FRP cooling tower in the maintenance of the time should pay attention to those problems

In the air conditioning system, the cooling water is often used to absorb the heat from the condenser of the refrigerator. Shandong Anqiu City Huabao FRP cooling tower experts, from the economic considerations, the cooling water is often recycled t this need to make this part of the water in the cooling equipment and then cooled. By the (two cooling water in the cooling of these cooling equipment with the outside air contact with the air pollutants such as dust, debris, bacteria, soluble solids, etc., at any time may be into the cooling water system to microbial propagation, Resulting in biological mud. At the same time, if the system of make-up water without softening, the water in the cooling tower that part of the water will remain in the cooling water system, with the evaporation process, the circulating cooling water dissolved salt , So the hardness of water is increasing. In addition, there is the role of dissolved oxygen in the water, so that the metal pipe scaling, corrosion due to the above reasons, the flow of water system will gradually hide the small, condenser, absorber and other equipment to reduce the heat transfer efficiency. It is estimated.

In the lithium bromide absorption belt with the machine, the condenser heat transfer tube wall scale increases lmm, the refrigerator cooling capacity will drop 2O, and the system's transmission and distribution capacity is reduced, energy consumption increases. The end may also occur water blocking phenomenon, or even an accident. It is an important measure to save water, save energy, protect the environment and benefit mankind by developing a cooling tower which can reduce the temperature of water and keep the water quality clean.
(A) closed glass fiber reinforced plastic cooling tower working principle
Closed FRP cooling training is composed of plate, fan, pipeline pump, nozzle, row pipe, retaining plate and so on.

The higher temperature water from the condenser or process equipment is pressurized by the cooling water pump to the cooling coil of the enclosed cooling tower. On the other hand, the water in the cooling tower pond is pumped into the spray pipe by means of a pipeline pump and then sprayed on the outer surface of the cooling coil. Vaporize the heat of the cooling water. So that the temperature of the cooling water is reduced. At the same time, by the installation of the fan above the suction plate suction. So that the air from the - and the upper flow through the cooling coil, so not only can strengthen the cooling coil on the outer surface of the Yan, but also can take away the evaporation of water vapor. To accelerate the evaporation of water to improve the cooling effect.
(2) Closed cooling tower performance test
In order to conduct a comprehensive test on the thermal performance of the enclosed cooling tower, the cooling tower performance test bed and experimental device flow were established in Qingdao Sanhe Environmental Protection Equipment Factory.

9. Spray water pump
Theoretical and experimental studies have shown that. The temperature of the wet air bulb, the inlet temperature of the cooling water, the flow rate of the cooling water, the amount of water sprayed, and the air flow rate have an effect on the performance of the closed cooling block. The performance of the closed cooling block was tested in August 1994. The air temperature of the mouth of the wet bulb increased, the cooling capacity of the cooling tower decreased, the cooling water outlet temperature increased. on the contrary. If the population air wet bulb temperature drops. The cooling capacity of the cooling tower will be increased and the cooling water outlet temperature will be reduced. The cooling capacity of the refrigerator increases.

3 Conclusion
Closed cooling towers can effectively reduce the cooling water temperature. Can keep the cooling water from pollution, thereby improving the operating efficiency of the refrigerator to extend the life of the refrigerator.
