
+
+That is it for the first installment in this series. I hope you learned something and have better understanding of using your terminal.

+# Introduction to Programming for HVAC Part-2
+
+In this article, learn about installing a package manager. If you missed it, check out the
+[first](https://mhoush.com/posts/introduction-to-programming-for-hvac-1/) article in the series where we learned about using your terminal.
+This article builds upon that foundation.
+
+## What is a Package Manager
+
+A package manager is a piece of software that helps to install software and manage updates for your system. For me, the first thing that I
+do with a new machine is install `Homebrew`. [Homebrew](https://brew.sh) is my preferred package manager for `macOS`.
+
+## Why
+
+A package manager is nice because often software relies / requires other dependencies in order to work properly. By using a package manager
+it will make sure that the correct dependencies are installed for the software that you need to run. It allows you to be able to update and
+manage software through a centralized interface.
+
+## Installation
+
+Installation is simple. Open up your terminal and enter the following command (easiest to just copy / paste from the homepage linked above).
+
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+
+This will prompt you for your password in order to create some directories and install the required software for `brew` to work. The
+installation may take some time, while it downloads the command line tools for `Xcode`.
+
+When completed, follow the `Next Steps` and copy / paste the command listed, that should look like below.
+
+```bash
+(echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/<you>/.zprofile
+eval "$(/opt/homebrew/bin/brew shellenv)"
+```
+
+![brew-output](/articles/images/2023-09-22-brew-output.png)
+
+The first line of this command sets up some things in your shell profile (which we have not discussed yet) that will make `Homebrew`
+available to you anytime you start a new session in your terminal. The second line of the command makes it available in your current
+terminal session.
+
+Next run the following command and make sure that everything is setup correctly.
+
+```bash
+brew doctor
+```
+
+Which should output the following:
+
+```
+Your system is ready to brew.
+```
+
+### Terminology
+
+Homebrew calls command line applications `formula` and normal graphical applications `casks`. It has the ability to install both styles of
+applications.
+
+## Search Command
+
+The following command is used to search for software packages:
+
+```bash
+brew search chrome
+```
+
+## Open a Homepage
+
+The following command can be used to view the homepage of a formula or cask in your browser:
+
+```bash
+brew home google-chrome
+```
+
+## Update Homebrew
+
+The following command is used to update homebrew:
+
+```bash
+brew update
+```
+
+## Update packages installed on your system
+
+The following command is used to update software that is installed / managed by homebrew.
+
+```bash
+brew upgrade
+```
+
+You can combine the update and upgrade commands, which will update homebrew and upgrade all the software it manages on you machine with the
+following command.
+
+```bash
+brew update && brew upgrade
+```
+
+## Conclusion
+
+That is it for this article. I will say that for me, when I find a piece of software that I want to use, I generally try to search for it in
+`brew` first, before installing it via other means.
+
+I hope you've found this article helpful. In the next article we will start to use the skills that we've learned in these first two articles
+and write our first program / script.

+# Introduction to Programming for HVAC Part-3
+
+In this article we will put together some of the pieces from the last 2 articles, and build our first program. If you have missed the first
+articles, then you can catch up [here](https://mhoush.com/series/programming-for-hvac/) before continuing with this article.
+
+## Getting Started
+
+We are going to make our first script / program. This first program is really just setting up some building blocks for our next program we
+will write, that will remove the background from an image.
+
+### Creating a scripts directory
+
+We learned in the [first article](https://mhoush.com/posts/introduction-to-programming-for-hvac-1/) how to use our terminal. Today we are
+going to use some of the commands we learned to create a directory where we can store our script and future scripts that we write.
+
+**Create a directory**
+
+```bash
+mkdir -p ~/.local/bin
+```
+
+The above command will create a "hidden" directory in your home folder. We can go ahead and move into the directory we just created.
+
+> **Note:** The `-p` option allows us to create nested directories if the parent directory doesn't exist.
+
+```bash
+cd ~/.local/bin
+```
+
+### Hello World
+
+It is common in programming to start out with a "Hello World" program when learning a new scripting paradigm. So let's jump in and get
+started.
+
+**Creating our script file:**
+
+```bash
+touch hello-world.sh
+```
+
+**Now open the file:**
+
+```bash
+open hello-world.sh
+```
+
+The above command should open the file in the `TextEdit` application. In order to make the text edit application to not auto-capitalize
+words and play more nicely, we need to adjust some settings. Open the settings by pressing `⌘,`.
+
+In the **Format** section, select _Plain text_ and in the **Options** section de-select _Check spelling as you type_.
+
+![text-settings](/articles/images/2023-09-24-text-settings.png)
+
+At this point for changes to take place, you will need to close the file and re-open.
+
+> **Tip:** In your terminal you can run the last command in your history by using the `↑` (Up) arrow key.
+
+Now that the file is open again, we will write our hello-world program. The contents of your file should look like the following:
+
+```bash
+#!/bin/sh
+
+echo 'Hello World!'
+```
+
+The first line is referred to as the `shebang`, this tells your computer which shell interperter to run your file. I have not explained the
+shell yet, but it currently would just muddy the waters a bit, but there are several shell interperters on your computer with the `sh` posix
+shell being one of the most universal / lowest level ones, which is why I'm choosing this one (in other words this script would work on just
+about any machine you were on).
+
+The second line we are using the built-in `echo` command and passing it the 'Hello World!' argument.
+
+Now save and close the file `⌘s` (to save) `⌘q` (to quit the text edit application).
+
+**Run the program from your terminal:**
+
+```bash
+/bin/sh hello-world.sh
+```
+
+You should see that `Hello World!` was printed to your console.
+
+![hello-output](/articles/images/2023-09-24-hello-output.png)
+
+### Make Executable
+
+Now that we have our basic script working, let's make it an executable.
+
+**In your terminal, type the following:**
+
+```bash
+chmod u+x hello-world.sh
+```
+
+This will change the mode of the file type to be an executable.
+
+Now move / rename the file so we don't have to call it using `.sh` extension:
+
+```bash
+mv hello-world.sh hello-world
+```
+
+Now that the file is executable, we can execute it by just calling the name of the file.
+
+```bash
+./hello-world
+```
+
+> **Note:** We have to prefix the file name with `./` in the above command so that it knows where to find our file. The `./` is saying run
+> this file in our current directory. In the future we will setup our shell so that it knows to look in our `~/.local/bin` directory for
+> scripts, so that we can call them without this prefix.
+
+## Conclusion
+
+Congratulations, in this article we wrote our first program. We learned how to edit the file, set it's permissions, and execute the program
+from our terminal. I should mention that the `TextEdit` application is generally not how you would program, people typically use what is
+known as an `IDE (integrated development environment)`, however I chose to use the `TextEdit` application because it is built-in to `macOS`
+and allowed us to accomplish our goal without downloading other software.
+
+In our upcoming articles, we will write a program that I hope is useful to you / something that you can build upon and use for a long time.
+Thank you for reading to this point.

+# Introduction to Programming for HVAC Part-4
+
+This article builds upon our [last](https://mhoush.com/posts/introduction-to-programming-for-hvac-3/) article, so make sure to catch up
+before continuing with this article.
+
+## Arguments
+
+Before we start creating our program that will remove the background from images let's go over arguments in shell scripts. Arguments are
+supplied to shell scripts are separated by a space `" "`, as opposed to options which start with a `-<character>` or `--<word>`.
+
+To illustrate this, let's change our `hello-world` script we wrote in the last article.
+
+**Move into our scripts directory:**
+
+```bash
+cd ~/.local/bin
+```
+
+**Make a copy of the hello-world script:**
+
+```bash
+cp hello-world greet
+```
+
+Above we make a copy of the hello-world file and name the copy `greet`.
+
+**Open the greet file:**
+
+```bash
+open -a TextEdit greet
+```
+
+> **Note:** Because the greet file is an executable, in order to open it in the `TextEdit` application we must supply the `-a` option.
+> Otherwise it will just run our `greet` program in another terminal. Use `man open` to read more about the open command.
+
+**Edit the greet file:**
+
+```bash
+#!/bin/sh
+
+echo "Hello, ${1}!"
+```
+
+Make sure to save `⌘s` the file.
+
+Take note that the quotes need to be changed to `"` (double quotes) from our original `hello-world` program.
+
+The `${1}` is indicating that we will insert / interpret the first argument passed to our program and insert it at that location. Arguments
+are interpreted in order they are passed in with `${0}` always representing the filename of the program that is called (generally not needed
+/ used in your scripts).
+
+**Test it out:**
+
+```bash
+./greet Michael
+```
+
+![greet-output](/articles/images/2023-09-26-greet-output.png)
+
+If you'd like to supply multiple words (or arguments that contain spaces) as a single argument then you can wrap them in quotes.
+
+```bash
+./greet "Michael Housh"
+```
+
+> **Tip:** Wrapping in quotes is especially useful for commands that take file paths, if any of the folders or file names contain spaces.
+
+## More Useful Program
+
+At this point, it's time to build a more useful program that we can use. First, we must download some dependencies for our program.
+
+**Install imagemagick:**
+
+```bash
+brew install imagemagick
+```
+
+> **Note:** If you'd like to check out the documentation / website for imagemagick you can run `brew home imagemagick`.
+
+This will take a bit for brew to install imagemagick and it's dependencies. When it's completed, we can check to make sure that imagemagick
+is installed by running the following command.
+
+```bash
+magick --version
+```
+
+It should output something along the lines of this below.
+
+```bash

