Definitions

  • the subject of the invention is an installation for the natural ventilation of a room provided with a noise damper.
  • the invention also relates to a ventilation passage suitable for providing natural ventilation between the outside and the inside of a room.
  • This ventilation passage communicates between the exterior of the building and the interior of said building so as to allow natural ventilation between the exterior and interior of said building. More precisely, it has a first end, closed off by a hatch and opening into the building, and a second end opening out to the outside of said building.
  • a sound absorber is installed in this ventilation passage to reduce noise.
  • the damper includes at least one monitoring microphone installed to pick up noise in the ventilation passage, and at least one loudspeaker provided with a vibrating membrane adapted to generate counter noise in the ventilation passage in response to the noise. picked up by the monitoring microphone.
  • the WISEMAN installation has certain drawbacks. First of all, it is necessary to provide a hatch to release the first end of the ventilation passage and initiate natural ventilation. The handling and access to this hatch are not necessarily easy for some people, especially the elderly. In addition, this hatch can be the source of thermal leakage harmful to the insulation of the building.
  • the ventilation passage is either installed in the opening frame of the door or window, or between the fixed frame and a masonry wall. It is therefore necessary to provide substantial modifications to the opening frames of the door or window and / or a masonry structure for the installation of the ventilation passage.
  • the invention aims to remedy this state of affairs.
  • an objective of the invention is to simplify the design of the ventilation passage as well as its handling.
  • Another objective of the invention is to reduce the risks of thermal leakage at the level of the ventilation passage.
  • Yet another objective of the invention is to simplify the positioning of the ventilation passage.

More particularly, in the closed position, the opening frame 30 is hermetically secured to the fixed frame 31 so as to prevent any ventilation between the interior and the exterior E of the room L through the door or the window F. And in the open position, the opening frame 30 is separated and separated from the fixed frame 31 so as to allow natural ventilation between the interior and the exterior E of the room L through the door or the window F.
