Water Cooled Chillers

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.

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.
