Definitions

  • the present invention relates to an air extraction device for conditioning the atmosphere of a rail 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 are called on to operate only for relatively short times, nor oversized fans, and is therefore 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.
  • 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.
  • we stop the fan if necessary by braking it to increase its deceleration, and we start it in reverse. If necessary, increase its speed of rotation so that in absolute value it reaches a value higher than that used for the extraction of air.
  • the fan then delivers outside air inside the car, following the arrows in broken lines r and s in the duct 8, the ducts 6 and 7 and the interior 3 of the car.
  • 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.
