Heating, ventilation and/or air-conditioning device for a motor vehicle

1 . A heating, ventilation and/or air-conditioning (HVAC) device for a motor vehicle, the HVAC device comprising:

a housing of elongate shape comprising a lower surface defining a flow channel for an air flow;

a first heat exchanger:

arranged in the flow channel, and

inscribed in a first plane;

a second heat exchanger:

arranged in the flow channel, and

inscribed in a second plane;

wherein an angle between the first plane and the second plane is between 90° and 120°;

a bypass path of the second heat exchanger;

a first air outlet duct, a second air outlet duct, and a third air outlet duct, wherein each one of the air outlet ducts is configured to guide the air flow toward different regions of a vehicle passenger compartment;

a single mixing flap comprising a single sliding door, wherein the single mixing flap is arranged in the flow channel and downstream of the first heat exchanger and second heat exchanger;

wherein the single mixing flap is configured to:

translate the single sliding door between a first end position and a second end position,

close the bypass path, that is confined by the first heat exchanger, while the single sliding door is at the first end position, and

close the second heat exchanger while the single sliding door is at the second end position;

a second distribution flap comprising a sliding door configured to:

translate between a first end position and a second end position,

close an inlet mouth of the second air outlet duct while the sliding door is at the first end position, and

allow a flow of cold air from a mixing chamber while the sliding door is at the second end position;

wherein the third air outlet duct comprises an inlet mouth arranged at a level of the mixing chamber in which hot and cold air are mixed;

wherein a blower, the first heat exchanger, and the second heat exchanger are aligned in a transverse axis of said housing;

wherein the first heat exchanger and the second heat exchanger are aligned in a longitudinal axis of said housing;

wherein the lower surface of the housing defines the flow channel and the third air outlet duct; and

wherein the third air outlet duct is further defined by an external wall and directs the air flow from the mixing chamber to a bulkhead of the motor vehicle, and

wherein the single sliding door is substantially parallel to the second heat exchanger at the second end position.

2 . The HVAC device as claimed in claim 1 , wherein the second distribution flap is configured to guide the air flow toward a ventilation nozzle.

3 . The HVAC device as claimed in claim 1 , further comprising a first distribution flap comprising a flag-type flap configured to at least partially close the first air outlet duct.

4 . The HVAC device as claimed in claim 3 , wherein the third air outlet duct is configured to guide an air flow toward a feet nozzle.

5 . The HVAC device as claimed in claim 1 , further comprising a third distribution flap comprising a butterfly-type flap configured to at least partially close the third air outlet duct.

6 . The HVAC device as claimed in claim 5 , wherein the first air outlet duct is configured to guide an air flow toward a defrost nozzle.

7 . The HVAC device as claimed in claim 1 , wherein the second heat exchanger is substantially horizontal in the vehicle.

8 . The HVAC device as claimed in claim 1 , wherein the housing comprises an outside air inlet and a recycling air inlet.
