Abstract
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.
