Open circuit cooling tower performance

As you know, the cooling of water in cooling towers is achieved through the movement of water in the device and the evaporation process, on the other hand, due to the evaporation of water, the salts and impurities in it remain as deposits inside the cooling tower device. stayed

Sediment formation in cooling towers has a direct relationship with the quality of water entering the device, therefore, in projects where the water circulating in the cooling tower must be of high quality and the possibility of sediment formation in the device is also low, cooling towers The circuit breaker is used.

 With the airflow inside the cubic cooling tower and the cooling of the circulating water, some of the water in the cooling tower is always evaporated. After cooling the water in the cooling tower, cool water is collected in the basin and the lower part of the device and is directed to the chiller or the production process by circulation pumps.
