What is the internal structure of an evaporative cooler like?
Hot, outside air enters the evaporative cooler and passes over water-saturated pads. The water evaporates into the air and this energy is used to remove heat from the air. From there, the cooler air (15-40 degrees lower) is directed into the home, pushing the warmer air out through windows. Since this process also humidifies the air, evaporative coolers are best used in areas with low, summertime humidity.
