Skyscraper rooftop mechanical7/11/2023 ![]() The evaporative cooler was the subject of numerous US patents in the 20th century many of these, starting in 1906, suggested or assumed the use of excelsior (wood wool) pads as the elements to bring a large volume of water in contact with moving air to allow evaporation to occur. Modern Iranians have widely adopted powered evaporative coolers ( coolere âbi). They caught the wind, passed it over subterranean water in a qanat and discharged the cooled air into the building. Passive evaporative cooling strategies can offer the same benefits as mechanical evaporative cooling systems without the complexity of equipment and ductwork.Īn earlier form of evaporative cooling, the windcatcher, was first used in ancient Egypt and Persia thousands of years ago in the form of wind shafts on the roof. In climates not considered arid, indirect evaporative cooling can still take advantage of the evaporative cooling process without increasing humidity. In arid climates, evaporative cooling can reduce energy consumption and total equipment for conditioning as an alternative to compressor-based cooling. The cooling potential for evaporative cooling is dependent on the wet-bulb depression, the difference between dry-bulb temperature and wet-bulb temperature (see relative humidity). ![]() In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. This can cool air using much less energy than refrigeration. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). Evaporative cooling exploits the fact that water will absorb a relatively large amount of heat in order to evaporate (that is, it has a large enthalpy of vaporization). Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Porous pottery and coarse cloth maximize the area for evaporation.Īn evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water.