+Copyright: (C) 1999 ImageMagick Studio LLC

+
+> **Tip:** Don't forget, you can use the `clear` command to clear the terminal.
+
+**Create our script:**
+
+```bash
+touch mktrans
+```
+
+We are going to name our script `mktrans` as a short for make transparent.
+
+**Open the file:**
+
+```bash
+open mktrans
+```
+
+**The program:**
+
+```bash
+#!/bin/bash
+
+# The input file path, passed in as the first argument.
+inputfile="${1}"
+
+# The color to make transparent, optionally passed in as the second argument.
+# by default we handle / make white backgrounds transparent.
+color="${2:-white}"
+
+# Use the built-in basename command to normalize the input file name
+# this will convert a file path, such as ~/Pictures/my-image.png to my-image.png.
+fullfilename=$(basename -- "$inputfile")
+
+# Use the text of the `fullfilename` up to the first '.' as the file name.
+filename="${fullfilename%%.*}"
+
+# Use the text after the last '.' as the file extension.
+extension="${fullfilename##*.}"
+
+# Create the output file name to use.
+#
+# For an input file of `input.png`, our output name would be
+# `input-transparent.png`.
+#
+# This will output the file in the directory that we are
+# in when we use our script (which may different than where
+# the image is located)
+outputfile="${filename}-transparent.${extension}"
+
+# Make the magick happen :)
+convert "${inputfile}" -fuzz 10% -transparent "${color}" "${outputfile}"
+
+```
+
+I've included comments in the program above, which is good practice, as there is high odds that you will forget what is going on when / if
+you open the file up in the future to look at it. We are using a lot of what is called parameter expansion magic in this file. You can read
+up more on what we are doing in the [bash documentation](https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html).
+
+This script is far from perfect, there are a lot of things to be improved upon. For example, if you download / save the banner image of this
+post and run this script, it will also remove some color in the wizards beard, eyes, and eye brows. However, it does work very well for my
+general use case, which is to remove the background from screenshots of pdf documents. It should be noted that it will not work on all types
+of images, some image types do not allow transparency, so it is safest to call this with input image being a `.png` image type, however you
+can use the `imagemagick` program that we downloaded to convert other image types to `.png`, but that will be left up to you to figure out.
+
+## Using Our Program
+
+This is going to assume that you have download the banner image at the top of this article. You can do this by right-clicking and choosing
+`Save As`. This should save the image in your downloads folder, and you can keep the name of `part4-banner.png`.
+
+**Make the program executable:**
+
+```bash
+chmod u+x mktrans
+```
+
+**Make the image background transparent:**
+
+```bash
+./mktrans ~/Downloads/part4-banner.png
+```
+
+**Open the image:**
+
+```bash
+open part4-banner-transparent.png
+```
+
+It should look like below.

+

+
+That is it for this article. In the upcoming articles we will setup our `shell` environment so that we can use the commands we've built
+without having to navigate to the `~/.local/bin` directory. Thank you for reading to the end, I hope you're finding this series helpful.

+# Free quotes != good
+
+I found myself re-reading the
+[ACCA Quality Installation Standard](https://www.acca.org/communities/community-home/librarydocuments/viewdocument?DocumentKey=b1d2a39d-fda8-4af9-b8de-0ae579bfe24a)
+recently and it got me thinking about the industries tendency of offering free quotes. In this article, I'd like to just focus in on the
+items that are required as what I'm calling "prior to installation" items.
+
+## Prior to installation
+
+1. Ensure ventilation calculations are performed.
+1. Building heat gain / loss calculation (Manual-J / Manual-N)
+   1. Room x room for new construction or duct modifications.
+   1. Block load for existing (can use original if available).
+1. Proper equipment capacity selection (Manual-S / Manual-CS)
+1. Properly matched systems (AHRI or CEE-AHRI)
+
+Let's break the above items down to a rough estimated time to complete each of the items.
+
+| Item                                | Time (minutes) |
+| ----------------------------------- | -------------- |
+| Ventilation calculations            | 15             |
+| Manual-J (data gathering)           | 30             |
+| Manual-J (data entry / calculation) | 30             |
+| Manual-S                            | 15             |
+| AHRI                                | 15             |
+| **Total**                           | 105            |
+
+> _The above items are obviously just estimations and the person's experience in the different areas / tools they use. Some of the items are
+> probably on the low side while others are probably on the high side._
+
+This is 1.75 hours just to do the calculations required to meet the QI Standard. This does not include any of the time spent with the
+customer building value in you or your product recommendations.
+
+When you want to not guess at some of the calculations then a blower door test is generally required in order to understand the leakage of
+the home, which adds even more time to the estimation process. Depending on the understanding you are looking for, the blower door test can
+add 30-180 minutes. This takes the total time to 2.25-4.75 hours.
+
+## Pushing boxes
+
+The majority of residential HVAC companies make the bulk of their income off of equipment sales, so they have to "feed the beast" by
+skipping steps in both the installation of equipment and the sales process in order to close jobs and keep the ship afloat.
+
+![sinking-boat](/articles/images/2023-10-04-sinking-boat.png)
+
+This has helped contribute to these industry statistics:[^1]
+
+- **Incorrect refrigerant charge in greater than 50-80% of systems.**
+- **Improper airflow:**
+  - **70% above the rated 0.5" w.c.**
+  - **47% above 0.7" w.c.**
+  - **85% undersized / inappropriate filter.**
+- **70-80% of systems have at least one fault.**
+- **90-100% if duct leakage is considered.**
+
+## Consumer responsibility
+
+Let me be clear, I don't think that all the blame is on the industry here. The culture today is that everyone wants things for free and
+fast. They have been conditioned by online services and box stores. Should we not cater to those that aren't willing to do their leg work?
+Is it really our fault, if they don't care?
+
+## Liability
+
+While it's generally easy to shrug our shoulders and think that it's ok to just continue on because all the competitors are doing the same
+thing. There is at least the possibility that skipping steps can come back to bite you. If things ever went to litigation and the steps
+outlined in the QI Standard are ignored, then there is high odds you would loose.
+
+No matter what you do to try and protect yourself (having customers sign-off, etc) does not adequately protect your company from litigation.
+There are stories out there where contractors were still held liable for not performing load calculations even though the consumer signed
+off on it, because it is not inline with "industry best practices."
+
+# Summary
+
+This has led me to the conclusion that free quotes are just bad for the industry in general. The path forward is a challenge (changing
+perception is hard). I don't know that I have answers on what the best path forward is, to be frank, but I do know that our current _status
+quo_ is subpar to say the least.
+
+Unfortunately, I don't think the change is going to come from the industry, but that it's going to require the consumer base to be more
+educated and demand more from the industry. There have been many organizations that have dedicated years to changing the skill levels of
+technicians in the industry, they are very well needed / don't mistake my words here, however unless a company has faced litigation or
+facing requests on a regular basis that demand better results, then why would a company change!?!
+
+I've been trying (unsuccessfully) to get rid of free quotes for 5+ years in my company. We try to educate customers during maintenance
+visits and when scheduling equipment estimates, however only about 10-20% choose to go down our paid Home Performance Assessment path. Our
+installation process does follow the QI Standard for the items that pertain to the setup / commissioning of the installed equipment, however
+there is just no sustainable way for us to completely follow the items outlined in this article without charging for our time, because at
+the end of the day we still have to be competitive in our market.
+
+There are days that I can justify our actions to myself and also days that I just want to throw in the towel / not sacrifice our integrity.
+Integrity is something that I take very seriously, after all our companies tag line is _"Since 1954, Integrity is in the Housh!"_
+
+As mentioned, I'm not sure what the best path forward is! I hate to not have answers, but some problems are just complex and somewhat beyond
+our control.
+
+Let me know what you think some good solutions are.
+
+- Does your company follow the QI Standard?
+- What are resources that you've found helpful in educating your customers?

