ACI Constant Flow Supply Blower Dedicated Converter
The constant flow supply type blower frequency converter is a
frequency conversion speed control device designed specifically for
fans, aiming to achieve constant control of the supply air volume
by adjusting the fan speed. Its core function is to adapt to
different working conditions, ensure stable air output of the fan,
while also considering energy conservation, efficiency, and system
stability.
Key functional features
Constant flow control
By using built-in flow sensors or pressure sensors (indirectly
reflecting flow), combined with PID control algorithm, the fan
speed can be adjusted in real time. When the system resistance
changes, the frequency converter automatically adjusts the motor
frequency to maintain a constant air output.
- The relationship between flow rate and speed: The air volume (Q) of
the fan is directly proportional to the speed (n) (Q ∝ n), and the
air volume can be precisely controlled by adjusting the speed.
- Pressure compensation: When the resistance of the pipeline changes,
the speed is corrected through pressure feedback to avoid flow
fluctuations.
Variable frequency speed regulation technology
Using AC-DC-AC frequency conversion method, the power supply is
converted into AC power with adjustable frequency to drive the fan
motor. Its core advantages include:
- Soft start: Reduce the starting current and minimize the impact on the power
grid and machinery.
- Stepless speed regulation: Wide speed adjustment range, fast response speed, and strong
adaptability.
- Energy saving effect: By reducing the speed and energy consumption, the energy saving
rate can reach 20% -60% (depending on the operating conditions).
