Abstract
A heating, ventilating, and air conditioning (HVAC) assembly having a housing defining first and second quadrants. An air mixing door is mounted to the housing downstream of an inlet and upstream of an outlet. The air mixing door has a first position directing substantially all of the air through the first quadrant, a second position directing substantially all of the air through the second quadrant, and a third position directing a flow of air through both of the first and second quadrants. A first seal is mounted to a first side of the air mixing door and a second seal is mounted to a second side of the air mixing door. A diffuser is mounted to at least one of the sides of the air mixing door and has a plurality of passageways to interrupt a flow of air passing around the air mixing door when the air mixing door initially moves from one of the first and second positions to the third position, thereby controlling an initial flow of air into at least one of the quadrants.
