An evaporative cooling system is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by employing water's large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation), which can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants.

Quality Control Features

1. Compared to the conventional systems, the fill type system attains maximum saturation.
2. The design is compact and pre-fabricated, consumes less space, which is only about forty percent of that occupied by conventional systems.
3. There is no requirement for masonry work and can be placed outside the building too.
4. Consumption of power is negligible when compared to spray machines. This is due to low drop in pressure and low pump.

Evapourative Cooling Effeciency

1. With the latest awareness on energy efficiency, evaporative cooling systems are gaining a lot of popularity Owing to the simple technology employed, the cost of the evaporative cooling system is cheaper
2. The systems operate on 120V electricity which implies that they don't require special circuits of high-amperage unlike many air conditioners. It could be plugged into an outlet nearby
3. The air gets moisture as a result of evaporative cooling. This helps in preventing the drying out of fabrics and wood furniture. The moist pads are good air filters and thus trap some pollen and dust. As the pads are kept wet, the trapped particles get flushed and caught in the cooler bottom.
4. Not much of ductwork is needed in evaporative cooling systems. For a system that is newly installed, a short duct helps to direct the air that is cooled to the building's central point.
