Types of Water Chillers
Water chillers are used in a variety of air conditioning and process cooling
applications. They cool water that is subsequently transported by pumps
and pipes. The water passes through the tubes of coils to cool air in an air
conditioning system, or it can provide cooling for a manufacturing or industrial
process. Systems that employ water chillers are commonly called chilled-
water systems.
When designing a chilled-water system, one of the first issues that must be
addressed is to determine which type of water chiller to use. This period
discusses the primary differences in chiller types.
The refrigeration cycle is a key differentiating characteristic between chiller
types. The vapor-compression and absorption refrigeration cycles are the two
most common cycles used in commercial air conditioning.
