Evaporative cooling is the process of dripping water over pads and blowing air across them into the structure. Over the years the units have been designed better but the process is still the same. They bring in 100% outside air and the windows of the structure must remain partially open to replace the cooled air with new. As humidity levels rise the efficiency goes down and the body feels no relief from the heat. swamp cooler

The transition from liquid water to water vapor is evaporation, using this process to cool offers several benefits. A structure can be cooled with less energy and there is no need for duct work. Each room in the building or home can have a window slightly open and the air flow will reach the desired area. Evaporative cooling only works in dry desert climates and uses a very precious comodity in dry areas...water. Using refrigeration for cooling is significantly more comfortable and saves water.
