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.

Figure 3

Although water chillers come in many sizes and types, they all produce cooling using the same basic principles of heat transfer and change-of-phase of the refrigerant. This is accomplished by the chiller refrigeration cycle. They differ from each other based on the refrigeration cycle and the type of refrigerant fluid used.
