How Air Cooled Chillers Work
Air cooled chillers operate by using air as the cooling medium to remove heat from the refrigerant. These systems consist of a refrigeration circuit that includes a compressor, condenser, expansion valve, and evaporator. The compressor compresses the refrigerant gas, raising its temperature and pressure before sending it to the condenser. In the condenser, the hot refrigerant gas releases heat to the ambient air as a fan blows outside air over the coils, causing the gas to condense into a liquid state.
Once the refrigerant has shed its heat and turned into a liquid, it passes through the expansion valve and into the evaporator. Inside the evaporator, the liquid refrigerant evaporates as it absorbs heat from the process water circulating through the chiller. The now-gaseous refrigerant is then drawn back to the compressor to start the cycle over again. Air cooled chillers are ideal for locations where water availability or quality is limited, offering a reliable and cost-effective cooling solution for various applications.
