Definitions

  • the field of the invention is that of the ventilation of office premises, collective and individual dwellings.
  • the invention relates to an air distribution device for trunk, such as a rolling shutter box, a sunshade chest with adjustable blades or a boot awning.
  • the invention finds particular application in the ventilation of the main rooms or offices to windows equipped with shutters.
  • the quality of the air in the buildings is a determining factor for the health of their occupants. Indeed, human activity is at the origin of many emanations, such as water vapor generating moisture, CO2, or pollutant releases of multiple origins such as cooking, heating, use aerosols, or some pollutants from building materials, furniture, etc.
  • an extractor which is a mechanical device consisting of a motor-fan unit that extracts the stale air from the mouths installed in the service rooms and replaces it with new air that enters the building with air inlets connecting the main rooms with the outside air.
  • the air supply is a duct arranged through a window carpentry, or the wall of a rolling shutter box for window that allows the supply of fresh air for a sweep of the air in the accommodation.
  • a disadvantage of this known technique is that the resident receives directly the cold air flow to the right of the opening when it is close to the window.
  • a disadvantage of this technique is that the flow of cold air directly returned by the ceiling quickly falls in the immediate environment of the window on the occupants. Thus, the sensation of thermal discomfort persists.
  • the invention therefore particularly aims to overcome the disadvantages of the state of the art mentioned above.
  • the invention aims to provide an air distribution technique for trunk, for example for rolling shutter box, for sun shading chest with adjustable blades or for awning box banne, which limits or even removes the feeling of cold coming from the air vent, near a window surmounted by said trunk.
  • An object of the invention is also to provide such an air diffusion technique adapted to standard air inlets and in particular to self-adjustable and humidity-controlled air inlets.
  • Another objective of the invention is to provide such an air diffusion technique which complies with the NF DTU 68.3 P1-1-1 standard of 22 June 2013, on the replacement of residential or office premises with fresh air.
  • Yet another object of the invention is to provide such an air diffusion technique that is suitable for rolling shutter boxes, sun shading chests with adjustable blades or awning boxes, installed behind a concrete lintel, or directly under a concrete slab, or again doubling above the trunk.
  • An object of the invention is also to provide such an air diffusion technique that improves the quality of the fresh air and limits the entry of dust or pollens, for example.
  • Another object of the invention is to provide such an air diffusion technique that is simple to implement, and a reduced cost.
  • an air diffusion device adapted to be mounted on a trunk, such as a roller shutter box, a sunbreaker chest with adjustable blades, or an awning box, inside a room of a building or on a wall separating the box from the interior volume of a room, opposite an opening of air inlet formed in the trunk or in the wall, of substantially horizontal axis.
  • such a device comprises two air diffusion ducts each intended to receive substantially half of the air flow passing through the opening when the device is mounted opposite the opening, the ducts each having an inlet portion and an outlet mouth axis substantially perpendicular to that of the inlet portion, intended to be mounted facing the ceiling of the room, the inlet sections of the two ducts being substantially contiguous and the outlets of the two ducts being at least the width of the air intake opening.
  • the invention proposes dividing the flow of fresh air coming from outside that enters the room, and laterally redirecting this flow to prevent it from falling to the right of the entrance of air and thus limit the sensation of cold in winter, coming from the air vent.
  • the expression “substantially perpendicular” is understood to mean that the angle between the axis of the inlet portion and the axis of the outlet mouth is between 90 ° and 30 °. .
  • each of the ducts is profiled so that its section varies substantially continuously between the inlet portion and the outlet mouth of this duct.
  • the ducts are formed of a substantially prismatic shell at least partially open on a first side face, having two lights forming the outlet mouths on a second lateral face, and an element of partitioning mounted in the median plane of the shell parallel to its bases for forming a separation between the two ducts, the partitioning element having two air deflecting faces substantially symmetrical with respect to a plane of symmetry of the element of partitioning.
  • the flow of air is divided into two streams on either side of the median plane by the partitioning element which directs them laterally in the ducts in which they are channeled to the outlets.
  • the air deflecting faces comprise a succession of contiguous bands in pairs, extending in a horizontal direction, progressively inclined relative to the vertical.
  • the partitioning element can be easily manufactured at lower cost, by folding.
