How Evaporative cooling works
Evaporation cooling is to cool and humidify air by water evaporation to absorb heat. Do you ever wonder why you feel cooler by the ocean? It is because hot air is blown over water causing some of the water to evaporate and absorb heat. Evaporative air cooler The Cool Air

working this evaporation principle. In an evaporative cooler a circulation pump keeps the cellulose filter pads fully soaked. As warm air passes over wet filter pads water naturally evaporates into the air. The air is cooled as it gives up the heat required to evaporate the water.
