Abstract

The slats which are disposed at the bottom of the air outlet are rotatably mounted and have vanes which define an angle therebetween of other than 180 DEG . The slats can be adjusted to a desired angular position and fixed by threaded screw connections. The adjustment of the slats permits the direction of the discrete air streams issuing from the outlet to be controlled.

Description

Die Erfindung betrifft einen rechteckigen Luftauslass für Raumklima-Anlagen zum Anschluss an einen Zuluftkanal im Deckenbereich eines Raumes, welcher Luftauslass senkrecht zu seinen seitlichen Begrenzungen verlaufende Leitelemente für beide vertikal zueinander stehenden Richtungen der Deckenebene aufweist.The invention relates to a rectangular air outlet for room air conditioning systems for connection to a supply air duct in the ceiling area of a room, which air outlet has guide elements that run perpendicular to its lateral boundaries for both vertical directions of the ceiling plane.

An mit einer Zuluftströmung beaufschlagte Zuluftkanäle angeschlossene Luftaustritte der genannten Art - siehe z.B. CH-PS 301 735 -, die im allgemeinen mit ihrer Längsseite parallel zum Luftkanal gerichtet sind, enthalten, in Strömungsrichtung der aus ihnen austretenden luft gesehen, zunächst querstehende Leitelemente und daran anschliessend Leitelemente, die parallel zu ihren Längsseiten verlaufen. Die querstehenden, sogenannten "Gleichrichter" haben dabei primär die Aufgabe, durch Abbremsung der Geschwindigkeitskomponente in Richtung des Zuluftkanals über die "Länge" des Luftauslasses eine weitgehend gleichmässige Luftverteilung zu erhalten und eine Stauung in der Luft am stromabwärtigen Ende des Auslasses zu verhindern.Air outlets of the type mentioned connected to supply air ducts charged with a supply air flow - see e.g. CH-PS 301 735 -, which are generally directed with their long side parallel to the air duct, contain, seen in the direction of flow of the air emerging from them, initially transverse guide elements and then guide elements which run parallel to their long sides. The transverse, so-called "rectifiers" primarily have the task of maintaining a largely uniform air distribution by braking the speed component in the direction of the supply air duct over the "length" of the air outlet and of preventing congestion in the air at the downstream end of the outlet.

Die Verteilung quer zu Luftauslass und Zuluftkanal übernehmen die nachfolgenden, in Längsrichtung des Auslasskanals verlaufenden Leitelemente. Diese sind dafür bisher als starre oder verstellbare Schaufeln ausgebildet, deren Austrittskanten mindestens nahezu im Niveau der Decke liegen.The distribution transverse to the air outlet and supply air duct is carried out by the following guide elements running in the longitudinal direction of the outlet duct. So far, these have been designed as rigid or adjustable blades, the trailing edges of which are at least almost at the level of the ceiling.

Es hat sich gezeigt, dass mit den bekannten Luftauslässen eine Querverteilung nur unzulänglich erreicht wird, und dass eine Beeinflussung der Richtung und Reichweite besonders der äusseren Strahlen kaum möglich ist, die bei Vorhandensein einer Decke aufgrund des Coanda-Effekts häufig entlang der Decke verlaufen.It has been shown that with the known air outlets a transverse distribution is achieved only inadequately, and that it is hardly possible to influence the direction and range of the outer rays in particular, which often run along the ceiling due to the Coanda effect due to the presence of a ceiling.

Aufgabe der Erfindung ist es, die Querverteilung besonders von grossen Luftmengen - d.h. von Mengen über 1500 m 3/h - in Richtung und Reichweite zu verbessern. Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die in Strömungsrichtung der Luft nachgeordneten und unterhalb der Austrittsebene liegenden Leitelemente als mit zwei unter einem Winkel ungleich 11 an einer Achse angesetzten Flügeln versehene Lamellen ausgebildet sind, die durch Drehung um ihre Achsen in einer bestimmten Stellung der Flügel fixierbar sind. Bei Anordnungen, bei denen eine Doppeldecke vorhanden ist, ist die Austrittsebene im allgemeinen die Deckenebene; bei Anlagen ohne Doppeldecke entspricht die Austrittsebene der Ebene, in der der Boden des Zuluftkanals liegt.The object of the invention is to achieve the transverse distribution, particularly of large amounts of air - i.e. of quantities over 1500 m 3 / h - to improve in direction and range. According to the invention, this object is achieved in that the guide elements arranged downstream of the air and below the exit plane are designed as lamellae provided with two vanes attached to an axis at an angle not equal to 11, which by rotating about their axes in a specific position of the vanes are fixable. For arrangements where there is a double ceiling, the exit level is generally the ceiling level; in systems without a double ceiling, the outlet level corresponds to the level in which the floor of the supply air duct is located.

