Claim 10:
11. An HVAC system, comprising:
an evaporator;
a heater;
a plurality of outlets;
a sliding control door downstream of the evaporator and configured to allow air to flow across one or both of a heated path across the heater and a bypass path bypassing the heater; and
a sliding stratification door downstream of the control door and positionable to, in an intermediate position, direct the air flowing through the bypass path to be mixed with air that flowed across the heated path before flowing out of the plurality of outlets;
wherein, in the intermediate position, the air flowing across the bypass path flows between a convex surface of the control door and a concave surface of the stratification door and toward a lower portion of a bypass cavity, where the air is then mixed with the air that flowed across the heated path.
