Many industrial processes utilize a process fluid to cool the equipment by moving heat away from the operation. An industrial chiller is a type of equipment used to accomplish this. The cooling system is designed to remove heat from the process fluid, transfer the heat to another medium such as ambient air or water, and return cool fluid to the process to begin the cycle again.
Process chillers are designed to be air-cooled or water-cooled units. Either type uses a refrigerant at a low temperature to absorb heat from process fluid in the evaporator. Once the refrigerant absorbs the heat, this higher temperature fluid passes to the condenser, where it rejects that absorbed heat. The condenser transfers the heat to the ambient air or to a water source such as a cooling tower.
