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.

- 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.

Subsequently, the proportion of the respective profile length is calculated, in which an air flow along or about along the outlet plate is no longer possible, but in which there is an air flow, which basically flows transversely or approximately transversely to the outlet plate. In a subsequent step, the profile lengths are optimized until a maximum allowable limit is reached at which the second air stream is forced by the first air stream to also flow longitudinally or approximately along the outlet plate. As a result, an inventively optimized air outlet 1 is then present.

Abstract
Description
Die Erfindung betrifft einen Luftauslass mit mindestens einer mindestens eine Luftauslassöffnung aufweisenden Auslassplatte und mit mindestens einer stromaufwärts der Luftauslassöffnung angeordneten Luftlenkeinrichtung.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.
Ein Luftauslass der eingangs genannten Art ist bekannt. Seine Luftlenkeinrichtung dient der Beeinflussung der Austrittsrichtung eines Luftstroms aus dem Luftauslass. Derartige Luftauslässe dienen dazu, einen Raum, insbesondere einen Raum mit einer Aufenthaltszone für Personen, zu belüften. Die zugeführte Luft kann konditioniert sein, das heißt, sie kann gekühlt oder erwärmt und/oder hinsichtlich ihrer Feuchte behandelt sein. Die vorstehenden Ausführungen gelten sowohl für den Stand der Technik als auch für den Gegenstand der Erfindung. Um Zugerscheinungen zu vermeiden, ist es geboten, dass der aus dem Luftauslass austretende Luftstrom nicht direkt in den Aufenthaltsbereich gelangt, also beispielsweise bei einem Deckenluftauslass nicht senkrecht nach unten ausgeblasen wird, da dies als unangenehm empfunden wird. Die erwähnte Luftlenkeinrichtung des bekannten Luftauslasses bewirkt eine Umlenkung des Luftstroms derart, dass - im Falle eines Deckenauslasses - ein Deckenluftstrom geschaffen wird, der aus einer Auslassplatte des Luftauslasses nicht quer, sondern längs zu dieser ausströmt, sodass er sich an die Decke des zu belüftenden Raumes anlegt und sich von dieser erst ablöst, wenn die Impulsenergie der Luftstrahlen entsprechend niedrig ist. Da die Größe eines Luftauslasses - beispielsweise in Abhängigkeit von einem Deckenraster der Decke des Raumes - begrenzt ist, ist auch die Größe des Auslassplatte und demzufolge auch die Größe der sonstigen konstruktiven Einrichtungen begrenzt, was zu einer entsprechenden Begrenzung des Volumenstromes der Luft führt, wobei zusätzlich der Schallleistungspegel der ausströmenden Luft zu berücksichtigen ist. Derartige Luftauslässe sind daher im Hinblick auf einen möglichst großen Volumenstrom bei niedrigem Geräusch (guter Akustik) zu optimieren.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 above statements apply both to the prior art and to the subject matter of the invention. In order to avoid drafts, it is necessary that the air flow exiting the air outlet does not get directly into the occupied area, that is, for example, not blown down vertically at a ceiling air outlet, as this is perceived as unpleasant. 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).
Letzteres ist Aufgabe der Erfindung, das heißt, es soll ein Luftauslass bereitgestellt werden, der bei kleiner Baugröße einen möglichst großen Volumenstrom der austretenden Luft bei niedrigem Schallleistungspegel ermöglicht. Insbesondere ist dieser Luftauslass als Drallluftauslass, bevorzugt als Decken-Drallluftauslass, ausgebildet.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. In particular, this air outlet is designed as a swirl air outlet, preferably as a ceiling swirl air outlet.
