What is a Desert Air Cooler?

Desert air coolers can be defined as air coolers designed to keep the entire room cool, not just the bed it serves. They give the best results when placed outside the window, but work in-house to ensure they are placed at doors, or windows where they can extract outside air and don’t depend on the air inside a closed room. 

The cooling performance of desert air coolers depends on many factors, the main two being their place of installation, as explained above, and the climatic conditions under which they are operated. Desert air coolers are designed to give the best performance in dry hot summers with minimum humidity. Their efficiency decreases with rising humidity, 50% being a deciding humidity mark.

How does a Desert Cooler work?

Desert air coolers work on the principle of evaporating the cool water inside the reservoir and circulating it into the room to make the room cool. Evaporation is better when the air is hot and dry, giving higher cooling efficiency. Because of the enhanced evaporation, these air coolers are also called “Evaporative coolers.

Hot air from the environment is pulled by the fan. As it passes through the side panels containing cooling pads, hot air comes in contact with the water on the cooling pad. The water, for its contact with hot air, evaporates into cold vapours. These cold vapours are pulled by the fan and circulated into the room making it cool.

Why is it called a Desert Cooler?

The term “Desert” is symbolic of the Desert air coolers. It symbolises the effectiveness of desert air coolers in hot climatic conditions that we see in desert lands. The desert summers are hot and dry, and the wind breezes without obstructions. Desert air coolers are designed to meet the cooling needs of these conditions.

On the other hand, on hot but humid days, desert coolers are less effective as the air on the cooling pads doesn’t evaporate for outside humidity.
