<p>A return air apparatus (10) is provided with a ceiling template (12), which is mounted to an air comfort appliance unit at the ceiling of a recreational vehicle, a down draft diverter (13), a return air cover (14), and a return air grille (17). The ceiling template (12) has a discharge opening (22) and a return opening (24) divided by an air barrier (11). The return air cover (14) has a direct discharge opening (40) and a return opening (42) positioned below the ceiling template openings (22, 24). The return air grille (17) has a first section that communicates with the discharge opening (22) of the ceiling template (12) and a predetermined area of the interior of the recreational vehicle, and a second section that communicates with the return opening (24) of the ceiling template (12) and the interior of the recreational vehicle. A down draft diverter (13) positioned in the air return cover (14) and over the direct discharge opening (40) of the air return cover (14) allows air to be discharged directly through the discharge opening of the return air grille by creating an opening between the down draft diverter and the ceiling template. <IMAGE></p> |
