How many problems should be paid attention to when cooling equipment is used?

1. The selection of outdoor switching temperature point of cooling tower cooling mode is directly related to the cooling hours of the system. Assuming that the required water supply humidity at the end of the air conditioner is 12.7 ℃ through calculation, and considering the cooling range of the cooling tower, the heat loss of the pipeline and heat exchanger to increase the water temperature by 4.5 ℃, it can be obtained that the cooling mode of the cooling tower can be switched when the outdoor wet bulb temperature is equal to or lower than 8.2 ℃. 2. After the cooling tower in the system is selected according to the summer cooling load and the summer outdoor wet bulb temperature, its cooling capacity under the cooling tower cooling mode should also be checked. 3. Plate heat exchanger shall be selected as the heat exchanger in indirect cooling system. Compared with the traditional shell and tube heat exchanger, the plate heat exchanger has high heat exchange efficiency. 4. In the direct cooling system, the chilled water pump in the cooling water loop should be set with bypass. In the cooling tower cooling mode, the chilled water pump is closed, and the cooling water is passed by the chilled water pump. At this time, the circulating water power is provided by the cooling water pump. Therefore, conversion of special cooling pump shall be considered in system design.
