How should the closed cooling tower be used to save electricity

The closed cooling tower is a device for cooling water, which is widely used in air-conditioning circulating water systems and industrial water, which can bring great convenience to users. In order to reduce the cost of use, some users hope to save more power when using the device. So how can the closed cooling equipment be used to save electricity? 1. In non-high temperature seasons, that is, in winter and transitional seasons, the cooling tower fan load is small, and the outdoor ambient temperature is low. Generally, forced cooling is not required. Therefore, the cooling equipment fan can be turned off or its frequency can be converted according to the actual situation. control. 2. For conventional cooling water pumps, when the temperature difference between the inlet and outlet of cooling water is less than 4-5 degrees, the phenomenon of 'small temperature difference, large flow' will appear. At this time, the water pump does a part of useless work, and the water pump is controlled by frequency conversion or small pump. Replacing a large pump can save a lot of electricity. 3. Adjust the speed of the water pump. According to the relationship between the pump flow Q, the pressure P, the number of revolutions n and the power N: it can be seen that adjusting the speed can greatly adjust the operating power of the pump. The power saving of the water pump is mainly to adjust the power consumed by the water pump reasonably under the premise of meeting the required flow and head, rather than relying on throttling to adjust. 4. When the cooling water pump is not in one-to-one form, but in parallel form, the number of pumps to be operated should be controlled according to the temperature difference between the inlet and outlet of the cooling water. Several parallel pumps are matched in size, and different specifications of pumps are operated according to the change of demand load. It is more energy-saving, and has good effect on the frequency conversion control of the water pump.
