    专利说明:

    [0001] The present invention relates to an air conditioning device for a railway vehicle comprising at least two cars. For example, this air conditioning device is intended to equip a tram, a subway or a regional train. Already known in the state of the art, an air conditioning device of at least two adjacent cars of a railway vehicle, including means for transmitting an air conditioning flow and a circulation network of the air conditioning, able to circulate the air conditioning from the means of emission to the rooms in the cars. Usually, the circulation network comprises at least one air-conditioning distribution duct extending over all the cars that are air-conditioned by this device. This distribution duct has several parts aligned in a predetermined order, each part being arranged in a separate car. In other words, the cars must also be aligned in a predetermined order. Thus, it is difficult to change the configuration of the railway vehicle, since the addition, removal or replacement of cars requires a complete rearrangement of the air conditioning device.
    [0002] The invention is intended to overcome this disadvantage, providing a modular air conditioning device, easily to change the configuration of the railway vehicle. For this purpose, the invention particularly relates to an air conditioning device of at least two adjacent cars of a railway vehicle, comprising means for transmitting an air conditioning flow and a circulation network of the air conditioning, characterized in that the circulation network comprises at least a first air conditioning circulation circuit intended to equip a first car, said first circulation circuit comprising: a first air-conditioned air intake, through which passes an air flow coming from the emission means, - at least a first air-conditioning distribution duct towards a room of said first car, extending from an upstream end, communicating with the air intake, to a closed downstream end, the upstream and downstream ends being both intended to be arranged in said first car, - at least a first air conditioning transfer duct to a second an adjacent air-conditioning circulation circuit, said second circulation circuit being intended to equip a second car adjacent to the first one, - first air-conditioning distribution means coming from the air intake, suitable for distributing the flow air entering between the distribution and transfer pipes. According to the invention, each car has a complete distribution duct of its own. Thus, the distribution ducts of two adjacent cars are independent. In other words, the structure of the first circulation circuit does not depend on the configuration of the railway vehicle, since this structure is limited to said first car. Thus, the addition or removal of a car does not impact the structure of the first traffic circuit. It is also possible to align several cars each equipped with a similar circulation circuit to said first circuit, each circuit being structurally independent of the others. The air conditioning device according to the invention is therefore modular, so that it is possible to modify the configuration of the rail vehicle without making any major structural modification of the air conditioning device. An air conditioning device according to the invention may further comprise one or more of the following characteristics, taken alone or in any technically feasible combination. - Each first distribution duct comprises an air-conditioned outlet, comprising at least one air outlet orifice, the conditioned air outlet extending along the first distribution duct, and each first distribution duct has a cross section variable, decreasing from the upstream end to the downstream end. - The first circulation circuit comprises a first central transfer duct, and two first lateral distribution ducts arranged laterally on either side of the first transfer duct. - The circulation network comprises a second circulation circuit, intended to equip a second car comprising: - a second air-conditioned intake, through which passes a flow of incoming air from the first air transfer duct, and - At least a first air-conditioning distribution duct to a room of said second car, the entire inflow of incoming air being distributed among the second or the second distribution ducts. - The circulation network comprises a deflector, arranged downstream of the air flow emitting means, separating the air flow from the emission means into a first air flow directed to said first circuit, and a second air flow directed to a third air circulation circuit. - Said third air circulation circuit is intended to equip a third car, and comprises: - a third air-conditioned air intake, through which a flow of incoming air from the emission means, - at least one third air-conditioning distribution duct to a room of said third car, - at least a third air-conditioning transfer duct to a fourth adjacent air-conditioning circulation circuit, and - third air distribution means conditioned air from the third air inlet, adapted to distribute the incoming air flow between the third distribution ducts and transfer. The invention also relates to a railway vehicle, comprising at least two adjacent cars, characterized in that it comprises an air conditioning device as defined above. Advantageously, a railway vehicle according to the invention may comprise one or the other of the following characteristics, taken alone or in combination. - The vehicle comprises a first car, in which is arranged the first traffic circuit, and a second car, adjacent to the first car, in which is arranged the second traffic circuit. - The vehicle has a third car, adjacent to the first car, in which is arranged said third traffic circuit. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, in which: FIG. 1 is a view from above of a railway vehicle; viewed from above by partial transparency, equipped with an air conditioning device according to an exemplary embodiment of the invention; FIG. 2 diagrammatically represents the air conditioning device equipping the railway vehicle of FIG. 1. FIG. 1 shows a railway vehicle 12, and more particularly, several cars of this railway vehicle 12 are represented, namely a first car 14, a second car 16, for example a driving car, adjacent to said first car and a third car 18 adjacent to the first car 14, and a fourth car 20 adjacent to the third car 18. The fourth car 20 is partially shown in Figure 1, this fourth car 20 being cut by a central transverse plane P.
    [0003] The railway vehicle 12 is equipped with an air conditioning device 10 for air conditioning the first 14, second 16 and third 18 cars, and a half of the fourth car 20, which is the half shown in FIG. rail vehicle 12 may for example comprise other cars not shown, air-conditioned by means of another air conditioning device arranged symmetrically to that shown in Figure 1, the symmetry being considered with respect to the plane P. Each car 14, 16, 18, 20 comprises at least one room, for example a passenger room, or a machine room. Advantageously, the rooms of these cars communicate with each other.
