Definitions
- the invention relates to an installation for the natural ventilation of a room.
- Patent documents US2014 / 0113541 disclose building ventilation assemblies comprising a ventilation passageway installed at a door or at a doorway. a window.
- This ventilation passage communicates between the exterior of the building and the interior of said building so as to allow natural ventilation between the outside and the inside of said building. More specifically, it has a first end, closed by a hatch and opening into the building, and a second end opening outwardly of said building.
- a noise damper is installed in the ventilation passage to reduce noise.
- the damper comprises at least one control microphone installed to capture the noise in the ventilation passage, and at least one speaker provided with a vibrating membrane adapted to generate a counter-noise in the ventilation passage in response to noise sensed by the control microphone.
- the WISEMAN installation has some disadvantages. First, it is necessary to provide a hatch to release the first end of the ventilation passage and initiate natural ventilation. Handling and access to this hatch is not necessarily easy for some people, especially the elderly. In addition, this hatch can be the source of thermal leakage harmful to the building insulation.
- the installation is complex to build and install.
- the ventilation passage is either installed in the opening frame of the door or window, or between the frame and a wall masonry frame. It is therefore necessary to provide modifications to the frame of the door or the window and / or a masonry structure for the installation of the ventilation passage.
- the invention aims to remedy this state of affairs.
- an object of the invention is to simplify the design of the ventilation passage and its handling.
- Another object of the invention is to reduce the risk of thermal leakage at the level of the ventilation passage.
- Yet another object of the invention is to simplify the installation of the ventilation passage.
- the solution proposed by the invention is an installation for ventilating a room, said installation comprising:
- a room delimited by walls at least one door or window installed in one of the walls of the room, which door or which window comprises an opening frame supporting a glazed panel, which opening frame is movably mounted in a fixed fixed frame framing said opening frame,
- a ventilation passage equipping the door or window and communicating between the outside of the room and the interior of said room so as to allow natural ventilation between the outside and inside of said room, which passage has a first end opening in the room and a second end opening outside said room,
- an active noise absorber adapted to attenuate the sound waves propagating in the ventilation passage, which attenuation is achieved by the generation of a counter-noise which is superimposed on said sound waves
- the opening frame hermetically seals the first end of the ventilation passage so as to prevent any ventilation between the inside and the outside of the room by said ventilation passage,
- the opening frame releases the first end of the ventilation passage, which first end opens into the space between the profile of the opening frame of the profile of the frame frame, so as to allow natural ventilation between the inside. and the outside of the room only by said ventilation passage. It is now simply by sliding the door or the window that the user can very simply open or close the first end of the ventilation passage. In addition, it is no longer necessary to provide a hatch as in the installation WISEMAN, which simplifies the design of the ventilation passage. In addition, the door or the window hermetically closing the first end of the ventilation passage, thermal losses are reduced or zero at this level.
- the profile of the opening frame is preferably spaced apart from the profile of the sleeping frame by a distance of between 2 cm and 15 cm.
- the first end of the ventilation passage may extend vertically along the door or window, a length substantially corresponding to that of vertical sections of the opening frame.
- the noise absorber comprises at least one microphone arranged to capture the noise in the ventilation passage and at least one speaker adapted to generate a counter-noise in the ventilation passage in response to the noise picked up by the microphone.
- a switch is adapted to activate the noise damper.
- This switch can be adapted to be controlled by the movement of the door or the window so that when said door or said window passes from the closed position to the intermediate open position, said switch automatically activates the noise damper.
- the switch can also be adapted to automatically disable the noise damper when the door or window is in the closed position.
- the ventilation passage may be in the form of a duct attached to the wall of the room where the door or window is installed, outside said room.
- the ventilation passage may also be in the form of a duct integrated into the wall of the room where the door or window is installed, outside or inside said room.
- the duct has internal walls which delimit the ventilation passage, which walls are covered with a sound insulating material.
- the frame can be provided with at least one rail on which slides at least one profile of the opening frame, which rail is provided with a stop member when the opening frame is in the intermediate open position.
