Abstract

Fresh air is supplied into an enclosed space by an air flow radially and substantially without turbulence horizontally over a floor by an air outlet, the outlet openings of which are substantially flush with the floor surface. The air outlet has a cylindrical air guide collar (1) and a concentric insert (7). The air guide collar (1) has a curved collar section (3) merging radially outwardly into a flange (4) which overlaps and bears against the edge of an opening (2) in the floor. The funnel-shaped insert (7) converges from the top to bottom and has an insert flange (8) that extends radially outwardly in the same plane as the collar flange (4). The insert flange (8) narrows an annular flow passage (9) between the air guide collar (1) and the insert (7). The exhaust aperture of the insert (7) can be closed to some extent by a transverse, horizontally arranged deflecting or baffle plate (12).

Description

Die Erfindung betrifft einen Bodenquellauslaß aus einem koaxial in eine kreisrunde Bodenöffnung einsetzbaren zylindrischen Stutzen. Die Oberseite des Stutzens ist mit einer scheibenförmigen, axiale Durchtrittsöffnungen aufweisenden Abdeckung und die Unterseite des Stutzens ist mit einem topfförmigen, radiale Durchtrittsöffnungen aufweisenden Bodenteil versehen.The invention relates to a bottom source outlet from a cylindrical connecting piece which can be inserted coaxially into a circular bottom opening. The top of the nozzle is provided with a disk-shaped cover having axial through openings and the underside of the nozzle is provided with a cup-shaped, bottom part having radial through openings.

Derartige Bodenquellauslässe sind allgemein bekannt und zielen darauf ab, Zuluft turbulenzarm mit geringem Impuls aus dem Boden vertikal austreten zu lassen. Infolge der Thermik im Raum, verursacht durch Personen, Beleuchtung, wärmeabgebende Geräte und Sonneneinstrahlung, steigt die zugeführte kalte Luft aus dem Bodenbereich zur Decke, wo sie abgesaugt wird. Bei Geschwindigkeiten der aufsteigenden Raumluftströmung unter 0,1 m/s ist diese zugfrei.Such floor source outlets are generally known and aim to allow supply air to exit the floor vertically with little turbulence and with little momentum. As a result of the thermals in the room, caused by people, lighting, heat-emitting devices and sunlight, the cold air supplied rises from the floor area to the ceiling, where it is extracted. This is draft-free at speeds of rising indoor air flow below 0.1 m / s.

Da sich jedoch mit derartigen Quellauslässen keine nennenswerte Eindringtiefe der Luftstrahlen in horizontaler Richtung in den Raum erzielen läßt, werden lineare Luftauslässe bevorzugt, die unmittelbar über den Boden vor Brüstungen oder vor Trennwänden aufgestellt werden. Die Zuluft wird bei diesen Luftauslässen mit Austrittsgeschwindigkeiten von ca. 0,20 m/s horizontal ausgeblasen. Der austretende Luftstrahl legt sich über den Boden, weitet sich dort aus und steigt allmählich nach oben. Die horizontale Eindringtiefe der Luftstrahlen ist aber auch bei diesen Linearauslässen maximal nur ca. 6 m. Für tiefere Räume reicht daher die Eindringtiefe nicht aus, um allerorts Zuluft zuzuführen.However, since no significant depth of penetration of the air jets in the horizontal direction into the room can be achieved with such source outlets, linear air outlets are preferred which are set up directly above the floor in front of parapets or in front of partition walls. The supply air is at these air outlets with outlet speeds of approx. 0.20 m / s blown out horizontally. The exiting jet of air lies on the ground, expands there and gradually rises. However, the horizontal penetration depth of the air jets is also only about 6 m at these linear outlets. For deeper rooms, the penetration depth is therefore not sufficient to supply fresh air everywhere.

Der Erfindung liegt die Aufgabe zugrunde, einen Bodenquellauslaß der eingangs beschriebenen Art so auszubilden, daß er sich wie die bekannten Radialauslässe dieser Art punktuell über den Boden verteilt anordnen läßt, dabei aber eine vergrößerte horizontale Eindringtiefe der austretenden Zuluftstrahlen gewährleistet und somit eine wesentlich geringere Anordnungsdichte der Luftauslässe gewählt werden kann, um den gesamten Raum dennoch gleichmäßig mit Zuluft zu versorgen.The invention has for its object to provide a floor source outlet of the type described in such a way that it can be arranged like the known radial outlets of this type distributed over the floor, but ensures an increased horizontal penetration depth of the emerging supply air jets and thus a much lower arrangement density of the Air outlets can be selected in order to supply the entire room evenly with supply air.

Zur Lösung dieser Aufgabe wird von einem Bodenquellauslaß der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.To solve this problem, a base source outlet of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in the characterizing part of the same.

