Cooling towers are towers that are used to transfer waste heat to the atmosphere. Cooling towers may use the evaporation of water to remove heat and cool the working fluid to near the wet-bulb air temperature. They may also use only air to cool the working fluid to near the dry-bulb air temperature. Cooling towers are used in oil refineries, petrochemical plants and power stations.
