摘要：
A pressure independent variable air volume valve (VAV valve) functions as a pressure dependent valve upon detecting a malfunctioning airflow indicator. Under normal operating conditions, the VAV valve modulates supply airflow to a comfort zone in response to the zone temperature and the rate of airflow through the valve. If the airflow indicator fails, the VAV valve modulates the supply airflow in response to the zone temperature, independent of the airflow indicator.
