A cooling tower is a structure used to remove heat from water in industrial processes or HVAC systems. It works by allowing warm water to flow through the tower, where it is cooled by air that passes over it. This process helps maintain optimal temperatures in equipment and buildings. Cooling towers can be found in various settings, including power plants and large commercial buildings. They are essential for efficient operation, as they help prevent overheating and improve energy efficiency. Common types of cooling towers include mechanical draft and natural draft towers, each designed for specific applications.