Diese Aufgabe wird gelöst durch einen Luftauslass mit mindestens einer mindestens eine Luftauslassöffnung aufweisenden Auslassplatte und mit mindestens einer stromaufwärts zur Luftauslassöffnung angeordneten Luftlenkeinrichtung, die mindestens einen schräg zur Ebene der Luftauslassöffnung verlaufenden Luftleitsteg aufweist, dessen freier Endbereich - in rechtwinkliger Richtung zur Ebene der Luftauslassöffnung betrachtet - zumindest bereichsweise in Überlappungsposition zur Auslassplatte liegt oder aus einer Nichtüberlappungsposition in eine Überlappungsposition oder zur Änderung des Überlappungsgrads aus einer ersten Oberlappungsposition in eine zweite Oberlappungsposition verlagerbar ist, wobei sich in Abhängigkeit vom Überlappungsgrad mindestens ein aus dem Luftauslass austretender, längs oder etwa längs der Auslassplatte strömender, erster Luftstrom einstellt und/oder mindestens ein aus dem Luftauslass austretender, quer oder etwa quer zur Auslassplatte strömender, zweiter Luftstrom vorgesehen ist.This object is achieved by 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.
Aufgrund der erfindungsgemäßen Ausgestaltung lässt sich der Überlappungsgrad des schräg stehenden Luftleitstegs beeinflussen, sodass also der Grad der Überlappung des freien Endbereichs des Luftleitstegs zur Auslassplatte - insbesondere angrenzend an die Luftauslassöffnung - wählbar ist. Der Überlappungsgrad ist daher verstellbar. Damit lässt sich mindestens ein erster und/oder mindestens ein zweiter Luftstrom realisieren, derart, dass bei hohem Gesamtvolumenstrom gute akustische, also leise, Werte erzielt werden. Dabei ist bevorzugt sichergestellt, dass der erste Luftstrom, der längs der Auslassplatte strömt, also im Falle eines Deckenluftauslasses zu einem Deckenstrahl führt, durch Induktionswirkung den zweiten Luftstrom derart umlenkt, dass er aus seiner anfänglich quer oder etwa quer zur Luftauslassplatte strömenden Richtung ebenfalls ist in die Richtung längs oder etwa längs der Luftauslassplatte umgelenkt wird. Die erwähnten Zugerscheinungen lassen sich dadurch vermeiden; gleichwohl ist ein hoher Volumenstrom pro Flächeneinheit gesichert. Die Erfindung geht also bewusst den Weg, grundsätzlich einen zweiten Luftstrom zuzulassen, der quer oder etwa quer zur Luftauslassplatte strömt, in dieser Strömungsrichtung im Raum jedoch nicht zur Geltung gelangt, da er aus der genannten Richtung durch den ersten Luftstrom durch Induktionswirkung umgelenkt wird. Die bekannten Luftauslässe machen von dieser Wirkung keinen Gebrauch, das heißt, sie sind so konstruiert, dass nur längs zur Auslassplatte ausströmende Luftströme vorgesehen sind, also keine durch Induktion bewirkte Luftumlenkung vorliegt. Aufgrund der Verstellbarkeit des Überlappungsgrads sind verschiedene Stellungen einstellbar, in den verschiedene Strömungsformen der austretenden Luft realisiert werden können. Bei dem erfindungsgemäßen Luftauslass wird der Einfachheit halber im Zuge dieser Anmeldung zumeist nur ein erster und ein zweiter Luftstrom erwähnt. Selbstverständlich ist es denkbar, dass ein Luftauslass auch mehrere erste und mehrere zweite Luftströme aufweist, dass also eine Vielzahl von Luftauslassöffnungen mit zugehörigen Luftlenkeinrichtungen an einem Luftauslass ausgebildet sind. Letzteres ist insbesondere bei einem erfindungsgemäßen Drall-Luftauslass der Fall, der eine Vielzahl von im Wesentlichen radial verlaufenden, langlochartigen Luftauslassöffnungen aufweist, die um einen gedachten Mittelpunkt herum angeordnet sind. Jeder der Luftauslassöffnungen ist eine Luftlenkeinrichtung zugeordnet.Due to the inventive design, the degree of overlap of the inclined Luftleitstegs influence, so that the degree of overlap of the free end portion of the Luftleitstegs 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. In this case, it is preferably ensured that 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 Luftauslassplatte. 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. In the case of 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. Of course, it is conceivable that 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.
