Understanding Cooling Towers: Types, Functions, and Industrial Applications

COOLING TOWER :–

A cooling tower is a heat rejection device that cools water by evaporating a small portion of it, transferring heat to the atmosphere and then recirculating the cooled water

Functioning of Cooling Tower

  • Hot water from a heat exchanger or other source is pumped into the top of the tower and sprayed or distributed over a large surface area. 
  • Air is drawn or forced through the fill, coming into contact with the water. 
  •  As the water flows over the fill a portion of it evaporates, absorbing heat from the remaining water and cooling it. 
  • The cooled water collects at the bottom of the tower and is then recirculated back to the system for further use.
