Abstract

In a ceiling outlet for three-dimensional airflows into rooms for heating and/or cooling purposes, having a connecting pipe (1) to an appropriate air feed line, a cover plate (3) having apertures (4) is to be positioned in front of the connecting pipe (1) and a rotatable perforated plate (5) is assigned to this cover plate.

Description

Die Erfindung betrifft einen Deckenauslaß für Luft-Vo­lumenströme in Räumen zu Heiz- und/oder Kühlzwecken mit einem Anschlußstutzen an eine entsprechende Luftzu­leitung.The invention relates to a ceiling outlet for air volume flows in rooms for heating and / or cooling purposes with a connection piece to a corresponding air supply line.

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.

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 eine Abschlußplatte mit Öffnungen vorgesetzt ist, welcher eine drehbare Lochplatte zugeordnet ist.To solve this problem, the connection piece is preceded by an end plate with openings, which is assigned a rotatable perforated plate.

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.

Die Lochplatte kann beispielsweise der Abschlußplatte vorgesetzt sein, bevorzugt ist sie jedoch im Inneren 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 selbstverständlich 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 of course associated with a correspondingly manually operated or preferably electric drive with which the perforated plate can be rotated.

Der Anschlußstutzen kann in einem Ausführungsbeispiel der Erfindung trichterförmig sich zur Abschlußplatte hin erweiternd ausgebildet sein. Ein derart 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 Luftströme 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 shape to widen towards the end plate. A ceiling outlet shaped in this way can be used particularly for lower rooms, since the air flows are more horizontally distributed here. In the other exemplary embodiment of 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.

In einem weiteren Ausführungsbeispiel der Erfindung ist daran gedacht, dem Auslaß einen Konstant-Volumenstrom­regler vorzuschalten, der unabhängig vom Widerstand immer einen gleichbleibenden Luft-Volumenstrom durchläßt. Bei Veränderung des Querschnittes 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 an den Raum ohne großen konstruktiven Aufwand angepaßt werden kann.In a further embodiment of the invention, it is contemplated to connect a constant volume flow controller upstream of the outlet, which always allows a constant air volume flow to pass regardless of the resistance. When changing the cross section of the openings in the end plate, the degree of turbulence is then increased, so that the penetration depths or throwing distances can be shortened considerably as a result. This means that with a constant air volume flow, the penetration depth can be adapted to the room without great design effort.

Besonders bemerkenswert ist auch, daß dieser Deckenauslaß architektonisch sehr gefällig ist und von den üblichen Auslaßformen abweicht. Er dürfte bei­spielsweise auch ein 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 possible to use a listed old building.

Weitere Vorteile, Merkmale und Einzelheiten der Er­findung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in

  • Fig. 1 einen schematisch im Querschnitt dargestellten Deckenauslaß;
  • Fig. 2 eine Draufsicht auf den Deckenauslaß gemäß Fig. 1;
  • Fig. 3 eine Draufsicht auf den Deckenauslaß gemäß Fig. 1 in einer anderen Gebrauchslage;
  • Fig. 4 eine Draufsicht auf den Deckenauslaß gemäß Fig. 1 in einer weiteren Gebrauchslage.
Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
  • Figure 1 is a ceiling outlet shown schematically in cross section.
  • FIG. 2 shows a top view of the ceiling outlet according to FIG. 1;
  • 3 shows a top view of the ceiling outlet according to FIG. 1 in a different position of use;
  • Fig. 4 is a plan view of the ceiling outlet of FIG. 1 in a further position of use.

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 piece 1 or 1a. Here, two design options are indicated in Fig. 1. The round connecting piece 1 a shown in broken 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 broken lines.

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 end plate 3 which is penetrated by holes 4. In the exemplary embodiment shown, these holes 4 have different diameters.

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 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.

Durch diese Lochplatte 5 kann in einfacher Weise in das Strahlverhalten des Deckenauslasses R eingegriffen werden. Ferner dient sie auch zur Drosselung des Volumenstromes.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.

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 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.

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 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.

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 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.

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.
