How air cooler works

Air coolers operate on the simple principle of evaporation. So, instead of using chemicals or refrigerants to cool a space, air coolers use two natural elements to provide cooling - fresh air and water. Air coolers cool the room the way sweating cools your body. Water vapour is introduced into the air, which raises humidity and lowers the temperature. This is a very ancient method of cooling. Traditional Indian homes and villages used porous earthen vessels filled with cool water to create a pleasant indoor environment. Since the method is simple, an air cooler doesn’t incorporate complicated machinery or special chemicals to work. All this results in lower operating costs.
