Abstract
A constant air volume control method includes acquiring a target air volume for a ventilation device, detecting a present rotational speed and a present torque of a motor of the ventilation device, selecting an air volume calculation formula corresponding to the target air volume according to a preset correspondence relation between air volumes and air volume calculation formulas, calculating a present air volume corresponding to the present rotational speed and the present torque, and adjusting motor parameters of the ventilation device according to a difference between the present air volume and the target air volume.