    [0004] The air conditioning device 10, shown in more detail in FIG. 2, comprises means 22 for emitting an air-conditioned flow, and a network 24 for circulating air-conditioning, conveying the air-conditioned air from the transmission means 22 to the rooms of the various cars of the railway vehicle 12. In accordance with the embodiment described, the transmission means 22 are arranged on the first car 14. The circulation network 24 comprises a deflector 26 of conventional type , arranged downstream of the air flow emitting means 22, and also arranged on the first car 14. This deflector 26 is intended to separate the air flow from the emitting means 22, into a first flow of air. air directed to a first circuit 28 for circulating air conditioning and a second air flow directed to another air circulation circuit 30. More particularly, said first circuit 28 equips the first car 14, and said other circuit 3 0 equips the third car 18. The first circulation circuit 28 comprises a supply of air conditioning 32, through which passes a flow of incoming air from the emission means 22, and more particularly, in the example described, corresponding to said first flow of air from the deflector 26. The first circulation circuit 28 further comprises at least a first duct 34 for distribution of conditioned air, for distributing the air conditioning to the room of the first car 14. Each first air distribution duct 34 extends from an upstream end 34A, communicating with the air inlet 32, to a closed downstream end 34B. These upstream ends 34A and downstream 34B are both arranged in the car 14. Thus, the first duct 34 extends completely into the first car 14, and its structure therefore does not depend on the cars adjacent to this first car 14. Each first dispensing duct 34 comprises an air conditioning outlet, comprising at least one air outlet orifice, the conditioned air outlet extending along the first distribution duct 34. For example, the air outlet comprises a slot or several parallel slots extending along the first distribution duct 34, or a plurality of orifices, aligned along the first distribution duct 34. The first circulation circuit 28 also comprises a first transfer duct 35. air conditioning to a second circuit 36 adjacent air conditioning circulation.
    [0005] This second circulation circuit 36 equips the second car 16 adjacent to the first car 14. In the example described, the first transfer conduit 35 is arranged centrally on the first car 14. The first circulation circuit 28 then comprises two first lateral distribution ducts 34 arranged laterally on either side of the first transfer duct 35. For example, the first central transfer duct 35 is separated from the first lateral distribution ducts 34 by partitions 38, for example metal partitions. The first circulation circuit 28 finally comprises first air conditioning distribution means 40 coming from the air inlet 32, suitable for distributing this conditioned air between the first distribution ducts 34 and the first transfer duct 35. the entire incoming airflow is distributed between the first distribution and transfer ducts 34. More particularly, a rate B of the incoming airflow is directed towards the first distribution ducts 34, and a rate of 1 -13 of the incoming air flow is directed to the first transfer conduit 35. This rate 1-13 of incoming air flow is transmitted to the second air circulation circuit 36. The rate B is determined so as to obtain satisfactory amounts of conditioned air, irrespective of the configuration of the railway vehicle, especially when the first car 14 is adjacent to the second car 16, or when an intermediate car is interposed between the first car 16; oiture 14 and the second car 16. For example, for an air flow Q = 4200m3 / h, the B rate is chosen equal to 55%. Advantageously, each first distribution duct 34 has a variable cross section, and more particularly a cross section decreasing from the upstream end 34A to the downstream end 34B. This reduction in the cross section of the distribution duct 34 makes it possible to maintain a substantially constant air conditioning flow rate throughout the conditioned air outlet. Indeed, the volume of conditioned air decreasing along the distribution duct 34, because the conditioned air exits through the air outlet, it is necessary to reduce the cross section of the distribution duct to maintain the debit.
    [0006] In the example shown, the second circulation circuit 36 is an end circulation circuit, that is to say having no air conditioning transfer duct to another circuit. Indeed, the second car 16 is an end car, so that the air conditioning is not transmitted to another car.
    [0007] The second circulation circuit 36 comprises a second air-conditioned air intake 42 through which a flow of incoming air coming from the first air-transfer duct 35 passes and at least one second air-conditioning distribution duct 44 to a room of the corresponding car 16. For example, the second circuit 36 includes two second distribution ducts 44, each extending integrally in the second car 16. The entire air flow entering through the air-conditioned inlet 42 is distributed among the second ducts 44, by second distribution means 46. Each second distribution duct 44 has an air conditioning outlet extending along the second distribution duct 44, and advantageously has a variable cross section on at least a portion of its length. As mentioned previously, the conditioned air coming from the transmission means 22 is partially diverted towards the first circulation circuit 28, that is to say towards the first 14 and second 16 cars, and partly diverted towards another one. circuit 30, said third circuit 30.
    [0008] This third air circulation circuit 30 is intended to equip the third car 18, and is substantially similar to the first circulation circuit 28. In particular, it comprises: - a third air-conditioned air intake 48, through which passes a flow of incoming air from the emission means 22, and more particularly a portion of the air flow deflected by the deflector 26, - at least a third conduit 50 of air-conditioning distribution to a room of the third car 18, at least one third air-conditioning transfer duct 52 to a fourth adjacent conditioned air circulation circuit 54, and third air-conditioning distribution means 56 from the air inlet 48, adapted to distribute the incoming air flow between the third distribution conduits 50 and transfer 52. Similarly, said fourth circulation circuit 54 is intended to equip the fourth car 20, and it is for example similar e to the second circulation circuit 36.
    [0009] In particular, it comprises a fourth air intake 58, through which passes an incoming air flow from the third air transfer duct 52, and two fourth air distribution ducts 60 to a room of the air 20. The entire flow of incoming air is distributed among the fourth distribution ducts 60, by fourth distribution means 62. Advantageously, each of the first 40, second 46, third 56 and fourth distribution means 62. air comprise means for varying the distribution of air flows. Note that the invention is not limited to the embodiment described above, but could have various variants without departing from the scope of the claims. In particular, a different arrangement of the circulation circuits could be provided. For example, one could insert another car equipped with another similar circulation circuit to the first circulation circuit 28 between the first car 14 and the second car 12. Indeed, the invention allows a great modularity in the configuration of the vehicle Railway 12.15
