An HVAC cooling tower is used for disposing or rejecting heat from chillers. Air cooled chillers are less effecient than water cooled chillers due to rejection of heat from tower water near wet-bulb temperatures.
A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water's temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.Water, which has been heated by an industrial process or in an air-conditioning condenser, is pumped to the cooling tower through pipes.s this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.
