Hvac inlet with ram air and partial recirculation function

A method of operating an air handling system of a vehicle comprising the steps of:

• providing a housing, an air distribution door, and a baffle door, the housing defining an inlet section, the inlet section including a recirculation inlet configured to receive recirculated air originating from a passenger compartment of the vehicle and a fresh air inlet configured to receive fresh air originating from an ambient environment, the air distribution door disposed in the inlet section and configured to control a distribution of the recirculated air and the fresh air entering the inlet section through the recirculation inlet and the fresh air inlet, the baffle door disposed in the inlet section;
• and
• adjusting a position of the baffle door to selectively reduce a flow area through the fresh air inlet to accommodate a ram air pressure induced by motion of the vehicle relative to the fresh air of the ambient environment.
