WebAn evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from … WebThe cooling of a material through evaporation is caused due to the latent heat of material on which liquid is present. Thus, by losing heat the material gets cold. For example, when a little amount of ether or petrol is put at the back of our hand and waved, the evaporation takes place easily and our hand feels cool.
WebAn evaporative-cooling system consists of an intake chamber, filter (s), supply fan, direct-contact or indirect-contact heat exchanger, exhaust fan, water sprays, re-circulating water pump, and water sump. Evaporative-cooling systems are characterised by low energy use compared with refrigeration cooling. They produce cool and humid air and are ... WebEvaporation Definition: Evaporation causes cooling is the transformation of a liquid or solid into vapour. When you spray perfume on your body, it makes you feel colder. The same can be said for acetone and water. This is a result of evaporation, or the transformation of materials from a liquid to a gaseous state.
