An air handling system a housing defining an inlet section which includes a first inlet portion and a second inlet portion. The first inlet portion includes a first recirculation inlet receiving recirculated air from a passenger compartment of the vehicle and a first ambient air inlet receiving ambient air from the environment. The second inlet portion includes a second recirculation inlet receiving recirculated air from the passenger compartment of the vehicle and a second ambient air inlet receiving the ambient air from the environment. A first air distribution door and a first baffle door are disposed in the inlet section to selectively control distribution of the recirculated air and the ambient air entering the first inlet portion. A second air distribution door and a second baffle door are disposed in the inlet section to selectively control distribution of the recirculated air and the ambient air entering the second inlet portion.

HVAC dual inlet design for partial recirculation operation

An air-handling system for a heating, ventilation, and air conditioning system of a vehicle includes a main housing comprising a conditioning section, a mixing section, and a delivery section having a flow of air passing therethrough. The delivery section includes a conduit branching into a windshield defrost pathway and a demist pathway, the windshield defrost pathway leading to windshield defrost vents of a passenger compartment of the vehicle and the demist pathway leading to side window defrost vents of the passenger compartment. A control door rotatably disposed in the conduit is adjustable through a range of rotational positions wherein a flow area through the windshield defrost pathway is variably restricted while the demist pathway remains unobstructed. The control door is further adjustable to a position wherein the windshield defrost pathway and the demist pathway are closed.
