If "AC Fan" has the function of energy regulation that, in use, it can be done while maintaining the effect, but also save some energy consumption, but energy regulation, there are three main methods are: frequency control and slide valve stepless adjustment stepless adjustment belong. Stepless adjustment, energy saving, noise and vibration, good starting performance while also reducing interference to the power supply system. Currently used in air-cooled heat pump compressor energy adjustment method has several control units, compressor clearance operation, unloading cylinder adjustment (piston) Frequency (scroll) stepless slide valve (screw) from energy regulation mode, you can see the introduction of speed control. Choose what kind of adjustment is a different way to achieve results, we need to adjust the energy of the wind turbine based on the actual situation and the actual needs of the fan sites, so as to make the configuration process more successful.