  • the air diffusion device comprises an air inlet guide intended to connect the opening to the inlet portions of the ducts, suitable for lodging in the shell, exhibiting a substantially vertical inlet section intended to be mounted opposite the opening and an outlet section intended to be mounted opposite the inlet portions of the ducts, inclined from 30 to 60 ° preferably inclined from 40 to 50 °, more preferably inclined 45 ° upwards with respect to the inlet section.
  • the outlet mouths are at least twenty-five centimeters apart.
  • each of the outlet mouths is equipped with a dust filter.
  • the outside air flow carrying dust or pollen is sanitized, which improves the comfort of residents.
  • the ducts are housed in a casing box having a longitudinal opening in its upper portion.
  • the air diffusion device comprises a vibrating speaker secured to the casing.
  • a wall of the cladding facade serves as a membrane to the vibration speaker on which it is plated, to convert the vibration acoustic wave.
  • the air diffusion device comprises at least one lighting source fixed to the box.
  • FIG. 1 an example of shutter box 1, integrated into the wall 2 of a building.
  • the roller shutter box 1 is formed of a box 10 of reconstituted wood whose inner walls are covered with a rock wool insulation 11.
  • This box 10 which is intended to accommodate the deck 12 of a roller shutter comprises a light 13 through which the slats 14 of the deck 12 exit or enter the box.
  • the box also comprises a inspection hatch 15 located inside the building which allows access to the mechanism of the shutter to ensure its maintenance.
  • This vertical inspection door 15 is crossed by two mortises 16 of substantially horizontal axis, equipped with an air inlet guide 17.
  • the two mortises 16 forming the air inlet opening can be replaced by one or more mortises of equivalent total surface, which guarantees an identical air flow rate.
  • the light 13 associated with the air inlet opening 16 and the air inlet guide 17 form an air intake which communicates the room of the housing or the office with the outside air allowing supply of fresh air for renewal by sweeping the indoor air.
  • This air diffusion device 20 comprises a partition element 21, a shell 22 and a casing box 23 which has in its upper part a longitudinal opening 24 intended to be oriented towards the ceiling of the room, during installation .
  • the partitioning element 21 is fixed substantially centered, vis-à-vis and / or above the air inlet guide 17 in the fresh air flow.
  • This partition element 21 in the general shape of "V" is formed of two deflector faces, that is to say that it comprises a succession of adjoining strips two by two. These successive bands are gradually inclined with respect to the vertical, in direction of the horizontal.
  • the intersections between each band form segments of straight lines parallel to each other.
  • the partitioning element 21 has a symmetry with respect to a vertical plane, as shown in the front view illustrated in FIG. figure 4 .
  • the axis of the "V" is substantially in the plane of symmetry of the two mortises 16.
  • the partitioning element 21 thus disposed, divides the main air flow 40 which enters through the air supply in two secondary flows 41a, 41b and laterally directs these secondary air flows 41a, 41b, thus breaking their speeds.
  • the assembly formed by the air inlet guide 17 and the partition element 21 is covered by the shell 22 folded sheet, closed at each end by a cheek.
  • This shell 22 is fixed horizontally along its longitudinal axis, applied to the inspection hatch 15 of the box 1.
  • the shell 22 pressed on the inspection hatch 15, separated in two parts by the partition element 21 thus forms on each side of this element 21 a duct which directs a portion of the fresh air flow entering the room, at a distal end of the shell 22 relative to the partition element 21 and the air inlet guide 17 located in central position.
  • the air diffusion device 20 mounted on the inspection hatch 15 is represented in plan view.
  • the shell 22 comprises two outlet mouths 50a, 50b substantially at its ends. distal ends, axes substantially perpendicular to that of the air inlet portion. These outlet mouths 50a, 50b serve to evacuate the two secondary air streams 41a, 41b channeled through the ducts 22.
  • each duct thus formed has a section much greater than the section of the air inlet opening 16 and the air inlet guide 17.
  • This section which varies substantially continuously between the inlet portion and the outlets 50a, 50b, contributes to slowing down the speed the air flow at the outlet through the longitudinal opening 24 of the air diffusion device 20 relative to the speed at the outlet of the air inlet guide 17.
  • FIG. 6 a sectional view of another exemplary embodiment of an air diffusion device 60 according to the invention, which incorporates an air filtering function.
