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 gullies and where the in-between distance of the louvres and valves prohibit the weather entries to pass along the gullies and enter the ventilated spaces.
  • the ventilation system provides the possibillity to open the valves 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 valves are well known.
  • the invention provides a system where control valves are used which are part of the sealing against precipitation when used as a ventilation control. While in case of fire the valves can be fully opened.
  • a universal ventilation system requires an air passage with a C v -value of 0 to 0.6. In case of fire 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 valve (21) on the cylindrical part (19).
  • the valve (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.
  • Fig. 1 the position of the valves (21) is at normal ventilation. In this position precipitation caught by valve (30) will be led to gutter (14). Precipitation which passes valve (30) will be caught by gutter (8) and gutter (14) of the next louvre (6). The precipitation is lead out by holes (not drawn) near the end of the louvres (6).
  • At (31) is indicated the position of the valve with maximum passage in case of fire.
  • 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 valve (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 valves (21) can be manufactured of single extruded profiles and make use of appropriate materials like aluminum or plastic.
  • the strips of louvres (6) and valves (21) can be made of transparant materials to have skylight entering the space.
