Definitions
- the invention relates to a ceiling outlet for air volume flows in rooms for heating and / or cooling purposes with a connecting piece to a corresponding air supply line, the connecting piece either being round in cross section or expanding in a funnel shape and the connecting piece being fitted with a connecting plate with openings, which is assigned a rotatable perforated plate.
- Ceiling outlets of this type are known in a variety of forms, with depending on the design of the outlet a vertical or rather a horizontal delivery of the air volume flow is ensured. Furthermore, other embodiments of ceiling outlets have correspondingly adjustable slats, through which the volume flow can be throttled.
- the object of the present invention is to provide an inexpensive ceiling outlet which can be used both in high and in lower rooms and in which the volume flow can be regulated by simple structural elements.
- This constant volume flow controller always allows a constant air volume flow through regardless of the resistance.
- the degree of turbulence is also increased, so that the depths of penetration or throwing distances can be shortened considerably as a result. This means that with a constant Air volume flow, the depth of penetration into the room can be adjusted without great design effort.
- the perforated plate can, for example, be placed in front of the end plate, but it is preferably arranged in the interior of the connecting piece. Furthermore, the openings of the perforated plate will preferably match those of the end plate in order to achieve a controlled change in the cross section of the openings in the end plate. In the present exemplary embodiment, the openings are round, openings on a circle around a center always having a constant diameter, but the openings on the different circular paths also have different diameters.
- the perforated plate has an axis of rotation, which is preferably also the longitudinal axis of the connecting piece. Furthermore, this axis of rotation is naturally associated with a correspondingly manually operated or preferably electric drive, with which the perforated plate can be rotated.
- the cross section of the openings in the end plate is influenced by the rotation of the perforated plate in relation to the end plate, so that the air volume flow can be increased or decreased.
- the connecting piece can be designed in a funnel-shaped manner towards the end plate.
- a ceiling outlet shaped in this way can be used particularly for lower rooms, since the air streams are spread out more horizontally here.
- the connecting piece is equal to the outer diameter of the outlet, so that the air streams also emerge vertically into the room through the openings in the end plate.
- This ceiling outlet is particularly suitable for higher rooms because the air currents can penetrate deeper into the room.
- this ceiling outlet is architecturally pleasing and deviates from the usual outlet shapes. For example, it should also be usable in listed old buildings.
- the cross section of the openings in the end plate is influenced by the rotation of the perforated plate in relation to the end plate, so that the air volume flow can be increased or decreased.
- a ceiling outlet R consists of a connecting piece 1 or 1a.
- the round connecting piece 1a shown in dashed lines is intended to be used in particular in high rooms, since the air introduced therein is blown out essentially vertically, as indicated by the arrows 2a shown in dashed lines.
- the connecting piece 1 on the other hand, widens in a funnel shape and is therefore mainly used in lower rooms in which the air is blown out more horizontally, which in turn is indicated by the corresponding arrows 2.
- the connecting piece 1 connects not shown to a corresponding air line. To the room it is delimited by an end plate 3, which is penetrated by holes 4. In the exemplary embodiment shown, these holes 4 have different diameters.
- perforated plate 5 In the interior of the connecting piece 1 there is a further perforated plate 5, which is assigned to the end plate 3 in a position-related manner.
- This perforated plate 5 can be rotated, specifically in the present exemplary embodiment around the axis of rotation 6 indicated by the broken lines. Corresponding drive elements for rotating the perforated plate 5 are not shown.
- This perforated plate 5 can be used to intervene in a simple manner in the radiation behavior of the ceiling outlet R. It also serves to throttle the volume flow.
- the perforated plate 5 and the end plate 3 lie one above the other so that the openings 4 of the end plate 3 correspond to openings 7 of the perforated plate 5.
- the largest possible free cross section of the openings 4 of the end plate 3 is thus achieved. In this case, the greatest possible penetration depths are possible vertically and the largest throwing distances horizontally.
- the perforated plate 5 is now rotated, the configurations shown, for example, in FIGS. 3 and 4 are shown. The following is achieved: When the perforated plate 5 rotates, the free cross section of the openings 4 in the end plate 3 is reduced. This also increases the pressure loss and the volume flow decreases. This may be necessary, for example, when balancing a supply air line or when a single outlet has to be throttled. The latter is necessary for drafts.
- a constant volume flow controller 8 can also be used in front of the ceiling outlet R. This should always allow a constant volume flow of air to pass through regardless of the resistance. This achieves the following: By turning the perforated plate 5, the degree of turbulence is increased, so that the penetration depths or throwing distances are significantly reduced compared to the starting position shown in FIG. 2. This means that the penetration depth can be adapted to the room with a constant volume flow and without great effort.
