An apparatus for controlling an air distribution system

摘要

An apparatus for controlling an air distribution system for maintaining a rate of air flow in the system at substantially the target air flow rate, wherein the apparatus comprises:
means for detecting current speed and torque of said motor and generating said current speed signal and torque signal after detection;
means for receiving current speed signal and torque signal and calculating current air flow rate in the air distribution system wherein the calculated current air flow rate is being compared to the target speed signal of the air flow rate and the current air flow rate is adjusted according to the target speed signal of the air flow by generating a control signal; and
means for controlling the motor speed in response to the control signal for maintaining the rate of air flow in the system at substantially the target speed signal of the airflow rate.
