    • A method for controlling a variable airflow apparatus to prevent processor overflow and underflow, with the variable airflow apparatus including an airflow sensor for providing an airflow sensor signal, a stored relationship between the airflow sensor signal and an airflow value, a damper for varying airflow, and an actuator for positioning the damper. The method includes energizing the airflow controller, determining either a minimum allowed airflow value based on the stored relationship between the airflow signal and an airflow value, or determining a maximum allowed airflow value based on the stored relationship, and periodically positioning the damper to provide an airflow value within a range limited by the minimum allowed airflow value or the maximum allowed airflow value in response to a signal from the airflow controller.
    • 一种用于控制可变气流装置以防止处理器溢出和下溢的方法,其中可变气流装置包括用于提供气流传感器信号的气流传感器,气流传感器信号和气流值之间的存储关系,用于变化气流的阻尼器, 以及用于定位阻尼器的致动器。 该方法包括通电气流控制器,基于所存储的气流信号与气流值之间的关系确定最小允许气流值,或者基于所存储的关系确定最大允许气流值,以及周期性地定位阻尼器以提供 响应于来自气流控制器的信号,由最小允许气流值或最大允许气流值限制的范围内的气流值。
