Abstract

An air-conditioning device has a duct that emits a flow of conditioned air and at least one circulation circuit intended for fitting out a carriage. The circulation circuit includes an air inlet through which passes an incoming airflow from the duct; at least one conduit for distributing air towards a compartment room, extending between an upstream end and a downstream end, both intended to be laid out in the carriage; a conduit for transferring conditioned air towards another adjacent air circulation circuit, which fits out a carriage adjacent to the first; and means for distributing conditioned air from the air inlet, and distributing the incoming airflow among the distribution and transfer conduits.

First claim

The invention claimed is:

1. An air conditioning device for air-conditioning at least two adjacent carriages of a railway vehicle, comprising an emitter of a conditioned air flow and a circulation network for circulating the conditioned air flow, wherein the circulation network includes at least one first circulation circuit for circulating conditioned air flow, intended to fit out a first carriage, said first circulation circuit including:
a first conditioned air inlet, through which passes an incoming airflow from the emitter,
at least one first distribution conduit for distributing conditioned air towards a first compartment room of said first carriage, extending from an upstream end, communicating with the first conditioned air inlet, as far as a closed downstream end, the upstream end and the downstream end being both intended for being laid out in said first carriage,
at least one first transfer conduit for transferring conditioned air towards an adjacent second conditioned air circulation circuit, said second conditioned air circulation circuit being intended to fit out a second carriage adjacent to the first carriage, wherein each transfer conduit only has a transfer function, and is therefore without any conditioned air outlet intended for a compartment room,
a first distributor for distributing conditioned air from the air inlet, able to distribute the incoming airflow among the first distribution conduit and the first transfer conduit.

2. The air-conditioning device according to claim 1 , wherein:
each first distribution conduit includes a conditioned air outlet, including at least one air outflow orifice, the conditioned air outlet extending along the first distribution conduit,
each first distribution conduit has a variable cross-section, decreasing from the upstream end to the downstream end.

3. The air-conditioning device according to claim 1 , wherein the first circulation circuit includes a first central transfer conduit, and two first lateral distribution conduits laid out laterally on either side of the first transfer conduit.

4. The air-conditioning device according to claim 1 , wherein the circulation network includes a second circulation circuit, intended for fitting out a second carriage, including:
a second conditioned air inlet, through which flows an incoming airflow from the first air transfer conduit,
at least one second distribution conduit for distributing conditioned air towards a second compartment room of said second carriage, the whole of the incoming airflow being distributed among the second distribution conduit(s).

5. The air-conditioning device according to claim 1 , wherein the circulation network includes a deflector, laid out downstream from the emitter emitting an airflow, separating the airflow from the emitter into a first airflow directed towards said first circulation circuit, and into a second airflow directed towards a third air circulation circuit.

6. The air-conditioning device according to claim 5 , wherein said third air circulation circuit is intended to fit out a third carriage, and includes:
a third conditioned air inlet, through which passes an incoming airflow from the emitter,
at least one third distribution conduit for distributing conditioned air towards a third compartment room of said third carriage,
at least one third transfer conduit for transferring conditioned air towards an adjacent fourth conditioned air circulation circuit,
a third distributor for distributing conditioned air from the third air inlet, able to distribute the incoming airflow among the third distribution conduit and the third transfer conduit.

7. A railway vehicle, including at least a first carriage and a second carriage adjacent to the first carriage, and including an air-conditioning device comprising an emitter of a conditioned air flow and a circulation network for circulating the conditioned air flow, wherein the circulation network includes at least one first circulation circuit for circulating conditioned air flow, fitting out the first carriage, said first circulation circuit including:
a first conditioned air inlet, through which passes an incoming airflow from the emitter,
at least one first distribution conduit for distributing conditioned air towards a first compartment room of said first carriage, extending from an upstream end, communicating with the first conditioned air inlet, as far as a closed downstream end, the upstream end and the downstream end being both intended for being laid out in said first carriage,
at least one first transfer conduit for transferring conditioned air towards an adjacent second conditioned air circulation circuit, said second conditioned air circulation circuit fitting out the second carriage,
a first distributor for distributing conditioned air from the air inlet, able to distribute the incoming airflow among the first distribution conduit and the first transfer conduit, the first distributor extending parallel to the first transfer conduit, and parallel to a longitudinal direction of the first carriage.

8. The railway vehicle according to claim 7 , wherein the circulation network includes a second circulation circuit, fitting out the second carriage, including:
a second conditioned air inlet, through which flows an incoming airflow from the first air transfer conduit,
at least one second distribution conduit for distributing conditioned air towards a second compartment room of said second carriage, the whole of the incoming airflow being distributed among the second distribution conduit(s).

9. The railway vehicle according to claim 8 , including a third carriage adjacent to the first carriage, and in which is laid out a third circulation circuit, wherein the circulation network includes a deflector, laid out downstream from the emitter emitting an airflow, separating the airflow from the emitter into a first airflow directed towards said first circulation circuit, and into a second airflow directed towards said third air circulation circuit.

10. The railway vehicle according to claim 9 , wherein said third air circulation includes:
a third conditioned air inlet, through which passes an incoming airflow from the emitter,
at least one third distribution conduit for distributing conditioned air towards a third compartment room of said third carriage,
at least one third transfer conduit for transferring conditioned air towards an adjacent fourth conditioned air circulation circuit,
a third distributor for distributing conditioned air from the third air inlet, able to distribute the incoming airflow among the third distribution conduit and the third transfer conduit.

11. The railway vehicle according to claim 8 , wherein:
each first distribution conduit includes a conditioned air outlet, including at least one air outflow orifice, the conditioned air outlet extending along the first distribution conduit,
each first distribution conduit has a variable cross-section, decreasing from the upstream end to the downstream end.

12. The railway vehicle according to claim 8 , wherein the first circulation circuit includes a first central transfer conduit, and two first lateral distribution conduits laid out laterally on either side of the first transfer conduit.