+coil bypass strategy at a high level, future posts will dive deeper into the features, benefits, as well as the challenges of this style of
+system.</p>
+<h2>What is a Coil Bypass</h2>
+<p>A coil bypass is not to be mistaken for a zoning system bypass, where airflow is “relieved” from the supply side of the system back into the
+return. Instead, a coil bypass diverts a portion of the airflow around the coil using a bypass damper(s). The bypass can serve several
+functions depending on the application, but in general it allows for a constant volume of air to be delivered to the space while the output
+of the coil can be shifted towards more or less dehumidification. In other words, it decouples the total system airflow from the coil
+airflow.</p>
+<p>The bypassed air mixes with the supply air stream to act as a reheat source, however unlike a typical reheat source it does not add more
+sensible load to the structure, instead it just brings the supply air temperature closer to the existing home’s temperature while still
+covering the latent and sensible loads of the home. A warmer duct system reduces the losses of the duct to unconditioned spaces as well as
+reduces the risk for duct condensation.</p>
+<p>The coil bypass strategy, as far as I know, was pioneered by <a href="https://www.linkedin.com/in/harry-boody-9b8a4366/">Harry Boody</a> of Energy
+Innovations and Scientific Environmental Design, Inc. However their websites are no longer active, so I’m not sure if they are still active
+in the HVAC design space or not.</p>
+<h2>The Problem</h2>

+<p>ASHRAE’s recommandation for the amount of air changes per hour (ACH) in a residential structure to be in the range of 3-5 ACH, and in
+general the higher the better, along with a MERV 13+ filter. In some / most cases the system airflow does not meet that criteria, especially
+low load homes or high volume homes.</p>
+<p>For example, let’s imagine a single story ranch home that is 2,500 square feet with 9 foot ceilings. This home is relatively tight
+construction and after doing the heating and cooling loads we’ve selected a 2.5 Ton system for this home. It is located in a green grass
+climate that needs some priority on dehumidification and requires an airflow of 350 CFM/Ton (875 CFM).</p>
+<p>We determine the volume of the conditioned space.</p>
+<p>2,500 x 9 = 22,500 ft^3</p>
+<p><img src="/articles/images/2023-08-10-volume-equation.png" alt="volume-equation" /></p>
+<table>
+<thead>
+<tr>
+<th><strong>Where:</strong></th>
+<th></th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td><strong>V</strong></td>
+<td><em>is the volume of the home</em></td>
+</tr>
+<tr>
+<td><strong>ACH</strong></td>
+<td><em>is the desired air changes per hour</em></td>
+</tr>
+<tr>
+<td><strong>60</strong></td>
+<td><em>conversion from hours to minutes</em></td>
+</tr>
+</tbody>
+</table>
+<p>Below is a table of the required CFM to meet the different air changes per hour.</p>
+<table>
+<thead>
+<tr>
+<th></th>
+<th align="center">CFM</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td>(22,500 x 3)/60</td>
+<td align="center"><strong><em>1,125 @ 3 ACH</em></strong></td>
+</tr>
+<tr>
+<td>(22,500 x 4)/60</td>
+<td align="center"><strong><em>1,500 @ 4 ACH</em></strong></td>
+</tr>
+<tr>
+<td>(22,500 x 5)/60</td>
+<td align="center"><strong><em>1,875 @ 5 ACH</em></strong></td>
+</tr>
+</tbody>
+</table>
+<p>As you can see we have a discrepency of meeting even the low end of 3 ACH. The high end of 5 ACH is over 2x the airflow for our 2.5 Ton
+system. The coil bypass strategy is one viable way, by decoupling the total system airflow from the coil airflow without, which eliminates
+the need of an auxilary fan / system that circulates air through some sort of filtration system.</p>
+<h3>Multi-Stage Systems</h3>
+<p>A challenge with multi-stage systems, even when sized properly, is that we often run at part-load conditions, and spend the majority of the
+time in lower stages. The lower stages often do worse at dehumidification than when running at full load.</p>
+<p>When the equipment runs in lower stages on a traditional system the total system airflow is reduced even further from the recommended air
+changes per hour. This reduced airflow also causes the throw of the air from the registers to be reduced which can lead to increased odds of
+stratification, poor air mixing, and increased potential for poor mean radiant temperatures (MRT) of the surfaces. The decreased airflow in
+low stages, lowers the velocity in the duct system, while low velocity is not a concern, it does increase the duct gains and increase the
+possibility of condensation on the ducts when they’re located outside of the thermal envelope of the building.</p>
+<p>Let’s imagine we have a duct system that has high wall registers located in a soffit at the interior wall that moves 100 CFM and we are
+trying to throw the air to the exterior wall which includes a window. The wall is @ 12 feet from the register. We’ve selected a register
+that meets the criteria, at high stage airflow it has a throw of 11.5 feet (shown as the green rectangle). When the system runs in low
+stage, the airflow is reduced to 70% of high stage (70 CFM), which would give us a throw from the register of @ 7 feet (shown as the red
+rectangle).</p>
+<p><img src="/articles/images/2023-08-10-register-throw.png" alt="register-throw" /></p>
+<p>The reduced flow through the register causes the air to only make it about 60% across the room before reaching it’s terminal velocity, which
+can cause the room to feel uncomfortable since the air never reaches the exterior wall and window.</p>
+<p>By decoupling the fan from the coil airflow it is possible to run in low stages, still have adequate dehumidification performance out of the
+system, and achieve the proper throw from the registers.</p>
+<h2>Conclusion</h2>
+<p>In this article we’ve begun to scratch the surface of what a coil bypass strategy is in an HVAC system, as well as some of the challenges
+that it can help solve. We’ve learned about why we may desire to decouple the total system airflow from the coil airflow.</p>
+<p>In future articles we will continue to explore some of the features, benefits, and challenges presented by such a strategy.</p>

