1. What is the compressor types?Commonly utilize scroll, screw, or centrifugal compressors in vapor-compression systems
2. What is the condensing methods?Can be air-cooled, water-cooled (often with cooling towers), or evaporatively cooled
3. How does a chiller cool air in a big building?It uses a cycle that takes a refrigerant, lets it absorb heat, compresses it, releases the heat outside, and then cools the liquid that runs through the building.
4. Why are chillers important for hospitals and schools?They keep the rooms at a comfortable temperature and steady humidity so people can work, learn, and stay healthy.

Thermodynamic Cycles: Processes involving heat and work, used by chillers to move thermal energy.
Refrigerant: A working fluid that undergoes phase changes to absorb and release heat.
Heat Exchanger: A device designed to efficiently transfer thermal energy between two or more fluids.
Global Warming Potential (GWP): A measure of how much heat a greenhouse gas traps in the atmosphere compared to carbon dioxide.
