Definitions

  • the present invention relates to a ventilation system according to the precharacterising clause of Claim 1.
  • Such a ventilation system is generally -known in the state of the art.
  • Such ventilation systems are used, for example, in buildings where the surroundings thereof are subject to high noise pollution, hi such a case it is not possible to ventilate by means of simple windows.
  • Such ventilation systems are also used in buildings with controlled mechanical ventilation, where the incoming and outgoing quantity of air is accurately controlled.
  • the aim is for further limitation of the noise emanating from the surroundings that enters a building.
  • One possibility is to cover the intake pipe with soundproofing material.
  • Such an intake pipe extends t-hrough the wall that forms the link between the interior of the building and the surroundings.
  • the soundproofing material is porous, as a result of which undesirable bacteria, moulds and other life forms are produced, with or without the ingress of moisture.
  • JP 2003064797 there is a rigid, closed outer pipe that completely surrounds the sound duct.
  • the aim of the present invention is to provide a ventilation system by means of which a further limitation in the sound emanating from the surroundings is possible before it enters a building. Said aim is achieved with a ventilation system having the features of Claim 1.
  • the intake pipe as a frame with a relatively large opening surface area and to cover these openings with a thin-walled film or foil material.
  • T-his t-hin-walled film or foil material will give with the sound waves.
  • the film or foil material does not constitute a hard surface for sound waves.
  • limp material is understood to be a material that essentially transmits all sound from the interior of the intake pipe to the exterior thereof. This means that essentially no damping of sound by the film or foil material takes place. Moreover, preferably no reflection of the sound by the film or foil material, w-hich is fitted limply on the frame, takes place.
  • a pipe with a diameter of 105 mm provided with the limply fitted film or foil material is mentioned here as an example. Better damping can be obtained with such a pipe than with a pipe with an internal diameter of 100 mm and an external diameter of 160 mm, where optimised soundproofing material has been arranged between the interior and exterior of the pipe. This means that it is possible with the present invention to suffice with intake pipes of smaller diameter, as a result of which smaller holes have to be made in building constructions.
  • the thin-walled film or foil material can comprise any film or foil material -known in the state of the art, such as metallic material.
  • t-his preferably consists of plastic.
  • This plastic can comprise a woven fabric that is watertight and has limited permeability to gas.
  • the film or foil can also be gastight.
  • the thickness of the film or foil is as small as possible and is preferably below 0.2 mm and more particularly t-his thic-kness is approximately 0.05 mm.
  • the surface area of the openings at the location of the damping is preferably at least 50 %, and more in particular at least 80 %, of the total surface area. In the case of a wall without a cavity damping will be able to take place over the entire length thereof, whilst in the case of a cavity wall damping is preferably achieved at the location of the cavity.
  • the invention is particularly effective in damping frequencies between 75 and 10,000 Hz.
  • the relevant openings are preferably made at the location of the cavity. The sound can then be conducted into the cavity.
  • the openings can comprise a few large openings but also a large number of smaller openings.
  • the frame on which the film or foil material is fitted can be of particularly simple construction.
  • the frame consists of two spaced terminal rings with spacers extending between them.
  • the foil or film material can be fitted either on the inside or on the outside with respect to the frame. It is also possible, for example using injection moulding, to arrange the film or foil material "in the thickness" of the frame material.
  • the invention also relates to an intake pipe for a ventilation installation comprising a frame with two spaced circular terminal rings, spacers extending between them and a closing cylindrical film or foil material fitted on said frame, said film or foil material being fitted limply on said frame.
  • the diameter of the pipe is at least approximately 50 mm and in general approximately 100 mm.
  • the pipe can be produced in one piece. However, it is also possible to produce the pipe from a flat sheet consisting of a relatively thick part with windows and thinner film or foil material arranged thereon (to be arranged thereon). On site or at another location such a flat sheet can be folded to produce a pipe and the ends fixed to one another in some way or other. It is also possible to fit the film or foil material separately with respect to the frame.n such an embodiment the film or foil material is preferably fitted around the frame on the outside. In this context it is possible first to arrange the film or foil material in the opening in the wall, followed by the frame.
  • Fig. 1 shows, diagrammatically in cross-section, the ventilation system fitted in a building according to the invention
  • Fig. 2 shows, in perspective, the intake pipe according to the present invention.
  • Fig. 1 the ventilation system according to the invention is indicated in its entirety by 1.
  • This consists of a ventilation installation 8 that is fitted against the inner wall 3 of a cavity wall 2.
  • the outer wall is indicated by 4.
  • the ventilation installation comprises a fan 11 fitted in a housing.
  • This housing is provided with soundproofing material 12.
  • the housing is provided with an inlet opening 9 and an outlet opening 10.
  • Inlet opening 9 adjoins an intake pipe 6.
  • This intake pipe 6 is fitted in an opening 7, which extends through both the inner wall 3 and the outer wall 4.
  • the intake pipe 6 is provided with a terminal grating 5.
  • This pipe comprises a frame 13 consisting of terminal rings 14 and 15 and spacers 16 arranged between them.
  • the frame can consist of any material -known in the state of the art, such as a metallic material or plastic.
  • the frame is relatively rigid, so that a small size of the terminal rings 14, 15 and stays 16 can suffice. As a result large openings are produced and these are covered by plastic film 17.
  • Plastic film 17 is fitted limply on the frame 13 and is airtight. As a result it is not possible for gases to pass from the cavity between the walls 3 and 4 into the intake pipe 6.
  • the film material used is preferably plastic film and PNC material is mentioned as an example.

Abstract

La présente invention concerne un système de ventilation constitué d'un ventilateur et d'un tuyau d'admission. Le tuyau d'admission est constitué d'une structure de matière plastique relativement rigide. Cette structure délimite un espace cylindrique qui est bouchée au moyen d'un film plastique. Ce film plastique est adapté sur la structure de sorte des ondes sonores présentes dans le tuyau d'admission ne rencontre pas une surface dure et puisse être déviées sur la paroi contiguë.
