Evaporative Cooling Towers
Evaporative Cooling Towers 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. Its works by employing water's large vaporization and The temperature of dry air can
be dropped significantly through the phase transition of liquid water to water vapor (evaporation), which
can cool air using much less energy than refrigeration.
An Evaporative Cooling is extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. Evaporative cooling requires a water source, and must continually consume water to operate. The superheated water was then sprayed through a nozzle into an open tube and releasing its heat. The tubes could be placed under the skin of the aircraft, resulting in a zero-drag cooling system. 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. Evaporative cooling requires an water source as an evaporate, and is only efficient when the relative humidity is low, restricting its effective use to dry climates. Evaporative cooling also raises the internal level significantly, which can cause problems such as lumpy table salt, swelling and warping of wood paneling, doors and trim; pianos going out of tune or suffering internal rusting, etc.
Evaporative cooling is a physical phenomenon in evaporation of a liquid, typically into surrounding air, cools an object and liquid in contact with it. The amount of heat that is needed to evaporate the liquid, is drawn from the air. The wet-bulb temperature which takes both temperature and As compared to the actual air temperature , is a measure of the potential for evaporative cooling. The greater the difference between the two temperatures, the greater the evaporative cooling effect. When the temperatures are the same, no net evaporation of water in air occurs, thus there is no cooling effect. The wet-bulb temperature is essentially the lowest temperature which can be attained by evaporative cooling tower.
