Description
Einrichtung zur Abschirmung von Gebäuderäumen mittels Luftschleiers gegen Kaltlufteinbruch Es ist bekannt, Räume oder haumteile von der Umgebung durch bewegte, in sich geschlossene Luftschichten abzutrennen, welche gegen sie gerichtete Warm- oder .Kaltluftströmungen am Durchbrechen hindern, indem sie dieselben aus der Durchbruchsrichtung ablenken. Ein einfacher; ebener Luftschleier ist aber nicht imstande, das Einbrechen von Kaltluft namentlich beigrößeren Temperaturunterschieden und bei plötzlicher Öffnung von Türen und Fenstern zu verhindern, weil der Sperrluftschleier unter dem Druck der Kaltluft allmählich abgelenkt wird und damit Kaltluft an der der Druckluftdüsenseite entgegengesetzten Seite eindringt. Dies wird auch nicht dadurch verhindert, daß an der gegenüberliegenden Seite Saugdüsen oder Schlitze angeordnet sind, um die Luftströmung aufrechtzuerhalten.Device for shielding building rooms by means of air curtains Against cold air ingress It is known to keep rooms or parts of the environment through to separate moving, self-contained layers of air directed against them Prevent hot or cold air currents from breaking through by exiting them deflect the direction of the breakthrough. A simple one; but is not a level air curtain able to break in cold air, especially in the case of larger temperature differences and to prevent sudden opening of doors and windows because of the sealing air curtain is gradually diverted under the pressure of the cold air and thus cold air at the the opposite side of the compressed air nozzle. Nor will this this prevents suction nozzles or slots on the opposite side are arranged to maintain air flow.
Gemäß der Erfindung werden diese fJbelstände dadurch beseitigt, daß an beiden Seiten der Tür Düsenkästen mit schräg auswärts nach der Türachse gerichteten Düsen angeordnet sind, so daß zwei von den entgegengesetzten Seiten der abzusperrenden Öffnung ausgehende Sperrluftwände schräg auswärts gegeneinander gerichtet sind, die in einer gewissen Entfernung von der Öffnung gegeneinanderstoßen und sich gegenseitig in eine der Einbruchsrichtung der Kaltluft entgegengesetztenRichtung ablenken. Die einbrechende Kaltluft findet infolgedessen keine Einbruchsmöglichkeit an einer Stelle geringsten Widerstandes, sondern wird in zuverlässiger Weise von den Luftschleiern aufgefangen und abgelenkt, bis sie schließlich in der Mitte der Öffnung mit der strömenden Preßluft zusammen, entgegengesetzt der Einbruchsöffnung, zurückgetrieben wird.According to the invention, these deficiencies are eliminated in that on both sides of the door nozzle boxes with diagonally outward directed towards the door axis Nozzles are arranged so that two from opposite sides of the to be shut off Opening outgoing air barrier walls are directed diagonally outwards towards each other, which meet at a certain distance from the opening and each other deflect in a direction opposite to the ingress of cold air. the As a result, ingress of cold air does not find any possibility of ingress at one point of least resistance, but is relied on by the air veils caught and distracted until they finally find themselves in the center of the opening with the flowing compressed air together, opposite to the penetration opening, driven back will.
Die Zeichnung veranschaulicht als Ausführungsbeispiel eine Einrichtung gemäß der Erfindung.The drawing illustrates a device as an exemplary embodiment according to the invention.
Abb. I ist eine Ansicht und Abb. 2 ein Grundriß.Fig. I is a view and Fig. 2 is a plan view.
Auf der Innenseite der Raumwand, in der sich die Tür I befindet, sind an den seitlichen Türpfosten iibereinander Schlitzdüsen :2 angebracht, die durch Leitungen 3 mit der `Druckseite eines Gebläses q. verbunden sind, dessen Saugrohr mit j .bezeichnet ist. Die von den Schlitzdüsen erzeugten Luftströmungen erstrecken sich bei geringer Stärke über die ganze Höhe der Öffnung und sind schräg vorwärts gerichtet, so daß sie an den seitlichen Begrenzungen der Tür vorbeigehen und sich draußen in der Türachse treffen. Dabei werden die Luftströmungen in eine zur eindringenden Kaltluft entgegengesetzte Richtung abgelenkt.On the inside of the wall of the room, in which the door I is located, are on the side door posts, one above the other, slot nozzles: 2 attached, which pass through Lines 3 with the `pressure side of a fan q. are connected, the suction pipe is marked with j. The air currents generated by the slot nozzles extend at low strength over the entire height of the opening and are obliquely forward directed so that they pass the side limits of the door and themselves meet outside in the door axis. In doing so, the air currents are in one to penetrate Cold air deflected in the opposite direction.
Die Kaltluft, die durch die offene Tür in den Raum einzudringen sucht, stößt hierbei gegen die einen Sperrvorhang bildenden Luftströmungen und wird von diesen in ihre eigene Strömungsrichtung abgelenkt und dadurch an dem Eintritt in den Raum verhindert.The cold air that tries to enter the room through the open door, hits against the air currents forming a barrier curtain and is of deflected this in its own direction of flow and thereby at the entrance to prevents the room.
Die Preßluftdüsen können eine beliebige geeignete Gestaltung undAnordnung besitzen, z. B. als eine Reihe von übereinander angeordneten Düsen vorgesehen sein. Sie können sowohl auf der Innenseite als auch auf der Außenseite der Raumwand angeordnet sein. Das Wesen der Erfindung besteht darin, daß durch die Düsenanordnung vor der Öffnung eine die Kaltluft ablenkende, wie ein Sperrvorhang wirkende, keilförmige Luftströmung erzeugt wird.The compressed air nozzles can be of any suitable design and arrangement own, e.g. B. be provided as a row of nozzles arranged one above the other. They can be arranged on the inside as well as on the outside of the room wall be. The essence of the invention is that by the nozzle arrangement before Opening a wedge-shaped which deflects the cold air and acts like a barrier curtain Air flow is generated.
