Smart frequency conversion control cooling tower equipped with permanent magnet direct drive motor

Abstract

The invention discloses a smart frequency conversion control cooling tower equipped with a permanent magnet direct drive motor. The smart frequency conversion control cooling tower comprises a tower body and a water collection base plate, wherein the bottom of the tower body is fixed with the water collection base plate through bolts, a packing support is obliquely installed inside the tower body,packing is filled in the packing support, a fan protective cover is fixed in the center of the top of the tower body through the bolts, and a permanent magnet direct drive motor is fixed to the top of the fan protective cover through a flange, the output shaft of the permanent magnet direct drive motor is fixedly provided with a cooling fan through a nut and a limiting ring, water distribution devices are arranged on the periphery of the top of the fan protective cover, water inlet pipes are arranged at the tops of the water distribution devices correspondingly, the bottoms of the water distribution devices are fixedly provided with water distribution nozzles through threads. The smart frequency conversion control cooling tower equipped with the permanent magnet direct drive motor has thebeneficial effects that the device has higher cooling capacity by spraying and packing with the water distribution nozzles, and the time of cooling water through the tower body is prolonged; the permanent magnet direct drive motor is adopted for driving, so that the rotating speed and the torque can be adjusted according to requirements, the working noise of the device can be reduced, the energyconsumption is reduced, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a cooling tower equipped with a permanent magnet direct drive motor intelligent frequency conversion control. Background technique [0002] At present, the cooling tower is the terminal heat dissipation equipment of the air conditioning system, and its energy consumption has been deeply concerned. The common energy-saving control is to divide the cooling tower into multiple modules. At night or when the load is low, reduce the number of modules (fans) used to reduce The energy consumption and noise of the cooling tower, but when the load is heavy, due to the superposition of multi-module noise, the overall noise will not be lower than that of single-module cooling, and the energy consumption will increase. At the same time, it will increase the cost of debugging and operation and maintenance. Some cooling towers of air conditioning systems are driven by frequency conversion...

[0002] At present, the cooling tower is the terminal heat dissipation equipment of the air conditioning system, and its energy consumption has been deeply concerned. The common energy-saving control is to divide the cooling tower into multiple modules. At night or when the load is low, reduce the number of modules (fans) used to reduce The energy consumption and noise of the cooling tower, but when the load is heavy, due to the superposition of multi-module noise, the overall noise will not be lower than that of single-module cooling, and the energy consumption will increase, and it will increase the cost of commissioning and operation and maintenance

There are also cooling towers in some air-conditioning systems driven by variable frequency or double-speed motors, because they are often driven by traditional gearboxes or belts, the efficiency of the transmission system will be much lower, and the effect of energy saving and noise reduction will not be significant
