Abstract
A zoned HVAC system comprises an HVAC unit including a climate control system and an air mover. In addition, the system comprises a supply air duct in fluid communication with the outlet of the HVAC unit. Further, the system comprises a return air duct in fluid communication with the inlet of the HVAC unit. Still further, the system comprises a plurality of zones positioned between the supply air duct and the return air duct. Moreover, the system comprises a bypass duct extending between the supply air duct and the return air duct. The bypass duct includes an active bypass damper having an open position, a closed position, and a plurality of partially opened positions. The system also comprises a control device configured to control the position of the bypass duct.
