May I ask, what is the difference between a closed cooling tower and an open cooling tower?


There are two types of cooling towers: open cooling towers and closed cooling towers. What are the differences between closed cooling towers and open cooling towers?


1. Open cooling tower

The cooling principle of the open cooling tower is to spray the circulating water on the glass fiber filler by spraying, and to achieve heat exchange through the contact of water and air, and then the fan drives the air flow in the tower to exchange it with water. The hot air flow after being taken out is cooled.


This type of cooling method requires less investment in the first phase, but the operating cost is higher (water consumption and power consumption).


2. Closed cooling tower

The cooling principle of a closed cooling tower is, in simple terms, two cycles: an internal cycle and an external cycle. Without filler, the main core part is copper tube surface cooler.


①Circulation in closed cooling tower: docking with the target equipment to form a closed circulation system (the circulating medium is soft water). Cooling the target equipment and taking the heat from the target equipment to the cooling unit.


②Outside circulation of closed cooling tower: In the cooling tower, cooling the cooling tower itself. It is not in contact with the internal circulating water, but only conducts heat dissipation through the copper tube surface cooler in the cooling tower. In this cooling mode, the motor operation is set according to the water temperature through automatic control.


Two cycles, when the ambient temperature is high in spring and summer, two cycles are required to run simultaneously. In autumn and winter, the ambient temperature is not high, and in most cases, only one internal cycle is required.


The closed cooling tower is stable and safe, and is suitable for continuous operation system. Open cooling towers require frequent shutdowns for maintenance and are not suitable for systems that require long-term operation.
