indirect evaporative cooling

Indirect evaporative cooling is a method of cooling air without adding humidity directly to the space. It uses a heat exchanger where warm, outside air bypasses a moist surface that cools it through evaporation of water. This process reduces the temperature of the air without increasing its moisture content, then the cooled air is directed into the building. Meanwhile, the exhaust air absorbs the heat through the heat exchanger, maintaining indoor humidity levels. This technique is energy-efficient and environmentally friendly, especially in dry climates, providing cooling without the use of traditional air conditioning.
