is a physical phenomenon in which evaporation of a liquid, typically into surrounding air, cools an object or a liquid in contact with it.
A simple example of natural evaporative cooling is persiration, or sweat, which the body secretes in order to cool itself. The amount of heat transfer depends on the evaporation rate, which in turn depends on the humidity of the air and its temperature, which is why one sweats more on hot, humid days.
Evaporative cooling is a very common form of cooling buildings for thermal comfort since it is relatively cheap and requires less energy than many other forms of cooling.
are devices that cool air through thesimple evaporation ofwater.They differ from refrigeration;or absorption air conditioning, which use vapor-compression or absorption refrigeration cycles.
Evaporative cooling is especially well suited for climates where the air is hot and humidity is low.
In dry climates, the installation and operating cost of an evaporative cooler can be much lower than refrigerative air conditioning.
Anand air cooler uses energy efficient technology to bring fresh air into your home or office with zero impact on the ozone layer,
helping to reduce the greenhouse effect.