+recently and it got me thinking about the industries tendency of offering free quotes. In this article, I’d like to just focus in on the
+items that are required as what I’m calling “prior to installation” items.</p>
+<h2>Prior to installation</h2>
+<ol>
+<li>Ensure ventilation calculations are performed.</li>
+<li>Building heat gain / loss calculation (Manual-J / Manual-N)
+<ol>
+<li>Room x room for new construction or duct modifications.</li>
+<li>Block load for existing (can use original if available).</li>
+</ol>
+</li>
+<li>Proper equipment capacity selection (Manual-S / Manual-CS)</li>
+<li>Properly matched systems (AHRI or CEE-AHRI)</li>
+</ol>
+<p>Let’s break the above items down to a rough estimated time to complete each of the items.</p>
+<table>
+<thead>
+<tr>
+<th>Item</th>
+<th>Time (minutes)</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td>Ventilation calculations</td>
+<td>15</td>
+</tr>
+<tr>
+<td>Manual-J (data gathering)</td>
+<td>30</td>
+</tr>
+<tr>
+<td>Manual-J (data entry / calculation)</td>
+<td>30</td>
+</tr>
+<tr>
+<td>Manual-S</td>
+<td>15</td>
+</tr>
+<tr>
+<td>AHRI</td>
+<td>15</td>
+</tr>
+<tr>
+<td><strong>Total</strong></td>
+<td>105</td>
+</tr>
+</tbody>
+</table>
+<blockquote>
+<p><em>The above items are obviously just estimations and the person’s experience in the different areas / tools they use. Some of the items are
+probably on the low side while others are probably on the high side.</em></p>
+</blockquote>
+<p>This is 1.75 hours just to do the calculations required to meet the QI Standard. This does not include any of the time spent with the
+customer building value in you or your product recommendations.</p>
+<p>When you want to not guess at some of the calculations then a blower door test is generally required in order to understand the leakage of
+the home, which adds even more time to the estimation process. Depending on the understanding you are looking for, the blower door test can
+add 30-180 minutes. This takes the total time to 2.25-4.75 hours.</p>
+<h2>Pushing boxes</h2>
+<p>The majority of residential HVAC companies make the bulk of their income off of equipment sales, so they have to “feed the beast” by
+skipping steps in both the installation of equipment and the sales process in order to close jobs and keep the ship afloat.</p>
+<p><img src="/articles/images/2023-10-04-sinking-boat.png" alt="sinking-boat" /></p>
+<p>This has helped contribute to these industry statistics:<a href="DOE" title="2018">^1</a></p>
+<ul>
+<li><strong>Incorrect refrigerant charge in greater than 50-80% of systems.</strong></li>
+<li><strong>Improper airflow:</strong>
+<ul>
+<li><strong>70% above the rated 0.5” w.c.</strong></li>
+<li><strong>47% above 0.7” w.c.</strong></li>
+<li><strong>85% undersized / inappropriate filter.</strong></li>
+</ul>
+</li>
+<li><strong>70-80% of systems have at least one fault.</strong></li>
+<li><strong>90-100% if duct leakage is considered.</strong></li>
+</ul>
+<h2>Consumer responsibility</h2>
+<p>Let me be clear, I don’t think that all the blame is on the industry here. The culture today is that everyone wants things for free and
+fast. They have been conditioned by online services and box stores. Should we not cater to those that aren’t willing to do their leg work?
+Is it really our fault, if they don’t care?</p>
+<h2>Liability</h2>
+<p>While it’s generally easy to shrug our shoulders and think that it’s ok to just continue on because all the competitors are doing the same
+thing. There is at least the possibility that skipping steps can come back to bite you. If things ever went to litigation and the steps
+outlined in the QI Standard are ignored, then there is high odds you would loose.</p>
+<p>No matter what you do to try and protect yourself (having customers sign-off, etc) does not adequately protect your company from litigation.
+There are stories out there where contractors were still held liable for not performing load calculations even though the consumer signed
+off on it, because it is not inline with “industry best practices.”</p>
+<h1>Summary</h1>
+<p>This has led me to the conclusion that free quotes are just bad for the industry in general. The path forward is a challenge (changing
+perception is hard). I don’t know that I have answers on what the best path forward is, to be frank, but I do know that our current <em>status
+quo</em> is subpar to say the least.</p>
+<p>Unfortunately, I don’t think the change is going to come from the industry, but that it’s going to require the consumer base to be more
+educated and demand more from the industry. There have been many organizations that have dedicated years to changing the skill levels of
+technicians in the industry, they are very well needed / don’t mistake my words here, however unless a company has faced litigation or
+facing requests on a regular basis that demand better results, then why would a company change!?!</p>
+<p>I’ve been trying (unsuccessfully) to get rid of free quotes for 5+ years in my company. We try to educate customers during maintenance
+visits and when scheduling equipment estimates, however only about 10-20% choose to go down our paid Home Performance Assessment path. Our
+installation process does follow the QI Standard for the items that pertain to the setup / commissioning of the installed equipment, however
+there is just no sustainable way for us to completely follow the items outlined in this article without charging for our time, because at
+the end of the day we still have to be competitive in our market.</p>
+<p>There are days that I can justify our actions to myself and also days that I just want to throw in the towel / not sacrifice our integrity.
+Integrity is something that I take very seriously, after all our companies tag line is <em>“Since 1954, Integrity is in the Housh!”</em></p>
+<p>As mentioned, I’m not sure what the best path forward is! I hate to not have answers, but some problems are just complex and somewhat beyond
+our control.</p>
+<p>Let me know what you think some good solutions are.</p>
+<ul>
+<li>Does your company follow the QI Standard?</li>
+<li>What are resources that you’ve found helpful in educating your customers?</li>
+</ul>

+				<p>Today, I’m releasing a command line application that is built on top of my
+<a href="https://github.com/swift-psychrometrics/swift-psychrometrics">swift-psychrometrics</a> package, that I open sourced over 2 years ago.</p>
+<p>The application consists of many calculations / conversions for psychrometric properties of an air stream. The tool works for both imperial
+and metric units. The application will work natively on macOS, but can also be ran through a <code>docker</code> container on other platforms.</p>
+<h2>Why</h2>
+<p>I spend a lot of time in my terminal, because I can work so much more efficiently. I discovered many years ago that the more I can do using
+simple applications and keyboard over a mouse and a web browser or native application the more I can accomplish. I understand this is
+intimidating for many who think they are <em>“not good with computers”.</em> I can assure that was me several years ago, I would only encourage you
+to not be afraid and give it a shot. We are at a time in society where it is easier than ever to get informed and learned new skills.</p>
+<h2>Installation</h2>
+<p>For complete installation instructions, you can view the <a href="https://github.com/swift-psychrometrics/psychrometrics-cli">github</a> repository.</p>
+<p>The following instructions are based on using macOS.</p>
+<h3>Open your terminal application.</h3>
+<p>Personally, I use <a href="https://iterm2.com/">iTerm2</a>, however you can use the default <code>Terminal</code> app. Found at
+<code>/Applications/Utilities/Terminal.app</code>.</p>
+<h2>Install Homebrew</h2>
+<p>We use <a href="https://brew.sh">Homebrew</a> for package distribution of the pre-built application binaries. You can follow their instructions to
+install.</p>
+<h3>Tap our custom formula tap.</h3>
+<pre><code class="language-bash">brew tap swift-psychrometrics/formula
+</code></pre>
+<h3>Install the psychrometrics application</h3>
+<pre><code class="language-bash">brew install psychrometrics
+</code></pre>
+<p>That’s it!</p>
+<h2>Usage</h2>
+<p>I will run through a couple of the commands that are supplied with the application and show what you can expect the outputs to be.</p>
+<h3>Properties</h3>
+<p>The following command will output a bunch of the psychrometric properties of an air stream. There are several ways to call it, but generally
+you will supply the dry bulb temperature and the relative humidity.</p>
+<p>Below, we calculate the psychrometric properties based on 75°F and 50% humidity.</p>
+<pre><code class="language-bash">psychrometrics --dry-bulb 75 --relative-humidity 50
+</code></pre>
+<p><img src="/articles/images/2023-09-18-properties.png" alt="properties-output" /></p>
+<h3>Dehumidifier Sizing</h3>
+<p>If you’ve read some of my recent articles on calculating the
+<a href="https://mhoush.com/posts/sizing-dehumidifier-by-latent-load/">dehumidifier size required based on the latent load</a>, the application also
+ships with a calculation that will do this for you and has the ability to calculate it at different <code>coverages</code> that you can supply.</p>
+<p>For example if we’ve done a load calculation and determined that we have a latent load of <code>4,334 BTU/h</code> then we could run the following
+command to see what size dehumidifier is needed for <code>100%, 85%, and 70%</code> of the latent load.</p>
+<pre><code class="language-bash">psychrometrics dh size --coverage 100 85 70 --verbose 4334
+</code></pre>
+<p><img src="/articles/images/2023-09-18-dh-size.png" alt="dh-size" /></p>
+<h3>Pounds of Water Removed</h3>
+<p>I also recently wrote an article about <a href="https://mhoush.com/posts/pounds-of-water-removed/">calculating the pounds of water removed</a> from an
+air stream given the grains of moisture removed.</p>
+<p>Below is an example of calculating the pounds of water removed per hour based on the example in the article (14 delta-grains)</p>
+<pre><code class="language-bash">psychrometrics dh pounds-removed --delta 14 --cfm 797 --verbose
+</code></pre>
+<p><img src="/articles/images/2023-09-18-pounds-removed.png" alt="pounds-removed" /></p>
+<h3>Help</h3>
+<p>You can use <code>--help</code> option to show help and the list of commands provided.</p>
+<p><img src="/articles/images/2023-09-18-help.png" alt="help" /></p>
+<p>If you have any questions then feel free to email or message me. I hope some of you may find this application useful.</p>