Wie bereits erwähnt, ist vorzugsweise vorgesehen, dass der zweite Luftstrom durch Induktionswirkung des ersten Luftstroms zumindest teilweise in längs oder etwa längs der Auslassplatte verlaufender Richtung umgelenkt wird.As already mentioned, it is preferably provided that 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.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der erste Luftstrom durch einen entsprechend hohen Überlappungsgrad erzeugt ist. Der freie Endbereich des Luftleitstegs liegt - in rechtwinkliger Richtung zur Ebene der Luftauslassöffnung betrachtet - zumindest bereichsweise in entsprechend großer Überlappungsposition zur Auslassplatte oder kann aus einer Nichtüberlappungsposition in eine Überlappungsposition (beziehungsweise umgekehrt) gebracht werden oder ist zur Änderung des Überlappungsgrads aus einer ersten Überlappungsposition in eine zweite Überlappungsposition verlagerbar. Überschreitet die Überlappung einen bestimmten Wert, sodass ein entsprechend hoher Überlappungsgrad vorliegt, so führt dies dazu, dass der erste Luftstrom in Richtung längs oder etwa längs der Auslassplatte aus dem Luftauslass ausströmt. Wird also dieser entsprechend hohe Überlappungsgrad erzeugt, so bildet sich der erste Luftstrom aus. Der zweite Luftstrom wird bevorzugt dadurch realisiert, dass ein entsprechend geringerer Überlappungsgrad vorliegt, sodass der zweite Luftstrom zunächst nicht längs oder etwa längs der Auslassplatte strömt, sondern quer oder etwa quer zu dieser, dann jedoch - wie vorstehend ausgeführt - aufgrund der Induktionswirkung des ersten Luftstroms in dessen Richtung oder etwa in dessen Richtung umgelenkt wird. Demzufolge wird derart vorgegangen, dass aufgrund eines entsprechend niedrigen Überlappungsgrads der zweite Luftstrom erzeugt wird.According to a development of the invention it is provided that the first air flow is generated by a correspondingly high degree of overlap. The free end portion of the Luftleitstegs - 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 Nichtüberlappungsposition 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. So if this correspondingly high degree of overlap is generated, it forms the first air flow out. 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.
Nach einer Weiterbildung der Erfindung ist insbesondere vorgesehen, dass durch die Ausbildung des Luftleitstegs und/oder der Luftauslassöffnung der Überlappungsgrad bereichsweise derart gewählt wird, dass sich in mindestens einem ersten Bereich des Luftleitstegs der erste Luftstrom und in mindestens einem zweiten Bereich des Luftleitstegs der zweite Luftstrom einstellt, wobei die beiden Luftströme vorzugsweise aus derselben Luftauslassöffnung austreten. Mithin werden mittels eines einzigen Luftleitsteges mindestens ein erster und mindestens ein zweiter Luftstrom erzeugt, wobei beide Luftströme aus einer einzigen Luftauslassöffnung austreten. Realisiert wird dies dadurch, dass der Luftleitsteg nicht überall den gleichen Überlappungsgrad aufweist, sondern in verschiedenen Bereichen unterschiedliche Überlappungsgrade, sodass die beiden unterschiedlichen Luftströme (erster Luftstrom und zweiter Luftstrom) erzeugt werden.According to a development of the invention, provision is made in particular for the degree of overlap to be selected in regions in such a way that the first air stream is present in at least a first region of the air guide web and the second air stream in at least a second region of the air guide web adjusts, wherein the two air streams preferably exit from the same air outlet opening. Thus, 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. This is realized by the fact that the Luftleitsteg not everywhere has the same degree of overlap, but in different areas different degrees of overlap, so that the two different air flows (first air flow and second air flow) are generated.
