Description

Die Erfindung betrifft eine Vorrichtung zum Einleiten von Luft aus Lüftungs- oder Klimaanlagen in Gebäuderäume, bestehend aus einem Gehäuse mit einem den Luftstrom düsenförmig bündelnden Ausblaskanal und mit verstellbaren Leitschaufeln im Luftstrom.The invention relates to a device for introducing air from ventilation or air conditioning systems into building rooms, consisting of a housing with a blow-out duct bundling the air flow and with adjustable guide vanes in the air flow.

Bei Fabrikhallen oder auch anderen Gebäuderäumen wird die Zuluft zum Beispiel aus einem Dachklimagerät üblicherweise an der Raumdecke mittels eines Luftverteilers eingeleitet. Hierzu sind zum Beispiel aus den US-PS'en 2 053 403 und 3 165 052 Luftverteiler bekannt, die die Richtung des austretenden gebündelten Luftstrahles mit verstellbaren Leitschaufeln am Luftverteileraustritt oder mit einer in der Ausblasrichtung verstellbaren Düse des Luftverteilers verändern können. In der Praxis sind auch sogenannte Drall-Luftverteiler angewendet worden, die einen rotierenden, tangential die Dralleinrichtung verlassenden Luftstrom erzeugen; bei einigen dieser Drall-Luftverteiler tritt der gesamte rotierende Zuluftstrom tangential und nur horizontal in den Gebäuderaum aus; bei anderen dieser Drall- Luftverteiler tritt die Zuluft teils durch eine normale Düse als Strahl und teils tangential-horizontal aus und kann durch unterschiedliche Durchströmungsmenge und Mengenaufteilung der Zuluft eine Veränderung der Richtung und der Verteilung der ausströmenden Zuluft vorgenommen werden.In factory buildings or other building spaces, for example, the supply air is usually introduced from a roof air conditioner on the ceiling using an air distributor. For this purpose, air distributors are known, for example, from US Pat. Nos. 2,053,403 and 3,165,052, which can change the direction of the emerging bundled air jet with adjustable guide vanes at the air distributor outlet or with a nozzle of the air distributor that is adjustable in the blow-out direction. In practice, so-called swirl air distributors have been used, which generate a rotating air flow tangentially leaving the swirl device; with some of these swirl air distributors, the entire rotating supply air flow emerges tangentially and only horizontally into the building space; in other of these swirl air distributors, the supply air emerges partly through a normal nozzle as a jet and partly tangentially horizontally, and a change in the direction and distribution of the outgoing supply air can be carried out by varying the flow rate and the distribution of the quantities of the supply air.

An Luftverteiler zum Einleiten von Luft an der Gebäuderaumdecke wird die Anforderung gestellt, dass einerseits die Zuluft insbesondere beim Einleiten von kühler Frischluft weitgehend zugfrei in die Aufenthaltszone eingebracht werden kann, was bei kleineren Gebäuderaumhöhen eine stärkere Horizontalverteilung erfordert als bei grösseren Gebäuderaumhöhen, und dass andererseits beim Raumbeheizungsfall und insbesondere auch bei grösseren Gebäuderaumhöhen ein Warmluftstrahl direkter den Aufenthaltsbereich erreichen kann.Air distributors for introducing air to the ceiling of the building have the requirement that, on the one hand, the supply air can be brought into the lounge zone largely draft-free, especially when cool fresh air is introduced, which requires a greater horizontal distribution for smaller building heights than for larger building heights, and that In case of room heating, and especially with larger building room heights, a hot air jet can reach the lounge area more directly.

