How Swamp Coolers Work. Swamp Coolers (also known as Evaporative Cooler, Desert Cooler, and Wet Air Coolers) use the principles of evaporative cooling to cool the air around you, it’s a simple process that cools the air through the evaporation of water. Swamp Coolers work different than typical air conditioners, evaporative coolers take advantage of the natural process of water absorbing heat in order to evaporate and then turns that heat into cool air. Swamp Coolers also use much less energy than conventional air conditioners and they are environmentally friendly.
If you’ve ever tested which way the wind blows by holding a wet finger in the air, you’ve used evaporative cooling, it’s the same principle that makes you colder when you get out of the shower or the pool. It is one of the oldest and simplest forms of cooling the air. Known in the U.S. as Swamp Coolers, they can trace their lineage to ancient Egypt. They’re cheap, efficient and good for the environment, a Swamp Cooler can cool the air using much less energy than refrigeration. In extremely dry climates, Swamp Coolers have the added benefit of conditioning the air with more moisture for the comfort of building occupants. Evaporative Cooling works best in hot, dry climates.
