Evaporative coolers lower the temperature of air using the principle of evaporative cooling, unlike typical air conditioning systems which use vapor-compression refrigeration or absorption refrigerator. Evaporative cooling is the addition of water vapor into air, which causes a lowering of the temperature of the air.or direct evaporative cooling, the direct saturation efficiency, , measures in what extent the temperature of the air leaving the direct evaporative cooler is close to the wet-bulb temperature of the entering air.
Due to the evaporative process used by these swamp coolers, these cooling units are best used in hot, dry climates, including the Southwestern United States. In these climates, however, an evaporative cooler can be your most effective and efficient means of climate control. There are many different benefits of evaporative cooling, but to truly understand them, you have to compare evaporative coolers to more traditional air conditioners.
