Industrial Air Coolers

Evaporating cooling is a physical phenomenon in which evaporation of a liquid, typically into surrounding air, cools an object or a liquid in contact with it. Latent heat describes the amount of heat that is needed to evaporative the liquid; this heat comes from the liquid itself and the surrounding gas and surfaces. When considering water evaporating into air, the wet-bulb temperature, as compared to the air’s dry-bulb temperature, is a measure of the potential for evaporating cooling. The greater the difference between the two temperature, the better the evaporative cooling effects. When the temperature are the same, no net evaporation of water in air occurs, thus there is no cooling effect.
