Web2. Cooling Range - The difference in temperature betw een the hot water entering the tower and the cold water leaving the tower is the cooling range. 3. Approach - The difference between the temperature of the cold water leaving the tower and the wet- bulb temperature of the air is known as the approach. Webused. Wet cooling towers rely on the latent heat of water evaporation to exchange heat between the process and the air passing through the cooling tower. The cooling water may be an integral part of the process or may provide cooling via heat exchangers. Although cooling towers can be classified several ways, the primary classification is into dry
