Working of Evaporative Cooling System

An evaporative cooler (also known as swamp cooler, swamp box, desert cooler or wet air cooler) is a device that uses the concept of evaporation of water for cooling a room. This evaporative cooling system differs from typical air conditioning system (uses vapor compression or absorption refrigeration cycles). This type of cooling is more preferable because of the fact that converting water to vapor needs relatively large amount of heat, thus decreasing the temperature of surroundings.  This type of cooling uses much less energy compared to other cooling techniques. In extreme heat conditions, this type of cooling adds conditioning to air with more moisture thus making more comfortable surroundings.

Evaporative conditioning use evaporation technique to cool air. A pump in the cooler circulates water from the reservoir on to the cooling pad, cooling the pad. A fan draws air from outside the cooler through the wet pad. Drawn air that passes the pad is cooled down by evaporation. For effective cooling, it is always suggested that all the cooling pads should be completely saturated at all times during operation. The system fan and motor should be of an appropriate size to deliver good air flow.

Few companies use advanced technology with a clever design feature that achieve best performance compared to any other air conditioner.
