How Cooling Tower Systems Work

How Cooling Tower Systems Work

Cooling towers are recirculating water systems used to remove heat from building air conditioning equipment and industrial processes. They require specialized maintenance to ensure safe, efficient, and reliable operation, including an effective water treatment program.  By understanding how cooling tower systems function, facility owners and operators can operate and maintain their systems more effectively.

Cooling tower systems work by using water to extract waste heat from a system and ejecting it into the atmosphere primarily through evaporation.  The three key components of a cooling system are the cooling tower, recirculating pump, and heat exchanger. Water first passes through a heat exchanger where it absorbs heat. The water is then distributed over the top of the cooling tower where air travels past the warm water causing a portion of the water to evaporate. The heat is transferred from the water stream to the air stream, raising the air’s temperature and its relative humidity to 100%.  This warm air is then discharged to the atmosphere, resulting in a cool water stream. The cooled water from the basin is then pumped back through a heat exchanger and the cycle repeats.
