Definitions

  • a ventilation device provided with a grille, pivotable along its lower edge and preferably arranged in a box, having a perforated front face and upper flange for horizontal and vertical air flow, respectively, for distributing air towards a window wall of a room from a duct outlet in an inner wall of said room. Exposure of the upper flange is adjusted by a setscrew passing through the grille front and threaded into a partially sound insulating wall having less height than the grille and being arranged between same and the duct. Air flow, regulated by throttling means in the duct connection, is adjusted by screwdriver through a front grille perforation.
  • the upwardly directed air stream is deflected along the ceiling of the room, and exerts a certain intermingling effect on the principally horizontally flowing air, thereby attaining quick admixture and distribution of the individual currents (streams) of air, and with the air in the room.
  • cold air never reaches the opposite wall, but is mixed up with the warm room air at some distance in front of the outside (outer) wall of the room.
  • fresh air having a relatively low temperature, e.g. only 14C, can be used, when the temperature of the air in the rest of the room is 24C. Discomfort from convection currents and other air draughts in occupancy zones of the room therefore does not arise.
  • the grille element can be provided with a perforated flange at its upper edge, the flange extending into the duct outlet, and the grille element being adjustable in such a way that the flange can be more or less exposed.
  • the grille When it is open, the grille thereby allows air to flow not only principally at right angles to the plane of the grille, but alsoupwards through the perforated flange.
  • FIG. 3 displays in an even larger scale a cross section along a plane denoted by the lines 33 in FIG. 2.
  • the outer wall is designated by the numeral 1, in a room having a window 2, and an oppositeinner wall 3.
  • a ventilation duct 4 carrying fresh air intended to flow into the room.
  • a box 5 the outward side of which, turned towards the room, is provided with a grille-like element 6.
  • Box 5 is on its outward side provided with a flange 7 extending like a frame around the box and intended to cover the edges of the opening in the wall in which the box is inserted.
  • the grille element Along its lower edge the grille element has a flange 8 folded inwards, which goes under a retainer 9, shaped like a half-stirrup, thus forming a joint which makes it possible to swing the grille element somewhat outwards and inwards about its lower edge.
  • the grille element 6 is upwardly provided with an inwardly directed flange 10, having a number of holes 11, for the passage of air.
  • the grille element is also provided with air passage holes 12.
  • a setscrew 14 extends through the grille into an intermediate wall 15, situated inside the box. Around screw 14 there is placed a spring 16, compressed between the grille element 6 and the intermediate wall 15. By tightening or loosening screw 14 the grille element can be moved outwards or inwards, so that flange 10 with its holes 11 is exposed to a greater or lesser extent outside the-outward edge of the box.
  • the intermediate wall 15 extends downwards a portion from the upper side of the box, but terminates above the bottom of the box so that a through flow area or slot 17 is formed here, extending from one side of the box to the other.
  • the box is provided on one side with an air intake stub 18, flow-through being regulated by a throttle butterfly 19, mounted on a rotatable shaft 20 provided with an arm 21.
  • arm 21 is joined by link 22 to a crank 23 mounted on turning pin 24.
  • This pin is provided with a screwdriver slot 25, opposite an opening in the grille element 6. This arrangement allows setting the throttle 19 to a more or less open position by turning pin 24 in one or the other direction with a screwdriver.
  • the modus operandi of the device which has been described is mainly as follows. If the grille element 6 has been adjusted by the setscrew 14 to the position shown in FIG. 3 by full lines, air flows from the box principally at right angles to the plane of the grille, i.e. horizontally out into the room from wall 3 towards the outer wall 1. Hereby there is the risk that the cold air 3 follows down along the outside wall and reinforces the downdraught from window 2, giving rise to a floor draught. If, on the other hand, the grille is swung out to the position shown by dotted lines in FIG. 3, by tuming the setscrew l4 and with the help of the bias from spring 16, the holes 11 facing upwards in flange are exposed.
  • the air flowing into the box flows down into area 17 under the intermediate wall and is here distributed along the whole width of the box.
  • the wall 15 also has a sound insulating effect, allowing the device to accept relatively large amounts of air without causing a disturbing noise.
  • a pressure measuring outlet can be arranged in the box, this outlet being connected to a micro pressure gauge on which the pressure drop can be read according to the adjustment of throttle 19.
  • An air distributing device for distributing air flowing into a room having an inner wall from a duct outlet in said inner wall and discharging air into the room, said air from the duct being discharged into the room through said device at least a portion of which is disposed in said duct outlet, said device comprising a boxlike housing having air inlet means and air outlet means for feeding air into the room, said outlet means having primary and secondary air openings in a grille element which is movably fitted in a front wall of said housing and which determines two flow directions into the room, one said direction being upward and the other said direction being substantially horizontally in the room, an upper edge of said grille element comprising a perforated flange extending into the housing toward the rear portion of the device and containing said secondary openings, and means mounting the grille element for adjustive movement into different positions in the housing front wall in such a manner that the flange openings are exposed to a greater of lesser extent, the air thereby passing through the grille element not only mainly at right angles to the plane of said element
