Interestingly, early cooling towers were positioned either on the rooftops of buildings or as free standing structures, supplied with air by fans or by relying on natural airflow. There are a number of different types of cooling towers, but they all serve the purpose of cooling and ventilating something that produces heat to operate.
Cooling towers can even use the evaporation of water to remove heat and cool the working fluid to near the wet-bulb air temperature. In the case of closed circuit dry cooling towers, the tower will rely solely on air to cool the working fluid to near the dry-bulb air temperature.
The first hyperboloid cooling towers were built in Holland at the close of World War I. Today, manufacturers of cooling towers produce cooling tower systems whenever a company needs coolin
