Abstract
An HVAC assembly for a vehicle. The HVAC assembly has an HVAC case with a rear blower and an evaporator. A rear blower scroll directs airflow generated by the rear blower to a lower portion of the evaporator. An airflow conduit is configured to direct airflow generated by a front blower to an upper portion of the evaporator. An airflow divider separates airflow generated by the rear blower from airflow generated by the front blower. The airflow divider divides the HVAC case into an upper area above the divider and a lower area below the divider. A defrost outlet and a front face outlet are at the upper area of the HVAC case above the divider. A front foot outlet and a rear airflow outlet are at the lower area of the HVAC case below the divider.
Claims16
A heating, ventilation, and air conditioning (HVAC) assembly for a vehicle, the HVAC assembly comprising:
- an HVAC case including:
- an evaporator;
- a rear blower including a rear blower scroll configured to direct airflow generated by the rear blower to a lower portion of the evaporator;
- an airflow conduit configured to direct airflow generated by a front blower to an upper portion of the evaporator;
- an airflow divider separating airflow generated by the rear blower from airflow generated by the front blower, the airflow divider divides the HVAC case into an upper area above the airflow divider and a lower area below the airflow divider;
- a defrost outlet and a front face outlet at the upper area of the HVAC case above the airflow divider;
- and
- a front foot outlet and a rear airflow outlet at the lower area of the HVAC case below the airflow divider;
- and
- a front blower case housing the front blower, the front blower case is connected to the HVAC case by the airflow conduit, the front blower is spaced apart from the rear blower;
- wherein the airflow divider is positioned such that all airflow exiting the HVAC case through the front foot outlet is recirculated passenger cabin airflow pushed through the front foot outlet by the rear blower.
A heating, ventilation, and air conditioning (HVAC) assembly for a vehicle, the HVAC assembly comprising:
- a front blower case including a front blower;
- and
- an HVAC case connected to the front blower case by an airflow conduit, the HVAC case including a rear blower that is spaced apart from the front blower, an evaporator, a front foot outlet, and an airflow divider separating airflow generated by the rear blower from airflow generated by the front blower, the airflow divider divides the HVAC case into an upper area above the airflow divider and a lower area below the airflow divider;
- wherein the front foot outlet is below the airflow divider;
- and
- wherein the airflow divider is positioned such that all airflow exiting the HVAC case through the front foot outlet is recirculated passenger cabin airflow pushed through the front foot outlet by the rear blower.
