Definitions

  • the invention relates to a railway wagon with heating or air conditioning, an air duct running below the lower edge of the compartment windows arranged in the wagon outer wall, from which supply ducts extend to outlet openings at the height of the lower window edges on the one hand and above the upper window edges on the other hand
  • supply ducts are delimited to the inside of the wagon by an intermediate wall which also covers at least part of the vertical region of the inside of the outside of the wagon above the air duct and also serves to cover window edges.
  • Such an arrangement is known, for example, from AT-B 355618 and, due to the outflow of the heated or air-conditioned air at the lower window edge on the one hand and above the upper window edge on the other hand, enables very uniform and draft-free heating or air conditioning of the wagon compartment.
  • the disadvantage here is that the installation of the intermediate wall delimiting the supply ducts to the inside of the wagon is relatively complex, since for a sufficient seal against the inside of the outside of the wagon or against the window edges as well as for maintaining the required distance from this inside to ensure the necessary Cross sections for the air flow must be provided.
  • the object of the present invention is to achieve an improvement of the known arrangement, while maintaining the advantages of the known arrangement with regard to the distribution of the inflowing air into the compartment, in such a way that in particular the assembly of the entire arrangement is simplified and a low-noise, optically simple means attractive, closed construction is achieved in particular with regard to the air duct.
  • the intermediate wall is designed as a compartment-side boundary of a hollow frame which contains the supply channels and is connected to transfer openings of the air guide channel.
  • the supply ducts to the outflow openings are thus formed in the hollow frame independently of the inside of the wagon outer wall, so that this only has to be attached to this inside in a very simple manner when the railway wagons are assembled; there are no more requirements with regard to sealing or maintaining a precise distance, which - while ensuring the optimal function - simplifies assembly work.
  • air guiding devices for the flow separation of the supply channels are arranged in the interior of the hollow frame. These air guiding devices can therefore already be provided in this frame, for example in the course of its manufacture, even before the hollow frame is installed in the railway wagon, which does not further burden the assembly work in the railway wagon.
  • the air guiding devices are adjustable, e.g. have control devices, in particular flaps, which can be influenced by the regulation of the heating or air conditioning system and which control the free flow cross sections of the supply channels in the hollow frame.
  • flaps can be designed, for example, so that once the frame has been installed in the railroad car, they are adjusted once with a view to optimal outflow conditions from the various outflow openings and are no longer adjusted during operation of the heating or air conditioning system. It would also be advantageous to provide an adjustment of these control devices by regulating the heating or air conditioning system.
  • the outflow openings arranged at the lower edge of the window which are primarily intended to prevent the windows from fogging up in heating mode, could be closed by closing off the associated supply ducts in cooling mode.
  • the hollow frame is made in one piece and can be attached to the inside of the wagon outer wall, since the assembly work is thus limited to setting up and fastening a single component on the inside of the wagon outer wall.
  • the frame can be designed as a plastic injection-molded part, which on the one hand enables cost-effective production and on the other hand also brings advantages in connection with thermal insulation and sound insulation.
  • the hollow frame is sealed off from the outside of the wagon by means of a seal which also serves to hold and seal the window. All that needs to be done is to attach, connect and seal the frame containing the preassembled window as a preassembled component during the final assembly of the wagon at a corresponding point on the inside of the outer wall.
  • the hollow frame consists of several parts, each of which forms a separate feed channel leading to an outflow opening or a group of outflow openings.
  • each of the outflow openings provided to have its own adjoining frame parts, the manufacture of which is simplified compared to a single component which covers the entire compartment wall, and which is nevertheless from the compartment seen form a single, practically continuous partition wall to the inside of the compartment.
  • a further embodiment of the invention provides that the hollow frame forms a preassembled structural unit together with at least part of the air duct running in the compartment. This simplifies the assembly of the parts of the air duct in each compartment in a very simple manner, since the actual air duct can be preassembled with the hollow frame containing the inlet ducts and thus only the connections to the other parts of the air duct during the actual assembly in the compartment Heating or air conditioning must be manufactured.
  • the structural unit in the area of the air duct has connection parts on both sides which, in the installed state, seal in the compartment against connection openings provided there.
  • connection parts on both sides which, in the installed state, seal in the compartment against connection openings provided there.
  • seals, fastening devices such as screws, fastening brackets or the like
  • other additional parts which enable assembly and provide a secure seal can be attached.
