Chiller

Definition

A heat pump dedicated to cooling that moves heat from a chilled water loop into a condenser water loop using a refrigerant cycle.

A chiller does not create cold, it relocates heat, lifting it from a low temperature where it causes problems to a higher temperature where it can be rejected. It produces a cold fluid that does the cooling work for the building rather than cooling the building directly. Its four components are the evaporator, compressor, condenser, and expansion valve.
