If the fan has the function of energy regulation, and that is in use can be done while maintaining the effect of small axial fans, but also save some energy consumption performance axial fan, but there are three main methods of energy regulation, namely: Frequency stepless speed control and slide valves are stepless adjustment. Stepless adjustment, energy saving, noise and vibration, good starting performance while also reducing interference on the power supply system. Currently used in air-cooled heat pump compressor energy adjustment method to control the number of units, compressor clearance operation, unloaded cylinder adjustment (Piston) Frequency (scroll) spool stepless adjustment (screw) from energy regulation You can see the introduction of several ways to control. Choose what kind of adjustment is a different way to achieve results, we need to adjust the energy of the fan according to the actual situation and the actual needs of the fan sites, so as to make the configuration process more successful. Calculate the required fan static pressure pipeline under the circumstances: 1, according to the amount of wind and wind speed (wind speed 10-15 m / s or so) to determine the cross-sectional area of ??the duct. Duct aspect ratio should not exceed 2: 1 (in order to save material and reduce the drag). 2, according to the wind speed, the wind pipe cross-sectional area, elbows, reducers, etc. to calculate the drag (ie, the required fan static pressure). According to the calculated air volume, static pressure. Select the appropriate fan.
