The operation characteristics of the closed cooling tower in the connecting season + The closed cooling tower is a kind of equipment that puts the shell and tube heat exchanger in the tower and reduces the temperature according to the circulating air, spraying water and cooling the circulating water heat exchanger. In recent years, it has been more widely used in power electronics technology, mechanical processing and manufacturing, central air conditioning system and other fields.

This paper introduces the key points to pay attention to when designing the down-flow cooling tower. The selected finished product cooling tower needs to meet the requirements of "glass fiber reinforced plastic cooling tower Part 2: Large glass fiber reinforced plastic cooling tower" GB7190.2-1997.

Let's take a look at the cold protection problems of places where countercurrent cooling towers operate in some time ranges. The cold proof of the water circulation system of the internal structure of the countercurrent cooling tower can be added glycol solution or elevated heating equipment. The zero ambient temperature of ethylene glycol solution shall be set below the local lower ambient temperature.

Countercurrent cooling tower manufacturers: The water supply of circulating water cooling water system includes evaporation loss, drift loss, sewage loss and drainage loss. It is appropriate to choose a cooling tower with low energy consumption and less bleaching water, and the water recharge of air conditioning cooling water is controlled in the total circulation water of the system by 1.2 to 1.5 percent. When the water quality is good, take a small value; When the water quality is poor, take a larger value.

The external envelope structure of the cooling tower, the tower of the mechanical ventilation cooling tower and the wind-type natural ventilation cooling tower are closed, and have the function of supporting, maintaining and organizing the appropriate air flow; The tower body of the open cooling tower is made open along the tower height, and the natural wind can enter the tower body.
