Definitions

  • the invention concerns a ventilation system to ventilate spaces with natural draught.
  • the ventilation system is used on roofs or in walls of industrial buildings.
  • the ventilation system is equipped to ventilate spaces while precipitation is caught in extrusions with gutters and where the in-between distance of the louvres and flaps prohibit the weather entries to pass along the gutters and enter the ventilated spaces.
  • the ventilation system provides the possibillity to open the flaps completely to obtain a maximum passage when necessary in case of a fire to expel large quantities of smoke and combustion fumes.
  • Ventilation systems which are equipped with adjustable flaps are well known.
  • the European patent application EP-A-0103861 describes a system with fixed louvres, placed at about 45 degrees in reference to the airstream and is equipped with adjustable louvres which can rotate about 90 degrees.
  • the passage of this type of constructions is restricted by the requirement to keep out precipitation to such an extent that the ventilation capacity is hardly sufficient in case of fire.
  • the invention provides a system as defined in the single claim
  • a universal ventilation system requires an air passage with a C v -value of 0 to 0.6.
  • the required C v of the air passage should have a value of 0.5 to 0.9.
  • the values of air passage can be measured following the standard method described in the norm DIN 18232, part 3 chapter 3.7.
  • a ventilation opening (3) where a frame (4) is placed.
  • a frame (4) On this frame (4) is a casing (5).
  • louvres (6) are fastened. These louvres (6) are being composed from parts which fit together and are connected with fastening measurements.
  • the lower part is an extruded profile (7).
  • This profile (7) is partly in the form of a gutter (8) and a catcher of water drops (9), at (10) is a provision to connect extruded profile (7) to strip (11) made from sheet.
  • a second extruded profile (12) is fastened with provisions (13).
  • the extruded profile (12) contains a gutter (14) with dripping edge (15), a flat part (16) with provisions (17) to mount. From provision (13) goes a flat part (18) which is connected to a cylindrical (possibly hollow) part (19). Bearing parts (20) fit around the cylindrical part (19) which makes it possible to rotate flap (21) on the cylindrical part (19).
  • the flap (21) is composed of an extruded profile (22) and strips (23) and (24) where (24) is meant as reinforcement.
  • the extruded profile (22) contains providings for connections (25) for strip (23) and a curved part (26) that fits and rotates around bearing part (20). The curved part (26) grasps the bearing part (20) for more than 180 degrees. Rims (27) serve to hold a strip with a mohair seal.
  • the bearing part (20) is cylindric and fits around the cylindrical part (19) and in the curved part (26) of profile (22). A part of the wall of the cylinder is taken away and leads through the flat part (18) of profile (12). Along the whole length of the hinge a number of bearing parts (20) are placed at even distances. If necessary distance parts (not drawn) can be mounted.
  • the bearing parts (20) can possibly be made out of sinter bronze. Because of the fact that the hinge between louvre (6) and flap (21) is as long as the louvre itself, it is necessary to support the louvres at the end only.
  • the ventilation system makes it possible to use elongated ventilator openings which ensures an efficient use of the opening.
  • the louvres (6) and flaps (21) can be manufactured of single extruded profiles and make use of appropriate materials like aluminum or plastic.
  • the strips of louvres (6) and flaps (21) can be made of transparant materials to have skylight entering the space.

Claims (1)

  1. Ventilationssystem für Räume unter Benützung natürlicher Zug bestehend aus Lamellen (6) welche befestigt sein innerhalb ein Umbau (5) und an der Aussenseite positionierte schwenkbarer Lüftungsklappen (21), welche zusammen die Luftstrom leiten durch die Ventilationsöffnung (3), dadurch gekennzeichnet, daß;
    - die feste Lamellen (6) zusammengestellt sein aus zwei extrudierte Profilen (7, 12) welche zusammengefügt sein mittels ein Plattenteil (11).
    - das Innenprofil (7) der feste Lamelle ein Ablaufrinne hat welche sich befind an derselbe Seite des Plattenteils (11) als der Lüftungklappe (21) und ein Tropfenablaufrinne (9) an der andere Seite davon;
    - das Außenprofil (12) der feste Lamelle ein Ablaufrinne (14) hat an der andere Seite der Plattenteil (11) in Bezug auf die Lüftungsklappe (21) so daß bei der normalen Ventilationsposition Niedersläge der Lüftungsklappe hinab in die Ablaufrinne niederfallt;
    - die Lüftungsklappen (21) zusammengestellt sein aus ein extrudiertes Profil (22) und Plattenteile (23, 24);
    - das gekrümmte Teil (26) der extrudierter Profil (22) von Lüftungsklappe (21) scharniert um ein cylindrisch Teil (19) der außen liegenden extrudierten Profilen (12) der feste Lamellen (6);
    - das system so ist ausgebildet daß bei kleinere Öffnungen ein regelbarer Ventilation entsteht mit ein Ventilationskoefficient (Cv), gemessen laut DIN 18232 teil 3, zwischen 0 und 0,6 der also Niederslägedicht ist, weil bei völlich geöffnete Lüftungsklappen, wie in der Fall eines Feuers, das Ventilationssystem ein Ventilationskoefficient (Cv) hat inzwischen 0,5 und 0,9.
