Cooling towers are being widely used in the industries for the removal of unwanted heat from one’s factories. After removal of the unwanted heat, the machines work more efficiently because of the good working environment.
Cooling is provided via evaporative cooling towers based on a planned dew point temperature. Evaporative cooling towers generally chill water to around 85° F, although they may cool to as low as 65° F. They are the most cost-effective method of cooling huge volumes of water.
The method of eliminating hot air from a medium by evaporating water is known as evaporative cooling.
Latent heat is required to raise the temperature that water stores. The surface temperature drops as heat transfers from the surface to the water.
