What is Evaporative Cooling?

The most efficient means of cooling in nature is water evaporation. When you stay at the seaside with a wet body on a hot day, with the wind blowing, you will feel very cool. An evaporative air cooler is just working on the principle of heat absorption by moisture evaporation.

An evaporative air cooler (also known as evaporative air conditioner, swamp cooler, or desert cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use compressors. An evaporative air cooler only using water evaporation to absorb the heat to make the air cool. During this process, no freon, no harmful gas will be released to the environment.

The cooling potential for evaporative cooling depends on the wet-bulb temperature and the dry-bulb temperature. It is very suitable for dry and hot areas. The temperature can be reduced by 5-13 degrees.