  • the structural unit is designed as a one-piece plastic injection-molded part. This eliminates the need for pre-assembly, and due to the lightness and the heat-insulating properties of plastic, there are further advantages.
  • the compartment 1 shown in FIG. 1 of a railway wagon, not shown, is connected via an air duct 2 to a heating or air conditioning system, also not shown, which is usually arranged, for example, below the wagon floor and supplies heated or conditioned air to the compartment 1.
  • a heating or air conditioning system also not shown, which is usually arranged, for example, below the wagon floor and supplies heated or conditioned air to the compartment 1.
  • the air duct 2 is arranged below the lower edge 3 of a window 5 embedded in the outer wall 4 of the wagon along the window-side compartment wall, and is via supply ducts 6, 7, 8 with outflow openings 9, 10 at the height of the lower window edge 3 on the one hand and above the upper one Window edge 11 connected on the other hand.
  • the supply ducts 6, 7, 8 are delimited to the inside of the wagon by an intermediate wall 14 which also serves to cover the window edges 3, 11, 12, 13 and covers at least part of the vertical area of the inside of the wagon outer wall 4 above the air duct 2, which serves as a compartment Boundary of a hollow frame 15 is formed, which receives the supply channels 6, 7, 8 and is connected to transfer openings 16 (Fig.2) of the air duct 2.
  • This hollow frame has air guiding devices 17 for the flow separation of the supply ducts 6, 7, 8, the free flow cross sections being able to be controlled via adjustable flaps 18 or similar control devices and being adjusted, for example, depending on the regulation of the heating or air conditioning system.
  • the feed channels 6 ', 7', 8 ' are also towards the inside of the wagon from at least part of the vertical also serving to cover the window edges Limited area of the inside of the outer wall 4 of the wagon above the intermediate wall 14 covering the air duct 2, which is designed as a compartment-side boundary of a hollow frame 15 which forms a preassembled unit 32 with the air duct.
  • the hollow frame 15 can also have air guiding devices 17 'for the flow separation of the supply ducts 6 ' , 7 ', 8 ' , adjustable flaps 18 'or similar control devices also being provided.
  • the structural unit 32 is in one piece, for example as a plastic injection-molded part, and also has the outflow openings 9 on the lower window edge and not shown here, those on the upper window edge and the lateral window edges.
  • the structural unit 32 is divided into a hollow frame 15 and air duct 2, it is also possible to manufacture the individual components from suitable materials, for example sheet metal on the one hand and plastic on the other hand.
  • connection parts 33 on both sides, which in the installed state of the assembly in compartment 1 against it - for example in the form of connecting pieces or the like. Seal the intended connection openings 34. Any seals, fasteners, etc. to be provided during assembly are not shown.
  • the hollow frame 15 or the structural unit 32 are made in one piece, for example as injection-molded plastic parts, and also have the outflow openings 9 (lower window edge) and 10 (upper window edge). It is also possible to design the frame as a pressed sheet metal part and to provide it with a preferably noise or heat-insulating coating at least on the inside of the compartment. In addition to this, in both cases, outflow openings could also be provided in the area of the lateral window edges 12, 13, each of which would be aligned with the opposite window edge, since, owing to the relatively large cross-section of the supply ducts available, only low flow velocities have to be provided and therefore no annoyance to the respective ones at the window seat opposite to seated travelers is to be feared. Additional air guidance devices or control devices could also be provided for these outflow openings, if necessary.
  • the hollow frame 15 can have an inlet opening 19 for the supply of compartment air in the area of the supply duct 7 to the outflow opening 9 at the lower window edge 3.
  • the arrangement of these inlet openings 19 does not make the formation of the hollow frame 15 much more complicated and the warm air present in the compartment can also be used to keep the window 5 free of fogging. It can be advantageous if an additional heating element is arranged in the frame in the area of the inlet opening 19 and is used to heat the mixed air to be supplied to the window 5.
  • FIG. 1 and FIG. 1a 20 denotes a ceiling light
  • 21 the luggage rack 22 the seats
  • 23 the storage tables 23 the storage tables
  • 24 a waste container 25 and 26 the compartment side walls are.
  • FIG. 5 a possibility is shown of having the supply channels 6 and 8 open into an overflow opening 28 in the region of the upper edge 27 of the hollow frame 15, which leads the supplied air behind the inner skin 29 of the curved wagon roof 30, from where it can exit through outflow openings 31.
  • a further improvement in the distribution of the heated or conditioned air in the compartment can be achieved under certain circumstances.
