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A cooling tower is a heat exchanger, inside of which heat is withdrawn from the water by contact between the water and the air. The heat transfer occurs through the heat exchange between air and water and through the evaporation of a small part of the water that needs to be cooled. cooling tower is a heat exchanger, inside of which heat is withdrawn from the water by contact between the water and the air.
