Definitions

  • the invention relates to a ventilation apparatus with the arrangement of a ventilator adapted to be driven by motor, for the rooms of a building, particularly of a stable, said apparatus comprising an axial-flow fan drawing in the used air from the room of the building via a vertically downwardly extending used-air draw-in duct, and delivering it to an outlet duct extending essentially horizontally outwardly which is arranged below a likewise outwardly extending fresh-air duct through which the fresh-air is drawn-in into the room by a pressure below atmospheric created by the axial-flow fan in the room of the building.
  • venting arrangements are in addition provided with speed adjustable fans, the speed of the fans being especially adjusted in dependence upon the temperature of the interior of the room.
  • another disadvantage may result which has an unfavourable influence on the venting stream.
  • the inflow speed of the air will decrease, so that the air stream drawn-in will very soon approach the bottom area in a short curved path.
  • the through-flow also did not cover the entire width of the outlet nozzle but preferably only the center thereof or, in case of a small fresh air proportion due to the rotary effect of the fan, also took place only in one corner of the nozzle member provided for the outflowing air.
  • the air exit and air inlet openings were lying closely side by side outside the building, it was not always possible to avoid contamination of the entering air by floating particles from the outgoing air.
  • the invention is concerned with the problem of improving the flow and distribution of the air of a ventilation apparatus within the room of the building and to take care that when drawing-in fresh air it is practically ensured that the amount of fresh air drawn-in is not contaminated by the outgoing used air.
  • the axial-blow fan is arranged in that part of the horizontal used-air duct which is located about in the range of the wall of the building.
  • the fan is located about midway between the draw-in opening of the used air draw-in duct and the air discharge opening of the nozzle member, so that draught phenomena are largely avoided and the air drawn-in by the fan without any draught phenomena occurring, is uniformly distributed at the air discharge opening of the nozzle member.
  • the used air draw-in duct may also be designed to have extremely small dimensions and may in particular be designed to be very low, so that the assembly thereof also in such buildings which are provided with stationary installations does not cause any difliculties.
  • the connecting duct consists of an opening which is provided in the partition wall between the fresh-air duct and the horizontal used air duct. It is recommendable to arrange the bearing of the throttle flap on that side of the connection duct which is averted from the housing wall. In this manner one may have the connection duct start directly adjacent the wall of the building and achieves in spite of this a d accessibility to the bearing of the throttle flap.
  • the invention is furthermore improved by the feature that the air discharge opening of the nozzle member is closed by means of a flap retained in its position by means of a weight or by means of a spring, with the axis of rotation of the flap disposed on the lower edge thereof. In this way, an essentially uniform overpressure is maintained in the nozzle member.
  • the nozzle member is provided with several air baflies which contribute to improve the uniformity of the amount of air respectively flowing towards the nozzle member over the entire cross sectional area and the entire width thereof.
  • the invention is furthermore improved by the fact that the fresh air draw-in opening is averted from the blowout opening. While the blow-out duct and the blow-out opening are facing upwardly and away from the wall of J the building, the fresh air inlet opening is facing downwardly and towards the wall of the building. In this way, the amount of fresh air drawn-in is not only not subjected to being mixed with the outgoing used air but is protected from outer influences such as wind and heavy rain.
  • FIG. 1 shows a sectional view taken on the subject matter of the invention with the throttle flap open
  • FIG. 2 shows a sectional view similar to FIG. 1, however, with the throttle flap closed
  • FIG. 3 shows a sectional view taken on the outflow opening of the nozzle with the pendulum flap closed
  • FIG. 4 is a perspective, partially broken away view of the subject matter of the application taken from outside, with the throttle flap open and the pendulum flap closed, the wall of the housing being eliminated,
  • FIG. 5 is a perspective view of the air outlet opening of the nozzle with the pendulum flap open
  • FIG. 6 is an exploded representation of the subject matter of the invention, simultaneously illustrating the manner in which the individual parts of the venting equipment are made in detail and assembled in the site.
  • 1 designates the room of the building and 2 designates a wall of the building.
