A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water’s temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.
How Cooling Towers Work?
Cooling towers are an important part of many industrial systems, providing cooling for large-scale operations and helping to keep temperatures in check. But how exactly do cooling towers work? Read on to learn more about the fundamentals of cooling tower operation.
Cooling towers use the process of evaporative cooling to regulate temperatures in industrial processes. In a cooling tower, hot water from the industrial process is pumped up to the top of the tower, where it is then sprayed out in a fine mist. As the water droplets fall, air is drawn into the tower and passes over the droplets, cooling them down. The cooled water then falls to the bottom of the tower, where it is pumped back into the system.
The hot water coming into the cooling tower is usually at a temperature of between 95-105°F (35-41°C). As the water passes through the tower, it is cooled to between 75-85°F (24-29°C). This cooling process is aided by the presence of louvers at the top of the tower, which create a draft and help to draw air into the tower.
The air that passes over the water droplets also carries away some of the heat from the water, which is known