- a duct having an open face may be installed so that said open face is adjacent to the fixed frame, and located outside the space separating the profile of the opening frame from the profile of the fixed frame; a transparent plate extends between the opening frame and the frame, from the open face of the conduit to the opening frame, which plate extends said conduit to the first end of the ventilation passage; the duct and the transparent plate defining the ventilation passage.
- the ventilation passage has a form of baffle.
- the ventilation passage may have several superimposed channels parallel to each other.
- the internal walls of a duct defining the ventilation passage may be covered with a sound insulating material.

- the present invention relates to an installation for the natural ventilation of a room, which is characterized by a particular design of the ventilation passage and the sound damper it comprises.
- the installation comprises a local L delimited by walls P.
- This room can be a room of a house or office.
- the walls P are typically masonry walls.
- At least one door or window F is installed in one of the walls P of the local L. To simplify the understanding of the invention, the remainder of the description only mentions a window F.
- This window F is preferably a multi-glazed window, for example double glazing, but may be single glazed. It forms an interface between the interior of the room L and the outside of said room.
- the window F in itself is of the known type. It consists of one or more leaves V, V as illustrated in Figure 1.
- Each leaf V, V consists of an opening frame 30, 30 '(simply called "opening" in carpentry) formed by horizontal sections 30a , 30'a and vertical 30b1, 30b2, 30'b1, 30'b2 framing at least one glazed panel 4, 4 '.
- the opening frames 30, 30 ' have a generally rectangular shape, which borders the respective panels 4, 4' along its four sides. They are preferably identical.
- the opening frames 30, 30 ' are movably mounted in a frame 31 (simply called “frame” in joinery) fixed to the wall P.
- This frame 31 is secured to the wall P and more generally the shell or frame of the assembly where the window F is to be arranged. It is also formed by horizontal profiles 31a and vertical 31b1, 31b2 framing the opening frames 30, 30 '.
- the dimensions of the opening frames 30, 30 'in width are substantially equal to half that of the frame 31 which surrounds them. Their height dimensions are substantially equal to that of the frame 31, the thickness of the profiles close.
- the profiles 30a, 30'a, 30b1, 30b2, 30'b1, 30'b2, 31a, 31b1, 31b2 are rigid, made of metal such as aluminum or other, wood, plastic or by combining such materials.
- the window F is a sliding window. At least the leaf V is able to move by sliding laterally on at least one horizontal carrier rail 31c mounted in the frame 31, and in particular in its lower part.
- the opening frame 30 may comprise a or several trolleys with wheels or rollers, adapted to ensure its sliding in the rail 31 c.
- the opening frame 30 is movable between a closed position ( Figures 1 and 2) where it closes the frame 31 and an open position where it releases it.
- the open position provides natural ventilation between the inside and the outside E of the room L.
- the two leaves V, V are in the extension of one another.
- the vertical profile 30b1 side of the opening frame 30 penetrates into the corresponding vertical profile 31 b1 of the frame 31, these two sections solidarisant hermetically.
- these two profiles 30b 1, 31 b1 comprise mutual locking means for locking the leaf V in this position.
- no ventilation between the inside and the outside E of the room L is possible by the window F.
- the lateral vertical profile 30b1 of the opening frame 30 is separated from the corresponding vertical profile 31b1 of the frame 31, and deviates from the latter by a predetermined distance (for example between 2 cm and 15 cm , preferably 10 cm) when the leaf V slides. Natural ventilation is possible between inside and outside E of room L, through window F.
- a ventilation passage 1 is installed at the window F.
- This passage 1 is a device that combines with the window 1, without the need to change the latter.
- This passage 1 can therefore be installed on an existing window F which is already placed in a wall P.
- the passage 1 communicates between the outside E of the room L and the interior of said room so as to allow, if necessary, a natural ventilation between the outside E and inside said room.
- the manner in which this ventilation is made is explained below in the description.
- the passage 1 is in the form of a duct C reported on the wall P of the room L where the window F is installed.
- this duct C is preferably installed outside the room L. make invisible from the outside, this duct can be integrated in the wall P, although this arrangement requires prior work masonry.
- This conduit is for example made of metal such as aluminum, stainless steel or other, wood, plastic, glass to be transparent, or even combining such materials. To simplify the design, it is advantageously formed of folded sheets assembled together.
