Chiller - Wikipedia

A chiller is a machine that removes heat from a liquid via a vapor-compression, Adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater .
