Evaporative Cooling Systems Building America Solution Center

Evaporative Cooling Systems Building America Solution Center Install an evaporative cooler to provide efficient cooling in a dry climate: determine if evaporative cooling is an appropriate option for your location based on cooling design wet bulb temperatures. determine the approximate air changes per hour (ach) needed to adequately cool your home based on local climate and manufacturer guidelines. Evaporative cooling (a.k.a., "swamp coolers") is a technology that takes advantage of water evaporation to cool incoming air. energy is required to change water from a liquid to a vapor (i.e., the heat of vaporization), and in doing so, the sensible air temperature of the air is reduced. the amount of cooling provided is driven by the "dryness.

Evaporative Cooling Systems Building America Solution Center Evaporative cooling has physical limits, however: the more hot and humid the environment is, the less effective evaporative cooling can be. evaporative coolers. evaporative coolers are a practical and effective cooling solution in very dry climates (figures 36 and 37). they use a fraction of the energy of typical air conditioning units. Direct evaporative cooling systems put the process fluid, typically water, into direct contact with air. water flows through fill as a fan draws air across it, facilitating the transfer of heat from the warm water to the cooler air. this is the system used in open air cooling towers, such as evapco’s factory assembled cooling towers. Evaporative cooling is based on the adiabatic process of evaporation. as air passes over a wetted surface, it begins to cool. this cooling effect is a result of water from the wetted surface evaporating into the passing airstream. the process is fully adiabatic, resulting in a net zero exchange of energy. sensible heat removed from the passing. 303 447 0078. fax: 303.786.8054. swenergy.org. this report on new emerging evaporative cooling options is one a series of technical briefs being prepared by the southwest energy efficiency project (sweep) in support of the u.s. department of energy’s building america program.

Direct evaporative cooling begins by saturating air with water, typically through a medium such as wet pads, or through a direct or indirect solution. this moistened air, at a lower temperature due to the energy taken to evaporate the water, is then circulated through the industrial space, lowering the overall temperature.
