Water is used widely as a cooling medium in processes for many industries and public buildings. The use of an evaporative cooling tower is still the most effective method of heat transfer. Heat is transferred from hot process fluids into the cooling water through a heat exchange surface; consequently, the cooling water heats up. The evaporation of a small percentage of this cooling water in a cooling tower, then reduces the temperature of the cooling water, allowing it to be used for cooling again. Make-up water is used to replace the evaporated water.
Evaporative condensers are often used to cool closed systems whereby pipework containing hot process fluids is sprayed with water to remove heat from the system. The primary objectives in the design, operation and effective treatment of cooling water systems include efficiency in heat transfer, minimisation of energy and water usage, and safe, reliable operation.
When operating a cooling system, there are several considerations to ensure the achievement of these objectives, which include the control of scale, corrosion, fouling, and the control of microbiological contamination including Legionella spp
