A Chiller is a mechanical refrigeration device that cools a fluid, usually water. Industrial chillers are used wherever there is a need for cooling a fluid such as in a chemical process or plastic molding application. Chillers remove heat from a place where it is not needed. A chiller produces cold water by the transfer of heat from the entering water through the use of a refrigerant in the evaporator heat exchanger. An industrial chiller would, for example, chill 75˚F entering water down to 50˚F. The refrigerant would then carry the heat to the condenser for it to be transferred to the environment via an air-cooled coil or water–cooled heat exchanger.
A chiller consists of several major components: a compressor, an evaporator heat exchanger, a condenser heat exchanger, an expansion valve, and some piping and controls. The condenser can be either air-cooled (called an Air cooled chiller) with a coil or coils and a fan or fans, or water- cooled (called a Water cooled chiller) using a shell and tube heat exchanger cooled by a cooling tower.
