  • the second air intake 21 is, at least for part of its extension, inclined with respect to the longitudinal axis X, and hence with respect to the third conduit 22 and the fourth conduit 23.
  • one or more of, preferably both the first duct 10 and the second duct 20 have each a shaped body comprising a plurality of separate modules M1, M2, M3, M4 which are assembled together to form the respective first duct 10 and second duct 11.
  • the first duct 10 has a shaped body comprising a first central portion 16 which has, seen from a top view: a first side 17 at which there is provided the first air intake 11; an inclined second side 18, converging from one end of the first side 17 to a first side of the first conduit 12 extending in the first direction F1 along the longitudinal axis X; and a third side 19, opposite to the second side 18 with reference to the first air intake 11, which connects the first side 17 with a second side of the first conduit 12.
  • the third side 19 comprises two sections, e.g. a first section 19a constituted by an extension of the second side of the first conduit 12 towards the first air intake 11, and a second section 19b connecting the first section 19a with another end part of the first air intake 11.
  • the second conduit 13 extends from the first air intake 11 in the second opposite direction R1 along the longitudinal axis X, substantially aligned with the first conduit 12; in particular, in the embodiment illustrated, one side of the second conduit 13 extends directly from one end part on the first air intake 11, while on the opposite side of the second conduit 13, there is provided an inclined side 15 converging from and joining the first air intake 11 to the second conduit 13.
  • the second duct 20 has a shaped body comprising a second central portion 26 which has, seen from a top view: a first side 27 at which there is provided the second air intake 21; an inclined second side 28, converging from one end of the first side 27 to the fourth conduit 23 extending in the second direction R1 along the longitudinal axis X, substantially parallel to the second conduit 13; and a third side 29, opposite to the second side 28 with reference to the second air intake 21, which connects the first side 27 with the fourth conduit 23.
  • the third side 29 of the second duct 20 comprises two sections, e.g. a first section 29a constituted by an extension of the second side of the fourth conduit 23 towards the second air intake 21, and a second section 29b connecting the first section 29a with another end part of the second air intake 21.
  • the third conduit 22 extends from the second air intake 21 in the first opposite direction F1 along the longitudinal axis X, substantially aligned with the third conduit 21 and parallel to the first conduit 12; in particular, in the embodiment illustrated, one side of the third conduit 22 extends directly from one end part on the second air intake 21, while on the opposite side of the third conduit 22, there is provided an inclined side 25 converging from and joining the second air intake 21 to the third conduit 22 itself.
  • the first module M1 can comprise end parts of the respective first and third conduits 12 and 22
  • the modules M2 and M3 can comprise part of the respective air intakes 11 and 21, of the central portions 16, 26, and the initial parts of the respective first, second, third and fourth conduits 12, 13, 22 and 23, while the fourth module M4 can comprise end parts of the respective second and fourth conduits 13 and 23.
  • the air distribution system 1 can comprise an additional module M5, one example of which is schematically illustrated in figure 3 .
  • the additional module M5 extends substantially rectilinear along the longitudinal axis X, and it is intended to be positioned at a middle part of the respective central portion 16, 26 of the first duct 10 and/or of the second duct 20 and to be assembled with the adjacent modules M2 and M3 thereof.
  • the additional module M5 which can be easily and suitably sized as desired, comprises two channel sections 31 and 32 which, once the module M5 is assembled, are part of and contribute to form the respective central portions 16 and 26, thus allowing for example to properly modify the overall length of the ducts 10 and 20, and hence to adapt the air distribution system 1 to railway vehicles having different lengths.
  • the first duct 10 and the second duct 20 are substantially identical to each other, apart from unavoidable minor constructive mechanical tolerances or differences.
  • the first duct 10 and the second duct 20, with or without the additional module M5 can be positioned as illustrated for example in figure 1 shown without the additional module M5, side by side with the inclined second side 18 of the first central portion 16 adjacent to and in contact with the inclined second side 28 of the second central portion 26.
  • the first duct 10 and the second duct 20, with or without the additional module M5 can be positioned side by side with the inclined second side 18 of the first central portion 16 facing to and spaced apart from the inclined second side 28 of the second central portion 26.
  • the air distribution system 1 according to the present invention can be easily adapted also to vehicles, and in particular railway vehicles, having different widths.
  • the air distributing system 1 constitutes a kind of universal ducting system for being used in HVAC systems and/or with different types of vehicles.
  • HVAC Heating, Ventilation and Air Conditioning
  • the solution devised according to the present invention is particularly advantageous in case of pantograph-based railway vehicles, such as the one illustrated in figure 4 with two pantographs 101 mounted on the roof 102 of the railway vehicle 100.
  • a first HVAC unit 201 and a second HVAC unit 202 for generating the conditioned air to be distributed inside the vehicle 100 can be conveniently mounted on the roof 102 at a central part thereof between the two pantographs 101, with the air distribution system 1 installed for example with the first and second ducts 10, 20 below the roof 102 of the railway vehicle 100, e.g. in the space between the roof 102 and an internal ceiling of the internal compartment of the vehicle 100 itself.
  • the whole air distribution system 1 is formed by two sub-parts which can function together and both split the respective flow of conditioned air to be distributed in a forward direction and in a rearward direction. If one of the two subparts fails for whatever reason, the other one allows in any case to have a substantially uniform distribution of conditioned air inside the full length of the vehicle thanks to such splitting into the two opposite directions F1 and R1.
  • each of the two subparts has one channel which ends in correspondence of a cabin booster 50 and therefore can always guarantee the supply of treated air also inside the driver cab.
  • the two ducts 10 and 20 of the air distribution system 1 are positioned symmetrically to each other with respect to a vertical plan 60 parallel to the two lateral sides of the vehicle and virtually dividing longitudinally the vehicle in two equal parts, and the same occurs when considering the whole HVAC system 200 with the two HVAC units 201, thus contributing in better dynamics of the vehicle.
  • the air distribution system 1, the HVAC system 200, and the related vehicle 100 achieve the intended aim and objects, since they allow a proper conditioning of the interior of a vehicle, including the driver cabin, even when there is a failure, and according to a solution which can be utilized with vehicles of different sizes with very minor constructive modifications of even without any modification.
  • the air distribution system 1, the HVAC system 200, and the related vehicle 100 thus conceived are susceptible of modifications and variations, all of which are within the scope of the inventive concept as defined in particular by the appended claims; for example, one or more components or any part thereof may be differently shaped with respect to what previously described; each module, such as for example the module M5 previously described, can be realized as a unique piece, or by two or more submodules which can be assembled to or disassembled from each other.
