Description

PROFILE FOR MODULAR SPACES USING AN AERAULIC PLENUM TECHNICAL FIELD OF THE INVENTION

[0001] The invention relates to the field of technical ceilings for grid rooms, in particular a profile for managing the partitioning of modular rooms.

[0002] A technical ceiling is a structure that can take the form of a false ceiling and has, in addition to a cladding role, a technical role related to the purpose of the premises.

[0003] The technical ceiling according to the invention has the role in particular, but not exclusively, of contributing to the thermal comfort of the room in which it is placed, namely the heating, ventilation and air conditioning, commonly called HVAC, while allowing easy management of partitioning modifications, that is to say the additions or removals of dividing partitions without the necessary dismantling of the technical ceilings and without the necessary modifications of the HVAC installations connected to these technical ceilings. STATE OF THE ART

[0004] It is known to combine technical stretch ceilings with ventilation or ambient treatment equipment (heating, air conditioning, dehumidification) to allow air circulation linked to the air conditioning and / or ventilation of a room concerned. As an example, international patent application WO 2018 / 037184 A1 (SCHERRER JEAN MARC [FR]; LANG DAMIEN [FR]) can be cited. The system described in this application uses hot or cold pulsed air in the plenum between the upper slab of the room and a stretched canvas mounted on peripheral profiles which include a passage slot arranged to allow the diffusion of air from the plenum towards the interior of the room. Heating and cooling are done by recycling the air from the room, via an air conditioning unit. The recycled air, as well as the fresh hygienic ventilation air, are therefore blown into the plenum.The technical ceiling diffuses heating and cooling, partially, via thermal radiation from the canvas which cools or heats up on contact with the air blown into it. plenum, but also by convection, via the air flow, hotter or colder than the ambient air, blown around the edge of the room. It therefore operates on a mix of radiation and convection with a proportion of radiation generally less than 50%.

[0005] International patent application WO 2020 / 053524 A1 (NORMALU [FR]) discloses a radiant technical ceiling for heating, air conditioning and ventilation of a room, characterized in that it comprises at least one stretched fabric allowing all or part of the light and / or thermal radiation to pass through, the fabric extending between walls and being arranged to delimit, with an upper slab called a plenum, a space, and one or more radiating elements, formed for example of metal panels, and arranged to allow the circulation of a heat transfer / cold fluid, the one or more of the elements being arranged in the space provided between the stretched fabric and the upper slab. The technical ceiling may, depending on its implementation, be a false ceiling or a stand-alone island.

[0006] Other systems called "forced air systems" use conventional false ceilings, for example made of plaster, removable panels or metal elements, in which air supply and / or suction grilles are installed, connected via air ducts to the HVAC machinery, i.e. the air conditioning units required to produce treated air.

[0007] Treated air means cooled or heated and / or ventilated and / or dehumidified and / or humidified air.

[0008] For these systems, a space called a "plenum" is also included between the false ceiling and the natural slab of the room served. This plenum is used in particular for the passage of air ducts.

[0009] In many cases, the entire volume of the plenum is used to draw ambient air from the room (this is called a negative pressure plenum) or to blow the treated air into the room (this is called an overpressure plenum). The plenum then acts as an air duct, either for suction or for blowing.

[0010] Grid-like spaces, such as many office spaces, require regular changes to the partitioning. Thus, depending on the needs of the occupants, open spaces or meeting rooms are converted into individual offices and vice versa. Their grid, that is to say the places where it is possible or not to install a dividing partition, are generally lengths extending from the exterior facade to the central corridor of the building, the width of which varies between 1m and 2m. A partitioned interior space is composed of at least 2 grids and can extend up to an unlimited number of grids when one wishes to create a completely open space.