Die Erfindung hat sich deshalb die Aufgabe gestellt, eine Vorrichtung der eingangs genannten Art so zu verbessern, dass bei einfacher Ausbildung und einfacher Verstellbarkeit die Zuluftausblasung stufenlos von einem gebündelten konzentrierten Vertikalstrahl über einen breiter gefächerten glockenförmigen Luftstrom bis zu einer im wesentlichen rein horizontalen Abströmung verändert werden kann.The object of the invention is therefore to improve a device of the type mentioned at the outset such that, with a simple design and simple adjustability, the supply air blow-out can be changed continuously from a concentrated vertical jet via a broader bell-shaped air flow to an essentially purely horizontal outflow can.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass in dem Gehäuse ein scheibenförmiger, radial vom Randbereich zum Mittelbereich durchströmender Drallkanal ausgebildet ist, in dem die Leitschaufeln kranzförmig angeordnet sind und zwischen einer radialen und einer wenigstens nahezu tangentialen Stellung verstellbar sind, dass sich an den Mittelbereich des Drallkanals in Richtung seiner Drallachse ein Düsenkanal anschliesst, der eintrittsseitig von einer trichterförmigen Gehäuseerweiterung gebildet ist, und dass mit einem axialen Abstand in Strömungsrichtung hinter dem Austrittsöffnungsrand der Gehäuseerweiterung ein Verteilring mit einer Mittelöffnung angeordnet ist, der mit einem Teil seiner radialen Erstreckung den Austrittsquerschnitt der Gehäuseerweiterung überdeckt.This object is achieved according to the invention in that a disk-shaped swirl channel, flowing radially from the edge region to the central region, is formed, in which the guide vanes are arranged in a ring shape and can be adjusted between a radial and an at least almost tangential position such that the central region of the Swirl duct connects a nozzle duct in the direction of its swirl axis, which is formed on the inlet side by a funnel-shaped housing extension, and that with an axial distance in the direction of flow behind the outlet opening edge of the housing extension, a distribution ring is arranged with a central opening, which, with part of its radial extension, has the outlet cross section of the housing extension covered.

Ausbildung und Wirkungsweise der erfindungsgemässen Vorrichtung werden nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. Es zeigenThe design and mode of operation of the device according to the invention are described in more detail below with reference to an embodiment shown in the drawing. Show it

Figur 1 die Vorrichtung in einem axialen Längsschnitt, Figur 2 und 3 die Vorrichtung in vereinfachter Darstellung mit Luftabströmungen bei anderen Verstellungen der Vorrichtung.Figure 1 shows the device in an axial longitudinal section, Figure 2 and 3, the device in a simplified representation with air flows in other adjustments of the device.

In dem Gehäuse 1 der Vorrichtung, in das die Luft von oben her axial eintritt, ist ein scheibenförmiger Drallkanal 8 ausgebildet, der radial vom Randbereich zum Mittelbereich durchströmt wird. In dem Drallkanal 8 sind kranzförmig Leitschaufeln 2 angeordnet, die radial ausgerichtet sind und durch eine Regelscheibe 3 und eine Verstelleinrichtung 4 in eine wenigstens nahezu tangentiale Stellung verstellbar sind. An den Mittelbereich des Drallkanals 8 schliesst sich in Richtung der Drallachse des Drallkanals ein Düsenkanal 9 an, der eintrittsseitig von einer trichterförmigen Gehäusedüse 5 und austrittsseitig von einer trichterförmigen Gehäuseerweiterung 6 gebildet ist. Mit einem axialen Abstand vor dem Austrittsöffnungsrand 10 der Gehäuseerweiterung 6 ist ein eine Mittelöffnung 11 enthaltender Verteilring 7 angeordnet, dessen Aussenrandkreisdurchmesser und Innenrandkreisdurchmesser so bemessen sind, dass der Verteilring mit einem Teil seiner radialen Erstreckung den Austrittsquerschnitt der Gehäuseerweiterung 6 im Bereich des Austritts- öffnungsrandes 10 überdeckt und die an der Wandung der Gehäuseerweiterung 6 entlang strömende Luft auf den Verteilring 7 auftreffen kann.In the housing 1 of the device, into which the air enters axially from above, a disk-shaped swirl channel 8 is formed, which is flowed through radially from the edge area to the central area. In the swirl channel 8, vane-shaped guide vanes 2 are arranged, which are aligned radially and can be adjusted into an at least almost tangential position by means of a regulating disk 3 and an adjusting device 4. A nozzle channel 9, which is formed on the inlet side by a funnel-shaped housing nozzle 5 and on the outlet side by a funnel-shaped housing extension 6, adjoins the central region of the swirl duct 8 in the direction of the swirl axis of the swirl duct. Arranged at an axial distance in front of the outlet opening edge 10 of the housing extension 6 is a distribution ring 7 containing a central opening 11, the outer edge circle diameter and inner edge circle diameter of which are dimensioned such that the distribution ring, with part of its radial extension, corresponds to the outlet cross section of the housing extension 6 in the region of the outlet opening edge 10 covers and the air flowing along the wall of the housing extension 6 can strike the distribution ring 7.

