The adiabatic cooling effect is a natural phenomenon caused by the cooling of humid air due to an increase in humidity. This effect occurs when moist air is cooled quickly, for example by a spray.

Cooling is adiabatic, which means that no external energy source is required. The reason for this is that moisture is present in the air in the form of water vapor. When the air cools rapidly, the water vapor loses energy and this energy is used to lower the air temperature.

By using spray mist devices that spray fine water mist into the air, the adiabatic cooling effect can be used to lower the air temperature indoors, factory floors and even outdoors. These devices increase the humidity of the air, thereby lowering the air temperature.

One advantage of adiabatic cooling is cost efficiency, since no external energy source is required.