Die Anordnung ist vorzugsweise derart getroffen, dass der Luftleitsteg über seine die Bereiche aufweisende Längserstreckung zur Ausbildung des ersten und des zweiten Luftstroms unterschiedlich große Längen aufweist und/oder dass die Luftauslassöffnung zur Ausbildung des ersten und des zweiten Luftstroms über ihre Längserstreckung unterschiedlich große Breiten aufweist. Unter "Länge des Luftleitstegs" ist praktisch die Luftleitstegtiefe, also die Strecke zu verstehen, entlang der die Stromfäden des Luftstroms richtungsmäßig verlaufen. Dazu gehört eine entsprechende Breite der zugehörigen Luftauslassöffnung. Bevorzugt ist die Luftauslassöffnung als Langlochöffnung, vorzugsweise mit konstanter Breite, ausgebildet. Liegt die konstante Breite bei der Luftauslassöffnung vor, so ist es erforderlich, dass der Luftleitsteg über seine die Bereiche aufweisende Längserstreckung zur Ausbildung des ersten und des zweiten Luftstroms unterschiedlich große Längen aufweist. Weist der Luftleitsteg über seine Längserstreckung überall die gleiche Länge, also überall die gleiche Luftleitstegtiefe auf, so ist es zur Ausbildung des ersten und des zweiten Luftstroms erforderlich, dass die Luftauslassöffnung über ihre Längserstreckung unterschiedlich große Breiten aufweist. Selbstverständlich ist aus beiden vorstehend genannten Möglichkeiten auch eine Kombination denkbar, das heißt, die Luftleitstegtiefe ist unterschiedlich groß und die Breite der Luftauslassöffnung ist nicht konstant.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 term "length of the air guide bar" is to be understood in practice as meaning the air guide depth, that is to say the distance along which the current threads of the air flow extend in direction. This includes a corresponding width of the associated air outlet. 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 Luftleitsteg over its regions having longitudinal extent to form the first and the second air flow having different lengths. If the air guide web has the same length over its longitudinal extent, ie the same air guide depth, the formation of the first and second air flows requires that the air outlet opening have different widths over its longitudinal extent. Of course, a combination is conceivable from the above two possibilities, that is, the Luftleitstegtiefe is different in size and the width of the air outlet opening is not constant.
Insbesondere kann vorgesehen sein, dass der Luftauslass als Schlitzluftauslass oder Drallluftauslass ausgebildet ist. Ferner ist es vorzugsweise denkbar, dass der Luftauslass als Wandauslass, Fußbodenauslass oder Deckenauslass ausgebildet ist.In particular, it can be provided that 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.
Nach einer Weiterbildung der Erfindung kann vorgesehen sein, dass die Luftlenkeinrichtung an einer Drallscheibe ausgebildet ist. Eine Drallscheibe liegt im Falle eines Drallluftauslasses vor. Dieser Drall-luftauslass besitzt eine Auslassplatte, der - stromaufwärts liegend - die Drallscheibe zugeordnet ist, wobei Auslassplatte und Drallscheibe parallel zueinander verlaufen, vorzugsweise flach aufeinanderliegend angeordnet sind. Die Drallscheibe lässt sich relativ zur Auslassplatte verstellen, insbesondere um einen gedachten Mittelpunkt herum verdrehen.According to a development of the invention it can be provided that the air-directing device is formed on a swirl disk. A swirl disk is provided in the case of a swirl air outlet. This swirl air outlet has an outlet plate which, upstream, is associated with the swirl disk, with outlet plate and swirl disk parallel to each other, preferably arranged flat on top of each other. The swirl disk can be adjusted relative to the outlet plate, in particular rotate around an imaginary center.
Insbesondere weist der Luftauslass mehrere Luftauslassöffnungen mit zugeordneten Luftlenkeinrichtungen auf.In particular, the air outlet has a plurality of air outlet openings with associated air deflection devices.
