What is Evaporative Cooling?
As the name suggests, evaporative cooling is a type of cooling system. It employs the basic principle of evaporation to cool air. An evaporative cooler has a unit mounted on a roof that takes in hot and dry fresh air from outside. As the air draws in, it passes through soaking-wet cooling pads that evaporate heat and reduce the air temperature. The cooled air then circulates through the home via ductwork and vents. When in operation, it is important to leave a window or door open. This is so the hot air in a room can move out and cool air from the vents can move in.
Evaporative air conditioning suits a variety of homes and works well in most climates. However, it is not typically recommended for areas with high humidity.