+				<p>This is part one of a series of articles to help HVAC technicians (or others) get started in developing their skills to program. This can
+help to automate everyday tasks or just familiarize themselves with some of the tools used by programmers.</p>
+<h2>Why</h2>
+<p>I think if nothing else, this series can help gain knowledge, tips, and tricks to make you more comfortable with your computer. I hope that
+you will at least learn how to use your <code>terminal</code> application and more specifically <code>vim</code> motions and keybindings (more on that in another
+article).</p>
+<p>The goal of this article is to just get a machine setup with tools and to start exploring. I am a shill for <code>macOS</code>, so all of these will be
+specifically geared towards that and my workflows, most everything that is showcased should also work on <code>linux</code> machines (not sure about
+<code>windows</code>), although you may have to search for specific instructions on installing software for other platforms.</p>
+<p>What I have learned on my journey in programming is that the more you can lean on small software packages that focus on a single task, but
+do them well, the better. The less you use your mouse, the more productive you can be. The more you can work with <code>text</code> files and formats
+the more portable and transformable your workflows can be.</p>
+<h2>Getting Started</h2>
+<p>The first thing that we will focus on is becoming familiar with the terminal application. On macOS the terminal application is located at
+<code>/Applications/Utilities/Terminal.app</code>. However, rather than click around to find it, you can use the <code>⌘&lt;space&gt;</code> to pull up your spotlight
+search, then type <code>Terminal</code> to select the terminal application.</p>
+<p><img src="/articles/images/2023-09-21-spotlight.png" alt="spotlight" /></p>
+<h3>Terminal Overview</h3>
+<p>Your terminal is a program that allows you to run programs by typing commands into it’s window. There are a lot of built-in commands and a
+bunch that you can install. The terminal is very customizable (and once familiar, you will constantly be tweaking / adjusting to suit your
+needs). Right now customization is not what we will focus on, however in future articles I will provide tips and tricks on customizing it.
+Right now, we only need to know how to open it up and type in commands.</p>
+<p><img src="/articles/images/2023-09-21-terminal.png" alt="terminal" /></p>
+<p>Below is an image / explanation of what the default status line includes.</p>
+<p><img src="/articles/images/2023-09-21-terminal-line.png" alt="terminal-line" /></p>
+<h3>Learn Basic Commands (Built-in)</h3>
+<p>Here are a few basic commands that you should familiarize yourself with, as you will use them often when working inside of a terminal.</p>
+<h3>Change Directory</h3>
+<p><code>cd</code> (change directory) is the command that allows you to move around your file system when inside the terminal.</p>
+<blockquote>
+<p><strong>Note:</strong> <code>~</code> is a representation of your <code>Home</code> directory.</p>
+</blockquote>
+<pre><code class="language-bash">cd ~/Documents
+</code></pre>
+<p>The above command will move you into your Documents directory.</p>
+<blockquote>
+<p><strong>Note:</strong> If there are spaces in the name of the directory you try to move to then the easiest way is to wrap the name in quotes.</p>
+</blockquote>
+<pre><code class="language-bash">cd &quot;~/Documents/Product Concepts&quot;
+</code></pre>
+<p>Some other things to understand when moving around / supplying arguments to the <code>cd</code> command.</p>
+<p>You can use <code>..</code> to go backwards / move up to the parent directory. For example, say we are in the <code>~/Documents</code> directory, to go back up to
+the home directory we could use the following:</p>
+<pre><code class="language-bash">cd ..
+</code></pre>
+<p>These can be chained together as well. For example say we are located in the <code>~/Documents/Product Concepts</code> directory, we could use the
+following to go up two directory levels back to the home directory.</p>
+<pre><code class="language-bash">cd ../..
+</code></pre>
+<blockquote>
+<p><strong>Pro-Tip:</strong> You can use the <code>&lt;tab&gt;</code> key when navigating to auto-complete, generally typing a few characters followed with the <code>&lt;tab&gt;</code> key
+will auto-complete for you.</p>
+</blockquote>
+<h3>List files</h3>
+<p>Use <code>ls</code> to output a list of files and directories where you are located.</p>
+<pre><code class="language-bash">ls
+</code></pre>
+<p><em>Example Output when in my ~/Documents directory</em></p>
+<pre><code class="language-bash">Estimates.app
+InkscapeDrawings
+KwikModel
+MyAparment
+NCISummit
+Personal
+Product Concepts
+Receipts.receipts
+RingCentral
+SketchUP
+Tech-Tips
+desktop.ini
+espanso-migrate-backup
+espanso-migrate-backup-2
+</code></pre>
+<p>Using options with <code>ls</code> to show more statistics and hidden files. There are often hidden files on your computer that are used for
+application support or other purposes, these files are not shown using the default command. Hidden files start with a <code>.</code>, below is an
+example of showing hidden files in your home directory.</p>
+<pre><code class="language-bash">ls -la ~/
+</code></pre>
+<blockquote>
+<p><strong>Note:</strong> Above I added the <code>~/</code> which will allow you to list the files in your home directory even if you currently are not there in your
+terminal, if you were already there (for example by using <code>cd ~/</code> then you would not need to use that at the end of the command.</p>
+</blockquote>

+</code></pre>
+<p>As you can see, I have a lot of hidden files and folders, your output will probably look much different than mine.</p>
+<h3>Clearing the Terminal</h3>
+<p>Often times you may want to clear the terminal screen. You can use the <code>clear</code> command to clear the screen of the terminal.</p>
+<pre><code class="language-bash">clear
+</code></pre>
+<p>Or use a keyboard shortcut <code>⌃l</code> (<code>&lt;control&gt;l</code>)</p>
+<h3>Creating Directories</h3>
+<p>Use <code>mkdir</code> (make directory) to create a directory.</p>
+<p>First, let’s move into the <code>tmp</code> directory, the <code>tmp</code> directory is a directory on your file system that is typically used for applications
+to write temporary logs / files to, it get’s erased everytime your computer is restarted. We can use the <code>cd</code> command that we learned
+earlier.</p>
+<pre><code class="language-bash">cd /tmp
+</code></pre>
+<p>Next, let’s create a new directory called “MyDirectory”.</p>
+<pre><code class="language-bash">mkdir MyDirectory
+</code></pre>
+<h4>Gotcha’s with ‘mkdir’</h4>
+<p>By default you can’t create directories that are multiple levels deep, unless the directories already existed or we provide the <code>-p</code> option.
+For example, if we want to create a directory at <code>/tmp/MyOtherDirectory/Nested/Deeply</code> then we could use the following command when inside
+the <code>tmp</code> directory.</p>
+<pre><code class="language-bash">mkdir -p MyOtherDirectory/Nested/Deeply
+</code></pre>
+<p>Now, try out using the <code>&lt;tab&gt;</code> key with the <code>cd</code> command to navigate to the <code>Deeply</code> folder.</p>
+<pre><code class="language-bash">cd MyOther &lt;tab&gt; &lt;tab&gt; &lt;tab&gt;
+</code></pre>
+<h3>Open Command</h3>
+<p>You can use the open command to open files or folders in the default application for the file type.</p>
+<p>For example, if we want to open a <code>Finder</code> window while in the <code>/tmp</code> directory, we can use the following command:</p>
+<pre><code class="language-bash">open .
+</code></pre>
+<h3>Manual Pages</h3>
+<p>Lastly, to learn more about commands you can use the <code>man &lt;command&gt;</code>. To bring up the manual pages for the command in the terminal. You can
+use the arrow keys to navigate around the manual pages and type the letter <code>q</code> to quit / close the manual pages.</p>
+<pre><code class="language-bash">man ls
+</code></pre>
+<p>That is it for the first installment in this series. I hope you learned something and have better understanding of using your terminal.</p>

+<a href="https://mhoush.com/posts/introduction-to-programming-for-hvac-1/">first</a> article in the series where we learned about using your terminal.
+This article builds upon that foundation.</p>
+<h2>What is a Package Manager</h2>
+<p>A package manager is a piece of software that helps to install software and manage updates for your system. For me, the first thing that I
+do with a new machine is install <code>Homebrew</code>. <a href="https://brew.sh">Homebrew</a> is my preferred package manager for <code>macOS</code>.</p>
+<h2>Why</h2>
+<p>A package manager is nice because often software relies / requires other dependencies in order to work properly. By using a package manager
+it will make sure that the correct dependencies are installed for the software that you need to run. It allows you to be able to update and
+manage software through a centralized interface.</p>
+<h2>Installation</h2>
+<p>Installation is simple. Open up your terminal and enter the following command (easiest to just copy / paste from the homepage linked above).</p>
+<pre><code class="language-bash">/bin/bash -c &quot;$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)&quot;
+</code></pre>
+<p>This will prompt you for your password in order to create some directories and install the required software for <code>brew</code> to work. The
+installation may take some time, while it downloads the command line tools for <code>Xcode</code>.</p>
+<p>When completed, follow the <code>Next Steps</code> and copy / paste the command listed, that should look like below.</p>
+<pre><code class="language-bash">(echo; echo 'eval &quot;$(/opt/homebrew/bin/brew shellenv)&quot;') &gt;&gt; /Users/&lt;you&gt;/.zprofile
+eval &quot;$(/opt/homebrew/bin/brew shellenv)&quot;
+</code></pre>
+<p><img src="/articles/images/2023-09-22-brew-output.png" alt="brew-output" /></p>
+<p>The first line of this command sets up some things in your shell profile (which we have not discussed yet) that will make <code>Homebrew</code>
+available to you anytime you start a new session in your terminal. The second line of the command makes it available in your current
+terminal session.</p>
+<p>Next run the following command and make sure that everything is setup correctly.</p>
+<pre><code class="language-bash">brew doctor
+</code></pre>
+<p>Which should output the following:</p>
+<pre><code>Your system is ready to brew.
+</code></pre>
+<h3>Terminology</h3>
+<p>Homebrew calls command line applications <code>formula</code> and normal graphical applications <code>casks</code>. It has the ability to install both styles of
+applications.</p>
+<h2>Search Command</h2>
+<p>The following command is used to search for software packages:</p>
+<pre><code class="language-bash">brew search chrome
+</code></pre>
+<h2>Open a Homepage</h2>
+<p>The following command can be used to view the homepage of a formula or cask in your browser:</p>
+<pre><code class="language-bash">brew home google-chrome
+</code></pre>
+<h2>Update Homebrew</h2>
+<p>The following command is used to update homebrew:</p>
+<pre><code class="language-bash">brew update
+</code></pre>
+<h2>Update packages installed on your system</h2>
+<p>The following command is used to update software that is installed / managed by homebrew.</p>
+<pre><code class="language-bash">brew upgrade
+</code></pre>
+<p>You can combine the update and upgrade commands, which will update homebrew and upgrade all the software it manages on you machine with the
+following command.</p>
+<pre><code class="language-bash">brew update &amp;&amp; brew upgrade
+</code></pre>
+<h2>Conclusion</h2>
+<p>That is it for this article. I will say that for me, when I find a piece of software that I want to use, I generally try to search for it in
+<code>brew</code> first, before installing it via other means.</p>
+<p>I hope you’ve found this article helpful. In the next article we will start to use the skills that we’ve learned in these first two articles
+and write our first program / script.</p>

