Water Chiller Refrigeration System

Water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers.

Water chiller refrigeration system. The refrigeration circuit is made up of four components. The compressor the condenser the expansion valve and the evaporator. Once through cooling may be used but water costs and environmental restrictions dictate recirculating system utilizing cooling towers to reject the heat into the atmosphere. The refrigeration circuit removes heat from the process fluid.

In most process cooling applications a pumping system circulates cool water or a water glycol solution from the chiller to the process. As a necessary by product refrigeration creates waste heat that must be exhausted to ambience or for greater. This cool fluid removes heat from the process and the warm fluid returns to the chiller. A chiller uses a vapor compression mechanical refrigeration system that connects to the process water system through a device called an evaporator.

This liquid can then be circulated through a heat exchanger to cool equipment or another process stream such as air or process water. In industrial and commercial refrigeration systems the heat is usually rejected to water. The fluid circuit is typically comprised. A chiller is a machine that removes heat from a liquid via a vapor compression adsorption refrigeration or absorption refrigeration cycles.

Refrigerant circulates through an evaporator compressor condenser and expansion device of a chiller. Industrial water or glycol chiller systems contain two main circuits. The process water is the means by which heat transfers from the process to the chiller.
