Description

Die Erfindung betrifft eine Luftzuführvorrichtung, bestehend aus einem Luftanschlußkasten und mindestens einem über den Luftanschlußkasten an einen Luftkanal anschließbaren Luftdurchlaß, mit dem Luft wahlweise mehr oder weniger vertikal bzw. horizontal in einen zu belüftenden Raum einleitbar ist.The invention relates to an air supply device consisting of a Air connection box and at least one over the air connection box to one Air duct connectable air outlet, with the air either more or can be introduced less vertically or horizontally into a room to be ventilated.

Derartige Luftzuführvorrichtungen sind allgemein bekannt und erfordern, zwischen dem Luftkanal und den Luftdurchlässen dann Luftanschlußkästen zwischenzuschalten, wenn ein unmittelbarer Anschluß der Luftdurchlässe an den Luftkanal aus Platzmangel nicht möglich ist oder aus optischen Gründen unerwünscht ist.Such air supply devices are generally known and require between then interpose air connection boxes between the air duct and the air outlets, if a direct connection of the air outlets to the Air duct is not possible due to lack of space or undesirable for optical reasons is.

Um die Bauhöhe einer mit einem Luftanschlußkasten ausgestatteten Luftzuführvorrichtung gering zu halten, ist es gleichfalls allgemein bekannt, den Luftdurchlaß jeweils innerhalb des Luftanschlußkastens zu plazieren. Dadurch vergrößert sich allerdings das Volumen des Luftanschlußkastens, was zu einer Verteuerung der Gesamtkonstruktion der Luftzuführvorrichtung führt.To the height of an air supply device equipped with an air connection box to keep it low, it is also generally known to keep the air passage to be placed inside the air connection box. This enlarges however, the volume of the air connection box, leading to an increase in price of the overall construction of the air supply device.

Aus der CH-A-648923 A5 ist ein Drahllauslaß bekannt, der aus einem Außenrohr und einem darin konzentrisch angeordneten Kernrohr besteht. Hierbei handelt es sich um einen klassischen Drallauslaß, der entweder direkt mit einem Zuluftkanal verbunden oder mit Hilfe eines Luftverteilkastens und beispielsweise einem zwischen diesem und dem Drallauslaß angeordneten flexiblen Rohr an ein Kanalnetz angeschlossen werden kann. Je nach der gewählten Anschlußart gelangt die Luft aus dem Anschlußkasten oder direkt aus dem Zuluftkanal in den Auslaß. In keinem Fall ist jedoch die Aufteilung des Zuluftvolumenstroms vor dem Drallauslaß möglich. From CH-A-648923 A5 a wire outlet is known which consists of an outer tube and a core tube arranged concentrically therein. This is what it is about is a classic swirl outlet, which is either directly connected to a supply air duct connected or with the help of an air distribution box and for example one arranged between this and the swirl outlet flexible pipe Sewer network can be connected. Depending on the connection type selected the air enters the connection box or directly from the supply air duct Outlet. In no case, however, is the distribution of the supply air volume flow the swirl outlet possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Luftzuführvorrichtung der eingangs beschriebenen Art vorzuschlagen, die es ermöglicht, den jeweiligen Luftdurchlaß und damit auch den Luftanschlußkasten wesentlich zu verkleinern, ohne dadurch eine Reduzierung des in den zu belüftenden Raumes mit jeder Zuführvorrichtung einbringbaren Volumenstromes zu verursachen.The invention has for its object an air supply device of the beginning to propose the type described, which enables the respective To significantly reduce air passage and thus also the air connection box, without thereby reducing the space to be ventilated with everyone To cause feeder introduced volume flow.

Da der Anschlußkasten an sich dicht ausgeführt ist, läßt sich der für die Luftzuführvorrichtung insgesamt bestimmte Volumenstrom so aufteilen, daß der Luftdurchlaß nur noch mit einem Teilvolumenstrom beaufschlagt wird und ein restlicher Teilvolumenstrom durch die Perforationen im Luftanschlußkasten unmittelbar in den Raum eingeleitet wird. Infolgedessen kann der entsprechend geringer beaufschlagte Luftdurchlaß eine kleine Baugröße erhalten. Dadurch reduzieren sich die Kosten für den Luftdurchlaß und somit auch die Kosten für die Gesamtkonstruktion der Luftzuführvorrichtung, zumal auch der Luftanschlußkasten entsprechend kleiner dimensioniert werden kann, was sich gleichfalls kostensparend auswirkt.Since the junction box is designed to be sealed, it can be used for the air supply device divide the total volume flow so that the air passage only a partial volume flow is applied and a remaining one Partial volume flow through the perforations in the air connection box immediately is introduced into the room. As a result, it can be correspondingly lower air passage get a small size. This will reduce the cost of air passage and thus the cost of the overall construction the air supply device, especially the air connection box can be dimensioned correspondingly smaller, which also saves costs affects.

Durch diese Ausgestaltung läßt sich durch die jeweils gewählte Strömungsrichtung des über den Luftdurchlaß in den Raum eingebrachten Teilvolumenstromes die Strömungsrichtung des über die Perforationen im Luftanschlußkasten in den Raum eingeleiteten Teilvolumenstromes beeinflussen. This configuration allows the flow direction selected in each case of the partial volume flow introduced into the room via the air outlet the direction of flow of the perforations in the air connection box influence the partial volume flow introduced into the room.

Nach weiteren Ausgestaltungen der Erfindung sind die Perforationen im kreisscheibenförmigen Bodenteil des Luftanschlußkastens über einen radial außenliegenden Bereich und die Perforationen im zylindrischen Wandteil des Luftanschlußkastens über einen unteren, am Bodenteil des Luftanschlußkastens angeschlossenen Bereich verteilt angeordnet.According to further embodiments of the invention, the perforations are circular Bottom part of the air connection box over a radially outer Area and the perforations in the cylindrical wall part of the air connection box via a lower one, connected to the bottom part of the air connection box The area is distributed.

Um das Aufteilungsverhältnis der Teilvolumenströme zu beeinflussen, sieht eine weitere Ausgestaltung der Erfindung vor, daß oberhalb der Perforationen im Luftanschlußkasten mindestens eine den Innenraum des Luftanschlußkastens unterteilende, gleichfalls mit Perforationen versehene Trennwand angeordnet ist.One sees to influence the distribution ratio of the partial volume flows further embodiment of the invention that above the perforations in Air connection box at least one the interior of the air connection box dividing, also provided with perforations partition is arranged.

Vorzugsweise besteht eine solche mit Perforationen versehene Trennwand aus einer sich über den horizontalen Querschnitt des Luftanschlußkastens erstrekkenden Ringscheibe.Such a perforated partition preferably consists of one extending over the horizontal cross section of the air connection box Washer.

Schließlich sieht eine Ausgestaltung der Erfindung noch vor, daß eine mit Perforationen versehene Trennwand aus einem Zylinder besteht, der mit einem unteren Rand an einen Rand einer Einlaßöffnung des Luftdurchlasses und mit einem oberen Rand an eine Deckenseite des Luftanschlußkastens angeschlossen ist.Finally, an embodiment of the invention provides that one with perforations provided partition consists of a cylinder that with a lower edge to an edge of an inlet opening of the air passage and with an upper edge connected to a ceiling side of the air connection box is.

Die aus einem mit Perforationen versehnen Zylinder gebildete Trennwand vergleichmäßigt insbesondere die Anströmung des Luftdurchlasses und verbessert dessen Akustik.The partition formed from a cylinder with perforations is evened out especially the flow to the air outlet and improved its acoustics.
