A dual zone auxiliary climate control system for a vehicle includes an evaporator, a heater core having a first zone and a second zone, a first zone mode door downstream from the first zone of the heater core, a second zone mode door downstream from the second zone of the heater core and a blower. The blower forces air through the evaporator and the heater core toward the first zone mode door and the second zone mode door. A method of providing a dual zone auxiliary climate control system is also disclosed.

An air inlet system for an automotive HVAC system has a housing comprising a first cylindrical segment enclosing an interior space and having a first radial surface with a first angular divergence. The first radial surface has a fresh air aperture and a recirculation aperture for radially receiving fresh air and recirculated air, respectively. The housing further comprises an outlet body with an exit aperture. A pivoting door element is mounted in the interior space and shaped as a second cylindrical segment with a second radial surface with a second angular divergence which is less than the first angular divergence. The door element has a pivot axis that allows the second radial surface to slide along the first radial surface. The door element pivots to selectably align the opening with the fresh air aperture or the recirculation aperture in order to 1) block the fresh air aperture without blocking the recirculation aperture, 2) simultaneously block portions of the fresh air aperture and the recirculation aperture, 3) block the recirculation aperture without blocking any of the fresh air aperture, or 4) block the recirculation aperture while blocking only a portion of the fresh air aperture.

A plenum assembly for carrying air in a supply system includes a duct including an opening formed with an inner surface through which air can flow; a door supported for movement between multiple positions which distributes air to the desired output path; and a seal secured to the door. In a vehicles HVAC system, numerous doors are utilized to provide comfort to the passengers based upon user input. The potential exists that some positions of the doors my lead to unwanted noise. A modification to the seal of the door with variable gap widths alleviates this issue and improves satisfaction.

A dual fan blower module of the present invention includes a housing defining a central motor compartment and first and second scroll chambers. The scroll chambers are axially aligned with and located on opposite sides of the motor compartment. A motor is mounted within the motor compartment and has first and second shaft ends extending axially therefrom. The first shaft end extends into the first scroll chamber and the second shaft end extends into the second scroll chamber. A first fan is mounted onto the first shaft end within the first scroll chamber for rotational movement within the first scroll chamber and a second fan is mounted onto the second shaft end within the second scroll chamber for rotational movement within the second scroll chamber. Each of the first and second scroll chambers includes an expansion channel extending axially inward toward the motor.
