Definitions

  • the present invention relates to an air conditioning device for vehicles, in particular for railway cars.
  • French patent 2,461,606 describes an air conditioning installation for railway cars comprising a fan blowing cold air or heated air in a duct extending to the lower part of the interior lateral face of the car. This duct opens into ducts to distribute the cold or heated air up the interior side of the car and down from the latter.
  • These distribution sheaths comprise in an intermediate zone an opening through which the air contained in the car is sucked inside the aforementioned distribution sheaths.
  • the installation comprises along each side wall of the car a succession of vertical air distribution ducts up and down.
  • the duct comprises at the right of each sheath an air outlet opening, provided with means for adjusting the flow of this air.
  • the air exiting from these openings is directed substantially parallel to the floor of the car and practically at the level of the feet of the user.
  • This air conditioning installation has a number of drawbacks.
  • the air opens inside of them by openings separated from each other which do not allow a regular and homogeneous mixing of the air.
  • the object of the present invention is to remedy the drawbacks of the installation known above, by proposing an air conditioning device which is better suited to modern non-compartmentalized railway cars and which makes it possible to obtain regular and homogeneous mixing of the air ensuring optimal comfort for travelers.
  • the air conditioning device targeted by the invention comprises at least one fan blowing cold air or heated air in a duct extending to the lower part of the interior lateral face of the vehicle, this duct opening into means for distributing the cold or heated air upwards and downwards from said inner lateral face, said distribution means comprising in an intermediate zone an opening through which the air contained in the vehicle is drawn inside said distribution means .
  • this device is characterized in that the above-mentioned conduit opens at its upper part into a space delimited by two parallel walls adjacent to the lateral face of the vehicle and extending without discontinuity over the entire length of the vehicle, this space opening at its upper part inside the vehicle by openings located substantially at the level of the windows of the vehicle, in that the duct has on its side face adjacent to the interior of the vehicle an air outlet passage extending substantially all over length of the vehicle and in that the wall adjacent to the interior of the vehicle of the aforementioned space has near the duct a slot extending over substantially the entire length of the vehicle by which the air contained in the vehicle is sucked into the above space.
  • the air distribution space extends over substantially the entire length of the vehicle allows the device according to the invention to adapt perfectly to the continuity of the lateral face of the vehicle, in particular of a car non-compartmentalized railway.
  • the vehicle can for example be equipped with seats spaced from each other by any distance which is entirely independent of the presence of the air conditioning device.
  • the air leaving the device is diffused inside the vehicle at a uniform temperature and flow.
  • the lateral wall of the duct has at its upper part air outlet openings which open into a compartment which opens downwards through a slot extending continuously over substantially all of the length of the vehicle.
  • this slit directs the cold air downwards, that is to say towards the floor, this air does not directly meet the feet of the travelers, so that they are not obstructed by the air coming out at the bottom of the device.
  • the device according to the invention makes it possible to perform an air mixing in the form of superimposed continuous rollers, one of these rollers being formed by the air emerging at the bottom of the device by a continuous slit and returning from it by the slit extending at the base of the space formed by the two parallel walls and the other roller being formed by the air exiting from the top of the device and returning therein through the aforementioned slot.
  • the continuity of these rollers allows efficient mixing of the air, which affects the entire interior volume of the vehicle.
  • the air conditioning device comprises a fan 1 disposed under the floor 3 of the railway car 2, blowing cold air or heated in a duct 4 extending to the lower part of the inner side face 5 of the car 2.
  • This duct 4 opens into means for distributing the cold or heated air upwards from the inner side face 5 and downwards from the latter.
  • These distribution means comprise in an intermediate zone an opening 6 through which the air contained in the car 2 is sucked inside these distribution means.
  • the duct 4 opens at its upper part into a space 7 delimited by two parallel walls 8, 9 adjacent to the lateral face 5 of the car 2 and extending without discontinuity over the entire length of this car.
  • the space 7 opens at its upper part inside the car, by elongated openings 10 located substantially at the lower edge of the windows 11 of the car.
  • the duct 4 has (see FIG. 2), on its lateral face 12 adjacent to the interior of the car, an air outlet passage 13 extending over the entire length of the car.
  • the wall 9 adjacent to the interior of the car in the aforementioned space 7 has, near the duct 4, a slot 6 extending over the entire length of the car by which the air contained in this car is drawn in. space 7 above.
  • the side wall 12 of the duct 4 has, at its upper part, air outlet openings 15 of small cross section constituting ejectors which open into a compartment 16 which opens towards the bottom by a slot 13 extending continuously over the entire length of the car 2.
  • the duct 4 has on its upper face 17 adjacent to the space 7 openings 18 of small section, constituting ejectors which open into the space 7.
  • the upper part of the duct 4 has a zone 19 delimited by walls 20, 21 which converge upwards, the top 17 of this zone having the openings 18 which open into the space 7.
  • the slot 6 through which the air contained in the car 2 is sucked into the aforementioned space 7 is situated substantially in line with the air outlet openings 18 which open into this space 7.
  • an electrical auxiliary heating resistor 22 is disposed slightly upstream of the openings 18 which open into the space 7. This resistor 22 is fixed against the wall 21 of the converging zone 19.
  • the openings 10 in the space 7 which open out substantially at the level of the windows 11 and the slot 13 in the duct 4 which opens downwards, comprise orientable strips 23, 24 for adjusting the direction of air outlet. .
  • the compartment 16 located downstream of the outlet openings 15 and upstream of the slot 13 has an outer wall connected to the upper wall 25 of the duct 4 by a rounded part 26 which guides the air towards the slot 13.
  • the side wall 12 of the duct 4 has at its lower part a rounded area 27 which laterally deflects the air towards the interior of the car.
  • the hot or cold air is blown at a flow rate adjustable as required, by the fan 1 in the duct 4 which extends to the lower part of the side face 5 of the car. From this duct 4, the air is blown upwards by the ejectors 18 and downwards from the car by the ejectors 15.
  • the air contained in the car is sucked into space 7 by the slot 6.
  • the air exiting through the openings 10 is constituted by a mixture of air coming from duct 4 and from inside the car.
  • the two continuous walls 8 and 9 delimiting the space 7 provide the interior lateral face 5 of the car with additional thermal and acoustic insulation.
  • the electrical resistance 22 placed in the zone 19 makes it possible, if necessary, to heat the air which is blown into the space 7.
  • the lower duct 4 of the device can be extended towards the interior of the vehicle so that its upper face constitutes the floor of the vehicle on which the seats can be fixed directly.
  • the ejection orifices 15 formed on the vertical wall 12 of the conduit 12 could be formed on a wall perpendicular to the latter extending in the space 16.
  • the ejection orifices 18 formed in the wall 17 situated at the base of the vertical compartment 7 could be closer to each other at the level of the windows 11 than elsewhere, to allow a flow of hot air or more cold at the windows and thus compensate for the greater heat losses at their level than elsewhere.
