    COMPONENT OF A MODULAR RADIANT CEILING AND CORRESPONDING CEILING
    The invention relates to the technical field of false ceilings used to adjust the air temperature or ambient temperature of a room.
    A false ceiling is conventionally made from a plurality of plates or slabs, fixed on suitable supports, a volume being thus defined between the false ceiling and the ceiling of the room (called plenum).
    Systems have been developed to ensure the thermal comfort of a room using this volume.
    Mention may in particular be made of document EP 1 167 889 which describes a process in which air is injected into the volume of the false ceiling, this air circulating in this volume to be heated or cooled there by appropriate means, before be introduced into the room to be conditioned by an opening in the false ceiling.
    The air in the false ceiling can be heated by means of hot plates placed above the upper face of the false ceiling.
    It can be cooled by means of cooling also arranged in the false ceiling volume, before the opening for introducing air into the room.
    This method and this device provide satisfaction.
    However, they have the disadvantage of requiring an electrical supply for both the heating plates and the cooling means.
    Furthermore, even if such a device considerably reduces the air movements in the room compared to conventional air conditioning systems, air movements remain, which can still generate discomfort for people present in the room.
    Finally, systems based on air circulation (heat or cold transfer by convection) always generate relatively large temperature gradients in the room concerned.
    The object of the invention is to overcome these drawbacks by proposing a modular suspended ceiling of the radiating type intended for a room in a building comprising a hydraulic network for supplying hot or cold water, this false ceiling being connected to this network. for emitting or absorbing thermal energy in the room and comprising a plurality of components.
    Thus, the invention relates to a modular radiating false ceiling component, this false ceiling being intended for a room in a building equipped with a hydraulic network for supplying hot or cold water, this component comprising an element made of a material thermally insulating and a heat exchanger arranged adjacent as well as means for connecting said exchanger to said network, so as to receive thermal energy from this network.
    In advantageous embodiments, use is made of one and / or the other of the following arrangements:
    - The component comprises another element made of thermally insulating material, said heat exchanger being disposed between these two elements;
    - the ratio between the thermal resistance of the two elements is greater than 1;
    - Said exchanger comprises a tube directly or indirectly connected to said network, so
    that said tube is traversed by the fluid provided by the network r - said tube forms a curved trajectory, through example a sinusoid or a spiral; - said interchange includes a heat pipe joined at network by contact ; - said interchange also includes at least a
    diffuser means adjacent to said tube or to said heat pipe;
    - Said exchanger comprises a diffuser means connected to said network by contact;
    - The component comprises a heat pipe adjacent to said diffuser means;
    - The diffuser means is a plate made of a metallic or composite material;
    - the heat pipe is in the form of a tube or a plate;
    - the contact between the diffuser means or the heat pipe and the network is made by a clipping system;
    - the component has a generally parallelepiped shape;
    - It includes a facing on the face of the component intended to be visible in the room.
    1 / invention also relates to a modular radiant suspended ceiling for a building comprising a hydraulic network for supplying hot and / or cold water, the ceiling comprising a plurality of components according to the invention.
    Thus, it is understood that a false ceiling made from components of this type does not require a specific supply system, in particular electrical, but uses a hydraulic network already present in the building. This is the case for most tertiary buildings.
    In addition, the heat exchanger which radiates thermal energy from this network, is directly integrated into the component, which avoids the presence of additional elements inside the suspended ceiling volume or protruding on the visible part of the false ceiling. This has many advantages in terms of space, aesthetics, manufacturing and installation.
    This allows the use of all commercially available tiles and therefore gives great freedom of design to architects.
    Furthermore, the maintenance of the false ceiling is very simple since each component can be replaced independently of each other, when a problem arises, for example in the heat exchanger.
    Finally, this false ceiling is of the radiant type, insofar as a very large part of the thermal energy (typically of the order of 80%) is transmitted to the room by radiation, which generates low temperature gradients. in this room and avoids any air movement that can create discomfort.
    It is recalled here that the transmission of heat or cold can take place by conduction, by convection or by radiation.
    Radiation is a mode of energy exchange by emission and absorption of electromagnetic radiation.
    The heat exchange by radiation takes place according to the following process:
    - Emission: there is conversion of the energy supplied by the source into electromagnetic energy
    - Transmission: The transmission of this electromagnetic energy is by propagation of the waves with possible absorption by the medium crossed
    - Reception (absorption): there is conversion of the incident electromagnetic radiation into thermal energy.
    Thus, when the false ceiling warms the room, it is the false ceiling that radiates and the physical bodies of the room (people, objects ...) which absorb the thermal energy emitted by the false ceiling.
    In the case of cooling, it is the physical bodies of the room which radiate and the ceiling which absorbs the thermal energy emitted by these bodies.
    The invention will be better understood and other objects, advantages and characteristics thereof will appear more clearly on reading the description which follows and which is given with reference to the appended drawings in which:

    FIG. 5 includes FIGS. 5A and 5B which are perspective views of an alternative embodiment of the false ceiling component illustrated in FIG. 4, FIG. 5B being a partially cutaway view of FIG. 5A.
