Within a row, the air outlet openings in the preferred embodiment of the invention have a distance of about 4 mm, resulting in the case of a standard laboratory based on the area air exchange rate in the range between 12.5 - 37.5 m 3 / m 2 / h , which corresponds approximately to 4 to 12 times the air exchange rate in a standard laboratory.
Die Erfindung zeichnet sich dadurch aus, dass wenigstens einer der Arbeitstische, bevorzugt jedoch alle Arbeitstische, im Bereich ihrer Rückseite eine schlitzartige Öffnung aufweisen, durch die hindurch Warmluft aus dem Bereich unter der Tischplatte, die z.B. durch elektrische Geräte wie Arbeitsplatzrechner, Kühlschränke, Steckdosenleisten etc. sowie auch die Körperwärme von an den Tischen arbeitenden Personen erzeugt wird, nach oben hin aus diesem Bereich abströmen kann. Die schlitzartige Öffnung kann entweder in der Tischplatte des Arbeitstisches geformt sein, oder kann rückseits des hinteren Randes der Tischplatte durch eine Ausnehmung gebildet werden, die sich bevorzugt zwischen den beiden hinteren vertikalen Pfosten oder Tischbeinen des Tisches erstreckt, wenn dieser in bekannter Weise einen tragenden Rahmen, bevorzugt aus Metall, besitzt.The invention is characterized in that at least one of the worktables, but preferably all worktables, have a slot-like opening in the region of their rear side, through which hot air from the area below the table top, which is e.g. generated by electrical equipment such as workstations, refrigerators, power strips, etc., as well as the body heat of persons working on the tables, can flow out of this area at the top. The slot-like opening may either be formed in the table top of the worktable, or may be formed on the back of the rear edge of the table top by a recess which preferably extends between the two rear vertical uprights or legs of the table, if this in a known manner a supporting frame , preferably of metal, has.
Bei der bevorzugten Ausführungsform der Erfindung sind im Bereich der Rückseite der Arbeitstische vertikale Leitplatten angeordnet, die sich bevorzugt sowohl im Bereich unterhalb, als auch im Bereich oberhalb der Tischplatten in vertikaler Richtung erstrecken, und die als Führungsflächen dienen, an denen die erwärmte Luft aufsteigt. Durch den sich dabei einstellenden Coanda-Effekt wird die aufsteigende Warmluft aus dem Bereich unterhalb der Tischplatte in Richtung zur Führungsfläche hin bewegt und während des Aufströmens zu dieser hin gedrängt, was in vorteilhafter Weise dazu führt, dass durch die Führungsfläche eine Kanalisierung der aufsteigenden Luft entsteht, wodurch diese sich nicht mehr so stark mit der von oben her nachströmenden kühlen Frischluft vermischt. Hierdurch wir der Energiebedarf der erfindungsgemäßen Anordnung noch weiter verringert.In the preferred embodiment of the invention, vertical guide plates are arranged in the region of the back of the work tables, which preferably extend in the vertical direction in the region below as well as in the region above the tabletops. and serve as guide surfaces on which the heated air rises. As a result of the resulting Coanda effect, the rising warm air is moved out of the area below the table top in the direction of the guide surface and forced towards it during the upward flow, which advantageously leads to channeling of the ascending air through the guide surface , whereby they no longer mixed so much with the fresh air flowing in from above. This further reduces the energy requirement of the arrangement according to the invention.
Bei der bevorzugten Ausführungsform der Erfindung ist eine erste Leitplatte unterhalb der Tischplatte angeordnet ist, und/oder eine zweite Leitplatte erstreckt von der schlitzartigen Öffnung aus nach oben hin in Richtung zur Decke des Raums.In the preferred embodiment of the invention, a first guide plate is disposed below the table top, and / or a second guide plate extends upward from the slot-like opening toward the ceiling of the room.
Um bei rückseitig aneinander gestellten Tischen die Vorteile der erfindungsgemäßen Anordnung in vollem Umfang nutzen zu können, ist die zweite Leitplatte vorzugsweise aus einem insbesondere für Laserlicht undurchsichtigen Werkstoff und/oder einem feuerhemmenden Werkstoff oder einem Werkstoff mit hoher mechanischer Festigkeit, insbesondere einem explosionsresistenten Werkstoff, geformt. Hierdurch erfüllt die Leitplatte in vorteilhafter Weise gleichzeitig auch noch die Funktion eines Schutzes gegen Laserstrahlung, einer Brandschutzbarriere und/oder eines Splitterschutzes.In order to be able to fully utilize the advantages of the arrangement according to the invention in the case of tables placed on the back side, the second guide plate is preferably formed of a material that is opaque in particular for laser light and / or a fire-retardant material or a material with high mechanical strength, in particular an explosion-resistant material , As a result, the guide plate advantageously also simultaneously fulfills the function of protection against laser radiation, a fire barrier and / or splinter protection.
