Definitions

  • the present invention relates to an air intake system for the interior ventilation of a building, in particular for a dwelling or a tertiary building.
  • Buildings receiving people in particular housing or tertiary premises such as schools or offices, generally include a ventilation system for the various rooms to renew the air, comprising a system for extracting the air from the premises, and air inlets coming from the outside to compensate for this extraction.
  • the main objective of renewing the air in the rooms is to remove pollutants from the air linked to the presence of occupants, the presence of the equipment or machines used in these premises, as well as those emitted by the building itself. Even. Air pollutants are in particular carbon dioxide CO2, humidity and volatile organic compounds called “VOCs”.
  • the ventilation of the premises can be natural, with air ducts from different rooms to the outside, which have a thermal draft activated by the natural pressure difference when the air is colder outside.
  • the outside temperature is higher, the pressure differential between the inside and the outside is lost, and the air flow may be insufficient.
  • the ventilation of the premises can also be carried out by a controlled mechanical ventilation called "VMC", comprising a turbine driven by a continuously rotating electric motor, which generates a vacuum for activate the flow in the air ducts opening to the outside.
  • VMC controlled mechanical ventilation
  • the ventilation can have variable operation, in particular having a fixed, modulated or intermittent flow rate.
  • an intermediate ventilation system also called hybrid ventilation
  • the speed of the turbine can be automatically adjusted according to the outside temperature which activates natural ventilation.
  • the air is extracted through extraction vents placed in technical rooms, such as the kitchen, the toilets or the bathroom, and the air is introduced into living rooms, such as the living room, the office, the living room or the bedrooms.
  • Air inlets generally form grilles placed above doors or windows, or at the top of walls, which first scans living rooms, then technical rooms where air is extracted. , generally representing rooms where pollutants are more numerous.
  • the air intake grilles have a surface fixed to the wall surrounding an opening to the outside, and a shape which directs the air inwards including in some cases a system for adjusting the passage section which can be partially or fully closed. This adjustment can be manual, or automated with automatic modulation according to the detection of a pollutant.
  • the object of the present invention is in particular to avoid these drawbacks of the prior art.
  • this spacer is then fixed on the wall in place of the device without any modification of this wall.
  • the assembly is done in a simple, fast and economical way.
  • the air intake system according to the invention can also include one or more of the following characteristics, which can be combined with one another.
  • the direct passage of air from the spacer towards the interior of the building is designed to be directed upwards. In this way the constant air flow is not directed towards the users.
  • the two faces of the spacer provided for the fasteners are parallel.
  • the air intake device finds the same orientation as it has without the spacer.
  • the two faces of the spacer provided for the fixings form an angle which tilts the air inlet device downwards.
  • the angle formed by the two faces of the spacer may be between 15 and 45 °.
  • the air inlet device comprises a means for adjusting the flow rate. Whatever the setting of the flow rate, the constant air flow is then obtained as a minimum.
  • the flow rate adjustment means may include an automatic mechanism based on a measurement of pollutants in the air.
  • the main air flow is designed to be directed upwards.
  • the air inlet device and the spacer can include aligned holes allowing fixing to the wall with the same screws. In this way, no specific fixing means are added for the spacer, the assembly being fixed in the same way as the air inlet device alone.
  • the outer contour of the spacer corresponds to that of the air inlet device. This gives an assembly having aligned exterior surfaces, which is aesthetic.
  • the figure 1 presents an exterior wall of a building 2 comprising an opening towards the exterior 4 extending horizontally, receiving on its exterior wall disposed on the front side indicated by the arrow "AV", a canopy 6 disposed above this opening protecting it the entry of rain or snow.
  • the air inlet device 10 comprises a rigid structure of thin thickness, having a constant cross section, comprising a lower box of rigidity 14 of substantially square section which is fitted below the opening 4.
  • An adjustable opening valve 18 is held by a longitudinal hinge disposed just below the opening 4, near the wall of the wall 2, which is fixed above the box 14.
  • the valve 18 comprising a slightly rounded shape turned backwards, a in the closed position presented figure 1a its upper edge which bears on a longitudinal sealing bar 20.
  • valve 18 In the open position presented figure 1b , the valve 18 retracted rearwardly bears on a substantially parallel fixed partition 16, which connects the rigidity box 14 to the rear face 12.
  • valve 18 In the closed position the valve 18 completely closes the air inlet facing the opening 4. In the open position the valve 18 forms a progressive guide of the air flow F coming from the outside to direct it upwards. , to avoid pointing it at people in the room.
  • the control of the adjustable valve 18 can be manual or motorized.
  • the figures 2, 3, 4a and 4b present an additional air inlet spacer 30 comprising a flat front face fixed to the wall of the wall 2, and a parallel flat rear face receiving in an adjusted manner along the same contour, the flat front surface of the air inlet device. air 10.
  • the flat front surface of the air inlet device 10 may have a different contour from that of the air inlet spacer 30.
  • the spacer 30 comprises in the lower part a lower box 32 fitted at the bottom of the opening 4, which receives the support of the rigidity box 14 of the air inlet device 10.
  • the spacer 30 comprises in the upper part a flow guide 34 having an aerodynamic profile, comprising a tip facing forward, which separates above a small section allowing a minimum constant air flow F1 directed upwards, and below a large section allowing a main air flow directed horizontally towards the adjustable valve 18 of the air inlet device 10.
  • the small cross section of the constant air flow F1 smaller than the large cross section of the main air flow F advantageously comprised between 15 to 50% of this large cross section, in particular represents approximately 40% of this cross section.
  • the spacer 30 has at each longitudinal end a tip 40 which comes beyond the air passage, having a bore receiving a fixing screw for fixing to the wall of the wall.
  • the outer canopy 6 also comprises end pieces 40 each having a bore receiving a fixing screw on the outer wall of the wall 2.
  • the air inlet device 10, the spacer 30 and the outer canopy 6 comprise partitions or transverse bars 42 regularly spaced, which stiffen these elements in order to avoid their deformation, without hindering the air flow. parallel to these shapes.
  • all the elements 6, 10, 30 are formed by molding a plastic material, which makes it possible to produce complex shapes in a simple and economical manner.
  • a spacer 30 is easily added under a standard adjustable air inlet device 10, which gives at least whatever the state of this inlet the constant flow F1 directed upwards. As a variant, this constant flow F could be directed downwards.
  • a standard air inlet device 10 comprising an automated means for adjusting its flow rate, for example with an integrated sensor for measuring pollutants.
  • the figures 5 and 6 present an air inlet device 10 according to a variant, comprising an adjustable flat opening valve 18, presented in the semi-open position. Compared to the previous air intake device presented figure 2 , this air inlet device 10 has a reduced height, and a greater width ending towards the rear in a rear face 12 which is strongly rounded.
  • a flat fixed internal partition 16 forms a rear stop of the adjustable valve 18 when it is fully open, which comprises on its rear face a succession of parallel horizontal ribs 50.
  • the figures 7 and 8 have a spacer 30 comprising the air outlet of the constant flow F1 facing upwards, and the rear face which is inclined relative to the front face downwards, at an angle advantageously between 15 and 45 °, which is in this example of 30 °.
  • This spacer 30 has at its base an almost zero width, which gives it minimum bulk.
  • the figure 9 presents as a function of the setting R of the opening valve 18, ranging from an almost closed position 0 to a fully open position 1, the air flows D given by all the air inlets.
