Description

Die Erfindung betrifft einen Luftauslaß zur Erzeugung einer turbulenzarmen Verdrängungsströmung in Bodennähe eines zu belüftenden Raumes. Die Vorrichtung besteht im wesentlichen aus einem quaderförmigen Gehäuse mit einem Anschlußstutzen und einer dem zu belüftenden Raum zugewandten Seitenwand, die mit Perforationen versehen ist.The invention relates to an air outlet for generating a low-turbulence displacement flow near the floor of a room to be ventilated. The device consists essentially of a cuboid housing with a connecting piece and a side wall facing the space to be ventilated, which is provided with perforations.

Derartige Luftauslässe sind allgemein bekannt und dienen zur Erzeugung einer sogenannten Quellüftung, wobei es sich um ein Luftführungssystem mit turbulenzarmer Verdrängungsströmung handelt. Die Zuluft wird mit einem niedrigen Impuls in Bodennähe dem zu belüftenden Raum zugeführt und soll mit geringer Strömungsgeschwindigkeit tief in den Raum eindringen. Durch den aus Wärmequellen, wie Maschinen und Personen, resultierenden thermischen Auftrieb bilden sich im Raum, vom Boden ausgehend, bis zur Decke aufsteigende Quellströmungen.Such air outlets are generally known and are used to produce a so-called source ventilation, which is an air duct system with a low-turbulence displacement flow. The supply air is supplied to the room to be ventilated with a low impulse close to the floor and should penetrate deep into the room at a low flow rate. Due to the thermal buoyancy resulting from heat sources such as machines and people, swelling currents rising from the floor to the ceiling are formed in the room.

Bei dem vorbeschriebenen Luftführungssystem wird die gegenüber der Raumluft kältere Zuluft direkt im Aufenthaltsbereich dem Raum zugeführt, so daß die von Maschinen und Personen abgegebene Wärme und damit auch in der Raumluft befindlicher Schadstoff durch die Quellströmung zur Raumdecke hin transportiert und dort abgesaugt werden kann.In the air duct system described above, the supply air, which is colder than the room air, is fed directly into the room in the lounge area, so that the heat emitted by machines and people and thus also the pollutant in the room air can be transported to the ceiling of the room by the source flow and extracted there.

Ein wesentlicher Nachteil der bekannten Luftauslässe zur Erzeugung einer Quellüftung besteht darin, daß in Auslaßnähe durch erhöhte Luftgeschwindigkeiten und niedrige Lufttemperaturen Zugerscheinungen auftreten können. Die Größe des davon betroffenen Nahbereichs ist insbesondere abhängig vom Zuluftvolumenstrom und der Temperaturdifferenz zwischen der Zuluft und der Raumluft.A major disadvantage of the known air outlets for generating a source ventilation is that drafts can occur in the vicinity of the outlet due to increased air speeds and low air temperatures. The size of the close range affected by this depends in particular on the supply air volume flow and the temperature difference between the supply air and the indoor air.

Der Erfindung liegt die Aufgabe zugrunde, einen Luftauslaß der eingangs beschriebenen Art so auszubilden, daß sich bei einer optimalen Zuluftverteilung im Raum der von Zugerscheinungen betroffene Auslaßbereich auf ein Minimum reduzieren läßt, ohne-dazu den Zuluftvolumenstrom einschränken zu müssen.The invention has for its object to provide an air outlet of the type described in such a way that, with an optimal supply air distribution in the room, the outlet area affected by drafts can be reduced to a minimum without having to restrict the supply air volume flow.

Zur Lösung dieser Aufgabe wird von einem Luftauslaß der im Oberbegriff des Anspruchs 1 genannten Art ausgegangen, welcher erfindungsgemäß die in seinem kennzeichnenden Teil angegegebenen Merkmale aufweist.To solve this problem, an air outlet of the type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features specified in its characterizing part.