- the appearance of the outlet remains architecturally responsive in all positions of the ceiling outlet R according to the invention and can therefore also be used, for example, in heritage-protected old buildings.

Abstract
Description
Die Erfindung betrifft einen Deckenauslaß für Luft-Volumenströme in Räume zu Heiz- und/oder Kühlzwecken mit einem Anschlußstutzen an eine entsprechende Luftzuleitung, wobei der Anschlußstutzen entweder im Querschnitt rund ausgebildet ist oder sich trichterförmig erweitert und wobei dem Anschlußstutzen eine Anschlußplatte mit Öffnungen vorgesetzt ist, welcher eine drehbare Lochplatte zugeordnet ist.The invention relates to a ceiling outlet for air volume flows in rooms for heating and / or cooling purposes with a connecting piece to a corresponding air supply line, the connecting piece either being round in cross section or expanding in a funnel shape and the connecting piece being fitted with a connecting plate with openings, which is assigned a rotatable perforated plate.
Derartige Deckenauslässe sind in vielfältiger Form bekannt, wobei je nach Ausbildung des Auslasses eher ein vertikales oder eher ein horizontales Ausbringen des Luft-Volumenstromes gewährleistet ist. Ferner besitzen andere Ausführungsbeispiele von Deckenauslässen entsprechend verstellbare Lamellen, durch welche der Volumenstrom gedrosselt werden kann.Ceiling outlets of this type are known in a variety of forms, with depending on the design of the outlet a vertical or rather a horizontal delivery of the air volume flow is ensured. Furthermore, other embodiments of ceiling outlets have correspondingly adjustable slats, through which the volume flow can be throttled.
Aus der US-A 1 755 784 ist ein Luftauslaß bekannt, bei dem einer gelochten Abschlußplatte eine Lochplatte drehbar zugeordnet ist. Diese Anordnung hat aber nur den Zweck, eine mengenmäßige Luftstromregelung in einen Raum durchzuführen. Durch sie kann weder ein vertikales noch ein horizontales Einblasen von Luft beeinflußt werden. Ferner ist aus der DE-U 18 02 396 ein Entlüftungseinsatz aus Kunststoff bekannt, der insbesondere an Speisekammern und ähnlichen Räumen in Gebäuden Verwendung findet. Der Speisekammer zugewandt ist eine durchlochte Scheibe, während nach außen eine weitere Scheibe mit einer drehbaren Abdeckscheibe versehen ist. Hierdurch kann die Belüftung reguliert werden, jedoch findet kein Beeinflussung eines Luftstromes in einen Raum statt, d.h., es wird weder dessen Eindringtiefe noch dessen vertikale oder horizontale Ausrichtung beeinflußt.From US-A 1 755 784 an air outlet is known in which a perforated plate is rotatably associated with a perforated end plate. However, this arrangement only has the purpose of carrying out quantitative air flow control in a room. Neither vertical nor horizontal air blowing can be influenced by them. Furthermore, from DE-U 18 02 396 a ventilation insert made of plastic is known, which is used in particular in pantries and similar rooms in buildings. A paned plate is facing the pantry, while another plate is provided with a rotatable cover plate on the outside. This allows ventilation to be regulated, but there is no influence on the air flow into a room, i.e. neither its penetration depth nor its vertical or horizontal orientation is affected.
Aufgabe der vorliegenden Erfindung ist es, einen preiswerten Deckenauslaß zu schaffen, welcher sowohl in hohen wie auch in niedrigeren Räumen einsetzbar ist und bei dem eine Regelung des Volumenstromes durch einfache konstruktive Elemente möglich ist.The object of the present invention is to provide an inexpensive ceiling outlet which can be used both in high and in lower rooms and in which the volume flow can be regulated by simple structural elements.
Zur Lösung dieser Aufgabe führt, daß dem Anschlußstutzen ein Konstant-Volumenstromregler vorgeschaltet ist.The solution to this problem is that a constant volume flow controller is connected upstream of the connecting piece.