Die zweiflügelige Ausbildung der Lamellen und die Winkelstellung ermöglichen beispielsweise eine gleichmässige Verteilung der aus dem Luftauslass austretenden Luft über den ganzen Raum, wobei - bei Vorhandensein einer Doppeldecke - die äusseren Strahlen im allgemeinen infolge des Coanda-Effekts an der Decke entlangfliessen; andererseits können die äusseren Strahlen durch eine entsprechend "steile" Stellung der äusseren Lamellen bei solchen Anlagen von der Decke gelöst werden, so dass die gesamte Zuluft, mehr oder weniger weit aufgefächert, im wesentlichen in einen relativ engen Bereich des Raumes strömt.The two-wing design of the lamellae and the angular position enable, for example, a uniform distribution of the air emerging from the air outlet over the entire room, whereby - in the presence of a double ceiling - the outer rays generally flow along the ceiling due to the Coanda effect; on the other hand, the outer jets can be detached from the ceiling by such a "steep" position of the outer slats in such systems, so that the entire supply air, more or less fanned out, essentially flows into a relatively narrow area of the room.

Eine gleichmässige und - zu einer zum Zuluftkanal parallelen Mittelebene des Luftauslasses - symmetrische Verteilung der Luft lässt sich erreichen, wenn äussere, mittlere und zentrale Lamellen vorgesehen sind, die spiegelbildlich zu einer, zu ihren Achsen parallelen Mittelebene angeordnet und eingestellt sind, wobei die Lamellen von der Mittelebene aus nach beiden Seiten mit dem kleineren Winkel der Flügel nach aussen gerichtet sind. Selbstverständlich sind gegebenenfalls auch unsymmetrische Luftverteilungen - beispielsweise bei nahe einer Wand befindlichen Luftauslässen - möglich.A uniform and - to a central plane of the air outlet parallel to the supply air duct - symmetrical distribution of the air can be achieved if external, central and central fins are provided, which are arranged and set in mirror image to a central plane parallel to their axes, the fins from the middle plane are directed outwards on both sides with the smaller angle of the wings. Of course, asymmetrical air distributions are also possible, for example, in the case of air outlets located near a wall.

Bei bekannten Luftauslässen, bei denen die Luftstrahlen nach beiden Seiten über den ganzen Raum aufgespreizt werden, bereitet die Stabilität des zentralen Luftstrahls häufig Schwierigkeiten, da dieser leicht unkontrolliert nach einer Seite ausgelenkt wird und, je nach örtlichen und momentanen Strömungszuständen, in seiner Auslenkung von einer Seite auf die andere wechselt. Die Stabilität des zentralen Strahls lässt sich entscheiderdverbessern, wenn zwischen den nahe der Mittelebene gelegenen zentralen Lamellen stromabwärts ihres engsten Querschnitts eine Schikane angeordnet ist, wobei die Summe der zwischen der Schikane und den Lamellen verbleibenden Minimalquerschnitte kleiner ist als der engste Querschnitt zwischen den beiden Lamellen.In known air outlets, in which the air jets are spread over the entire space on both sides, the stability of the central air jet often causes difficulties, since it is deflected uncontrollably to one side and, depending on local and current flow conditions, in its deflection by one Side to side changes. The stability of the central beam can be improved decisively if a baffle is arranged between the central lamellae, which are located near the central plane, downstream of their narrowest cross section, the sum of the minimum cross sections remaining between the baffle and the lamellae being smaller than the narrowest cross section between the two lamellae.

Um die Luftstrahlen im zentralen Bereich, d.h. diejenigen innerhalb eines relativ engen Oeffnungswinkels vertikal unter dem Luftauslass, in Breite und Intensität variieren zu können, ist es vorteilhaft, wenn zwischen äusseren und zentralen Lamellen angeordnete mittlere Lamellen parallel zur Austrittsebene verschiebbar sind; ein Versetzen dieser mittleren Lamellen in verschiedene Niveauebenen relativ zur Austrittsebene kann eine Aenderung in der Oeffnungsbreite vor allem der im wesentlichen horizontalen äusseren Strahlen bewirken.In order to be able to vary the width and intensity of the air jets in the central area, ie those within a relatively narrow opening angle vertically below the air outlet, it is advantageous if middle slats arranged between outer and central slats can be displaced parallel to the exit plane; moving these middle slats to different levels planes relative to the exit plane can cause a change in the opening width, especially of the essentially horizontal outer rays.

