An evaporative cooler also swamp cooler, desert cooler and wet air cooler is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor compression or absorption refrigeration cycles. Evaporative cooling works by exploiting waters large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor evaporation. This can cool air using much less energy than refrigeration. 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. The cooling potential for evaporative cooling is dependent on the wet bulb depression, the difference between dry bulb temperature and wet bulb temperature. In arid climates, evaporative cooling can reduce energy consumption and total equipment for conditioning as an alternative to compressor based cooling. In climates not considered arid, indirect evaporative cooling can still take advantage of the evaporative cooling process without increasing humidity. Passive evaporative cooling strategies offer the same benefits of mechanical evaporative cooling systems without the complexity of equipment and ductwork. Overviewedit. Schematic diagram of an ancient Iranian windcatcher and qanat, used for evaporative cooling of buildings. An earlier form of evaporative cooling, the windcatcher, was used in ancient Egypt and Persia thousands of years ago in the form of wind shafts on the roof. They caught the wind, passed it over subterranean water in a qanat and discharged the cooled air into the building. Modern Iranians have widely adopted powered evaporative coolers coolere bi. The evaporative cooler was the subject of numerous US patents in the 2. A typical design, as shown in a 1. This design and this material remain dominant in evaporative coolers in the American Southwest, where they are also used to increase humidity. In the United States, the use of the term swamp cooler may be due to the odor of algae produced by early units. Externally mounted evaporative cooling devices car coolers were used in some automobiles to cool interior airoften as aftermarket accessories6until modern vapor compression air conditioning became widely available. Passive evaporative cooling techniques in buildings, such as evaporative cooling towers, have only been developed and studied in the last 3. In 1. 97. 4, William H. Goettl invented the Combination Refrigeration and Evaporative Cooling Air Conditioner in Arizona after noticing that evaporative cooling technology works better in arid climates rather than humidity but that a combination unit would be more effective. In 1. 98. 6, two researchers at the University of Arizona, Tucson, W. Cunningham and T. Thompson, constructed the first passive evaporative cooling tower in Tucson, AZ. This performance data from this experimental facility became the foundation of todays evaporative cooling tower design guidelines, developed by Baruch Givoni. Physical principleseditEvaporative 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. The energy needed to evaporate the water is taken from the air in the form of sensible heat, which affects the temperature of the air, and converted into latent heat, the energy present in the water vapor component of the air, whilst the air remains at a constant enthalpy value. This conversion of sensible heat to latent heat is known as an isenthalpic process because it occurs at a constant enthalpy value. Evaporative cooling therefore causes a drop in the temperature of air proportional to the sensible heat drop and an increase in humidity proportional to the latent heat gain. Evaporative cooling can be visualized using a psychrometric chart by finding the initial air condition and moving along a line of constant enthalpy toward a state of higher humidity. A simple example of natural evaporative cooling is perspiration, or sweat, secreted by the body, evaporation of which cools the body. The amount of heat transfer depends on the evaporation rate, however for each kilogram of water vaporized 2,2. J of energy about 8. BTU per pound of pure water, at 9. F 3. 5 C are transferred. The evaporation rate depends on the temperature and humidity of the air, which is why sweat accumulates more on humid days, as it does not evaporate fast enough. Vapor compression refrigeration uses evaporative cooling, but the evaporated vapor is within a sealed system, and is then compressed ready to evaporate again, using energy to do so. A simple evaporative coolers water is evaporated into the environment, and not recovered. In an interior space cooling unit, the evaporated water is introduced into the space along with the now cooled air in an evaporative tower the evaporated water is carried off in the airflow exhaust. Other types of phase change coolingeditA closely related process, sublimation cooling differs from evaporative cooling in that a phase transition from solid to vapor, rather than liquid to vapor, occurs. Sublimation cooling has been observed to operate on a planetary scale on the planetoid Pluto, where it has been called an anti greenhouse effect. Another application of a phase change to cooling is the self refrigerating beverage can. A separate compartment inside the can contains a desiccant and a liquid. Just before drinking, a tab is pulled so that the desiccant comes into contact with the liquid and dissolves. As it does so it absorbs an amount of heat energy called the latent heat of fusion. Evaporative cooling works with the phase change of liquid into vapor and the latent heat of vaporization, but the self cooling can uses a change from solid to liquid, and the latent heat of fusion to achieve the same result. ApplicationseditBefore the advent of refrigeration, evaporative cooling was used for millennia. A porous earthenware vessel would cool water by evaporation through its walls frescoes from about 2. BC show slaves fanning jars of water to cool rooms. A vessel could also be placed in a bowl of water, covered with a wet cloth dipping into the water, to keep milk or butter as fresh as possible. California ranch house with evaporative cooler box on roof ridgeline. Evaporative cooling is a common form of cooling buildings for thermal comfort since it is relatively cheap and requires less energy than other forms of cooling. Psychrometric chart example of Salt Lake City. The figure showing the Salt Lake City weather data represents the typical summer climate June to September. The colored lines illustrate the potential of direct and indirect evaporative cooling strategies to expand the comfort range in summer time. It is mainly explained by the combination of a higher air speed on one hand and elevated indoor humidity when the region permits the direct evaporative cooling strategy on the other hand. Evaporative cooling strategies that involve the humidification of the air should be implemented in dry condition where the increase in moisture content stays below recommendations for occupants comfort and indoor air quality. Passive cooling towers lack the control that traditional HVAC systems offer to occupants. However, the additional air movement provided into the space can improve occupant comfort. Evaporative cooling is most effective when the relative humidity is on the low side, limiting its popularity to dry climates. Evaporative cooling raises the internal humidity level significantly, which desert inhabitants may appreciate as the moist air re hydrates dry skin and sinuses.