Dieser Konstant-Volumenstromregler läßt immer unabhängig vom Widerstand einen gleichbleibenden Luft-Volumenstrom durch. Bei Veränderung des Querschnitts der Öffnungen in der Abschlußplatte wird dann auch der Turbulenzgrad erhöht, so daß hierdurch die Eindringtiefen bzw. Wurfweiten wesentlich verkürzt werden können. Dies bedeutet, daß bei einem gleichbleibenden Luft-Volumenstrom die Eindringtiefe in den Raum ohne großen konstruktiven Aufwand angepaßt werden kann.This constant volume flow controller always allows a constant air volume flow through regardless of the resistance. When the cross section of the openings in the end plate is changed, the degree of turbulence is also increased, so that the depths of penetration or throwing distances can be shortened considerably as a result. This means that with a constant Air volume flow, the depth of penetration into the room can be adjusted without great design effort.
Die Lochplatte kann beispielsweise der Abschlußplatte vorgesetzt sein, bevorzugt ist sie jedoch im Innern des Anschlußstutzens angeordnet. Ferner werden bevorzugt die Öffnungen der Lochplatte mit denjenigen der Abschlußplatte übereinstimmen, um so eine geregelte Veränderung des Querschnitts der Öffnungen in der Abschlußplatte zu erzielen. Im vorliegenden Ausführungsbeispiel sind die Öffnungen rund, wobei Öffnungen auf einem Kreis um einen Mittelpunkt herum immer einen gleichbleibenden Durchmesser besitzen, jedoch die Öffnungen auf den unterschiedlichen Kreisbahnen auch unterschiedliche Durchmesser haben.The perforated plate can, for example, be placed in front of the end plate, but it is preferably arranged in the interior of the connecting piece. Furthermore, the openings of the perforated plate will preferably match those of the end plate in order to achieve a controlled change in the cross section of the openings in the end plate. In the present exemplary embodiment, the openings are round, openings on a circle around a center always having a constant diameter, but the openings on the different circular paths also have different diameters.
Die Lochplatte besitzt eine Drehachse, welche bevorzugt gleichzeitig die Längsachse des Anschlußstutzens ist. Ferner ist dieser Drehachse selbstverständich ein entsprechend manuell zu betätigender oder bevorzugt elektrischer Antrieb zugeordnet, mit dem die Lochplatte gedreht werden kann.The perforated plate has an axis of rotation, which is preferably also the longitudinal axis of the connecting piece. Furthermore, this axis of rotation is naturally associated with a correspondingly manually operated or preferably electric drive, with which the perforated plate can be rotated.
Durch die Drehung der Lochplatte im Verhältnis zur Abschlußplatte wird der Querschnitt der Öffnungen in der Abschlußplatte beeinflußt, so daß der Luft-Volumenstrom erhöht oder vermindert werden kann.The cross section of the openings in the end plate is influenced by the rotation of the perforated plate in relation to the end plate, so that the air volume flow can be increased or decreased.
Der Anschlußstutzen kann in einem Ausführungsbeispiel der Erfindung trichterförmig zur Abschlußplatte hin erweiternt ausgebildet sein. Ein derartig geformter Deckenauslaß ist besonders für niedrigere Räume einsetzbar, da hier die Luftströme mehr horizontal ausgebracht werden. In dem anderen Ausführungsbeispiel der Erfindung ist der Anschlußstutzen gleich dem Außendurchmesser des Auslasses, so daß auch die Luftstrome durch die Öffnungen der Abschlußplatte vertikal in den Raum austreten. Dieser Deckenauslaß ist besonders für höhere Räume geeignet, da die Luftströme tiefer in den Raum eindringen können.In one exemplary embodiment of the invention, the connecting piece can be designed in a funnel-shaped manner towards the end plate. A ceiling outlet shaped in this way can be used particularly for lower rooms, since the air streams are spread out more horizontally here. In the other embodiment According to the invention, the connecting piece is equal to the outer diameter of the outlet, so that the air streams also emerge vertically into the room through the openings in the end plate. This ceiling outlet is particularly suitable for higher rooms because the air currents can penetrate deeper into the room.
Besonders bemerkenswert ist auch, daß dieser Deckenauslaß architektonisch sehr gefällig ist und von den üblichen Auslaßformen abweicht. Er dürfte beispielsweise auch in denkmalgeschützten Altbauten einsetzbar sein.It is also particularly noteworthy that this ceiling outlet is architecturally pleasing and deviates from the usual outlet shapes. For example, it should also be usable in listed old buildings.
Durch die Drehung der Lochplatte im Verhältnis zur Abschlußplatte wird der Querschnitt der Öffnungen in der Abschlußplatte beeinflußt, so daß der Luft-Volumenstrom erhöht oder vermindert werden kann.The cross section of the openings in the end plate is influenced by the rotation of the perforated plate in relation to the end plate, so that the air volume flow can be increased or decreased.