Schliesslich bringt es Vorteile in der Strömungsführung und für die Fabrikation, wenn die Flügel der Lamellen ungleich breit sind, wobei der in Luftströmungsrichtung erste Flügel verkürzt ist.Finally, there are advantages in flow guidance and for manufacturing if the wings of the lamellae are unequal in width, the first wing being shortened in the direction of air flow.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels im Zusammenhang mit der Zeichnung näher erläutert.

  • Fig. 1 ist schematisch ein Schnitt senkrecht zum Zuluftkanal durch einen, in einer Decke eingelassenen Luftauslass;
  • Fig. 2 ist der Schitt II-II von Fig. l.
The invention is explained in more detail below using an exemplary embodiment in conjunction with the drawing.
  • Fig. 1 is a schematic section perpendicular to the supply air duct through an air outlet embedded in a ceiling;
  • Fig. 2 is the step II-II of Fig. L.

Der Zuluftkanal 1 (Fig. 1), der senkrecht zur Bildebene der Fig. 1 oberhalb der Austrittsebeneoder Decke 2 verläuft, hat in seinem Boden 3 eine der Grösse des Luftauslasses 4 angepasste Oeffnung 5, an die ein Verbindungsstutzen 6 angesetzt ist. Dieser dient dazu, bei industrieller Vorfertigung der Luftauslässe 4 unterschiedliche Abstände zwischen der Decke 2 und dem Zuluftkanal 1 auszugleichen, indem der Luftauslass 4 mehr oder weniger weit in den Verbindungsstutzen 6 eingeschoben wird.The supply air duct 1 (FIG. 1), which runs perpendicular to the image plane of FIG. 1 above the exit plane or ceiling 2, has in its base 3 an opening 5 adapted to the size of the air outlet 4, to which a connecting piece 6 is attached. This serves to compensate for different distances between the ceiling 2 and the supply air duct 1 in industrial prefabrication of the air outlets 4, in that the air outlet 4 is pushed more or less far into the connecting piece 6.

Der Luftauslass 4, der aus einem rechteckigen hohlkastenartigen Mantelblech besteht, ist an seinem oberen Ende mit einem Lochblech 7 abgedeckt; parallel zu seiner Breitseite verlaufende, fest eingebaute Leitelemente 8 unterteilen den Luftauslass 4 in in Längsrichtung hintereinanderliegende Kammern 9.The air outlet 4, which consists of a rectangular hollow box-like casing sheet, is covered at its upper end with a perforated sheet 7; Fixed built-in guide elements 8 running parallel to its broad side divide the air outlet 4 into chambers 9 lying one behind the other in the longitudinal direction.

Durch die Leitelemente 8, die mit Vorteil bis etwa auf das Niveau der Decke 2 heruntergezogen sind, wird die Geschwindigkeitskomponente der Luft in Richtung der Strömung im Zuluftkanal 1 vernichtet und eine gleichmässige Luftverteilung über die Längsrichtung des Luftauslasses 4 erreicht.By means of the guide elements 8, which are advantageously pulled down to approximately the level of the ceiling 2, the speed component of the air in the direction of the flow in the supply air duct 1 is destroyed and a uniform air distribution over the longitudinal direction of the air outlet 4 is achieved.

Während die Längsseiten des Mantels nach zweimaligem Abwinkeln um 90° am Zuluftkanal 2 aufgehängt sind und dabei einen, zwischen Decke 2 und Luftauslass 4 verbleibenden Spalt abdecken, ragen die Schmalseiten 10 des Luftauslasses 4 ein Stück weit in den Raum hinein. Ueber die Breite des Luftauslasses 4 verteilt sind,nahe der Unterkante 11, in den Schmalseiten 10 Lamellen gelagert, die mit ihren Achsen 12 in ihrer Winkelstellung einstellbar und durch Schraubverbindungen 15 (Fig. 2) in einer gewünschten Winkelstellung fixiert sind. Die Lamellen bestehen aus zwei unter einem Winkel ungleicher zueinander stehenden Flügeln 13, die an die Achsen 12 angesetzt sind.While the long sides of the casing are suspended from the supply air duct 2 after being bent twice by 90 ° and thereby cover a gap remaining between the ceiling 2 and the air outlet 4, the narrow sides 10 of the air outlet 4 protrude a little into the room. Spread over the width of the air outlet 4, near the lower edge 11, 10 slats are mounted in the narrow sides, which can be adjusted in their angular position with their axes 12 and are fixed in a desired angular position by screw connections 15 (FIG. 2). The lamellae consist of two wings 13 which are at an angle which are more unequal to one another and which are attached to the axes 12.

