Three circulation systems for cross flow closed circuit cooling tower and their advantages
Dec 10, 2018

In the internal circulating water system of the  cross flow closed circuit cooling tower, the circulating water cooled in the coil is discharged from the tower body during operation, and is sent to the heat source (cooled equipment) by the circulating water pump of the system, and the circulating water is heated by the heat exchange and enter the coil to cool.

In the external circulating water system of the  cross flow closed circuit cooling tower, the external spray water will pass through the heat exchange with the coil and the packing to achieve the purpose of cooling the circulating water inside the coil, and then fall into the lower tank and be sent to the spray by the spray water pump. The sink is circulated again.

The inner circulation of the  cross flow closed circuit cooling tower is exchanged with the water and air by the cooling water through the coil to prevent the water pollution caused by the direct contact between the cooling water and the air. Since the spray water is pre-cooled by the PVC packing, the heat exchange effect is more obvious.
