The most basic part of cooling, Greenpad, is kept constantly wet by continuously circulating water. Hot and dry air passes through the wet pad by means of a fan. During this passage, heat transfer occurs between the air and water. As a result, cool and moist air is given to the environment to be cooled.
Water has a high heat transfer coefficient, so it has a high tendency to evaporate. It absorbs heat from its surroundings during evaporation. When water comes into contact with the air, it cools the air by taking heat from the air and increases the amount of water vapor in the air.
Evaporative cooling cools the air by bringing the air into contact with as much water as possible. This method provides an effective way to cool the environment in a natural and energy-efficient way.
