Abstract

The invention concerns a heating/air conditioning installation for the passenger compartment of a vehicle.

It comprises treatment means produced in the form of at least one removable box suitable for being installed underneath the floor of the vehicle and containing an air inlet, an optional evaporator, a heating radiator and at least one air outlet suitable for being connected to distribution vents distributed within the passenger compartment.

Claims

1. A main heating/air conditioning installation for the passenger compartment of a vehicle, comprising treatment means for producing treated air and distribution pipes connected to the treatment means in order to channel the treated air to distribution vents distributed within the passenger compartment, wherein the treatment means comprise at least one removable box capable of being removed from the vehicle for being installed under the floor of the vehicle, the removable box comprising a heating radiator, an air inlet and at least two air outlets, one of said air outlets being connected to a pipe leading to distribution vents positioned on a fascia and another of said air outlets leading to a pipe connected to a hollow side member, and wherein the distribution pipes are formed at least partially by hollow elements of the frame of the vehicle, which comprises the side member.

2. Installation according to claim 1, wherein the at least one removable box is mounted vertically from underneath the floor and further including a rapid fixing means.

3. Installation according to one of claims 1 and 2, comprising two removable boxes disposed respectively on the right-hand side and left-hand side of the vehicle and sending treated air respectively in the right-hand part and left-hand part of the passenger compartment.

4. Installation according to claim 3, wherein the respective air inlets of the two removable boxes are connected to a common admission pipe suitable for being supplied with air from the outside.

5. Installation according to claim 1, wherein an evaporator in the box is connected to a refrigeration circuit also housed in the box.

6. Installation according to claim 1, wherein the air inlet of the box is provided with a rapid coupling for being connected to an air admission pipe and wherein the air outlets are each provided with a rapid coupling for being connected to the distribution pipes.

7. Installation according to claim 1, wherein the at least one removable box is mounted horizontally from the side in the manner of a drawer and further including a rapid fixing means.

8. Installation according to claim 3, wherein the respective air inlets of the two removable boxes are connected to a common admission pipe for being supplied with recycled air.

9. A heating/air conditioning installation for the passenger compartment of a vehicle, comprising treatment means for producing treated air and distribution pipes connected to the treatment means in order to channel the treated air to distribution vents distributed within the passenger compartment, wherein the treatment means comprise at least one removable box capable of being removed from the vehicle for being installed under the floor of the vehicle and containing an air inlet, a heating radiator and at least two air outlets, one of said air outlets being connected to a hollow side member of the frame of the vehicle and another of said air outlets being connected to the distribution vents on a fascia, and wherein the distribution pipes are formed at least partially by hollow elements of the frame of the vehicle.
