The evaporative technology uses the energy of the outside air to evaporate the water, which lowers the overall temperature and results in the cooling of the air. However, when this energy is converted into latent heat, it binds the cool air with some humidity as well. Since the energy or electricity consumed is only by the fan and pump, the efficiency is nine times more than a compressed air conditioning system. It is therefore the most common and dominant form of cooling. Since the average consumption of power is around 150 to 300 watts, which cements the fact that an Evaporative Air Cooler uses almost 75-80% less energy than the traditional air conditioning system. A natural mechanism of lowering the temperature of the hot air and allowing significantly cool air combining with an efficient humidity control reduces the need and hence the cost of energy substantially for the user.
