Abstract

An air tower adapted to be located within a compartment of a refrigeration appliance comprises a first plenum chamber in fluid communication with a first compartment of the refrigeration appliance, a second plenum chamber in fluid communication with a second compartment of the refrigeration appliance, a damper connecting the first plenum chamber to the second plenum chamber, and a movable part within the damper configured to be moveable between a first position and a second position. When moved to the first position, the movable part is relatively closer to interior side walls to thereby restrict air flow from the first plenum chamber to the second plenum chamber. When moved to the second position, the movable part is relatively further away from the interior side walls to thereby permit more air flow from the first plenum chamber to the second plenum chamber.
