Evaporative Cooling

 

An evaporative air conditioner uses evaporation to help cool the air. Based on the principles of evaporation, hot and dry outside air is pumped through water-soaked cooling pads.

As the air is pushed through the cooling pads, the water evaporates and the heat in the air is absorbed, which lowers the air temperature.

A fan then pushes the cool air throughout a house via a network of ducts.