Die Anordnung der Lamellen ist beiderseits einer Längsmittelebene 14 des Luftauslasses 4 spiegelsymmetrisch, wobei die einzelnen Lamellen in Ebenen unterschiedlichen Abstandes zur Decke 2 liegen. Die Lamellen sind dabei so gerichtet, dass der kleinere Flügelwinkel nach aussen zeigt. Aus fabrikatorischen Gründen sind alle Lamellen in ihren Abmessungen gleich. Weiterhin ist jedoch die Breite der "inneren" Flügel 13 geringer als diejenige der "äusseren" Flügel 13. Dadurch ergibt sich eine Materialersparnis bei den aus Aluminium gefertigten Lamellen, sowie in Höhe geringerer Platzbedarf im Innern des Luftauslasses.The arrangement of the slats is mirror-symmetrical on both sides of a longitudinal center plane 14 of the air outlet 4, the individual slats lying in planes of different distances from the ceiling 2. The slats are aligned so that the smaller wing angle points outwards. For manufacturing reasons, all slats are the same in their dimensions. Furthermore, however, the width of the "inner" wings 13 is less than that of the "outer" wings 13. This results in a material saving in the slats made of aluminum, and in the amount of space required inside the air outlet.

Zwischen den, den Zentralstrahl führenden inneren oder zentralen Lamellen, deren engster horizontaler Querschnitt im Bereich ihrer Achsen 12 mit a bezeichnet ist, ist nach unten versetzt eine als Rundstab ausgebildete Schikane 16 vorgesehen; der Rundstab 16 und die Achsen 12 der Lamellen sind dabei zueinander so angerodnet, dass der Abstand a grösser ist als die Summe der Abstände b zwischen dem Rundstab 16 und je einer der Achsen 12. Auf diese Weise erfährt die Strömung des Zentralstrahles im Bereich des Rundstabs 16 eine Beschleunigung, durch die ihre Stabilisierung verbessert wird, so dass ein stabiler, zur Mittelebene 14 symmetrischer Vertikalstrahl gewährleistet ist.Between the central beam leading inner or central slats whose narrowest horizontal cross section is referred to in the area of its axis 12 a, is offset downwards designed as a round rod S chikane 16 is provided; The round rod 16 and the axes 12 of the lamellae are arranged in such a way that the distance a is greater than the sum of the distances b between the round rod 16 and one of the axes 12. In this way, the flow of the central jet in the region of the round rod is experienced 16 an acceleration by means of which its stabilization is improved, so that a stable vertical beam which is symmetrical with respect to the central plane 14 is ensured.

Wie Fig. 1 zeigt, sind für die Lagerung der mittleren Lamellen in den Schmalseiten 10 Langlöcher 17 vorgesehen, so dass diese Lamellen in horizontaler Richtung verschoben werden können, womit vor allem die an den Aussenseiten der zentralen Lamellen entlang strömenden Teile des Zentralstrahls in ihrer Breite und damit in ihrer Intensität variiert werden können.As shown in FIG. 1, 10 slots 17 are provided for the storage of the middle slats in the narrow sides, so that these slats can be displaced in the horizontal direction, with the width of the parts of the central jet flowing along the outside of the central slats in particular and can thus be varied in intensity.

Schliesslich sind für die mittleren Lamellen zwei Langlöcher 17 vorhanden, die in unterschiedlichen Niveauhöhen zu den Ebenen der anderen Lamellen liegen. Durch ein Versetzen der mittleren Lamellen in vertikaler Richtung kann vor allem die Oeffnung der zur Seite aufgespreizten, .im wesentlichen horizontalen Strahlen geändert werden, womit ihre Reichweite an die seitlichen Raumabmessungen und/oder an Unterschiede in den zur Verfügung stehenden Luftvolumina angepasst werden kann.Finally, there are two elongated holes 17 for the middle slats, which are at different levels to the levels of the other slats. By displacing the central slats in the vertical direction, the opening of the, essentially horizontal, beams spread apart to the side can be changed, so that their range can be adapted to the lateral room dimensions and / or to differences in the available air volumes.
