The chiller in HVAC (Heating, Ventilation, and Air Conditioning) functions by cooling water or a liquid refrigerant and circulating it throughout a building to remove heat. The chiller's main components include the compressor, condenser, expansion valve, and evaporator. The cyclic process of a chiller is as follows: 1. Suction (Evaporation): The refrigerant absorbs heat from the environment in the evaporator, turning into gas. 2. Compression: The refrigerant is compressed by the compressor, increasing its temperature and pressure. 3. Condensation: The hot, high-pressure gas releases its heat to the condenser (usually water), cooling down and turning into a high-pressure liquid. 4. Expansion (Metering): The high-pressure liquid passes through the expansion valve, reducing its pressure and temperature, causing it to become a low-pressure liquid ready for evaporation.
