A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact in order to reduce the waterâ€™s temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated.
Cooling Tower Science
Water, which has been heated by an industrial process or in an air-conditioning condenser, is pumped to the cooling tower and flows through nozzles, spraying water onto the material called â€œfill,â€ which slows the flow of water through the cooling tower, and exposes as much water surface as possible for maximum air-water contact. As the water falls down through the cooling tower, it is exposed to moving air, which is being pulled through the tower by an induced draft fan