Durch die in Strömungsrichtung der perforierten Seitenwand erfindungsgemäß vorgelagerten schwenkbaren Lamellen läßt sich die Zuluftströmung in einem Winkel von beispielsweise 20° zur Horizontalen schräg nach oben gerichtet in den zu belüftenden Raum einbringen. Dadurch wird in Auslaßnähe ein schneller Kaltluftabfall, der zu unerwünscht hohen Luftgeschwindigkeiten führt, verhindert. Zudem bewirken die erfindungsgemäß zwischen den Enden der Lamellen und der perforierten Seitenwand in Strömungsrichtung divergierend angeordneten Leitbleche eine radiale Auffächerung der Zuluftstrahlen, die je nach Schrägstellung der Leitbleche bis zu einer annähernd halbkreisförmigen Luftverteilung ausgeweitet werden kann.Due to the swiveling lamellae arranged upstream in the direction of flow of the perforated side wall, the supply air flow can be introduced at an angle of, for example, 20 ° to the horizontal and directed upwards into the room to be ventilated. This prevents a rapid drop in cold air in the vicinity of the outlet, which leads to undesirably high air velocities. In addition, the baffles arranged diverging in the flow direction between the ends of the lamellae and the perforated side wall cause a radial fanning out of the supply air jets, which, depending on the inclination of the baffle plates, can be expanded to an approximately semicircular air distribution.

Nach einer Ausgestaltung der Erfindung sind im Ausströmraum zwischen der mit Perforationen versehenen Seitenwand und den Leitblechen vertikal ausgerichtete Lochblechstreifen angeordnet, die zu beiden Seitenbereichen des Ausströmraumes im Grundriß dreieckförmige Raumabschnitte begrenzen.According to one embodiment of the invention, vertically aligned perforated metal strips are arranged in the outflow space between the perforated side wall and the baffles, which delimit triangular spatial sections on both side areas of the outflow space.

Durch die vorzugsweise de- und remontierbaren Lochblechstreifen kann je nach Bedarf auf die Auffächerung der Zuluftstrahlen verzichtet werden, so daß diese im wesentlichen geradlinig in den zu belüftenden Raum gelangen. Die Auffächerung der Zuluftstrahlen kann aber auch auf der einen oder anderen Seite des Luftauslasses eingeengt werden, indem ein Lochblechstreifen nur auf der jeweiligen Seite zum Einsatz kommt.Due to the perforated metal strips, which can preferably be dismantled and reassembled, there is no need for the supply air jets to be fanned out, so that they enter the space to be ventilated in a substantially straight line. The fanning out of the supply air jets can also be restricted on one side or the other of the air outlet by using a perforated metal strip only on the respective side.

Vorzugsweise sind die Lamellen und die Leitbleche aus einem Teil gefertigt und jeweils über dünne, plastisch verformbare Stege miteinander verbunden. Dadurch lassen sich die Herstellungskosten für den Luftverteilugsmechanismus insgesamt gegenüber einem ausschließlich aus Einzelteilen zusammengesetzten Luftverteilungsmechanismus erheblich reduzieren. Lamellen und Leitbleche können z.B. in einfacher Weise mit Hilfe eines Stanzwerkzeuges aus einer entsprechend dimensionierten Blechplatte ausgestanzt und sodann durch Biegen in die gewünschte Endform gebracht werden.The lamellae and the guide plates are preferably made from one part and are connected to one another in each case via thin, plastically deformable webs. As a result, the manufacturing costs for the air distribution mechanism as a whole can be considerably reduced compared to an air distribution mechanism composed exclusively of individual parts. Slats and baffles can e.g. stamped out of a correspondingly dimensioned sheet metal plate in a simple manner with the aid of a punching tool and then brought into the desired final shape by bending.

Die Perforationen in der Seitenwand bestehen vorzugsweise aus kreisrunden Löchern mit einem Durchmesser von etwa 3 mm, wobei die Löcher in gleichmäßiger Verteilung über die Fläche der Seitenwand in solchen Abständen voneinander angeordnet sind, daß ein freier Querschnitt etwa von 30 bis 35 % der Fläche der Seitenwand entsteht.The perforations in the side wall preferably consist of circular holes with a diameter of about 3 mm, the holes being arranged in a uniform distribution over the surface of the side wall at such intervals that a free cross section of about 30 to 35% of the area of the side wall arises.

Der Luftauslaß besteht aus einem quaderförmigen Gehäuse 1, das auf dem Boden eines zu belüftenden Raumes aufgestellt oder an einer Raumwand oder in diese integriert angeordnet sein kann.The air outlet consists of a cuboid housing 1, which can be placed on the floor of a room to be ventilated or can be arranged on a wall of the room or integrated therein.

