Air & Water Cooled Chiller

Water Cooled & 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.


How Water Cooled & Air Cooled Chillers Work

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.

Components of a Water Cooled & Air Cooled Chiller

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.

Evaporative condenser

Evaporative condensers improve the heat rejection process by using the cooling effect of evaporation. Water is sprayed over the condensing coil from above while air is simultaneously blown up through the coil from below to naturally lower the condensing temperature.

Expansion valve

A thermal expansion valve is a component in refrigeration and air conditioning systems that control the amount of refrigerant flow into the evaporator thereby controlling the superheat at the outlet of the evaporator.

Air compressor

An air compressor is a device that converts power into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure.
