Water Chiller Refrigeration System

The refrigeration circuit is made up of four components.

Water chiller refrigeration system.

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

Water cooled chillers are more efficient because they condense depending on the ambient temperature bulb temperature which is lower than the ambient dry bulb temperature the lower a chiller condenses the more efficient it is. A chiller is a machine that removes heat from a liquid via a vapor compression adsorption refrigeration or absorption refrigeration cycles. In industrial and commercial refrigeration systems the heat is usually rejected to water. Industrial water or glycol chiller systems contain two main circuits.

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 fluid circuit is typically comprised. The refrigeration circuit removes heat from the process fluid. This liquid can then be circulated through a heat exchanger to cool equipment or another process stream such as air or process water.

Water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers. From the chilled water into the recirculating water. Refrigerant circulates through an evaporator compressor condenser and expansion device of a chiller.