Die Luftaustrittsöffnungen sind vorzugsweise derart benachbart zueinander liegend ausgebildet, dass mindestens ein Luftleitsteg zur Vermeidung einer zumindest abschnittsweise erfolgenden Überdeckung mit einer nicht mit diesem Luftleitsteg zugeordneten Luftauslassöffnung zumindest in einem Abschnitt eine verminderte Länge aufweist. Um Überdeckungen der einzelnen Baugruppen des erfindungsgemäßen Luftauslasses zu vermeiden, wird eine entsprechende Luftleitstegausbildung vorgenommen, derart, dass seine Länge, also die Luftleitstegtiefe, in dem Bereich vermindert ist, der - in rechtwinkliger Richtung zur Ebene der Luftauslassöffnung betrachtet - in Überlappung zu einer nicht dazugehörenden Luftauslassöffnung liegen würde, wenn man diese verminderte Länge nicht realisieren würde. Dies bedeutet, dass der Luftleitsteg zumindest einen weiteren Bereich aufweist, der eine vergrößerte Länge aufweist, die benachbart dazu liegende Länge jedoch verkleinert ist, um die erwähnte Überdeckung zu vermeiden. Aufgrund dieser besonders bevorzugten Anordnung lassen sich die Luftauslassöffnungen sehr eng benachbart zueinander ausbilden, das heißt, pro Flächeneinheit lässt sich ein großer Gesamtvolumenstrom realisieren, wobei gleichwohl ein Austreten von Luft quer oder etwa quer zur Auslassplatte vermieden ist, da ein im Bereich einer verminderten Länge eines Luftstegs austretender zweiter Luftstrom durch einen benachbarten ersten Luftstrom umgelenkt wird und ebenfalls eine Richtung längs oder etwa längs der Auslassplatte erhält.The air outlet openings are preferably formed adjacent to each other so that at least one Luftleitsteg to avoid an at least partially taking place covering with a not associated with this Luftleitsteg air outlet at least in a section has a reduced length. In order to avoid overlaps of the individual components of the air outlet according to the invention, a corresponding Luftleitstegausbildung is made such that its length, ie the Luftleitstegtiefe 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. This means that 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. Because of this particularly preferred arrangement, 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.
Nach einer Weiterbildung der Erfindung ist die verminderte Länge eines Luftleitstegs derart gewählt, dass sich ein Überlappungsgrad ergibt, der zur Ausbildung eines zweiten Luftstroms führt, wie dies bereits vorstehend erwähnt wurde.According to a development of the invention, the reduced length of a Luftleitstegs is selected such that there is a degree of overlap, which leads to the formation of a second air flow, as already mentioned above.
Sofern ein Drallauslass realisiert wird, ist insbesondere eine Radialanordnung von Luftauslassöffnungen zueinander vorgesehen.If a twist outlet is realized, in particular a radial arrangement of air outlet openings is provided to one another.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Luftauslassöffnung und der zugeordnete Luftleitsteg hinsichtlich des Überlappungsgrads derart ausgebildet sind, dass sich die aus der Luftauslassöffnung austretende Luft zu 55 % bis 95 %, vorzugsweise zu etwa 75 %, aus dem ersten Luftstrom und zu 5 % bis 45 %, vorzugsweise etwa zu 25 %, aus dem zweiten Luftstrom zusammensetzt.According to a development of the invention, it is provided that the air outlet opening and the associated Luftleitsteg are formed with respect to the degree of overlap that the emerging from the air outlet opening air to 55% to 95%, preferably about 75%, from the first air flow and the fifth % to 45%, preferably about 25%, composed of the second air stream.

Für den Fall, dass der erfindungsgemäße Luftauslass als Deckenluftauslass ausgebildet ist und insbesondere einen Drallluftauslass bildet, bringt dieser in den zu belüftenden Raum Luft als Deckenstrahlen ein. Dabei ist es möglich, einen größeren Volumenstrom bei gegenüber den bisherigen Luftauslässen gleichbleibender Akustik (Schalldruckpegel) oder einen leiseren Drallluftauslass zu schaffen bei gegenüber den bisherigen Luftauslässen gleichem Volumenstrom.In the event that the inventive air outlet is designed as a ceiling air outlet and in particular forms a swirl air outlet, this brings in the air to be ventilated room as ceiling beams. It is possible to provide a larger volume flow with respect to the previous air outlets constant acoustics (sound pressure level) or a quieter swirl air outlet at the same volume flow compared to the previous air outlets.
