Explanation on cooling towers

Cooling tower operation.


Hot water from closed systems are being cooled by water circulated in an open system, i.e. a cooling tower.
In the cooling tower the water is cooled by heat exchange from the water into the air.
The water is sprayed from the top of the cooling tower and drip onto a hive-like structure in order to increase the surface area and create a greater heat exchange, and then drip down to a storage tank and returned to the process ----> to cool the closed system.

During this process two things occur:

1. Some of the circulated water is lost by evaporation.
2. As a result of evaporation, the concentration of salts in the water increases. Therefore,
It is essential to perform regular drainage of the system, monitored by a conductivity controller.
