Is the centrifugal fan plugging the air inlet motor?
That is, the centrifugal fan control mode, from the ordinary control mode to frequency control.
If it is to take the energy saving way to block the air intake to save electricity, it would be better to directly change the centrifugal fan control mode is simple and convenient
However, the motor is still running at high speed, the corresponding mechanical loss and other losses, but still continue to consume, and block the air intake of this way to save the electricity is much greater.
Centrifugal fan to block the air inlet, this time because the motor load to reduce, can indeed reduce the amount of electricity waste
So that the production can be arbitrary control of the centrifugal fan speed, the need for large air flow when the motor to increase the frequency, the need for air to reduce the motor running hours. So as to achieve the true sense of energy conservation.