Bei radialer Ausrichtung der Leitschaufeln 2 erhält die Luft beim Durchströmen des Drallkanals 8 keine Drallkomponente. Der Luftstrom wird in der Gehäusedüse 5 beschleunigt und reisst beim Durchströmen des engsten Querschnittes der Gehäuseerweiterung 6 aufgrund der nur vorhandenen axialen Strömungskomponente von der Wandung der Gehäuseerweiterung 6 ab, so dass die Luft, wie in Figur 1 dargestellt, hauptsächlich durch die Mittelöffnung 11 des Verteilringes 7 strömt und die Vorrichtung als gebündelten Luftstrahl mit der maximalen Wurfweite verlässt. Durch graduelles Verstellen der Leitschaufeln 2 in Richtung einer tangentialen Stellung wird dem Luftstrom beim Durchströmen des Drallkanals 8 eine kontinuierlich variierbare Drallkomponente überlagert. Die Drallenergie bewirkt mit zunehmender Grösse, dass die Luftströmung nach der Gehäusedüse 5 sich zunehmend an die Gehäuseerweiterung 6 anlegt und dadurch glockenförmig verbreitert, wie in Figur 2 dargestellt ist. Hierbei trifft der Luftstrom in grösser werdendem Ausmass auf den Verteilring 7 auf, der teils durch seine Mittelöffnung 11 und teils auf seiner Aussenseite umströmt wird und den Übergangsbereich vom konzentrierten Vertikalstrahl der Figur 1 zu der in Figur 3 dargestellten, nahezu rein horizontalen Abströmung der Luft bei stärkster Tangentialstellung der Leitschaufeln 2 und stärkster Drallkomponente vergrössert. Nur durch Verstellen der Leitschaufeln 2, welches in Abhängigkeit von der Zulufttemperatur und der Raumtemperatur und durch Regeln des Stellmotors 4 oder auch durch einen selbsttätigen Mechanismus erfolgen kann, kann die Lufteinbringung von einem gebündelten Luftstrahl bis zu einer praktisch horizontalen Abströmung variiert werden, wobei sowohl im Raumbeheizungsfall die gesamte Zuluftmenge als konzentrierter Vertikalstrahl die Vorrichtung verlässt und dadurch die grösstmögliche Wurfweite erreicht werden kann als auch im Belüftungsfall die gesamte Zuluftmenge horizontal und für die Aufenthaltszone zugfrei eingeleitet werden kann. Die mit dem Leitring 7 bewirkte Vergrösserung des Bereichs der ZwischensteIlungen mit mehr oder weniger glockenförmiger Luftverteilung ergibt einerseits eine Erhöhung der Komfortbedingungen, zum Beispiel je nach Höhe des Gebäuderaumes, und erlaubt andererseits, dass die Zuluft zur Energieeinsparung immer nur mit der minimal notwendigen Temperatur eingeleitet werden kann.If the guide vanes 2 are aligned radially, the air receives no swirl component when flowing through the swirl duct 8. The air flow is accelerated in the housing nozzle 5 and, when flowing through the narrowest cross section of the housing extension 6, tears off from the wall of the housing extension 6 due to the only axial flow component present, so that the air, as shown in FIG. 1, mainly through the central opening 11 of the distribution ring 7 flows and leaves the device as a bundled air jet with the maximum throw. By gradually adjusting the guide vanes 2 in the direction of a tangential position, a continuously variable swirl component is superimposed on the air flow as it flows through the swirl duct 8. With increasing size, the swirl energy causes the air flow after the housing nozzle 5 to increasingly contact the housing extension 6 and thereby widen it in a bell shape, as shown in FIG. 2. Here, the air stream hits the distribution ring 7 to an increasing extent, which is flowed around partly through its central opening 11 and partly on its outside, and the transition region from the concentrated vertical jet of FIG. 1 enlarged to the almost purely horizontal outflow of air shown in Figure 3 with the strongest tangential position of the guide vanes 2 and strongest swirl component. Only by adjusting the guide vanes 2, which can take place depending on the supply air temperature and the room temperature and by regulating the servomotor 4 or also by an automatic mechanism, can the introduction of air be varied from a concentrated air jet to a practically horizontal outflow, both in In the case of room heating, the entire supply air quantity leaves the device as a concentrated vertical jet and the largest possible throw distance can be achieved as well as in the case of ventilation, the entire supply air quantity can be introduced horizontally and draft-free for the occupied zone. The enlargement of the area of the intermediate parts with more or less bell-shaped air distribution caused by the guide ring 7 results on the one hand in an increase in comfort conditions, for example depending on the height of the building space, and on the other hand allows the supply air to be saved only at the minimum necessary temperature in order to save energy can.
