Water Cooled Chillers

Water Cooled Chillers & Air Cooled Chillers

Water cooled chillers and air cooled chillers are refrigeration systems used to cool fluids or dehumidify air in both commercial and industrial facilities.  Chilled water has a variety of applications from space cooling to process uses.  For more information regarding industrial chillers, please click here.

The components of water cooled chillers and air cooled chillers are very similar.  Each product contains an evaporator, condenser, compressor, and an expansion valve.  The primary difference is whether air or water is used to provide the condenser cooling. 

The cycle begins in the evaporator where a liquid refrigerant flows over the evaporator tube bundle and evaporates, absorbing heat from the chilled water circulating through the bundle.  The refrigerant vapor is drawn out of the evaporator by the compressor.  The compressor then “pumps” the refrigerant vapor to the condenser raising its pressure and temperature.  The refrigerant condenses on or in the condenser tubes, giving up its heat to the cooling water (or air).  The high pressure liquid refrigerant from the condenser then passes through the expansion device that reduces the refrigerant pressure and temperature as it enters the evaporator.  The refrigerant again flows over the chilled water coils absorbing more heat and completing the cycle.

Each chiller has basic maintenance requirements to ensure it functions at optimal levels.  To see a chart of recommended maintenance actions, please click here.  Maintenance packages are available from Cooling Technology, Inc.  Please contact your sales rep for further information.
Large industrial chillers are commonly located in mechanical equipment rooms within the building close to the process in which they are cooling.  Some industrial chillers may be located directly beside the process, depending on the size of the chiller and compressor.  Some may even be placed completely outdoors.  A Cooling Technology, Inc. representative will be happy to work with you to determine which will best fit your requirements.
