Definitions

  • the invention relates to an air outlet from a cylindrical or polygonal outer housing arranged vertically with its central axis.
  • the outer casing is provided with nozzles distributed over the circumference of the casing.
  • An inner housing is arranged inside the outer housing.
  • the casing of the inner housing consists of a perforated plate or sieve.
  • a connection piece is arranged coaxially on the inner housing, which opens into a core space enclosed by the inner housing and projects over an end face of the outer housing.
  • Such air outlets are generally known and enable the generation of a displacement flow with which pollutants can be removed from the area where a room is located without any significant turbulence.
  • the individual air jets are introduced into the room with little turbulence and with little induction. While the perforated plate or sieve forming the jacket of the induction housing ensures an equalization of the supply air distribution over the height and the circumference of the outlet, the nozzles in the jacket of the outer housing increase the jet characteristics.
  • the invention has for its object to propose an air outlet of the type described in the introduction, in which the jet direction of the nozzles can optionally be changed without the need to adjust the nozzles, so that correspondingly complex nozzle designs and adjusting devices can be dispensed with.
  • the flap according to the invention on one end face of the outer housing, depending on the flap opening position, a more or less large volume flow can be introduced directly into the room via the front opening which can also be completely closed by the flap.
  • the nozzles in the Sheath of the outer housing are arranged in a plane adjacent to the flap, the jet direction of the nozzles is influenced in a highly effective manner depending on the degree of opening of the flap, so that a change in the jet direction can be brought about by simply adjusting the flap.
  • the distance at which the inner housing ends from the level of the flap can also influence the jet direction in the closed position of the flap. The larger this distance is selected, the less the supply air jets will fall down, for example, if they are colder than the room air.
  • the supply air jets can also be deflected in a simple manner in such a way that - the further the flap is opened - the more the air jets are deflected from the horizontal to the vertical direction.
  • the air outlet is arranged above a residence area, the area can be heated more quickly in the event of heating.
  • the lounge area can be flushed out intensively at short notice with a vertically introduced air jet.
  • a change of direction of the air jets can then again be carried out as required.
  • two flaps pivotable about an axis are mounted on an end face of the outer housing, the axis dividing the outline of the outer housing into two equal-sized surfaces.
  • This configuration allows the volume flow emerging directly from the air outlet to be divided into two partial flows.
  • the flaps are pivoted independently of one another on the axis, so that the direction of each partial flow and the intensity of the influence of the adjacent nozzles in the casing of the housing can be varied.
  • an embodiment of the invention provides that the connecting piece is connected telescopically to the inner housing and the depth of penetration into the outer housing can be varied.
  • This configuration also allows the jet direction of the nozzles to be influenced, in particular when the flap is closed.
  • the air outlet consists of a hexagonal outer casing 1, which is arranged vertically with its central axis. In the vicinity of one end face, two nozzles 2 are arranged on each of the six sides of the outer housing 1, the central axes of which lie in a horizontal plane.
  • a cylindrical inner housing 3 which is formed from a perforated plate or sieve, is arranged concentrically to the outer housing 1.
  • the outer housing 1 and the inner housing 3 define a free annular space 4, wherein a core space 5 enclosed by the inner housing 3 can be supplied with supply air via a standardized nozzle 6.
  • the connector 6 projects over an end face of the outer housing 1.
  • two flaps 8, which are arranged in mirror image, are pivotably mounted about an axis 7. 4 to 6 and 7 to 9 illustrate, depending on the respective position of the flaps 8, the different flow directions indicated by arrows result.
  • the flaps 8 are in the closed position, so that the volume flow supplied to the air outlets from floor ducts 9 (FIG. 10) or a ceiling duct 10 (FIG. 11) is horizontal into the occupied area (FIG. 10 ) or via this (Fig. 11) is initiated.
  • the volume flow loaded with pollutants is finally discharged via exhaust air ducts 11 and 12 in the ceiling or floor area of the room.
