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.
Water chiller refrigeration system.
The fluid circuit is typically comprised.
The process water is the means by which heat transfers from the process to the chiller.
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.
Industrial water or glycol chiller systems contain two main circuits.
This liquid can then be circulated through a heat exchanger to cool equipment or another process stream such as air or process water.
A refrigeration circuit and a fluid circuit.
The compressor the condenser the expansion valve and the evaporator.
A chiller uses a vapor compression mechanical refrigeration system that connects to the process water system through a device called an evaporator.
Refrigerant circulates through an evaporator compressor condenser and expansion device of a chiller.
The refrigeration circuit is made up of four components.
This cool fluid removes heat from the process and the warm fluid returns to the chiller.
A chiller is a machine that removes heat from a liquid via a vapor compression adsorption refrigeration or absorption refrigeration cycles.
Water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers.
The refrigeration circuit removes heat from the process fluid.
