Air and water chillers are refrigeration systems that cool fluids or dehumidify air. They are primarily used in both commercial and industrial facilities. The chilled water can be used for space cooling or industrial processes. Air-cooled chillers include an evaporator, condenser, compressor, and an expansion valve. These differ from water-cooled chillers in that they use environment air instead of water and a cooling tower to cool the condenser.
Using a high efficiency chiller will yield a 30 percent average energy savings compared to a normal chiller. An average 100-ton chiller has a lifetime energy cost of $219,000. Equivalent energy efficient models, by comparison, boast a lifetime energy cost of approximately $172,000 to $145,000.
