Definitions

  • the present invention relates to an air extraction device for conditioning the atmosphere of a railway vehicle and temporary pressurization (or overpressure) of this atmosphere.
  • the object of the present invention is to provide, for such air conditioning installations, an air extraction and overpressure device which does not include additional fans which will only operate for relatively short times, or oversized fans, and therefore be less expensive.
  • the device according to the invention is characterized in that it comprises at least one axial fan whose blades have symmetrical leading edge and trailing edge profiles, and allowing its rotation in both directions.
  • Such fans are known in themselves, for example from the document FR-A-973372.
  • this motor is provided with rapid braking means and rapid start of its rotation.
  • This motor is advantageously variable speed.
  • the axial fan 1 driven by the electric motor with variable speed 2 draws the air into the enclosure 3.
  • the air is drawn in as shown by the various arrows a and b in solid lines and passes into two parallel circuits via grids 4, 5 and ducts 6, 7; he is collected in a single duct 8 connected to the shell 9 of the fan. After passing through the fan, it is discharged outside.
  • FIG. 2 shows on a larger scale the assembly constituted by the axial fan 1 fixed on the shaft of its electric drive motor 2, inside the ferrule 9.
  • Seen from the motor side (direction of arrow A): - for extracting air, the fan rotates in the opposite direction to that of clockwise; the blades 10, one of which is shown in section by a plane perpendicular to the plane of the figure, allow the fan to draw the air in the direction of the arrows a and b towards the outside; - for pressurization, the fan turns in the opposite direction, that is to say in the same direction as that of the needles of a watch; the blades 10 allow the fan to discharge the air in the direction of the arrows in broken lines r and s towards the interior of the car.
