Introduction Of Selection Standard Of Cross-Flow Closed Cooling Tower

1. The selection of the outdoor conversion temperature point of the cooling tower is directly related to the cooling time of the system. Assuming that the required water humidity of the air conditioner is 12.7°C, and the water temperature has risen by 4.5°C, depending on the cooling range of the cooling tower, the heat loss of the piping and the heat exchanger, the cooling form of the cooling tower can be switched when the outdoor wet bulb temperature is 8.2 °C.
2. Check the cooling capacity of the FRP cooling tower after calculating the wet bulb temperature according to the summer cooling load and outdoor accounting.
3. The heat exchanger of the direct cooling system should be a plate heat exchanger. Compared with the traditional shell and tube heat exchanger, the plate heat exchanger has the advantage of high efficiency.
4. In the direct cooling system, the chilled water pump in the cooling water circuit should be bypassed. In the cooling tower, the chilled water pump is turned off and the cooling water passes through the chilled water pump. At this moment, the circulating water can be supplied by the cooling water pump.
5. Since the cooling tower is mainly operated in the summer of the filtering season, the cooling water system in the area with low temperature in summer should be equipped with anti-freezing measures. If side pipes and heaters are installed.
