An air conditioner for a vehicle includes an air conditioning case and a case interior member in the air conditioning case. The case interior member includes a tunnel member and a tunnel exterior guide wall. The tunnel member defines a tunnel channel therein and is arranged in a downstream space defined in an air conditioning case. The tunnel exterior guide wall is configured to guide an air to flow from a warm air passage to an outside of the tunnel channel. A first direction along which the tunnel exterior guide wall extends is closer to a direction, which is opposite to the one direction along which the air flowing from a cool air passage into the downstream space, as compared to a second direction along which the tunnel guide wall extends.

An air conditioning unit for a vehicle includes: an air conditioning case, a blower that draws air from an opening and blows the air radially outward from its rotation axis, a cooler disposed upstream of the blower, and a heater is disposed downstream of the blower. The air conditioning case includes an upper bypass passage through which the air bypasses the heater on an upper side of the heater, a lower bypass passage through which the air bypasses the heater on a lower side of the heater, a first opening provided downstream of the upper bypass passage, and a second opening provided downstream of the lower bypass passage. The opening of the blower faces an air outflow face of the cooler. A passage area of the upper bypass passage is larger than a passage area of the lower bypass passage.

An HVAC system for a vehicle. The HVAC system including an evaporator case, a heater case, and a blower case. The heater case is in cooperation with the evaporator case to receive airflow from the evaporator case. The heater case includes a heat source and defines front passenger cabin airflow outlets and rear passenger cabin airflow outlets. The blower case is in fluid communication with the evaporator case and includes a single airflow generator that generates airflow through the evaporator case, through the heater case, and to both the front passenger cabin airflow outlets and the rear passenger cabin airflow outlets.

The invention relates to a motor vehicle heating, ventilation and/or air conditioning device (2) comprising a housing (4) comprising: a duct (14) for distributing a flow of air at foot level in the front of the said vehicle, a first (15) and a second (22) mixing chamber, a dividing flap (32) separating the said mixing chambers (15, 22).