[0011] When using a technical stretch ceiling as described in international patent application WO 2018 / 037184 A1, the technical stretch ceilings must be dismantled and replaced each time the partitioning is changed, which makes the process very difficult in practice. When using "stretch ceilings" comprising grids, i.e. a ceiling installed over the entire surface of the room with self-supporting partitions stopping under the lower face of the stretch ceiling, the operation requires moving certain grids, but this is sometimes easier. However, acoustic problems remain; in fact, for partitions stopping under the stretch ceiling delimiting the plenum, no acoustic barrier is ensured at the plenum level between two partitioned spaces, thus there are problems of noise transmission and confidentiality from one room to another. BRIEF DESCRIPTION OF THE INVENTION

[0012] The present invention aims to propose profiles for modular spaces to be installed at the level of technical ceilings (stretch ceilings, plaster ceilings, removable ceilings, etc.).

[0013] Installed according to a pre-defined framework, these profiles allow for the installation or not of a dividing partition without the need to dismantle the technical ceilings and without the need to modify the HVAC installations connected to these technical ceilings.

[0014] When a partition is inserted into the profile, the profile, occupying the entire height of the plenum, acts as a sound barrier. When no partition is installed, the profile has a finishing cap and the air from the plenum can circulate freely through the profile.

[0015] The technical ceiling according to the invention has the role, in particular, but not exclusively, to contribute to the thermal comfort of the premises in which it is located, namely heating, ventilation and air conditioning (HVAC) while allowing easy management of partitioning modifications, i.e. additions or removals of dividing walls, without the need to dismantle the technical ceilings and without the need to modify the HVAC installations connected to these technical ceilings.

[0016] In particular, the present invention proposes to provide a modular or grid-like room to be treated provided with a ceiling or slab and a false ceiling visible from the room, delimiting an air plenum zone, said air plenum being in overpressure or under depression of treated air, the treated air being heated or cooled and / or ventilated and / or dehumidified air, a modular partitioning management profile comprising an upper zone for attachment to the ceiling of the room, two lateral wings provided with lateral slots defining a hollow interior space and where the lateral wings are extended by attachment elements for false ceilings, where said modular partitioning management profile defines plenum zones and is: - be configured to allow the passage of treated air between several air plenum zones; - or in that said profile is either adapted to accommodate in its hollow interior space a modular separation partition preventing any passage of treated air between different air plenum zones of two different partitioned interior spaces delimited by said modular separation partition.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as generally understood by those skilled in the art to which the subject matter pertains. As used herein, the following definitions are provided to facilitate understanding of the present invention.

[0022] The term "include or comprises" is generally used in the sense of including, that is, allowing for the presence of one or more features or components.

[0023] The presence of broad words and phrases such as "one or more," "at least," "but not limited to," or other similar expressions shall not be construed to mean that the narrowest interpretation is intended or required in cases where such broad phrases may be absent.

[0024] The term "treated air" means air that is cooled or heated (so as to meet the cooling or heating needs of a room) and / or provided with a supply of fresh outside air so as to ensure the hygienic ventilation of the room and / or humidified or dehumidified so as to ensure the hygrometric management of a room.

[0025] “Reversible” means that the system can operate in heating or cooling mode.

[0026] Advantageously, the stretched canvas contains a plant-based plasticizer, for example of the “Bio-sourced” type. The stretched canvas thus has remarkable ecological characteristics.

[0027] The present invention relates in particular to a modular or grid-like room to be treated provided with a ceiling or slab (10) and a false ceiling (13) visible from the room, delimiting an air plenum zone (9), said air plenum being in overpressure or under pressure of treated air, the treated air being heated or cooled and / or ventilated and / or dehumidified and / or humidified air, a modular partitioning management profile (1) comprising an upper attachment zone (4) to the ceiling (10) of the room, two lateral wings (11 A and 1 IB) provided with lateral slots (3), defining a hollow interior space (12) and where the lateral wings (11 A and 1 IB) are extended by attachment elements (2) for false ceilings (13), and where said modular partitioning management profile (1) comprises ... modular partitioning defines plenum zones (9 A), (9B), (9C), (9D) and (9E) and is: either configured to allow the passage of treated air between several aeraulic plenum zones (9B, 9C and 9D); or adapted to accommodate in its hollow interior space (12) a modular separation partition (7) preventing any passage of treated air between different aeraulic plenum zones (9 A) and (9B) or (9D) and (9E) of two different partitioned interior spaces (8A), (8BCD) and (8E) delimited by said modular separation partition (7).

