Abstract

Es wird ein Doppelboden (3) zur Luftabsaugung aus Räumen, ins­ besondere Reinräumen, beschrieben, die mit dem Zuluftsystem (2) einer Lüftungs- und/oder Klimaanlage in Verbindung stehen. Beim Doppelboden (3) ist die obere Bodenebene (7) von auf Stützglie­ dern (6) ruhenden Loch- und/oder Schlitzplatten (7) gebildet, die an ihrer Unterseite ein von Versteifungsstegen, -profilen (9,10) oder dergleichen gebildetes Versteifungssystem aufweisen. There is a double floor (3) for air extraction from rooms, ins special clean rooms, which are described with the supply air system (2) ventilation and / or air conditioning. In the double floor (3), the upper floor level (7) is from to the support structure dern (6) resting perforated and / or slotted plates (7) formed on their bottom one of stiffening webs, profiles (9,10) or Have the same stiffening system formed.

Um bei geringen Druckverlusten eine gleichmäßige Verteilung der abgesaugten Luft über die gesamte Querschnittsfläche des Raumes zu erreichen, sind den von der Loch- und/oder Schlitzplatte (7) abgewendeten Bereichen des Versteifungssystems (9,10) Abdeckungen zugeordnet, welche mindestens im Bereich der Versteifungssteg- oder -profilkanten (9,10) über die untere Ebene des Versteifungssystems vorspringende Düsenöffnungen (16) begren­ zen oder ausbilden. Dabei sind sämtliche Düsenöffnungen (11,16) mit übereinstimmender Öffnungsrichtung vorgesehen. To ensure even distribution with low pressure drops of the extracted air over the entire cross-sectional area of the To reach the room are those of the perforated and / or Slotted plate (7) facing away from areas of the stiffening system (9, 10) Associated covers, which at least in the area of Stiffening web or profile edges (9,10) over the lower level of the stiffening system limit projecting nozzle openings (16) Zen or train. All nozzle openings (11, 16) are included matching opening direction provided.
