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.
The cooling tower moves heat from the water to the exhausting air thru evaporation. How Cooling Towers Work. There are a few kinds of cooling towers, but most work using evaporation and are very energy efficient. Heat is removed from the water circulating in the system by evaporating a small portion of it. Cooling towers can also work in a similar manner with the condensers of heat pumps.