    Figure 6 is a sectional view of two components according to the invention, positioned adj acently.
    Figure 7 includes Figures 7A and 7B (Figure 7A being a perspective view and Figure 7B a partial sectional view of Figure 7A) and shows a variant of the embodiment of the exchanger according to Figure 1 .
    The elements common to the different figures will be designated by the same references.
    Reference is first made to FIG. 1 which illustrates a false ceiling component having the form of a slab 1 of parallelepiped shape which has been cut into two parts 10 and 11 in order to be able to insert a heat exchanger 2 there .
    In practice, the upper part 11 of the slab is machined to define a cavity corresponding to the size of the exchanger.
    This slab 1 can be a standard slab, already available on the market. It can in particular be made of expanded polystyrene, plaster, mineral fiber, glass wool or even rock wool for example.
    Generally, this slab is made of a thermally insulating material.
    Throughout the description, it is understood that a thermally insulating material is a material whose thermal conductivity is less than 1.5.
    The upper part 11 of the slab is shown in dotted lines to better illustrate the exchanger 2.
    When the slab is placed in a room, the face 110 of the upper part 11 is visible from the part, while the lower part 10 of the slab is itself facing the plenum.
    This upper part 11 may have a facing, of any kind, not illustrated in the figures or even constitute this facing.
    The only constraint as to the characteristics of this slab is that they allow the slab to be cut into two parts.
    In general, the thicknesses of these two parts are chosen so that the exchanger is as close as possible to the volume of the part to be heated or cooled.
    However, the invention is not limited to this embodiment. It suffices that the false ceiling component comprises a heat exchanger and a first element made of thermally insulating material arranged adjacent to one another. In practice, the insulating element will be placed on the side of the plenum to avoid loss of energy therein, while the other face of the exchanger intended to be turned towards the part may be covered by a second element in a less insulating material than that forming the first element, to favor the transfer of energy in the room.
    Preferably, the ratio between the thermal resistance of the first element and that of the second element is greater than 1.
    The exchanger 2 is, in this embodiment, composed of two elements: a tube 20 and a diffuser means 21.
    The tube 20 forms a sinusoid which extends over substantially the entire surface of the upper face 100 of the lower part 10 of the slab.
    It thus comprises a series of straight parts 203, a first series of curved sections 204 and a second series of curved sections 205.
    Each curved section 204 of the first series connects a first end of a straight section 203 to a first end of another straight section 203 adj acent.
    Each curved section 205 of the second series connects a second end, opposite the first, of a straight section 203 to a second end, opposite to the first, of a straight section 203 adj acent.
    The first and last straight part 203 are extended by a straight section 205, 206 which forms a non-zero angle with the corresponding right part 203. In practice, each straight section 205, 206 is substantially perpendicular to the straight part which it extends and its length is sufficient to cross the lower part 10 of the slab and thus open into the plenum.
    This tube 20 is open at each of the ends 200 and 201 of the straight sections 205, 206, by which the tube 20 is connected to the hydraulic supply network of the building in which the false ceiling is installed.
    The connection between the tube and the hydraulic network can be carried out by means of conventional flexible connections (not illustrated in the figure).
    This tube can be made of polyethylene-based material.
    The invention is not limited to this shape for the tube and it could be shaped differently, for example in the shape of a U or a Z.
    The diffuser means 21 here takes the form of a plate made of a metallic material.
    This plate covers a large area of the upper face 100 of the lower part 10 of the slab, typically between 50 and 100% and it is located between this upper face 100 and the tube 20.
    Generally, this plate is made of a material having a thermal conductivity greater than 10 W / m-kelvin. It can in particular be composed of aluminum or copper when it is made of metal. It can also be formed from an organic material, such as graphite, or also from a composite material comprising a polymer as well as a material whose conductivity is greater than 10 W / m-Kelvin. One can in particular consider a polymer loaded with graphite and then complexed with a metal or a metal alloy.
    This diffusing means 21 makes it possible to distribute the thermal energy provided by the tube 20 thanks to the hydraulic network to which it is connected, and this, over the entire surface of the lower part 10 of the slab 1.
    The plate has transverse grooves 210 into which the straight parts 203 of the tube 20 are inserted.
    The presence of these grooves makes it possible to block the tube relative to the diffusing means and to increase their contact surface.
    Thus, the combination of the tube 20 and the diffuser means 21 ensures a uniform temperature of the slab 1, and therefore improves the supply or absorption of energy by radiation in the room, when the slab 1 is in use.
    Indeed, the hydraulic network can be used to provide hot or cold water and thus heat or cool the room equipped with the false ceiling according to the invention.
    Figures 2A and 2B illustrate an alternative embodiment of Figure 1 in which the exchanger always consists of a tube and a diffuser, the tube being wound on itself (snail-shaped).
    In this example, the slab la in which the exchanger is inserted comprises a lower part 10a which is a facing and an upper part 11a made of an insulating material.
