10 Facts About Evaporative cooler

An evaporative cooler is a device that cools air through the evaporation of water.

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 pads as the elements to bring a large volume of water in contact with moving air to allow evaporation to occur.

Evaporative cooler cooling is the conversion of liquid water into vapor using the thermal energy in the air, resulting in a lower air temperature.

Evaporative cooler 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 cooler cooling is most effective when the relative humidity is on the low side, limiting its popularity to dry climates.

Evaporative cooler cooling is especially well suited for climates where the air is hot and humidity is low.

Evaporative cooler cooling is the last cooling step in order to reach the ultra-low temperatures required for Bose–Einstein condensation .

Mechanical direct evaporative cooler unit uses a fan to draw air through a wetted membrane, or pad, which provides a large surface area for the evaporation of water into the air.

Indirect Evaporative cooler manufacturer uses the Maisotsenko cycle, named after inventor and Professor Dr Valeriy Maisotsenko, employs an iterative heat exchanger made of a thin recyclable membrane that can reduce the temperature of product air to below the wet-bulb temperature, and can approach the dew point.

Traditionally, evaporative cooler pads consist of excelsior inside a containment net, but more modern materials, such as some plastics and melamine paper, are entering use as cooler-pad media.