+				<p>In this article we will put together some of the pieces from the last 2 articles, and build our first program. If you have missed the first
+articles, then you can catch up <a href="https://mhoush.com/series/programming-for-hvac/">here</a> before continuing with this article.</p>
+<h2>Getting Started</h2>
+<p>We are going to make our first script / program. This first program is really just setting up some building blocks for our next program we
+will write, that will remove the background from an image.</p>
+<h3>Creating a scripts directory</h3>
+<p>We learned in the <a href="https://mhoush.com/posts/introduction-to-programming-for-hvac-1/">first article</a> how to use our terminal. Today we are
+going to use some of the commands we learned to create a directory where we can store our script and future scripts that we write.</p>
+<p><strong>Create a directory</strong></p>
+<pre><code class="language-bash">mkdir -p ~/.local/bin
+</code></pre>
+<p>The above command will create a “hidden” directory in your home folder. We can go ahead and move into the directory we just created.</p>
+<blockquote>
+<p><strong>Note:</strong> The <code>-p</code> option allows us to create nested directories if the parent directory doesn’t exist.</p>
+</blockquote>
+<pre><code class="language-bash">cd ~/.local/bin
+</code></pre>
+<h3>Hello World</h3>
+<p>It is common in programming to start out with a “Hello World” program when learning a new scripting paradigm. So let’s jump in and get
+started.</p>
+<p><strong>Creating our script file:</strong></p>
+<pre><code class="language-bash">touch hello-world.sh
+</code></pre>
+<p><strong>Now open the file:</strong></p>
+<pre><code class="language-bash">open hello-world.sh
+</code></pre>
+<p>The above command should open the file in the <code>TextEdit</code> application. In order to make the text edit application to not auto-capitalize
+words and play more nicely, we need to adjust some settings. Open the settings by pressing <code>⌘,</code>.</p>
+<p>In the <strong>Format</strong> section, select <em>Plain text</em> and in the <strong>Options</strong> section de-select <em>Check spelling as you type</em>.</p>
+<p><img src="/articles/images/2023-09-24-text-settings.png" alt="text-settings" /></p>
+<p>At this point for changes to take place, you will need to close the file and re-open.</p>
+<blockquote>
+<p><strong>Tip:</strong> In your terminal you can run the last command in your history by using the <code>↑</code> (Up) arrow key.</p>
+</blockquote>
+<p>Now that the file is open again, we will write our hello-world program. The contents of your file should look like the following:</p>
+<pre><code class="language-bash">#!/bin/sh
+
+echo 'Hello World!'
+</code></pre>
+<p>The first line is referred to as the <code>shebang</code>, this tells your computer which shell interperter to run your file. I have not explained the
+shell yet, but it currently would just muddy the waters a bit, but there are several shell interperters on your computer with the <code>sh</code> posix
+shell being one of the most universal / lowest level ones, which is why I’m choosing this one (in other words this script would work on just
+about any machine you were on).</p>
+<p>The second line we are using the built-in <code>echo</code> command and passing it the ‘Hello World!’ argument.</p>
+<p>Now save and close the file <code>⌘s</code> (to save) <code>⌘q</code> (to quit the text edit application).</p>
+<p><strong>Run the program from your terminal:</strong></p>
+<pre><code class="language-bash">/bin/sh hello-world.sh
+</code></pre>
+<p>You should see that <code>Hello World!</code> was printed to your console.</p>
+<p><img src="/articles/images/2023-09-24-hello-output.png" alt="hello-output" /></p>
+<h3>Make Executable</h3>
+<p>Now that we have our basic script working, let’s make it an executable.</p>
+<p><strong>In your terminal, type the following:</strong></p>
+<pre><code class="language-bash">chmod u+x hello-world.sh
+</code></pre>
+<p>This will change the mode of the file type to be an executable.</p>
+<p>Now move / rename the file so we don’t have to call it using <code>.sh</code> extension:</p>
+<pre><code class="language-bash">mv hello-world.sh hello-world
+</code></pre>
+<p>Now that the file is executable, we can execute it by just calling the name of the file.</p>
+<pre><code class="language-bash">./hello-world
+</code></pre>
+<blockquote>
+<p><strong>Note:</strong> We have to prefix the file name with <code>./</code> in the above command so that it knows where to find our file. The <code>./</code> is saying run
+this file in our current directory. In the future we will setup our shell so that it knows to look in our <code>~/.local/bin</code> directory for
+scripts, so that we can call them without this prefix.</p>
+</blockquote>
+<h2>Conclusion</h2>
+<p>Congratulations, in this article we wrote our first program. We learned how to edit the file, set it’s permissions, and execute the program
+from our terminal. I should mention that the <code>TextEdit</code> application is generally not how you would program, people typically use what is
+known as an <code>IDE (integrated development environment)</code>, however I chose to use the <code>TextEdit</code> application because it is built-in to <code>macOS</code>
+and allowed us to accomplish our goal without downloading other software.</p>
+<p>In our upcoming articles, we will write a program that I hope is useful to you / something that you can build upon and use for a long time.
+Thank you for reading to this point.</p>