Durch den sich radial nach außen bogenförmig erweiternden, am zylindrischen Teil des Stutzens anschließenden Kragen, der in einen auf dem Rand der Bodenöffnung aufliegenden Flansch übergeht, und durch den innerhalb des Stutzens angeordneten, sich von oben nach unten trichterförmig verengenden Einsatz, der mit dem Stutzen einen Ringraum definiert, der in der Ebene des am Kragen des Stutzens angeordneten Flansches durch einen am Einsatz angeordneten radial nach außen vorstehenden Flansch verengt ist, und durch die horizontale konzentrisch angeordnete Prallplatte strömt die Zuluft radial und turbulenzarm in einem großen Radius um die Mittelachse des Auslasses horizontal über den Boden aus. Erst aufgrund des thermischen Auftriebes im Raum steigt die Zuluft mit sehr geringen Luftgeschwindigkeiten nach oben.Due to the radially outward widening collar, which adjoins the cylindrical part of the socket, which merges into a flange resting on the edge of the bottom opening, and the inside of the socket arranged from above downwardly funnel-shaped insert, which defines an annular space with the nozzle, which is narrowed in the plane of the flange arranged on the collar of the nozzle by a flange arranged radially outwardly projecting on the insert, and through the horizontal concentrically arranged baffle plate, the supply air flows radially and Low turbulence in a large radius around the center axis of the outlet horizontally from the floor. Only due to the thermal buoyancy in the room does the supply air rise at very low air velocities.

Obschon der erfindungsgemäße Bodenquellauslaß bündig mit dem Bodenniveau abschließt, läßt sich eine Strahlausbreitung wie bei einem rechteckigen Linearauslaß erzielen, der das Bodenniveau in der Regel mit mindestens 100 mm überragt, um die Zuluft aus einer der seitlichen senkrechten Begrenzungsflächen des Auslasses horizontal auszublasen. Daher muß dieser Linearauslaß auch stets vor einer Wand oder Brüstung aufgestellt werden, um die anderweitige Benutzbarkeit der Bodenflächen im übrigen nicht zu beeinträchtigen.Although the floor source outlet according to the invention is flush with the floor level, a jet spread can be achieved as with a rectangular linear outlet, which generally exceeds the floor level by at least 100 mm in order to horizontally blow the supply air out of one of the lateral vertical boundary surfaces of the outlet. Therefore, this linear outlet must always be placed in front of a wall or parapet so as not to impair the other usability of the floor surfaces.

Nach einer Ausgestaltung der Erfindung ist der Einsatz im Stutzen durch sich über den Ringraum erstreckende radiale Stege gehalten, so daß zusätzliche Maßnahmen nicht erforderlich sind, um eine ausreichende Belastbarkeit des Bodens auch im Bereich des Quellauslasses sicherzustellen.According to one embodiment of the invention, the use in the nozzle is held by radial webs which extend over the annular space, so that additional measures are not necessary in order to ensure that the base is sufficiently resilient even in the area of the source outlet.

Nach einer weiteren Ausgestaltung der Erfindung kann der Auslaßquerschnitt des Einsatzes durch ein Lochblech und/oder ein Gitter abgedeckt sein. Da die Stau- und Umlenkfunktion im wesentlichen durch die Prallplatte bestimmt wird, dient das Lochblech oder Gitter im übrigen dazu, die Begehbarkeit des Bodenquellauslasses ohne Stolpergefahr zu gewährleisten.According to a further embodiment of the invention, the outlet cross section of the insert can be covered by a perforated plate and / or a grid. Since the congestion and deflection function is essentially determined by the baffle plate, the perforated plate or grille also serves to ensure that the floor source outlet can be walked on without the risk of stumbling.

Bei einer weiteren Ausgestaltung der Erfindung ist die Prallplatte auf und vorzugsweise unter einem mit einem Lochblech versehenen Zentralbereich des Auslaßquerschnitts angeordnet.In a further embodiment of the invention, the baffle plate is arranged on and preferably under a central area of the outlet cross section provided with a perforated plate.

Die Anordnung der Prallplatte unter dem Lochblech hat den Vorteil, daß sich die Prallplatte gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung in unterschiedlichen Abständen zur Ebene des Lochbleches höhenverstellbar halten läßt.The arrangement of the baffle plate under the perforated plate has the advantage that the baffle plate can be kept adjustable in height according to a particularly advantageous embodiment of the invention at different distances from the level of the perforated plate.

Durch die erfindungsgemäße Höhenverstellbarkeit der Prallplatte kann der Anteil des durch das Lochblech ausgeblasenen Volumenstromes variiert werden. Damit verändert sich sowohl die vertikale Eindringtiefe des Zuluftstrahls als auch die Geschwindigkeit der vorzugweise durch radiale Stege über den Ringquerschnitt zwischen dem Einsatz und dem Stutzen ausströmenden Luftstrahlen. Vor allem bei größeren Luftvolumenströmen bevorzugt man, einen größeren Teil des Gesamtvolumenstromes durch das Lochblech nach oben zu blasen, um die Luftgeschwindigkeit der sich über dem Boden ausbreitenden Luftstrahlen nicht zu hoch ansteigen zu lassen.The proportion of the volume flow blown out through the perforated plate can be varied by the height adjustment of the baffle plate according to the invention. This changes both the vertical penetration depth of the supply air jet and the speed of the air jets, which preferably flow out through radial webs over the ring cross section between the insert and the nozzle. Especially with larger air volume flows, it is preferred to have a larger part of the total volume flow up through the perforated plate to blow so that the air velocity of the air jets spreading above the ground does not rise too high.

