Water Chiller Refrigeration System

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.

Water chiller refrigeration system.

A chiller is a machine that removes heat from a liquid via a vapor compression adsorption refrigeration or absorption refrigeration cycles. As a necessary by product refrigeration creates waste heat that must be exhausted to ambience or for greater. 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. From the chilled water into the recirculating water.

Refrigerant circulates through an evaporator compressor condenser and expansion device of a chiller. A chiller uses a vapor compression mechanical refrigeration system that connects to the process water system through a device called an evaporator. In most process cooling applications a pumping system circulates cool water or a water glycol solution from the chiller to the process. 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. A refrigeration circuit and a fluid circuit. The refrigeration circuit is made up of four components. The refrigeration circuit removes heat from the process fluid.

This cool fluid removes heat from the process and the warm fluid returns to the chiller. The fluid circuit is typically comprised. The compressor the condenser the expansion valve and the evaporator.
