What is Evaporative Cooling?

An Evaporative Cooler uses evaporation technology to cool the air via a pump that circulates water from the reservoir onto a cooling pad, which becomes saturated. Air from outside of the cooler is drawn into the unit through the moistened pad. The air passes through the pad and is cooled by the evaporation process. Ensuring each cooling pad is continuously saturated is the key to effective evaporative cooling.  The system fans and motor must also be sized and designed to deliver the appropriate airflow for the preferred environment.

As the evaporation process takes place heat created by energy is lost from the air, decreasing the temperature. Water evaporation occurs when humidity is under 100% and the air begins to absorb water. The term “humidity” describes how much water is already in the air in comparison to the amount it can hold. Although the degree of absorption depends on the amount it is already holding, any given volume of air can hold a certain amount of water vapor. The air is saturated when it is at capacity and cannot hold any more water.
