Abstract
A HVAC system is operable in a fresh air mode and a recirculation mode for use in a vehicle is disclosed. The HVAC system includes a blower and a HVAC module in fluid communication with and downstream of the blower for warming and cooling the air to be circulated through the passenger compartment in both the fresh air mode and the recirculation mode. The HVAC module includes an inlet duct in fluid communication with and upstream of the blower and located above the dashboard for drawing air from the passenger compartment above the dashboard and through the blower and the HVAC module in the recirculation mode. The inlet duct above the dashboard improves air circulation within the passenger compartment that improves the air warm-up rate. The inlet duct above the dashboard also improves the airflow across a windshield to prevent fogging of the windshield.