- the conduit C is fixed on the wall P by any suitable fastening means such as screws, glue, etc.
- the passage 1 has a first end 10 opening into the room L and a second end 12 opening to the outside E of said room. These ends are materialized by the distal and proximal ends of the duct C. They are advantageously located in two distinct planes, and preferably in two orthogonal planes, so that the passage 1 is in the form of a chicane, this configuration improving the natural ventilation.
- the first end 10 extends vertically along the window F, a length substantially corresponding to that of the vertical sections 30b1, 30b2. In this way, the ventilation can be carried out over the entire length of the window F. In FIG. 2, the first end 10 is situated in the same vertical plane as the opening frame 30, outside E of the window F.
- the ventilation passage 1 has several channels 1 a, 1 b, 1 n (n may vary from 2 to 15) superimposed parallel to each other. These different channels are independent and are for example delimited by plates or horizontal plates installed in the duct C. This design ensures a homogeneous distribution of the ventilated air flow over the entire length of the window F.
- each channel 1a, 1b, 1a has a length of between 20 cm and 50 cm.
- Their section can be square, rectangular or circular. The length of their diagonal or their diameter is for example between 5 cm and 10 cm.
- the ventilation passage 1 is not stepped, but has a single channel.
- This single channel extends in the form of a double baffle between the two ends 10 and 12 of the passage 1 (a baffle in the vertical plane of FIG. 7, and another horizontal baffle in the upper part of the conduit C), the first end 10 being disposed in the upper part of the duct C and the second end in the lower part.
- An inverse configuration is of course conceivable. This design aims to prevent any return of air in the duct C, which phenomenon can occur in the case of the ventilation passage 1 stage described above.
- the single channel provides unidirectional ventilation in line C.
- the window F hermetically closes the first end 10 of the ventilation passage 1 so as to prevent any ventilation between the inside and the outside E of the local L including any ventilation by said ventilation passage.
- the vertical profile 30b 1 side of the opening frame 30 is firmly attached to the corresponding vertical profile 31 b1 of the frame 31, the first end 10 of the ventilation passage 1 is closed by said opening frame, in particular by the glass panel 4. The air can not circulate in the conduit C.
- the leaf V slides so that the vertical profile 30b1 side of the opening frame 30 is spaced from the corresponding vertical section 31 b1 of the frame 31 of a predetermined distance (for example between 2 cm and 15 cm, preferably 10 cm) and is positioned vis-à-vis the side edge C1 of the duct C.
- the first end 10 of the ventilation passage 1 then opens into the space between the vertical profile 30b1 side of the opening frame 30 corresponding vertical profile 31 b1 of the frame 31. It is released so as to allow a natural ventilation between the inside and the outside E of the loca 1 L only through the ventilation passage 1. This natural ventilation is shown schematically in Figures 5 and 7 by the arrow drawn in the passage 1.
- the intermediate open position is reached when the lateral vertical profile 30b1 of the opening frame 30 is positioned vis-à-vis the lateral edge C1 of the duct C.
- a member 310c forming a stop when the opening frame 30 is in the intermediate open position.
- This element 310c is clearly visible in Figures 2 and 5 and is for example in the form of an elastomeric rib installed in the rail 31c.
- Figures 8 to 12 illustrate another embodiment where the glazed panel 4 is not partially closed by the conduit C, unlike the embodiment described above. Indeed, in the embodiment of Figures 1 to 7, the duct C partially covers the glazed panel 4 from the vertical section 31 b1 of the frame 31 to the side edge C1, which is likely to reduce the glass area total of the window F and thus the illumination of the local L.
- the duct C is adjacent to the dormant frame 31, without covering the glazed panel 4.
- the duct C has an open face 13 which is situated in a vertical plane containing the vertical profile 31 b1 of the fixed frame 31, this plane being perpendicular to the leaves V, V and therefore perpendicular to the frames 30 and 31.
- the open face 13 is adjacent to the frame 31, and located outside the space between the opening frame 30 of said frame 31 when the window F is in the intermediate open position.
- the open face 13 is delimited laterally on the one hand by the lateral edge C1 of the duct C, and on the other hand by the vertical section 31 b1 of the fixed frame 31.
