Abstract
A return air apparatus is provided with a ceiling template, which is mounted to an air comfort appliance unit at the ceiling of a recreational vehicle, a down draft diverter, a return air cover, and a return air grille. The ceiling template has a discharge opening and a return opening divided by an air barrier. The return air cover has a direct discharge opening and a return opening positioned below the ceiling template openings. The return air grille has a first section that communicates with the discharge opening of the ceiling template and a predetermined area of the interior of the recreational vehicle, and a second section that communicates with the return opening of the ceiling template and the interior of the recreational vehicle. A down draft diverter positioned in the air return cover and over the direct discharge opening of the air return cover allows air to be discharge directly through the discharge opening of the return air grille by creating an opening between the down draft diverter and the ceiling template.
