Cooling Principle

Cooling Principle


An evaporative cooler(also known as desert cooler,wet air cooler and swamp cooler) is used to chill air by evaporating water.Evaporative cooling devices are different from the typical systems of air conditioning that adopt vapor-compression or absorption refrigerant circulations.The theory of evaporative coolers is to utilize the high heat content of water when evaporated.During the transitional stage from fluid water to water steam(evaporation),the dry air can be cooled magnificently,thus saving much energy compared to refrigeration.In the exceedingly arid climates,evaporative cooling of air shows an additional advantage that it renders the air moister to give to building residents the best comfort possible.

The latent capacity of evaporative cooling depends on the wet bulb depression,the temperature diversity between the dry bulb and the wet bulb.Under dry climate conditions,evaporative cooling can consume less energy and the entire air conditioning devices can be a replacement of compressor-based chilling.Under climatic conditions not deemed as drought,indirect evaporative cooling is still able to take use of the evaporative cooling course with no dampness raised.Passive evaporative cooling tactics work as well as mechanical evaporative cooling systems with no complication of devices and pipework.

The performance of evaporative rate of humidity.As it is seen is 50% and temperature is about 23℃.That makes JOYHI classical air conditioner.They are manufactured in typical portable.Industrial coolers are used in factories,stores,sport halls and so on.Portable models are designed do not need installation.Evaporative coolers are more ecconomical than air coolers.