Der erfindungsgemäße Bodenquellauslaß eignet sich besonders gut, ihn mit dem bekannten linearen Quellauslaß vor Brüstungen oder Zwischenwänden zu kombinieren. Der Raumbereich kann dann bis zu 6 m Tiefe von den Zuluftstrahlen aus dem Linearauslaß durchspült werden und der restliche Raumbereich über punktuell angeordnete erfindungsgemäße Bodenquellauslässe.The floor source outlet according to the invention is particularly well suited to be combined with the known linear source outlet in front of parapets or partition walls. The area of the room can then be flushed through to the depth of 6 m by the supply air jets from the linear outlet, and the rest of the area can be flushed through floor source outlets according to the invention.

Der Bodenquellauslaß besteht aus einem zylindrischen Stutzen 1, der koaxial in eine Bodenöffnung 2 vertikal einsetzbar ist. Ein sich am zylindrischen Stutzen 1 nach oben anschließender, sich radial nach außen bogenförmig erweiternder Kragen 3 geht in einen Flansch 4 über, der im eingebauten Zustand des Auslasses auf dem horizontalen Rand der Bodenöffnung 2 aufliegt. Die Oberseite des Flansches 4 kann auch mit der Bodenoberseite bündig abschließen.The bottom source outlet consists of a cylindrical connection piece 1, which can be inserted coaxially into a bottom opening 2 vertically. A collar 3, which adjoins the cylindrical connection piece 1 upward and widens radially outward in an arc shape, merges into a flange 4 which, when the outlet is installed, rests on the horizontal edge of the bottom opening 2. The top of the flange 4 can also be flush with the top of the floor.

An der Unterseite ist der Stutzen 1 mit einem topfförmigen Bodenteil 5 versehen, das radiale Durchtrittsöffnungen 6 aufweist, über welche die Zuluft in den Auslaß gelangt.On the underside, the connection piece 1 is provided with a cup-shaped base part 5, which has radial through openings 6, through which the supply air enters the outlet.

Konzentrisch zum Stutzen 1 ist ein sich von oben nach unten trichterförmig verengender Einsatz 7 angeordnet, der an seinem im Durchmesser größeren Ende mit einem radial nach außen vorstehenden Flansch 8 versehen ist, welcher mit dem Flansch 4 am bogenförmig erweiterten Kragen 3 des Stutzens 1 in der gleichen Ebene liegt. Die Innenseite des Stutzens 1 und die Außenseite des Einsatzes 7 begrenzen einen Ringraum 9, dessen freier Querschnitt durch den Flansch 8 eine ausgeprägte Kontraktion erfährt.Concentric to the nozzle 1, a funnel-shaped insert 7 is arranged from top to bottom, which is provided at its larger diameter end with a radially outwardly projecting flange 8, which with the flange 4 on the arc-shaped collar 3 of the nozzle 1 in the same level. The inside of the connector 1 and the outside of the insert 7 delimit an annular space 9, the free cross section of which is markedly contracted by the flange 8.

Durch radiale Stege 10, die in gleichmäßiger Verteilung über den Umfang des Ringraumes 9 angeordnet sind, erhält der Einsatz 7 eine stabile Befestigung innerhalb des Stutzens 1.Radial webs 10, which are arranged in a uniform distribution over the circumference of the annular space 9, give the insert 7 a stable attachment within the connection piece 1.

In der Ebene der Flansche 4 und 8 ist der Einsatz 7 mit einem Lochblech 11 versehen, dem eine Prallplatte 12 zugeordnet ist. In Fig. 1 und 2 überdeckt die Prallplatte 12 das Lochblech 11, wogegen in Fig. 3 und 4 die Prallplatte 12 unter dem Lochblech 11 angeordnet ist und über eine im Einsatz 7 befestigte koaxiale Spindel 13 höhenverstellbar gelagert ist. Wie die Fig. 3 und 4 zeigen, ergibt sich in Abhängigkeit von der jeweiligen Position der Prallplatte der durch Pfeile veranschaulichte unterschiedliche Strömungsweg der Zuluftstrahlen.In the plane of the flanges 4 and 8, the insert 7 is provided with a perforated plate 11, to which a baffle plate 12 is assigned. 1 and 2, the baffle plate 12 covers the perforated plate 11, whereas in FIGS. 3 and 4 the baffle plate 12 is arranged under the perforated plate 11 and is height-adjustable by means of a coaxial spindle 13 fastened in the insert 7. 3 and 4 show, depending on the respective position of the baffle plate, the different flow path of the supply air jets illustrated by arrows results.

Die lokal unterschiedlichen Strömungsgeschwindigkeiten der Zuluft ergeben sich aus der über der jeweiligen Auslaßdarstellung aufgezeichneten Kurve.The locally different flow velocities of the supply air result from the curve plotted above the respective outlet representation.
