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

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.
