For a larger working area, a substantial HVAC system is needed. Chiller is a machine that removes heat from fluids (liquid or gas). As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Compressor is the heart of any chiller plant that comes in various types and procures according to the type of use or area to be cooled. Chilled water is used to cool and dehumidify air in mid and large size commercial, industrial, and institutional facilities. Water chillers can be water-cooled, air-cooled, or evaporative cooled.
Components of a chiller:
· Receiver
· Expansion device
· Surge tank
· Heat exchanger (evaporator)
· Compressor
· Condenser
