direct evaporative cooling

Direct evaporative cooling is a method of lowering air temperature by adding moisture. It works by passing warm, dry air through a wetted material, like a moist pad or pad-like surface. As the air contacts the moisture, some of it evaporates, absorbing heat and reducing the air's temperature. The cooled, humidified air is then circulated into the building or space. This process is energy-efficient and environmentally friendly, especially in dry climates, because it uses the natural cooling effect of evaporation instead of traditional refrigerants.
