INTEGRATED AIRFLOW CONTROL FOR VARIABLE AIR VOLUME AND AIR HANDLER HVAC SYSTEMS TO REDUCE BUILDING HVAC ENERGY USE

摘要

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.

1. An airflow system, comprising:
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 having a processor and a memory, disposed in operative communication with the damper apparatus and the VAV apparatus, the controller configured to: determine a percentage of outside air provided to the airflow system by the damper apparatus based upon at least one of (i) an air temperature, (ii) an air pressure, and (iii) a damper position of a damper apparatus of the airflow system; determine a minimum flow volume provided by the VAV apparatus of the airflow system, the minimum flow volume relating 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.