+before continuing with this article.</p>
+<h2>Arguments</h2>
+<p>Before we start creating our program that will remove the background from images let’s go over arguments in shell scripts. Arguments are
+supplied to shell scripts are separated by a space <code>&quot; &quot;</code>, as opposed to options which start with a <code>-&lt;character&gt;</code> or <code>--&lt;word&gt;</code>.</p>
+<p>To illustrate this, let’s change our <code>hello-world</code> script we wrote in the last article.</p>
+<p><strong>Move into our scripts directory:</strong></p>
+<pre><code class="language-bash">cd ~/.local/bin
+</code></pre>
+<p><strong>Make a copy of the hello-world script:</strong></p>
+<pre><code class="language-bash">cp hello-world greet
+</code></pre>
+<p>Above we make a copy of the hello-world file and name the copy <code>greet</code>.</p>
+<p><strong>Open the greet file:</strong></p>
+<pre><code class="language-bash">open -a TextEdit greet
+</code></pre>
+<blockquote>
+<p><strong>Note:</strong> Because the greet file is an executable, in order to open it in the <code>TextEdit</code> application we must supply the <code>-a</code> option.
+Otherwise it will just run our <code>greet</code> program in another terminal. Use <code>man open</code> to read more about the open command.</p>
+</blockquote>
+<p><strong>Edit the greet file:</strong></p>
+<pre><code class="language-bash">#!/bin/sh
+
+echo &quot;Hello, ${1}!&quot;
+</code></pre>
+<p>Make sure to save <code>⌘s</code> the file.</p>
+<p>Take note that the quotes need to be changed to <code>&quot;</code> (double quotes) from our original <code>hello-world</code> program.</p>
+<p>The <code>${1}</code> is indicating that we will insert / interpret the first argument passed to our program and insert it at that location. Arguments
+are interpreted in order they are passed in with <code>${0}</code> always representing the filename of the program that is called (generally not needed
+/ used in your scripts).</p>
+<p><strong>Test it out:</strong></p>
+<pre><code class="language-bash">./greet Michael
+</code></pre>
+<p><img src="/articles/images/2023-09-26-greet-output.png" alt="greet-output" /></p>
+<p>If you’d like to supply multiple words (or arguments that contain spaces) as a single argument then you can wrap them in quotes.</p>
+<pre><code class="language-bash">./greet &quot;Michael Housh&quot;
+</code></pre>
+<blockquote>
+<p><strong>Tip:</strong> Wrapping in quotes is especially useful for commands that take file paths, if any of the folders or file names contain spaces.</p>
+</blockquote>
+<h2>More Useful Program</h2>
+<p>At this point, it’s time to build a more useful program that we can use. First, we must download some dependencies for our program.</p>
+<p><strong>Install imagemagick:</strong></p>
+<pre><code class="language-bash">brew install imagemagick
+</code></pre>
+<blockquote>
+<p><strong>Note:</strong> If you’d like to check out the documentation / website for imagemagick you can run <code>brew home imagemagick</code>.</p>
+</blockquote>
+<p>This will take a bit for brew to install imagemagick and it’s dependencies. When it’s completed, we can check to make sure that imagemagick
+is installed by running the following command.</p>
+<pre><code class="language-bash">magick --version
+</code></pre>
+<p>It should output something along the lines of this below.</p>
+<pre><code class="language-bash">Version: ImageMagick 7.1.1-17 Q16-HDRI aarch64 21569 https://imagemagick.org
+Copyright: (C) 1999 ImageMagick Studio LLC
+License: https://imagemagick.org/script/license.php
+Features: Cipher DPC HDRI Modules OpenMP(5.0)
+Delegates (built-in): bzlib fontconfig freetype gslib heic jng jp2 jpeg jxl lcms lqr ltdl lzma openexr png ps raw tiff webp xml zlib
+Compiler: gcc (4.2)
+</code></pre>
+<blockquote>
+<p><strong>Tip:</strong> Don’t forget, you can use the <code>clear</code> command to clear the terminal.</p>
+</blockquote>
+<p><strong>Create our script:</strong></p>
+<pre><code class="language-bash">touch mktrans
+</code></pre>
+<p>We are going to name our script <code>mktrans</code> as a short for make transparent.</p>
+<p><strong>Open the file:</strong></p>
+<pre><code class="language-bash">open mktrans
+</code></pre>
+<p><strong>The program:</strong></p>
+<pre><code class="language-bash">#!/bin/bash
+
+# The input file path, passed in as the first argument.
+inputfile=&quot;${1}&quot;
+
+# The color to make transparent, optionally passed in as the second argument.
+# by default we handle / make white backgrounds transparent.
+color=&quot;${2:-white}&quot;
+
+# Use the built-in basename command to normalize the input file name
+# this will convert a file path, such as ~/Pictures/my-image.png to my-image.png.
+fullfilename=$(basename -- &quot;$inputfile&quot;)
+
+# Use the text of the `fullfilename` up to the first '.' as the file name.
+filename=&quot;${fullfilename%%.*}&quot;
+
+# Use the text after the last '.' as the file extension.
+extension=&quot;${fullfilename##*.}&quot;
+
+# Create the output file name to use.
+#
+# For an input file of `input.png`, our output name would be
+# `input-transparent.png`.
+#
+# This will output the file in the directory that we are
+# in when we use our script (which may different than where
+# the image is located)
+outputfile=&quot;${filename}-transparent.${extension}&quot;
+
+# Make the magick happen :)
+convert &quot;${inputfile}&quot; -fuzz 10% -transparent &quot;${color}&quot; &quot;${outputfile}&quot;
+
+</code></pre>
+<p>I’ve included comments in the program above, which is good practice, as there is high odds that you will forget what is going on when / if
+you open the file up in the future to look at it. We are using a lot of what is called parameter expansion magic in this file. You can read
+up more on what we are doing in the <a href="https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html">bash documentation</a>.</p>
+<p>This script is far from perfect, there are a lot of things to be improved upon. For example, if you download / save the banner image of this
+post and run this script, it will also remove some color in the wizards beard, eyes, and eye brows. However, it does work very well for my
+general use case, which is to remove the background from screenshots of pdf documents. It should be noted that it will not work on all types
+of images, some image types do not allow transparency, so it is safest to call this with input image being a <code>.png</code> image type, however you
+can use the <code>imagemagick</code> program that we downloaded to convert other image types to <code>.png</code>, but that will be left up to you to figure out.</p>
+<h2>Using Our Program</h2>
+<p>This is going to assume that you have download the banner image at the top of this article. You can do this by right-clicking and choosing
+<code>Save As</code>. This should save the image in your downloads folder, and you can keep the name of <code>part4-banner.png</code>.</p>
+<p><strong>Make the program executable:</strong></p>
+<pre><code class="language-bash">chmod u+x mktrans
+</code></pre>
+<p><strong>Make the image background transparent:</strong></p>
+<pre><code class="language-bash">./mktrans ~/Downloads/part4-banner.png
+</code></pre>
+<p><strong>Open the image:</strong></p>
+<pre><code class="language-bash">open part4-banner-transparent.png
+</code></pre>
+<p>It should look like below.</p>
+<p><img src="/articles/images/2023-09-26-part4-banner-transparent.png" alt="banner-transparent" /></p>
+<blockquote>
+<p><strong>Note:</strong> If you are viewing this site in <em>light</em> mode, the image does not look that bad. Hit the moon button in the top above my profile
+image to see some of the flaws of our program.</p>
+</blockquote>
+<hr />
+<blockquote>
+<p><strong>Tip:</strong> Remove the image from the <code>~/.local/bin</code> by using <code>rm part4-banner-transparent.png</code>. Be aware that the <code>rm</code> command can not be
+undone, so use with caution / knowledge. It is safer, until you are more comfortable to use the <code>Finder</code> application and move the file to
+the trash. In <code>Finder</code>, you can show hidden directories by typing <code>⌘.</code> or go directly to the folder by typing <code>⇧⌘G</code> (shift + command + G)
+and in the pop-up typing <code>~/.local/bin</code>.</p>
+</blockquote>
+<hr />
+<p>That is it for this article. In the upcoming articles we will setup our <code>shell</code> environment so that we can use the commands we’ve built
+without having to navigate to the <code>~/.local/bin</code> directory. Thank you for reading to the end, I hope you’re finding this series helpful.</p>

+				<p>This is an article that shows how to calculate the pounds of water removed from an air stream, given the entering conditions (return air
+stream) and the outlet conditions (supply air stream).</p>
+<p>This is useful in the field when you want to calculate the amount of moisture removed from an air-conditioner or a dehumidifier. This
+article assumes that you have knowledge of a psychrometric chart. If you do not have basic knowledge of the psychrometric chart, then here
+are a couple articles to familiarize yourself.</p>
+<h2>Articles</h2>
+<ul>
+<li><a href="https://hvacrschool.com/understand-dew-point-absolute-moisture-right-side-psych-chart/">Understand Dew-Point</a></li>
+<li><a href="https://hvacrschool.com/the-impact-of-adding-or-removing-water-from-air/">Impact of Adding or Removing Water from Air</a></li>
+</ul>
+<h2>Scenario</h2>
+<p>Let’s imagine that we have an air-conditioner that has the following measurements taken:</p>
+<ul>
+<li>Return Air: 75° / 50% RH</li>
+<li>Supply Air: 55° / 81% RH</li>
+</ul>
+<p>We plot the two values on the psychrometric chart (black line represents the return air conditions and blue line represents the supply air
+conditions).</p>
+<p><img src="/articles/images/2023-09-08-pounds-of-water-removed.png" alt="chart" /></p>
+<p>We start by finding the corresponding dry-bulb temperature at the bottom of the chart and draw a straight line up to where it intersects the
+relative humidity curve. After that we draw a straight line to the right side of the psychrometric chart to find the grains of moisture per
+pound of air.</p>
+<p>This gives us the following values:</p>
+<ul>
+<li>Return Air: 66 gr/lb</li>
+<li>Supply Air: 52 gr/lb</li>
+</ul>
+<p>We can then use the following formula to calculate the pounds of water removed.</p>
+<p><img src="/articles/images/2023-09-08-formula.png" alt="formula" /></p>
+<table>
+<thead>
+<tr>
+<th><strong>Where</strong></th>
+<th></th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td><strong>W</strong></td>
+<td><em>Weight of water in pounds per hour</em></td>
+</tr>
+<tr>
+<td><strong>4.5</strong></td>
+<td><em>Constant based on density / specific heat of moist air</em></td>
+</tr>
+<tr>
+<td><strong>CFM</strong></td>
+<td><em>Airflow in cubic feet per minute</em></td>
+</tr>
+<tr>
+<td><strong>∆G</strong></td>
+<td><em>Difference in grains of moisture</em></td>
+</tr>
+<tr>
+<td><strong>7000</strong></td>
+<td><em>Constant based on grains of moisture in saturated air</em></td>
+</tr>
+</tbody>
+</table>
+<h2>Solution</h2>
+<p>First, we solve for the difference in grains between the two air streams.</p>
+<p>∆G = 66 - 52 = 14</p>
+<p>Next, we’ve measured our airflow and have determined to have <strong>797 CFM</strong> of airflow across the evaporator coil, so we can substitute our
+values into the formula.</p>
+<p><img src="/articles/images/2023-09-08-solution.png" alt="solution" /></p>
+<p>So, we are removing about 7 pounds of water per hour at these conditions.</p>
+<p>Another thing to note is that 1 pound of water is approximately 1 pint of water, which can be useful when working with dehumidifiers that
+can often be rated in pints per day.</p>
+<p>I hope you’ve found this article helpful, thanks for reading!</p>