Alternativ kann die zweite Leitplatte auch aus einem durchsichtigen Werkstoff, bevorzugt aus Glas oder Plexiglas, bestehen, um trotz einer räumlichen Trennung zweier rückseitig einander gegenüberliegender Arbeitsplätze die strömungsmäßigen Vorteile zu erhalten und gleichzeitig eine Durschicht zu ermöglichen.Alternatively, the second baffle also made of a transparent material, preferably made of glass or Plexiglas, in order to maintain the flow advantages despite a spatial separation of two back-facing jobs and at the same time to allow a Durschicht.
Der wenigstens eine Arbeitstisch weist vorzugweise einen Rahmen auf, der zwei rückseitige Rahmenpfosten besitzt, zwischen denen sich die schlitzartige Öffnung erstreckt. Die beiden rückseitigen Pfosten sind dabei bevorzugt als Metall oder Kunststoffprofile ausgebildet, die in vertikaler Richtung über aufgesetzte weitere Pfosten verlängerbar sind. In den aufgesetzten weiteren Pfosten, die vorzugsweise über Verbindungselemente fest mit den unteren Rahmenpfosten verbindbar sind, können bevorzugt Aufnahmenuten zur Aufnahme von weiteren vertikalen Leitplatten und/oder von horizontalen Regalböden oder Energiekanälen, bzw. horizontalen Trägern, auf denen die horizontalen Regalböden bzw. Energiekanäle aufliegen, vorgesehen sein. Die Regalböden erstrecken sich dabei ebenfalls lediglich bis an die vertikale Ebene des gangseitigen Längsrandes der schlitzförmigen Öffnung heran, so dass die aus der Öffnung in der Tischplatte, bzw. im Arbeitstisch aufsteigende Warmluft in dem entstehenden Freiraum hinter den Regalböden ebenfalls ungehindert bis in den Deckenbereich aufströmen kann.The at least one worktable preferably comprises a frame having two rear frame posts between which the slot-like opening extends. The two back posts are preferably formed as metal or plastic profiles, which can be extended in the vertical direction over patch further posts. In the attached additional posts, preferably with fasteners The lower frame post can be connected, preferably receiving grooves for receiving further vertical guide plates and / or horizontal shelves or energy channels, or horizontal beams on which the horizontal shelves or energy channels rest, may be provided. The shelves also extend only to the vertical plane of the gangway longitudinal edge of the slot-shaped opening zoom, so that the rising from the opening in the table top, or in the working table warm air in the resulting space behind the shelves also flow unhindered into the ceiling area can.
Gemäß einer weiteren Ausführungsform der Erfindung weist wenigstens einer der Längsränder der schlitzförmigen Öffnung, insbesondere der auf der Seite des Gangbereichs liegende gangseitige Längsrand, zur Unterstützung der Strömungsbewegung der aus dem Bereich unter der Tischplatte aufsteigenden Luft eine bogenförmig abgerundete Querschnittsform, bevorzugt eine trompetenförmige oder venturiförmige Querschnittsform, auf. Hierdurch wird erreicht, dass die aufsteigende Warmluft auf einen noch engeren Bereich konzentriert wird, was einer Durchmischung mit der zugeführten Kaltluft zusätzlich entgegen wirkt.According to a further embodiment of the invention, at least one of the longitudinal edges of the slot-shaped opening, in particular the gangway-side longitudinal edge, has an arcuately rounded cross-sectional shape, preferably a trumpet-shaped or venturi-shaped cross-sectional shape, to support the flow movement of the air rising from below the table top , on. This ensures that the rising hot air is concentrated to an even narrower range, which additionally counteracts a mixing with the supplied cold air.
Schließlich betrifft die Erfindung die vorteilhafte Verwendung wenigstens eines Arbeitstischs mit einem Rahmen und einer Tischplatte, der im Bereich seiner Rückseite eine schlitzartige Öffnung aufweist, durch die hindurch Warmluft aus dem Bereich unterhalb der Tischplatte nach oben abströmen kann, in einer zuvor beschriebenen Anordnung zur Belüftung eines Laborraums. Obgleich die Erfindung zuvor und nachfolgend ausschließlich am Beispiel eines Laborraums beschrieben wurde, ist die erfindungsgemäße Anordnung gleichermaßen auch zur Belüftung von Büroräumem einsetzbar, die vom Schutz her mit eingeschlossen sein sollen.Finally, the invention relates to the advantageous use of at least one work table with a frame and a table top, which has a slot-like opening in the region of its back through which warm air from the area below the table top can flow upwards in a previously described arrangement for ventilation of a laboratory space.