  • the venting equipment generally designated with 3 essentially consists of a center or main box 5 which is pushed into an opening 6 of the wall of the building and which serves to support an axial-blow fan 11 and a double flap 20.
  • a draw-in duct box 4 and a nozzle member 8 are fastened in a manner described in more detail below, while on the outwardly facing side of the center box 5 there is fastened in some suitable manner an outer box 28 essentially serving to form an air inlet opening 14.
  • the individual boxes preferably consist of sheet metal but may also be made of synthetic resin, in particular, glass fiber reinforced synthetic resin.
  • the sheet metal box 5 comprises a short horizontal partition wall 29 facing towards the room 1 of the building, above which the nozzle member 8 is fastened to the center box 5, said nozzle member serving to discharge the fresh air or return air into the room 1 of the building and terminating into an opening 9. Below the partition wall 29, the draw-in duct box 4 is fastened at the center box 5.
  • the center box 5 On its side facing towards the room 1 of the housing, the center box 5 is provided with two flanges 30, 31 extending in parallel with respect to each other.
  • the flange 30 lies close against the wall 2 of the building from inside; the flange 31 serves to fasten the nozzle member 8 and the draw-in duct box 4.
  • the box 4 forms a usedair, draw-in duct 7 the upper end. of which terminates in a horizontal used-air duct 10 formed by the center box 5 in which the axial fan is fitted with the axis of rotation thereof extending essentially horizontally.
  • the axial-blow fan accordingly, is supported in the region of the wall 2 of the building.
  • the outer box 28 is provided with a horizontally extending used-air pressure duct 12 constituting a continuation of the horizontal duct 10 of the center box 5. At the end of the used-air pressure duct 12 there is provided a deflection plate 13 which deflects the used-air leaving via the opening 14, upwardly.
  • FIGS. 1 and 2 are dfsposed vertically with respect to the plane of the drawing and are recognizable in FIGS. 4 and 6.
  • the two fresh air openings in FIGS. 1 and 2 are dfsposed vertically with respect to the plane of the drawing and are recognizable in FIGS. 4 and 6.
  • mountable plate 32 extends on both sides beyond the outer box 28.
  • the used-air pressure duct 10 and the fresh-air duct 15 are interconnected by means of a connecting duct 17 which begins immediately behind the fan 11 and the short partition wall 29 and, in the example of embodiment, consists only of an opening provided in the partition wall 29 between the used-air pressure duct 12 and the freshair duct 15.
  • the bearing 19 for a double flap generally referenced by 20 and consisting of two flap halves 21 and 22.
  • the double flap 20 is shown. in its one end position. In this end position, the connection opening 17 is blocked by the flap half 21.
  • the flap half 22 lies close to the partition wall 18 and is supported on an inclined portion of the partition wall 29. In this end position of the double flap 20, the used-air presure ducts 12, 10 and the fresh-air inlet duct 15 are fully open.
  • FIG. 2 shows the other end position of the double flap 20.
  • the fresh-air inlet duct 15 is blocked by the double flap half 21 while the double flap half 22 closes the used-air pressure duct 10, 12.
  • the entire amount of the used-air which has been sucked-off from the room 1 by the axial-blow fan 11, is returned via the nozzle member 8 and the opening 9 into the room of the building.
  • the opening 9 of the nozzle member 9 is closed by a pendulum flap 24 pivotally supported at its lower edge and provided with a counter weight 23.
  • the pendulum flap takes care that a uniform overpressure is maintained in the nozzle member 8 and the outflowing air presses the pendulum flap out of its vertical position against the effect of the weight 23, the extended upper cover plate 25 of the nozzle member 8 preventing the air from being deflected upwardly by the inclined pendulum flap 24. A lateral deviation of the air flow is prevented by the extended side walls 26 of the nozzle member 8.
  • the nozzle member 8 is furthermore provided with several vertically arranged baflles 27 (FIGS. 4 and 5) which are beginning at the merging point of the freshair duct 15 with the nozzle member 8, i.e., in the inner region of the wall 2 of the building and, with spaced apart horizontal axes, are extending approximately in parallel with the air flow to the outlet opening 9 of the nozzle member 8.
