Abstract
An airflow system includes a damper apparatus configured to adjust a flow volume of recirculated air and a flow volume of outside air within the airflow system, a variable air volume (VAV) apparatus disposed in fluid communication with the damper apparatus, and a controller disposed in operative communication with the damper apparatus and the VAV apparatus. The controller is configured to determine a percentage of outside air provided to the airflow system by the damper apparatus, determine a minimum flow volume provided by the VAV apparatus of the airflow system, which relates a required flow volume of outside air provided by the VAV apparatus to a zone and the percentage of outside air provided to the airflow system by the damper apparatus, and adjust a flow volume of air provided by the VAV apparatus to the zone based upon the determined minimum flow volume provided by the VAV apparatus.