+<h2>What is an RSS Feed</h2>
+<p>An RSS feed will show you new posts, generally from a blog, without having to remember to check the website at regular intervals or signup
+for an email list for notifications.</p>
+<p>NetNewsWire puts an RSS feed as:</p>
+<p><strong>It’s like podcasts</strong> - but for <em>reading.</em></p>
+<p>You consume an RSS feed, using an RSS reader application or extension in your browser.</p>
+<h2>Step One</h2>
+<p>First find and download an RSS reader, you can download <a href="https://netnewswire.com">NetNewsWire</a> for macOS from the link, or for iOS from the
+<a href="https://apps.apple.com/us/app/netnewswire-rss-reader/id1480640210">AppStore</a>.</p>
+<h2>Step Two</h2>
+<p>Add the rss feed to stay up to date when I publish new articles.</p>
+<ol>
+<li>Click the plus in the right side of the sidebar and select <code>New Feed...</code></li>
+<li>In the URL field add: <code>https://mhoush.com/articles/feed.xml</code></li>
+<li>Optionally give it a name</li>
+<li>Click the <code>Add</code> button.</li>
+</ol>
+<p><img src="/articles/images/2023-08-10-rss-feed.gif" alt="rss gif" /></p>

+				<p>This is a quick article to show how to calculate the size of dehumidifier needed based on the latent load of a building. This is useful if
+you’ve done a load calculation and know the latent load of the structure.</p>
+<h2>Formulas</h2>
+<p>The formula above is used to solve for the pints per hour required to size a dehumidifier.</p>
+<table>
+<thead>
+<tr>
+<th>Where</th>
+<th></th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td>Ql</td>
+<td>Latent load</td>
+</tr>
+<tr>
+<td>Ph</td>
+<td>Pints / hour</td>
+</tr>
+</tbody>
+</table>
+<p>We can then convert to pints per day by multiplying the answer by 24 hours, below is the combined formula.</p>
+<p><img src="/articles/images/2023-09-15-pints-per-day.png" alt="pints-per-day-formula" /></p>
+<table>
+<thead>
+<tr>
+<th>Where</th>
+<th></th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td>Ql</td>
+<td>Latent load</td>
+</tr>
+<tr>
+<td>Pd</td>
+<td>Pints / day</td>
+</tr>
+</tbody>
+</table>
+<p>In some cases you may want to size the dehumidifier for less than the full latent load, assuming that the air-conditioner (when sized
+properly) is going to cover the full latent load when at peak design temperatures and that the peak latent period for your area is during
+peak cooling demand.</p>
+<h2>Example</h2>
+<p>Let’s imagine we have done a load calculation and have a latent load of 4,334 BTU/h. So, plugging that into our above formula.</p>
+<p><img src="/articles/images/2023-09-15-pints-per-day-example.png" alt="pints-per-day-formula-example" /></p>
+<p>Or if we just want to cover the latent capacity at 85% of the full latent load.</p>
+<p><img src="/articles/images/2023-09-15-pints-per-day-example2.png" alt="pints-per-day-formula-example" /></p>
+<p>This gives us some guidance that we would need to select a dehumidifier that is rated for 84-99 pints per day, depending on which condition
+we wanted to use.</p>
+<p>I don’t feel oversizing a dehumidifier, within reason, is that problematic (or at least it does not come with the same problems as an
+oversized air conditioner), so I would personally go for a 100-120 pint per day model dehumidifier in this application.</p>
+<p>Thanks for reading!</p>

+				<p>In this general article, I explain why I don’t generally like to use mini-splits.</p>
+<h2>The Positive Sides</h2>
+<p>When people say mini-splits, in general we mean “ductless” style units. These can either be high wall, floor mounted, or ceiling mounted
+consoles. These units do offer really high efficiency and becuase they’re “ductless” you don’t have duct gains/losses.</p>
+<p>These units are common in many other countries and have been around for a long time. They do are generally quick and fairly easy to install,
+but are mostly a pain in the tail to work on.</p>
+<p>So, the plus side to these units are that they are really efficient, they generally have models that have a high-heat output for colder
+climates, although this option is becoming more prevelant in traditional unitary style heat pumps as well. You do not have heat gains or
+losses due to ductwork being in unconditioned spaces.</p>
+<h2>The Down Sides</h2>
+<p>Most mini-split systems do not do the greatest at humidity removal. This is partially because they use proprietary algorithms to control the
+blower and compressor. They do achieve long run-times, which is often good for comfort stand points, however there is generally not a good
+way to control / hack them to work towards achieving good IAQ.</p>
+<p>These units offer next to no filtration, so in order to have filtration you need to utilize a stand-alone / portable filtration means. Which
+a lot of the portable filtration systems have problems of their own (come bundled with UV / PCO technology or other “space” technology that
+can lead to their own IAQ problems). It also introduces another fan, which may / may not be that efficient. In other words, when considering
+other items to make them more comparable to what a traditional system offers, are they really that much more efficient?</p>
+<p>These systems also do not have a good method of offering basic fresh air control / management, so other systems, such as an ERV need to be
+installed to handle the fresh air requirements of the building.</p>
+<p>The controls for these systems are often hard to understand / use. They do allow you to change fan speeds, but they control the compressor.
+The fans often run all the time, which is not necessarily a bad thing, but they don’t really offer many ramping profiles or adjustments to
+change the blower speed when the compressor is off vs. on.</p>
+<p>These systems get dirty quickly, are generally a pain to clean properly, and are not easily repairable. Manufacturer support is often poor,
+the documents aren’t always translated very well, and most technicians hate to work on them.</p>
+<h1>What about ducted models?</h1>
+<p>But what about the ducted models? Well, the ducted models are a step in the right direction. You can use filters on them, although some of
+the manufacturer’s do not recommend installing better / improved filter cabinets (like a 4-5” media filter), however we have done that
+successfully many times and always include media filters as an option on our installations, but you do need to make sure that they have a
+very low pressure drop, as they a lot are not designed for very much static pressure.</p>
+<p>The ducted models still generally have the same control problems, previously mentioned. If you read my introduction to the
+<a href="https://mhoush.com/posts/coil-bypass-overview/">coil-bypass-system</a>, you have a basic understanding that even most traditional systems /
+designers do not focus on the proper air-changes in a structure to maintain proper IAQ levels.</p>
+<p>You can’t easily pair mini-splits with larger fan-coils because they are “communicating” style systems.</p>
+<h2>Conclusion</h2>
+<p>Don’t get me wrong, there are applications that are well suited for mini-splits. These are often applications like sun-rooms, garages, small
+server-rooms / network storage rooms, and many others. But in my opinion these are not at all my favorite and are generally really far down
+my list of options that I want to recommend to my clients.</p>
+<p>As an industry, I feel we need to step back and refocus on the pillars of IAQ. Filtration, fresh-air, and humidity control. The
+manufacturers / government should put less emphasis on chasing efficiency just to shoot ourselves in the foot and loose the qualities that
+make traditional / unitary style systems cover more if not all of the 3 pillars of proper IAQ.</p>
+<p>There’s plenty that I did not cover and I’m sure I missed some things, but just needed to rant for a few minutes… Thank you for making it
+to the end!</p>
