Abstract: An HVAC system provides airflow in a vehicle having a plurality of seating locations in a passenger cabin for respective passengers of the vehicle. The system includes a plurality of outlet vents and a plurality of suction returns disposed at various air return locations adjacent to the seating locations within the vehicle. An air handling unit is in fluid communication between the suction returns and the outlet vents. A plurality of flow control elements are provided, each one in series with at least one respective suction return for selectably modifying a respective flow of the respective suction return in response to a respective flow command. An occupancy determining apparatus identifies one or more seating locations for receiving enhanced airflow. A controller generates the respective flow commands in response to the identified seating locations.

Abstract: A cooling system for an automotive vehicle is disclosed including a heat exchanger assembly, a rotatable axial flow fan and a shroud member at least partially surrounding the fan and the heat exchanger assembly. The cooling system further includes a first ejector disposed between the heat exchanger and the engine and a pair of second ejectors disposed on the inner fender members of the vehicle for drawing ambient air from under the heat exchanger and pumping the air toward the engine and for preventing recirculation of the air exiting the shroud member back to the fan while the vehicle is at idle.