- a transparent plate 14 extends between the opening frame 30 and the frame 31, from the open face 13 of the conduit C to the opening frame 30, so that said duct and said plate define the ventilation passage 1.
- the plate 14 is for example made of glass or plexiglass. It is formed by an angle or angle profile and has an L-shaped cross section.
- a first end 141 of the plate 14 is secured to the lateral end C1 of the duct C, for example by gluing.
- the other end 142 of the plate 14 is at a distance of approximately 5 cm to 20 cm from the vertical profile 31 b1 towards the glazing panel 4. This second end 142 is advantageously in contact with at least the horizontal sections 30a of the opening frame 30 , and if necessary with the glass panel 4.
- the plate 14 thus extends the conduit C to the first end 10 of the ventilation passage 1.
- the plate 14 is transparent, it does not reduce the total glazed area of the window F nor the illumination of the local L.
- the leaf V slides so that the vertical vertical profile 30b 1 of the opening frame 30 is spaced from the corresponding vertical profile 31 b1 of the fixed frame 31 by a predetermined distance (for example between 2 cm and 15 cm, preferably 10 cm) and is positioned vis-à-vis the second end 142 of the plate 14.
- the first end 10 of the ventilation passage 1 then opens into the space between the vertical profile 30b1 side of the opening frame 30 of the corresponding vertical profile 31 b1 of the frame 31 and allows a natural ventilation between the inside and outside E of the local L only through said passage.
- the space between the vertical profile 30b1 lateral of the opening frame 30 and the other vertical section 31b2 of the frame 31 which is opposite the vertical profile 31b1, is completely closed by the glazed panels 4 and 4 ', so that the air can not circulate at this level between the inside and the outside E of the room L.
- the user wishes to further open the leaf V, that is to say beyond the intermediate open position, there is a natural ventilation between the interior and exterior E of the room L not only through the ventilation passage 1, but also at the space between the lateral vertical profile 30b1 of the opening frame 30 and the second end 42 of the plate 14.
- the ventilation passage 1 has several channels 1 a, 1 b 1 n superimposed parallel to each other. These different channels are similar to those described above with reference to FIGS. 1 to 4.
- the ventilation passage has a single channel that is similar to that described above with reference to FIG. 7.
- a noise damper 2 is associated with ventilation passage 1. This damper is used for active or passive control of noise.
- An active damper 2 generates, in the ventilation passage 1, a sound level equivalent to the ambient sound level to be controlled, in particular noise originating from one or more noise sources located outside the room L. In practice, this active damper 2 generates a counter-noise which is superimposed on the sound waves propagating in the ventilation passage 1.
- the active noise damper 2 can be in the form of a piezoelectric actuator or a loudspeaker.
- a linear loudspeaker of the type described in US Pat. No. 6,285,773 is preferably used. (Carme) supra, and to which the skilled person can refer if necessary.
- This type of linear speaker can indeed be easily housed in a reduced volume and in particular in a narrow space, while having a performance comparable to that of a conventional speaker conical membranes.
- the geometric shape and the particular arrangement of the constituent elements of the linear loudspeaker offer a very satisfactory performance. In particular, given the long length of the membrane, it moves a large mass of air during its vibration, which provides a good performance in the low frequencies.
- This linear speaker is for example installed vertically over the entire length of the conduit C.
- the linear speaker can however be replaced by several circular speakers installed side by side in the duct C and especially, in the case where the duct is stepped, in each of the channels 1a, 1b, 1n.
- the linear speaker can however be replaced by several circular speakers installed side by side in the duct C and especially, in the case where the duct is stepped, in each of the channels 1a, 1b, 1n.
- ASCA loudspeakers marketed by the applicant.
- loudspeaker bearing the reference 22, is used that the latter is a loudspeaker as such (linear or circular) or a piezoelectric actuator.
- the noise damper 2 may comprise a single linear speaker 22 disposed on only one side of the duct C, or several circular loudspeakers.
- the choice of the number of loudspeakers and their arrangement in the duct C depends on the sound field to attenuate, by superposition, noises propagating in the ventilation passage 1, to increase the sound insulation when the window is in intermediate open position.