Es ist erreicht, dass ein Anteil der ausströmenden Luft vorzugsweise senkrecht nach unten austreten will, wobei dieser Anteil jedoch so bemessen ist, dass der verbleibende, austretende Deckenstrahl den senkrecht nach unten ausströmenden Anteil des Volumenstroms aufgrund von Induktionswirkung mitreißt und somit auch zu einem Deckenstrahl zwingt. Vorzugsweise können auch Überlappungsgrade realisiert sein, bei denen die gesamte Luft oder ein Anteil davon längs oder etwa längs der Auslassplatte (insbesondere horizontal oder etwa horizontal) oder quer zur Auslassplatte (insbesondere vertikal oder etwa vertikal) strömt, wobei also kein mitreißendes Umlenken erfolgt.It is achieved that a portion of the outflowing air preferably wants to exit vertically downwards, but this proportion is so dimensioned that the remaining, emerging ceiling jet entrains the vertically downwardly flowing portion of the volume flow due to induction effect and thus also forces a ceiling jet , Preferably, overlapping degrees can also be realized in which all or part of the air flows along or approximately along the outlet plate (in particular horizontally or approximately horizontally) or transversely to the outlet plate (in particular vertically or approximately vertically), that is to say without any enticing deflection.
Wie vorstehend erläutert, wird durch konstruktive Maßnahme entlang der Länge D einer Luftauslassöffnung 12 beziehungsweise eines Luftleitstegs 21 die Überlappung, das heißt der Überlappungsbereich A variiert. Vorzugsweise beträgt der Anteil mit einem Überlappungsgrad, der zu der Ausbildung eines ersten Luftstroms 25 führt, etwa 75 % und der Anteil mit einem Überlappungsgrad, der zur Ausbildung eines zweiten Luftstroms 26 führt, etwa 25 %; jeweils bezogen auf eine Luftleiteinrichtung. Durch die erfindungsgemäßen Maßnahmen können die einzelnen Luftauslassöffnungen 12 und zugehörigen Luftlenkeinrichtungen 16 - wie insbesondere die
Bei der Auslegung des erfindungsgemäßen Luftauslasses wird derart vorgegangen, dass in Abhängigkeit von der Profilbreite der Luftleitstege 21, also von deren jeweiligem, den Überlappungsgrad bestimmenden Maß der zur Verfügung stehende Platz auf der Luftlenkplatte, insbesondere Drallscheibe 15, berechnet wird, der für die Ausbildung eines Luftstroms längs oder etwa längs der Auslassplatte benötigt wird. Anschließend wird der Anteil der jeweiligen Profillänge berechnet, bei dem ein Luftstrom längs oder etwa längs der Auslassplatte nicht mehr möglich ist, sondern bei dem es zu einem Luftstrom kommt, der grundsätzlich quer oder etwa quer zur Auslassplatte strömt. In einem Folgeschritt werden nun die Profillängen solange optimiert, bis ein maximal zulässiger Grenzwert erreicht wird, bei dem der zweite Luftstrom vom ersten Luftstrom gezwungen wird, ebenfalls längs oder etwa längs der Auslassplatte zu strömen. Als Ergebnis liegt dann ein erfindungsgemäß optimierter Luftauslass 1 vor.In the design of the air outlet according to the invention, the procedure is such that depending on the profile width of the
Aus dem Vorstehenden wird deutlich, dass es für die Ausbildung eines ersten oder zweiten Luftstroms entscheidend ist, wie groß der Überlappungsgrad im jeweils betrachteten Bereich eines Luftleitstegs 21 mit zugehörigem Bereich der Luftauslassöffnung 12 ist. Damit wird deutlich, dass es auf die Auskragweite des Luftleitstegs und die dazugehörige Breite der Luftauslassöffnung ankommt. Demzufolge kann sowohl die Auskraglänge des Luftleitstegs als auch die Breite der Luftauslassöffnung variiert werden. Es sind also Lösungen möglich, bei denen eine entsprechende Länge des Luftleitstegs vorliegt oder eine entsprechende Breite der Luftauslassöffnung oder eine Kombination beider Parameter. Zusätzlich oder alternativ ist es denkbar, dass der Luftleitsteg nicht eben, sondern über seine Längserstreckung verdrillt ausgebildet ist, wodurch er über seine Längserstreckung gegenüber einem Öffnungsrand der Luftauslassöffnung, insbesondere geraden Öffnungsrand der Luftauslassöffnung, unterschiedliche Überlappungsgrade aufweist.From the above it is clear that it is crucial for the formation of a first or second air flow, how large the degree of overlap in each considered area of a