[0028] Preferably, said modular partition management profile (1) further comprises a compressible insulator (5) ensuring airtightness between the modular partition wall (7) and said modular partition management profile (1).

[0029] Advantageously, when a modular partition wall (7) is absent, a finishing cover (6) is inserted into the hollow interior space (12) of said modular partitioning management profile (1) on the surface visible from the room to be treated, said finishing cover (6) preventing the passage of treated air from the air plenum (9BCD) to the partitioned interior space (8 BCD).

[0030] According to one embodiment of the invention, the modular partition wall assembly (7), modular partition management profile (1) and compressible insulation (5) form an acoustic / sound barrier between the partitioned interior spaces (8A), (8BCD) and (8E).

[0031] Advantageously, the false ceiling (13) is a stretched canvas (15).

[0032] According to another embodiment of the invention, the false ceiling (13) comprises grilles (14) for blowing or sucking treated air.

[0033] According to a preferred embodiment of the invention, said stretched canvas (15) comprises a peripheral attachment profile (18) allowing air to pass between the plenum and the partitioned interior space.

[0034] Advantageously, the treated air blowing or suction grille (14) is connected to an air duct (16) connected to an air treatment unit (17).

[0035] Preferably, the stretched canvas (15) has micro-perforations. These ensure sound absorption, thus improving the acoustics of the room.

[0036] The overall system then allows the room to be lit via uniform diffusion across the entire ceiling surface and provides protection against the deposit of dust and insects which could settle on the canvas visible on the underside.

[0037] According to one embodiment, said second canvas as well as the stretched canvas have a maximum thickness of 5 mm. Preferably, the thickness of these two canvases is less than 2 mm and ideally less than 1 mm.

[0038] According to another embodiment, the technical ceiling constitutes a false ceiling. DETAILED DESCRIPTION OF THE FIGURES

[0039] Figure 1 illustrates a perspective view of the modular partitioning management profile (1) of the invention. This comprises an upper attachment zone (4) to the natural ceiling of the room and two side wings (11 A and 1 IB) provided with side slots (3).

[0040] The side wings (11 A and 1 IB) are extended by hanging elements (2) for false ceilings.

[0041] When the modular partition management profile (1) does not accommodate a dividing partition, it can be closed using a finishing cover (6) snapped onto its lower face.

[0042] Figure 2 illustrates a longitudinal section of premises equipped with 4 modular partition management profiles (1). For 2 of them, the hollow interior space (12) formed between the side wings (11 A and 1 IB) is closed by a finishing cover (6). The other two accommodate at the level of the hollow space (12) a separating partition (7) installed in contact with the compressible insulation (5) ensuring the seal between the separating partition (7) and the modular partition management profile (1).

[0043] False ceilings (13) are installed over the entire surface area of ​​the premises and secured to the false ceiling attachment elements (2) of each modular partitioning management profile (1).

[0044] Thus configured, the premises are equipped with 3 partitioned interior spaces (8A, 8BCD and 8E); the partition wall assembly (7), modular partition management profile (1) and compressible insulation (5) forming a sealed element installed from the floor of the room to the ceiling (10) of the room, it acts as a sound barrier between each partitioned interior space (8A, 8BCD and 8E).

[0045] This assembly obstructs the hollow interior space (12) of the modular partitioning management profile (1), it prevents any passage of air between the plenums of the 2 different partitioned interior spaces, for example between the plenums (9 A) and (9B) of the partitioned interior spaces (8A) and (8BCD).

