Extended data:
Several problems in cooling operation of FRP cooling tower;
1, the choice of outdoor conversion temperature point of cooling tower cooling form is directly related to the cooling hours of the system. After calculation, it is assumed that the required water humidity at the air conditioning terminal is 12℃ and 7℃, and the water temperature rises by 4℃ and 5℃ respectively considering the cold fluctuation of the cooling tower and the heat loss of the pipeline and heat exchanger. It can be concluded that the cooling mode can be switched to the cooling tower when the outdoor wet bulb temperature is equal to or lower than 8℃ and 2℃.
2. In the system, after selecting the cooling tower according to the summer cooling load and the wet bulb temperature calculated outdoors in summer, the cooling capacity of the cooling tower should also be checked.
3. The heat exchanger in indirect cooling system should choose plate heat exchanger. Compared with the traditional shell-and-tube heat exchanger, the plate heat exchanger has high heat transfer efficiency.
4. In the direct cooling system, the chilled water pump in the cooling water loop of the FRP cooling tower should be bypassed. In the cooling form of the cooling tower, the chilled water pump is closed and the cooling water passes through the chilled water pump. At this time, the circulating water power is provided by the cooling water pump. Therefore, in the system design, it is necessary to consider the conversion of special cooling pump.
5. In the design of direct cooling system, attention should be paid to the sterilization and filtration of cooling water to avoid blocking the tail pipe.
6. Considering that the cooling range (the difference between the outlet temperature of the cooling tower and the outdoor wet bulb temperature) of the cooling tower decreases with the increase of the size of the cooling filler, the method of series cooling towers can be adopted to increase the cooling effect of multiple groups of cooling towers, improve the outdoor conversion temperature of the cooling towers, and then increase the cooling hours.
7. As the cooling tower mainly operates in the winter filtration season, anti-freezing equipment should be installed in the cooling water system in areas with low temperature in winter, such as setting bypass pipes and adding heaters. ?
