Water Chiller Refrigeration System

This cool fluid removes heat from the process and the warm fluid returns to the chiller.

Water chiller refrigeration system.

This liquid can then be circulated through a heat exchanger to cool equipment or another process stream such as air or process water. The refrigeration circuit is made up of four components. The process water is the means by which heat transfers from the process to the chiller. A refrigeration circuit and a fluid circuit.

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. 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.

The refrigeration circuit removes heat from the process fluid. 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. In most process cooling applications a pumping system circulates cool water or a water glycol solution from the chiller to the process. A chiller is a machine that removes heat from a liquid via a vapor compression adsorption refrigeration or absorption refrigeration cycles.

The fluid circuit is typically comprised. Water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers. In industrial and commercial refrigeration systems the heat is usually rejected to water.
