    • Airflow rates within a ventilation system are controlled using motor speed or torque and motor electric current or pressure. Fan speed or torque may be varied to compensate for differing restriction in ductwork, and may provide a constant airflow rate over a range of varying airflow restriction. Air handlers or air conditioning units may be mass produced in common configurations, and installed in different buildings or structures with different ductwork configurations. Methods operate a fan motor at a present speed or torque, sample speed or torque, sample current of the fan motor or pressure within the ventilation system, calculate a present airflow rate within the ventilation system, calculate a new input setting using the present airflow rate and a target airflow rate, change the speed or torque to the new input setting, and repeat these steps to converge on the target airflow rate, often avoiding overshoot.
    • 通风系统内的气流速率可通过电机转速或转矩,电机电流或压力进行控制。 可以改变风扇速度或扭矩以补偿管道系统中的不同限制,并且可以在变化的气流限制的范围内提供恒定的气流速率。 空气处理机或空调机可以通常配置大量生产,并安装在具有不同管道结构的不同建筑物或结构中。 方法以当前速度或扭矩,采样速度或扭矩,风扇电机的采样电流或通风系统内的压力来操作风扇电机,计算通风系统内的当前气流速率,使用当前气流速率计算新的输入设置 和目标气流速率,将速度或扭矩改变到新的输入设置,并重复这些步骤以收敛于目标气流速率,通常避免过冲。