An der Oberseite des Gehäuses 1 ist ein im Querschnitt rechteckförmiger Anschlußstutzen 2 vorgesehen, der mit einer nicht dargestellten Zuluftleitung verbindbar ist.At the top of the housing 1, a connecting piece 2 with a rectangular cross section is provided, which can be connected to a supply air line, not shown.

Die dem Raum zugewandte Vorderseite des Gehäuses 1 ist durch eine abnehmbare oder schwenkbare oder verschiebbare Seitenwand 3 gebildet, welche in gleichmäßiger Verteilung über ihre Fläche mit Perforationen 4 versehen ist.The front of the housing 1 facing the room is formed by a removable or pivotable or displaceable side wall 3, which is provided with perforations 4 in a uniform distribution over its surface.

Der Innenraum des Gehäuses 1 ist in einen Einströmraum 5 und einen Ausströmraum 6 unterteilt. Die Unterteilung erfolgt durch Lamellen 7 und Leitbleche 8. Die Lamellen 7 sind in Abständen vertikal übereinander angeordnet und um horizontale Längsachsen schwenkbar. Die Leitbleche 8 sind an den Enden der Lamellen 7 angeschlossen und von dort aus so divergierend ausgerichtet, daß ihre den Lamellen 7 abgewandten Längskanten bis zu Seitenkanten der Seitenwand 3 reichen. Dadurch entsteht eine kontinuierliche Aufweitung des Ausströmraumes 6 in Strömungsrichtung.The interior of the housing 1 is divided into an inflow space 5 and an outflow space 6. The subdivision is made by fins 7 and baffles 8. The fins 7 are arranged vertically one above the other at intervals and can be pivoted about horizontal longitudinal axes. The baffles 8 are connected to the ends of the lamellae 7 and from there aligned so divergingly that their longitudinal edges facing away from the lamellae 7 extend to the side edges of the side wall 3. This creates a continuous widening of the outflow space 6 in the direction of flow.

In Fig. 3 sind zu beiden Seiten des Luftauslasses zwischen der Seitenwand 3 und den Leitblechen 8 Lochblechstreifen 9 angeordnet, die in Fig. 4 fehlen. Durch die Lochblechstreifen 9 läßt sich die in Fig. 4 veranschaulichte Auffächerung der Zuluftstrahlen bis zu einer nahezu geradlinigen Ausrichtung der Zuluftstrahlen gemäß der Darstellung in Fig. 3 reduzieren.In Fig. 3 8 perforated plate strips 9 are arranged on both sides of the air outlet between the side wall 3 and the guide plates, which are missing in Fig. 4. Through the perforated sheet strips 9, the fanning out of the supply air jets illustrated in FIG. 4 can be reduced to an almost straight alignment of the supply air jets as shown in FIG. 3.

Fig. 5 verdeutlicht die in Auslaßnähe aufwärtsgerichtete Strömung der kalten Zuluft, welche erst in einem Abstand vom Auslaß dem Kaltluftphänomen zu sinken unterliegt, dabei aber bereits erheblich an Geschwindigkeit verloren hat.Fig. 5 illustrates the upward flow of the cold supply air near the outlet, which is only subject to the cold air phenomenon at a distance from the outlet, but has already lost considerable speed.

Die Fig. 6 und 7 stellen eine radial aufgefächerte Zuluftströmung einer geradlinigen Zuluftströmung gegenüber.6 and 7 contrast a radially fanned supply air flow with a straight supply air flow.

Schließlich zeigt Fig. 8 die Möglichkeit, bei einer Reihe von Luftauslässen nur bei den jeweils ersten und letzten im Außenseitenbereich auf den Einsatz von Lochblechstreifen zu verzichten, so daß eine Auffächerung der Zuluftstrahlen nur am Anfang und Ende der Auslaßreihe erfolgt und die Luftauslässe im übrigen die Strahlen geradlinig austreten lassen.Finally, Fig. 8 shows the possibility of dispensing with the use of perforated metal strips in the case of a row of air outlets only for the first and last ones in the outside area, so that the supply air jets are fanned out only at the beginning and end of the row of outlets and the air outlets otherwise Let the rays emerge in a straight line.