[0046] The plenums (9B, 9C and 9D) equipping the partitioned space (8BCD) communicate aeraulically, that is to say that the air is free to pass from one plenum to the other thanks to the lateral slots (3) of the modular partitioning management profiles (1), on the other hand the finishing covers (6) prevent the passage of air from the plenums (9 A, 9B and 9C) to the partitioned space (8BCD).

[0047] Thus, in this configuration, the plenums equipping the same partitioned space form the equivalent of the same air plenum which can operate under overpressure or under depression, for example the plenums (9B, 9C and 9D) of the partitioned interior space (8BCD).

[0048] Furthermore, the plenums (operating under overpressure or under vacuum) of two different partitioned spaces are sealed from each other.

[0049] Figure 3 shows a cross-section of a technical stretch ceiling installation according to the invention described in WO 2018 / 037184 A1, in which the plenum is used under overpressure.

[0050] The false ceiling (13) is a stretched ceiling (15) secured to peripheral hanging profiles with slots (18). An air treatment unit (17) is connected by an air duct (16) to an air suction box (19) which allows ambient air to be sucked in through the peripheral hanging profile (18) located on the right of the figure.

[0051] The air treated by the air treatment unit (17) is then blown into the plenum (9) causing an overpressure in the latter. The treated air is then diffused towards the partitioned interior space (8) through the peripheral attachment profile (18) located on the left of the figure.

[0052] Figure 4 shows a cross-section of a technical ceiling installation with integrated grids (14) in which the plenum is used in overpressure.

[0053] The false ceiling (13) occupies the entire surface area of ​​the room. An air treatment unit (17) is connected by an air duct (16) to an air intake grille (14) located on the right of the figure, which allows the ambient air to be drawn in.

[0054] The air treated by the air treatment unit (17) is then blown into the plenum (9) causing an overpressure in the latter. The treated air is then diffused towards the partitioned interior space (8) through a blowing grille (14) located on the left of the figure.

[0055] Figure 5 represents a cross-section of a technical stretch ceiling installation according to the invention described in WO 2018 / 037184 A1 in which the plenum is used in depression.

[0056] The false ceiling (13) is a stretched ceiling (15) secured to peripheral hanging profiles with slots (18). An air treatment unit (17) is connected by an air duct (16) to an air blowing box (19) which allows the treated air to be blown through the peripheral hanging profile (18) located on the left of the figure.

[0057] The suction of the air treatment unit (17), connected directly to the plenum (9) causes a depression in the latter. The ambient air from the partitioned interior space (8) is then sucked in through the peripheral attachment profile (18) located on the right of the figure.

[0058] Figure 6 shows a cross-section of a technical ceiling installation with integrated grids (14) in which the plenum is used in depression.

[0059] The false ceiling (13) occupies the entire surface area of ​​the room. An air treatment unit (17) is connected by an air duct (16) to an air blowing grille (14) located on the left of the figure, which allows the treated air to be blown towards the partitioned interior space 8.

[0060] The suction of the air handling unit (17), connected directly to the plenum (9), causes a depression in the latter. The ambient air of the interior space partitioned (8) is then sucked through a suction grid (14) located on the right of the figure.

[0061] Figure 7 represents a perspective of premises equipped with partition management profiles and stretched technical ceilings according to the invention described in WO 2018 / 037184 A1. It notably shows the 4 modular partition management profiles (1) present in the longitudinal section of Figure 2 as well as the peripheral hanging profile (18) present in the cross sections of Figure 3 and Figure 5.

[0062] In this example, the peripheral hanging profiles (18) are installed along the exterior wall, between each modular partition management profile (1).

[0063] Figure 8 completes Figure 7, by showing the air supply (respectively suction) networks (16) connected to the plenums. In this example, an air supply (respectively suction) network (16) is connected every 3 frames, i.e. every 3 plenums delimited by a modular partitioning management profile (1), in this example, on the plenum (9 A), (9C) and (9E).

