A chiller air handler is a device used to cool air in a building or other enclosed space. It is typically used in industrial and commercial settings, such as factories, warehouses, and office buildings. The chiller air handler works by drawing in warm air from the outside and cooling it down before sending it back into the space. The air handler is typically made up of several components, including a compressor, evaporator, condenser, and expansion valve. The compressor compresses the refrigerant, which is then circulated through the evaporator and condenser. The evaporator absorbs the heat from the air, and the condenser releases the heat to the outside. The expansion valve then regulates the pressure of the refrigerant, allowing it to be released back into the space as cooled air. The chiller air handler is an efficient and cost-effective way to cool large areas, and is used in many different types of applications.
