US 10,190,360 B1 · Hollow core door with perimeter air flow and multiple damper panels

Abstract

A hollow core door apparatus for preventing the build up of pressure in a room includes an inside door skin and an outside door skin, and the door skins include openings through which air flows. A center panel is disposed between and spaced apart from the skins. The center panel has an outer perimeter defined by notches through which air flows. Tabs between the notches are used to secure the center panel to the inside and outside door skins. Air flow from the room is through the opening in the inside skin, around the outer perimeter of the panel, and outwardly from the door and room through the outside skin in a non-linear manner. Air flow is controlled by a plurality of movable panels disposed adjacent to the outer perimeter of the center panel. Sensor elements for sensing desired information and for providing output signals, including signals for actuating the movable panels, are included.