Gemäß Fig. 1 besteht ein Deckenauslaß R aus einem Anschlußstutzen 1 bzw. 1a. Hierbei sind in Fig. 1 zwei konstruktive Möglichkeiten angedeutet. Der gestrichelt dargestellte runde Anschlußstutzen 1a soll insbesondere in hohen Räumen eingesetzt werden, da bei ihm die eingeführte Luft im wesentlichen vertikal ausgeblasen wird, wie dies durch die gestrichelt dargestellten Pfeile 2a angedeutet ist.1, a ceiling outlet R consists of a connecting
Der Anschlußstutzen 1 erweitert sich dagegen trichterförmig und wird deshalb vorwiegend in niedrigeren Räumen eingesetzt, in denen die Luft mehr horizontal ausgeblasen wird, was wiederum durch die entsprechenden Pfeile 2 angedeutet ist.The connecting piece 1, on the other hand, widens in a funnel shape and is therefore mainly used in lower rooms in which the air is blown out more horizontally, which in turn is indicated by the corresponding arrows 2.
Der Anschlußstutzen 1 schließt nicht näher gezeigt an eine entsprechende Luftleitung an. Zum Raum hin wird er von einer Abschlußplatte 3 begrenzt, welche von Löchern 4 durchsetzt ist. Diese Löcher 4 haben im gezeigten Ausführungsbeispiel unterschiedliche Durchmesser.The connecting piece 1 connects not shown to a corresponding air line. To the room it is delimited by an
Im Inneren des Anschlußstutzens 1 befindet sich eine weitere Lochplatte 5, welche lagebezogen der Abschlußplatte 3 zugeordnet ist. Diese Lochplatte 5 ist drehbar und zwar im vorliegenden Ausführungsbeispiel um die strickpunktiert angedeutete Drehachse 6. Entsprechende Antriebselemente für die Drehung der Lochplatte 5 sind nicht gezeigt.In the interior of the connecting piece 1 there is a further

Gemäß Fig. 2 liegen die Lochplatte 5 und die Abschlußplatte 3 so übereinander, daß die Öffnungen 4 der Abschlußplatte 3 mit Öffnungen 7 der Lochplatte 5 übereinstimmen. Damit wird der größtmögliche freie Querschnitt der Öffnungen 4 der Abschlußplatte 3 erreicht. In diesem Fall werden auch vertikal die größtmöglichen Eindringtiefen und horizontal die größten Wurfweiten möglich.2, the
Wird nun die Lochplatte 5 verdreht, so zeigen sich die beispielsweise in den Figuren 3 und 4 dargestellten Konfigurationen. Folgendes wird erreicht:
Bei Drehung der Lochplatte 5 verkleinert sich der freie Querschnitt der Öffnungen 4 in der Abschlußplatte 3. Damit erhöht sich auch der Druckverlust und der Volumenstrom verringert sich. Dies kann beispielsweise bei einer Abgleichung eines Zuluftstranges notwendig sein oder wenn ein einzelner Auslaß gedrosselt werden muß. Letzteres wird bei Zugerscheinungen notwendig.If the
When the
Erfindungsgemäß kann vor den Deckenauslaß R ferner ein Konstant-Volumenstromregler 8 eingesetzt werden. Dieser soll unabhängig vom Widerstand immer einen gleichbleibenden Volumenstrom an Luft durchlassen. Damit wird folgendes erreicht:
Durch Verdrehen der Lochplatte 5 wird der Turbulenzgrad erhöht, so daß sich die Eindringtiefen bzw. Wurfweiten gegenüber der in Fig. 2 gezeigten Ausgangsstellung wesentlich verkürzen. Dies bedeutet, daß bei gleichbleibendem Volumenstrom die Eindringtiefe an den Raum angepaßt werden kann und zwar ohne großen Aufwand.According to the invention, a constant volume flow controller 8 can also be used in front of the ceiling outlet R. This should always allow a constant volume flow of air to pass through regardless of the resistance. This achieves the following:
By turning the
Unabhängig von diesen technischen Vorteilen bleibt bei allen Stellungen des erfindungsgemäßen Deckenauslasses R das Aussehen des Auslasses architektonisch ansprechbar und ist daher beispielsweise auch in denkmalgeschützten Altbauten einsetzbar.Regardless of these technical advantages, the appearance of the outlet remains architecturally responsive in all positions of the ceiling outlet R according to the invention and can therefore also be used, for example, in heritage-protected old buildings.
