A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. 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 efficiency, recovered for heating purposes.[citation needed] Chillers may use hermetic scroll, or semi hermetic screw, or centrifugal compressors. They are often air or water cooled. If water cooled, the chiller is often cooled by a induced or forced draft cooling tower. Absorption chillers also exist. These require a heat source to function.  
Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional facilities. Water chillers can be water-cooled, air-cooled, or evaporatively cooled. Water-cooled systems can provide efficiency and environmental impact advantages over air-cooled systems. 
In this video we look at chiller types and refrigerant compressor cooling technology within HVAC commercial refrigeration and provide an overview guide on when and where each chiller type is used. This covers air cooled chillers and water cooled chillers, centrifugal compressors, turbocor compressors, screw compressors, scroll compressors, reciprocating compressors, absorption chillers. We look at both vapor compression and vapor absorption chillers. How chillers work and the basic working principle of each.
