Evaporative CoolingWhat is it? Also called “swamp cooling” evaporative cooling can be as simple as a wet cloth hung in a window; as air passes through some of its heat is used up in evaporating water from the cloth, and cooler air enters the structure.
How does it work? Evaporative cooling uses water to absorb heat from the air. In evaporative coolers, fresh air is brought in from outside a building and is passed through a specially designed media pad that is soaked with water. The water in the pad evaporates as hot air passes through it, cooling the air as well as trapping small particles and allowing clean, fresh air into a space.
What are the benefits? Evaporative cooling offers multiple benefits. It cools air, it does so much more efficiently than an air conditioner, and it also helps clean the air. Not only is evaporative cooling efficient, it’s easy on the planet, using no CFCs.
Why does Exup use it? Evaporative coolers can be a low cost, long lasting, highly efficient asset to passive solar design. Initial costs, operating costs and maintenance costs are much lower than other active cooling technologies, and evaporative coolers are much more efficient than air conditioners.
