Cooling towers are heat rejection devices used in air conditioning, refrigeration, and industrial processes to transfer heat from a cooling system to the atmosphere. They are commonly used in combination with water-cooled chillers and condensers to provide a source of cool water for the cooling system.In a cooling tower, water is circulated through a heat exchanger, such as a chiller or condenser, where heat is absorbed. The water is then pumped to the top of the cooling tower, where it is dispersed over a large surface area, allowing heat to be transferred to the atmosphere through evaporation. This process cools the water, which is then recirculated back to the heat exchanger to continue the cooling process.Some of the common applications of cooling towers include:
- Air conditioning: Cooling towers are used in air conditioning systems to provide a source of cool water for water-cooled chillers, which remove heat from the building and transfer it to the atmosphere.
- Refrigeration: Cooling towers are used in refrigeration systems to provide a source of cool water for water-cooled condensers, which remove heat from the refrigeration system and transfer it to the atmosphere.
- Industrial processes: Cooling towers are used in industrial processes, such as chemical manufacturing, to cool process equipment and maintain optimal temperature conditions.
