A closed cooling tower is actually a transpiring cooling tower, a combination of a closed cooling tower cooler and a wet cooling tower. It is a horizontal transpiring cooling tower. The process fluid flows through the tube and the air flows outside the tube. The two do not touch each other. The closed cooling tower is a modification and development of the traditional cooling tower. After the water in the reservoir at the bottom of the tower is pumped by the circulating pump, it is sent to the outside of the pipe to be evenly sprayed down. It does not touch the process fluid hot water or refrigerant and the air outside the pipe, and becomes a closed cooling tower, which enhances heat and mass transfer by spraying water.
Closed cooling tower is suitable for various cooling systems that require high circulating water quality, and has application prospects in electric power, chemical industry, steel, food and many industrial sectors. On the other hand, compared with air-cooled heat exchangers, transpiration cooling towers use the latent heat of transpiration of the water on the lower side of the tube, which significantly enhances the heat and mass transfer on the air side, and also has obvious advantages.
The advantages of closed cooling tower products The antifreeze of closed cooling tower has two parts: spray water system and internal circulating water system (softened water). Type cooling tower is mainly used in equipment that requires very high turbidity of the heat dissipation medium. Because of its poor cooling effect, high cost, large floor area and other factors, it will not be used if it is not necessary. Open cooling towers are widely used, and it is recommended to start with open towers. Echo 0|Comment on the antifreeze problem of the spray water system. An electric heater is usually added to the water pool. Generally, the spray water is turned on when the spray water is lower than 5℃, and it is stopped when the spray water is above 8℃. The temperature probe transmits the signal to the control cabinet to automatically control the start and stop of the electric heater. The power selection of the electric heater is determined according to the circulating water volume and the outside air temperature. The antifreeze of the internal circulating water system can be added with glycol solution or electric heating equipment. Consult our company for the formulation of the glycol solution. For larger cooling system occasions, you can consider digging a pool to put spray water into it, which can save electricity costs due to electric heating operation, and you can also put medicine in the pool to improve the water quality of the spray water.
