Overview of the specific functions and working principles of frequency converters in all-steel fume hoods
The operation of the frequency converter in the all-steel fume hood will directly affect whether it can operate stably, so everyone can usually pay more attention to the fume hood related content. Next, the editor will introduce to you its specific functions and its related working principles, so that you can use it better in the future.
inverters are widely used in all-steel fume hoods. Compared with the previous fume hoods, the air volume is adjusted by adjusting the opening of the damper. In this way, regardless of the user's demand, the fan must run at full speed, and changes in operating conditions cause energy to be consumed through damper throttling losses.

All steel fume hoodUsing a fan and a frequency converter, stepless speed regulation can be achieved. According to site requirements, the frequency of the frequency converter can be increased or decreased to change the fan speed to obtain the required air volume.
uses a fan and an inverter to realize two-stage speed regulation. According to the site requirements, set the second-stage frequency of the inverter. When any fume hood is turned on, the inverter outputs a set frequency to obtain an air volume. When the two fume hoods are turned on, the frequency converter outputs another set frequency to obtain another air volume. This second frequency can be set arbitrarily according to site requirements.
three devices use one fan and one frequency converter, which can realize three-stage speed regulation. According to the site requirements, set the three-stage frequency of the frequency converter. When any fume hood is turned on, the frequency converter outputs a set frequency to obtain a certain air volume. When any two fume hoods are opened, the fans will run at full speed regardless of the user's demand, and changes in operating conditions will cause energy to be consumed through damper throttling losses.
