+
+# Define Chillers
+
+Chillers are mechanical devices used in heating, ventilation, and air conditioning (HVAC) systems
+to remove heat from a liquid via a vapor-compression or absorption refrigeration cycle.
+
+---
+
+# Applications in HVAC
+
+1. **Commercial Buildings:**
+    - Chillers are commonly found in shopping malls, office buildings, and hospitals, where they are used to cool large open spaces and maintain comfortable indoor temperatures.
+1. **Industrial Processes:**
+    - Chillers are used to cool machinery and products, particularly in manufacturing processes that generate substantial amounts of heat.
+1. **Air Conditioning Systems:**
+    - In large HVAC systems, chillers provide chilled water, which is then utilized by air handling units (AHUs) or fan coil units to cool air before it is distributed throughout the building.
+1. **District Cooling:**
+    - Chillers are sometimes used in district cooling systems, where a central chiller plant provides chilled water to multiple buildings in a defined area.
+
+^ Note how residential does not appear on the list.

+
+# What do we do?
+
+- Provide healthy, safe, and comfortable environment.
+- We move heat from one place to another, generally through refrigerant and air circulation...
+- Water _IS_ a refrigerant (R-718).
+
+^ Second one is important to remember for later in the talk.

These systems utilized hot air generated by a furnace that circulated through spaces beneath the floors and inside walls. The concept evolved over the centuries, with significant advancements during the Industrial Revolution in the 19th century. The introduction of cast iron radiators and steam heating systems provided more efficient heating solutions, which led to the broader adoption of hydronic technologies in residential and commercial buildings.\n\nIn the 20th century, hydronic systems further advanced with the development of modern boiler technology and the introduction of pumps for circulating water. The focus shifted toward energy efficiency and improved indoor comfort, leading to the emergence of innovative products like micro-boilers, zone control systems, and smart thermostats. Today, hydronic heating and cooling systems are recognized for their efficiency, environmental benefits, and ability to provide consistent temperature control, making them a popular choice for contemporary HVAC applications.",
