An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles.
The expansion valve partially vaporizes the refrigerant cooling it via evaporative cooling and the resulting vapor is cooled via expansive cooling. (This is a combination of Joule-Thomson cooling and work done by the expanding gas, both at the expense of the internal energy of the gas) The cold, low pressure liquid refrigerant will now absorb ...
A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed.
For indoor use, evaporative coolers work best in climates with humidity levels around or below 30 percent. Roughly speaking, that covers the western and southernmost states of the U.S.
A portable evaporative cooler (aka "swamp" cooler) does basically the same job as a window or portable AC unit, but at a fraction of the cost. ... Evaporative coolers work by forcing air through a ...
Since the cooling towers are based on the principles of evaporative cooling, the maximum cooling tower efficiency depends on the wet bulb temperature of the air. The wet-bulb temperature is a type of temperature measurement that reflects the physical properties of a system with a mixture of a gas and a vapor, usually air and water vapor
Evaporative coolers, also known as swamp coolers, are environmentally friendly, cost-effective ways to make your home and outdoor areas more comfortable. A good evaporative cooler, used correctly ...
[4] [1] The typical system performance indicators for an adsorption refrigeration system are the coefficient of performance and the specific cooling effect. [4] The adsorbent is a solid, such as silica gel , activated carbon , or zeolite . [ 1 ]