- the builder 22 comprises a membrane 220 adapted to vibrate and generate a counter-noise in the ventilation passage 1.
- An actuator 221 is associated with the membrane 220. This actuator 221 is adapted to induce a vibratory movement. to the membrane 220. It can be a piezoelectric actuator or more conventionally an actuator using an arrangement of magnets and coil electrically excited to cause the vibration of the membrane 220 which generates the noise.
- At least one microphone 21 is installed in the ventilation passage 1 to capture the acoustic signals propagating therein.
- the microphone 21 sends a signal representative of the noise in the ventilation passage 1 to a control electronics 23. Consequently, the control electronics 23 emits a control signal to the actuator 221 as a function of the acoustic signals picked up by the microphone. 21.
- the damper 2 thus increases the sound insulation of the window F while it is in the intermediate open position.
- the control electronics 23 can implement a feedback filtration (in English "FEEDBACK”) and / or a filtration by anticipation (in English "FEEDFORWARD”).
- FEEDBACK feedback filtration the microphone 21 is a control microphone, or an error microphone.
- the microphone 21 is an error microphone arranged near the first end of the ventilation passage 1 and another reference microphone is provided. 24 ( Figures 2, 5, 9, 12, 14 and 16) arranged near the second end 12 of said passage.
- the assembly of FIG. 16 is that described in the European patent
- EP0898774 (FRAUNHOFER) and the assembly of FIG. 17 is that described on US Patent 6963647 (FRAUNHOFER), which the skilled person can refer to when needed.
- a switch is adapted to activate the noise damper 2.
- the switch 5 is in the form of a toggle switch or pusher installed in the room L, on a wall P, which switch is of the type traditionally used for lighting. By manipulating this switch 5, the user can activate or deactivate the noise absorber 2, for example by controlling the power supply of the control electronics 23.
- a position sensor 50 ' may be installed on the vertical profile 30b1 lateral of the opening frame 30 and / or on the lateral edge C1 of the duct C or on the second end 142 of the 14.
- the position sensor 50 ' cooperates with the switch 5' so that the latter automatically activates the noise damper 2.
- This switch 5 ' can also be adapted to automatically disable the sound absorber 2 when the window F is in the closed position or it is not in the intermediate open position.
- the damper 2 may also be passive, that is to say it is adapted to absorb all or part of the sound waves propagating in the ventilation passage 1. To do this, it is advantageous that the internal walls of the duct C delimiting the ventilation passage 1 are covered with a sound insulating material. To further improve the reduction of noise in the ventilation passage 1, it is advantageous to combine an active attenuation by the use of the active damper 2 and a passive attenuation by the coating of all or part of the internal walls of the duct C.
- the damper 2 is passive.
- a flexible membrane 220 is simply suspended from the side walls of a cavity 223 formed in the conduit C.
- the membrane 220 closes the cavity 223 so as to be able to vibrate in the ventilation passage 1.
- the membrane 220 absorbs all or part of the sound waves propagating in the ventilation passage 1, to increase the sound insulation.
- the membrane 220 is for example formed by a film with elastic properties, such as an elastomer having an elastic power or a polyethylene film.
- the local L may be a particular passenger compartment, such as the passenger compartment of a motor vehicle, a train, or even an aircraft.
- the walls P are then for example made of sheets.
- the window F may comprise a single leaf V formed by the opening frame 30 mounted movably in the frame 31, or more than two leaves.
- the two leaves V, V may be able to move by sliding laterally in parallel planes on horizontal support rails mounted to the lower part of the fixed fixed frame 31.
- the leaf V can move by sliding vertically on one or more vertical load-bearing rails mounted in the side portion of the frame 31, and in particular in the vertical sections 31 b.
- the frames 30 and 31 are preferably of rectangular or square shape, but may be of polygonal shape, have one or more curved edges, etc.
- the duct C forming the passage 1 can be installed inside the room L.
- the natural ventilation in the passage 1 can be done from outside the room L to the outside E; or from inside the room L to the outside E.
- the element 310c forming an abutment may be in any other form that is suitable for those skilled in the art.
- the ventilation passage 1 and the noise damper 2 may be associated with an oscillating window where the opening frame 30 is rotatably mounted in the frame 31.
