- the housing 2 comprises an air outlet 'aeration' before 5a of the housing.
- the flow of air exiting through the air outlet 'ventilation' before 5a is intended to be distributed in the upper part of the front zone of the passenger compartment of the vehicle. It usually opens into the passenger compartment by aerators arranged on the dashboard.
- the housing 2 also has an air outlet 'foot' before 5b left and right. The flow of air exiting through the air outlet 'foot' before 5b is intended to be distributed in the lower part of the front zone of the passenger compartment of the vehicle. It usually opens into the passenger compartment by a mouth arranged on the lower part of the central console or the like.
- the housing 2 also includes a rear air outlet 'foot' rear 5c left and right. The air flow exiting through the rear 'foot' air outlet 5c is intended to be distributed in the lower part of the rear area of the passenger compartment of the vehicle.
- the housing 2 comprises a front 'defrost' air outlet intended to be distributed in an area arranged in the lower part of the windshield of the vehicle.
- the housing 2 From the air intake 4 and in the direction of flow of the air stream 6, the housing 2 delimits a volute portion 14 of the blower 3 and an air intake channel 13.
- the blower 3 is housed between the air inlet 4 and the air intake channel 13 in the volute defined on the one hand by the housing 2 and on the other hand by a suction ferrule 16 of the installation 1.
- the blower 3 comprises an electric motor 17 which rotates a wheel 18 provided with radial blades thus making it possible to suck up an air flow 6 coming from the passenger compartment, this air flow 6 passing through the air inlet 4.
- the air then accesses the wheel 18 through the suction ferrule 16.
- the suction ferrule 16 has the shape of a ring arranged vis-à-vis the wheel 18 and whose diameter allows to calibrate the incoming airflow.
- the suction ferrule 16 is an element of the volute distinct from the volute portion 14 formed by the housing 2 to close a housing cutout necessary for demolding the inner shapes of the housing 2.
- the air flow 6 thus sucked is accelerated by the wheel 18 in the direction of the arrows 6 shown in FIG. 4.

This reduces manufacturing costs by reducing the number of components of the installation 1.
- the suction ferrule element 22 shown in FIG. 6 comprising the suction ferrule 16 and the tubing cover 21 in one piece is for example made of plastic material.
- the ferrule element 22 can be obtained by molding.
- the pipe cover 21 has for example a plate shape.
- the transverse return 23 of the ferrule element 22, also in the form of a plate, makes it possible to close a hole in the housing 2, necessary for mounting the evaporator 7 and its pipes 19 to the expander 20.
