Let's take a look at the cold protection problems of places where countercurrent cooling towers operate in some time ranges

There are two main types of cold protection for countercurrent cooling towers: spray air conditioning water systems and external water circulation systems (softened water treatment).

The cold protection problem of spraying air conditioning water system is usually to lift the electric heating device in the water tray, which is generally opened when the spraying water is less than 5 ° C and stopped above 8 ° C. The temperature sensor transmits the signal to the control box to automatically control the start and stop of the electric heating device of the system. The efficiency of the electric heating device is selected according to the circulating water volume and the external temperature.

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.

For relatively large refrigeration system places, you can choose to dig reservoirs to spray water into them, which can save the power consumption cost due to the operation of electric heaters, and can also promote drugs in the reservoir to improve the spraying water body.

Analysis of countercurrent cooling tower why to add circulation water tank

Why do counter-current cooling towers need a circulating water tank? Since it is characterized by the liquid closed cycle system according to the process, and then transport sufficient power energy, therefore, in our coil heat exchanger, the liquid and circulating vapor body and self-sprinkler water are heat exchangers, and the closed cycle system is carried out.

Push-in stainless steel sinks reduce energy consumption. The countercurrent cooling tower has a series of characteristics such as good thermal insulation performance, good processing quality, anti-scaling, and stable cooling characteristics of mechanical equipment. The structure of this equipment is mainly composed of heat exchanger coil fan, shell and pillar, fire exhaust fan and motor, plus water distribution spray system, water collection filter, but also contains many prefabricated components such as centrifugal pump and pipe. However, it is important to note that in most cases, it has to be equipped with a storage tank.

For countercurrent cooling tower storage tank, most of its common raw materials are stainless steel sheet or glass fiber reinforced plastic raw materials, so it will have good tensile strength corrosion resistance characteristics. Its shell is square, from the product design point of view, it is also more beautiful, but also the general water storage tank from 0.5 square to 20 square. As far as the bottom of the stainless steel sink is concerned, we will generally configure centrifugal pumps and water pipes.
