Introduction
Water chillers are used in a variety of air conditioning and process cooling
applications. They are used to make cold water that can be transported
throughout a facility using pumps and pipes. This cold water can be passed
through the tubes of coils to cool the air in an air conditioning application, or it
can provide cooling for a manufacturing or industrial process.
Systems that employ water chillers are commonly called chilled water
systems.
There are several types of water chillers. They differ from each other based on
the refrigeration cycle or the type of compressor they use.
Absorption water chillers make use of the absorption refrigeration cycle and do
not have a mechanical compressor involved in the refrigeration cycle.
