Definitions

  • the invention relates to an air outlet having at least one outlet plate having at least one air outlet opening and having at least one air deflection device arranged upstream of the air outlet opening.
  • An air outlet of the type mentioned is known. Its air deflector serves to influence the outlet direction of an air flow from the air outlet. Such air outlets serve to ventilate a room, in particular a room with a residence zone for persons.
  • the supplied air may be conditioned, that is, it may be cooled or heated and / or treated for its moisture content.
  • the mentioned air deflector of the known air outlet causes a deflection of the air flow such that - in the case of a ceiling outlet - a ceiling air flow is created, which flows out of an outlet plate of the air outlet not transversely, but longitudinally to this, so that it touches the ceiling of the room to be ventilated applies and dissolves from this only when the pulse energy of the air jets is correspondingly low. Since the size of an air outlet - for example, depending on a ceiling grid of the ceiling of the room - is limited, so is the size of the outlet plate and consequently also limits the size of the other structural devices, which leads to a corresponding limitation of the volume flow of the air, in addition, the sound power level of the outflowing air is taken into account. Such air outlets are therefore to be optimized in terms of the largest possible volume flow with low noise (good acoustics).
  • the latter is an object of the invention, that is, it should be provided an air outlet, which allows a small size as large as possible volume flow of the exiting air at low sound power level.
  • this air outlet is designed as a swirl air outlet, preferably as a ceiling swirl air outlet.
  • an air outlet having at least one outlet plate having at least one air outlet opening and having at least one air guide arranged upstream of the air outlet opening, which has at least one air guide web extending obliquely to the plane of the air outlet opening, the free end region of which - viewed in a direction perpendicular to the plane of the air outlet opening - at least partially in overlapping position to the outlet plate or is displaceable from a non-overlapping position to an overlapping position or to change the degree of overlap from a first Oberlappungsposition to a second Oberlappungsposition, depending on the degree of overlap at least one exiting from the air outlet, along or about along the outlet plate flowing , sets first air flow and / or at least one exiting from the air outlet, transversely or approximately transversely to the outlet plate flowing, second air flow is provided.
  • the degree of overlap of the inclined Lucasleitstegs influence, so that the degree of overlap of the free end portion of the Lucasleitstegs to the outlet - in particular adjacent to the air outlet - is selectable.
  • the degree of overlap is therefore adjustable. In this way, at least one first and / or at least one second air flow can be realized, such that, given a high total volume flow, good acoustic, ie quiet, values are achieved.
  • the first air flow which flows along the outlet plate, thus leading to a ceiling jet in the case of a Deckenluftauslasses, deflects the second air flow by induction, that it is also from its initially transverse or approximately transversely to the air outlet plate flowing direction the direction is deflected along or about along the Beerauslassplatte.
  • the drafts mentioned can be avoided thereby; Nevertheless, a high volume flow per unit area is ensured.
  • the invention thus deliberately goes the way, in principle, to allow a second air flow, which flows transversely or approximately transversely to the air outlet plate, but in this flow direction in space does not come into effect, since it is deflected from said direction by the first air flow by induction effect.
  • the known air outlets make no use of this effect, that is, they are designed so that only along the outlet plate outflowing air streams are provided, so there is no induction induced air deflection. Due to the adjustability of the degree of overlap different positions are adjustable, can be realized in the different flow forms of the exiting air.
  • the air outlet according to the invention for the sake of simplicity in the course of this application, it is usually the case only a first and a second air flow mentioned.
  • an air outlet also has a plurality of first and a plurality of second air flows, that is to say a plurality of air outlet openings with associated air-deflecting devices are formed on an air outlet.
  • the latter is the case in particular in the case of a swirl air outlet according to the invention, which has a multiplicity of essentially radially extending slot-like air outlet openings which are arranged around an imaginary center.
  • Each of the air outlet openings is associated with an air deflecting device.
  • the second air flow is at least partially deflected by the induction effect of the first air flow in a direction extending along or approximately along the outlet plate.
  • the first air flow is generated by a correspondingly high degree of overlap.
  • the free end portion of the Lucasleitstegs - viewed in a right angle to the plane of the air outlet - at least partially in a correspondingly large overlap position to Auslassplatte or can be brought from a Fishbergerlappungsposition in an overlapping position (or vice versa) or is to change the degree of overlap from a first overlap position into one second overlapping position displaceable. If the overlap exceeds a certain value, so that a correspondingly high degree of overlap exists, this results in that the first air flow flows out in the direction along or approximately along the outlet plate from the air outlet.
  • the second air flow is preferably realized in that a correspondingly lower degree of overlap exists, so that the second air flow initially does not flow along or approximately along the outlet plate, but transversely or approximately transversely thereto, but then - as stated above - due to the induction effect of the first air flow is deflected in the direction or approximately in the direction thereof. Accordingly, the procedure is such that, due to a correspondingly low degree of overlap, the second air flow is generated.
  • at least a first and at least a second air flow are generated by means of a single air guide, wherein both air streams emerge from a single air outlet opening.
  • the arrangement is preferably made such that the air guide web has different lengths over its longitudinal extent having the regions for forming the first and the second air flow and / or that the air outlet opening for Forming the first and second air flow over its longitudinal extent has different widths.

  • the air outlet opening is preferably designed as a slot opening, preferably with a constant width. If the constant width at the air outlet opening, it is necessary that the Lucasleitsteg over its regions having longitudinal extent to form the first and the second air flow having different lengths.
  • the formation of the first and second air flows requires that the air outlet opening have different widths over its longitudinal extent.
  • the Luftleitstegtiefe is different in size and the width of the air outlet opening is not constant.
  • the air outlet is designed as a slot air outlet or swirl air outlet. Furthermore, it is preferably conceivable that the air outlet is designed as a wall outlet, floor outlet or ceiling outlet.

  • a corresponding Gutleitsteg tone is made such that its length, ie the Heilleitstegtiefe is reduced in the area, which - viewed in a right angle to the plane of the air outlet - in overlap to a non-matching Air outlet would be, if you would not realize this reduced length.
  • the Luftleitsteg has at least one further area which has an increased length, but the adjacent length is reduced in size, in order to avoid the mentioned coverage.
  • the air outlet openings can be formed very close to each other, that is, per unit area, a large total volume flow can be realized, while still avoiding leakage of air across or approximately transversely to the outlet plate, as in a reduced length of a Air web escaping second air flow through an adjacent first air flow is deflected and also receives a direction along or approximately along the outlet plate.
  • the reduced length of a Lucasleitstegs is selected such that there is a degree of overlap, which leads to the formation of a second air flow, as already mentioned above.
