How does HVAC Chillers Works?

HVAC chillers are the main component of HVAC systems that provide cooling for industrial, commercial, and residential applications. Growing preference for district cooling systems in industries and high-rise buildings are the major driver for the HVAC chillers market. Increasing population and urbanization, rising temperature, and pollution across the globe due to the uncontrollable greenhouse and other toxic gas emissions result in the rising installation of HVAC systems, which fuels the HVAC chillers market growth.

Growing replacement of traditional air-cooling systems, due to its benefits such as high efficiency, low maintenance, and less operational costs. This, in turn, booming the growth for the HVAC chillers market during the forecast period. Further, the emerging need for comfortable and safe indoor environment systems is likely to flourish the HVAC chillers market. The growing construction of industrial and commercial buildings such as hospitals, educational institutions, hotels, shopping malls, etc. are expected to provide ample growth opportunities for the HVAC chillers market in the coming years.

Process chillers contain a chemical compound, called a refrigerant. There are many types of refrigerant and applications depending on the temperatures required but they all work on the basic principle of compression and phase-change of the refrigerant from a liquid to a gas and back to a liquid. This process of heating and cooling the refrigerant and changing it from a gas to a liquid and back again is the refrigeration cycle.

The refrigeration cycle starts with a low-pressure liquid/gas mix entering the evaporator. In the evaporator, heat from the process water or water/glycol solution boils the refrigerant, which changes it from a low-pressure liquid to a low-pressure gas. The low-pressure gas enters the compressor where it is compressed to high-pressure gas. The high-pressure gas enters the condenser where ambient air or condenser water removes heat to cool it to a high-pressure liquid. The high-pressure liquid travels to the expansion valve, which controls how much liquid refrigerant enters the evaporator, thereby beginning the refrigeration cycle again.