[0064] When the plenums operate with overpressure of treated air (respectively with depression for the suction of air towards the air treatment unit (17)) all of the peripheral attachment profile portions (18) of the same partitioned space, for example the 3 portions of the partitioned space (8BCD) allow the treated air to be blown towards the room (respectively to suck in the ambient air) and this regardless of the frame on which the blowing air duct (16) (respectively the air suction air duct (16)) is connected.

[0065] Figure 9 represents a perspective from another angle of the premises equipped with technical stretched ceilings according to an embodiment of the invention as described in WO 2018 / 037184 A1.

[0066] In particular, we can distinguish the modular partition management profiles (1), whose lateral slots (3) are closed by the insertion of a separation partition (7) and those equipped with a finishing cover (6) which allow the plenums located on either side of the partition management profile (1) to communicate. aeraulically via the unobstructed side slots (3).

[0067] It would thus be very easy to imagine a change in the configuration of the premises, for example by moving the partition wall (5) currently inserted in the profile (1) delimiting the plenums (9 A) and (9B). This profile would then be fitted with a finishing cover (5). The wall could, for example, be moved to the level of the profile (1) delimiting the plenums (9B) and (9C) by first removing the finishing cover fitted to the profile (1).

[0068] In this example, each of the new partitioned spaces (8AB) and (8CD) would be equipped with communicating plenums (9 AB) and (9CD) and connected to an air duct (16) for blowing treated air (respectively an air duct (16) for sucking air). The sound barrier between the spaces (8 AB) and (8CD) as well as the seal between the plenums (9 AB) and (9CD) is ensured by the insertion of the partition wall (7).

[0069] Thus, it can be seen that the air treatment and sound insulation of the new spaces (8AB) and (8CD) would be functional without any intervention at the level of the HVAC installations or the air ducts (16) and without any necessary dismantling of the false ceilings (13), making the operation particularly easy, which is one of the aims of the present invention.

[0070] Figure 10 shows a perspective of premises equipped with technical ceilings with grilles (14) as well as air ducts (16) supplying the various plenums.

[0071] In this configuration, an air supply (respectively suction) network (16) is connected every 3 frames, i.e. every 3 plenums delimited by a modular partitioning management profile (1), in this case, on the plenum (9 A), (9C) and (9E).

[0072] When the plenums operate with overpressure of treated air (respectively with depression for the suction of air towards the air treatment unit (17)) all the grilles (14) of the same partitioned space, for example the 3 grilles (14) of the partitioned space (8BCD) allow the treated air to be blown towards the room (respectively to suck in the ambient air) and this whatever the frame on which the blowing air duct (16) (respectively the air duct (16) air suction) is connected.

[0073] Figure 11 shows a perspective from another angle of rooms equipped with technical ceilings with grilles (14) as well as air ducts (16) supplying the various plenums.

[0074] In particular, a distinction is made between modular partition management profiles (1) whose lateral slots (3) are closed by the insertion of a separation partition (7) and those equipped with a finishing cover (6) which allow the plenums located on either side of the partition management profile (1) to communicate aeraulically via the unclosed lateral slots (3).

[0075] It would thus be very easy to imagine a change in the configuration of the premises, for example by moving the partition wall (5) currently inserted in the profile (1) delimiting the plenums (9 A) and (9B). This profile would then be fitted with a finishing cover (5). The wall could, for example, be moved to the level of the profile (1) delimiting the plenums (9B) and (9C) by first removing the finishing cover fitted to the profile (1).

[0076] In this embodiment, each of the new partitioned spaces (8AB) and (8CD) would be provided with communicating plenums (9 AB) and (9CD) and connected to an air duct (16) for blowing treated air (respectively an air duct (16) for sucking air). The sound barrier between the spaces (8 AB) and (8CD) as well as the sealing between the plenums (9 AB) and (9CD) is ensured by the insertion of the separation partition (7).

[0077] Thus we see that the air treatment and sound insulation of the new spaces (8AB) and (8CD) would be functional without any intervention at the level of the HVAC installations or the air ducts (16) and without any necessary dismantling of the false ceilings (13) making the operation particularly easy.