    The facing can also be made of an insulating material. It preferably has a thermal resistance lower than that of the upper part 11a.
    This slab can be a commercial slab, cut in half to remove the facing. The upper part is then machined to define a cavity corresponding to the shape of the heat exchanger 2a. It can also be made up of two independent elements (facing and insulating material element) connected to each other after insertion of the exchanger.
    The exchanger comprises a tube 20a wound on itself and extending substantially in one plane. The shape of the tube appears more clearly in FIG. 2A which shows the upper part of the slab with (in transparency) the tube 20a.
    Insofar as it is designed to cover a large area of the lower face 110a of the upper part 11a of the slab, it is not necessary for the exchanger 2a to comprise a diffuser.
    Indeed, in this case, the tube also plays the role of a diffuser.
    The tube 20a is open at each of its ends
    200a and
    201a. They are located in a plane different from that in which the wound part of the tube extends, to which they are connected by a straight section 202a and 203a.
    These two ends thus open to the outside of the slab 1a so that they can be connected to the network.
    Once the exchanger 2a has been inserted into the upper part 11a of the slab, the facing 10a is fixed against the lower face 110a of the upper part 11a of the slab.
    This facing 10a will be visible from the room, after installation of the slab, while the upper part 11a will face the plenum.
    Reference is now made to FIGS. 3A and 3B which illustrate a second embodiment of a false ceiling component according to the invention.
    This component is again in the form of a slab 3 of parallelepiped shape which can be a standard slab in which a heat exchanger 4 has been inserted, after cutting the slab into an upper part and a lower part.
    FIG. 3A illustrates the upper part 31 of the slab 3, the upper face 310 of which faces the false ceiling volume, when the slab is installed, and the lower face 311 of which faces the lower part of the slab (not illustrated in the figures) and which is visible from the room.
    The thickness of the lower part of the slab is preferably less than that of the upper part so that its thermal resistance is also less than that of the upper part, facing the plenum.
    The lower part may also consist of a facing disposed against the exchanger 4.
    Here again, the exchanger 4 is composed of two elements: a diffuser means 40 and a heat pipe 41.
    The heat pipe 41 is here positioned between the lower face 311 of the upper part 31 of the slab 3 and the diffuser means 40.
    The heat pipe 41 here consists of a tube having the general shape of a sinusoid and which is closed at its two ends 410 and 411. This tube is made of a metal, for example aluminum or copper, or a metal alloy . It is filled with a fluid which changes phase as a function of temperature and pressure. The pressure inside the tube is low to favor phase changes at a relatively low temperature.
    The diffuser means 40 is composed of two parts: a first part 400 having substantially the shape of a plate parallel to the lower face 311 and a second part 401 extending substantially perpendicular to the first part by extending it at one end.
    The first part 400 covers a large area of the surface of the face 311, typically between 50 and 100%.
    It has grooves 410 into which the straight parts of the heat pipe are inserted so as to lock it in position and increase the contact surface.
    The second part 401 has a height H greater than the thickness e of the upper part 31 of the slab 3. It is extended, on the side opposite to the plate 400, by a clipping means 402 on a tube 5 of the hydraulic network of the building.
    Thus, in this embodiment, the exchanger 4 operates in the following manner: the connection between the heat exchanger 4 and the hydraulic network 5 is carried out by means of the diffuser means 40 which is
    connected to this network thanks thanks to clipping 402 and to the second part 401. The diffusing medium transmits so 1'énergie thermal at the heat pipe 41 and broadcasts also 1'énergie produced by the heat pipe on all the surface of slab 3. The invented I am not not limited to fashion of
    embodiment illustrated in FIG. 3B. In particular, the heat pipe could be in the form of a sealed plate and defining a cavity in which are formed grooves for the circulation of a phase change fluid.
    This fluid can be a gas or a liquid, typically water or acetone.
    Furthermore, in this embodiment, the heat pipe could also be omitted, the exchanger then comprising only one diffuser means clipped onto the hydraulic supply network.
    Different means of clipping can be envisaged. They can thus be in the form of a piece independent of the diffusing means or, on the contrary, be integrated into the diffusing means which is then suitably shaped.
    Furthermore, the clipping means can be located on the periphery of the slab or even in the central part thereof.
    Reference is now made to FIGS. 4A and 4B which illustrate a third embodiment of a modular false ceiling component according to the invention.
    This component is in the form of a slab 6 of parallelepiped shape which can be a standard slab. After cutting the slab into an upper part 61 and a lower part 60, a heat exchanger 7 was inserted between these two parts.
    FIG. 4 therefore illustrates the lower part 60 (for example a facing) of the slab 6, the upper face 600 of which faces the upper part of the slab which is itself turned towards the volume of the false ceiling.
    As before, the thermal resistance of the lower part 60 is lower than that of the upper part 61.
    Here again, the exchanger 7 is composed of two elements: a diffuser means 70 and a heat pipe 71.
    This heat pipe is positioned between the upper face 600 of the lower part 60 of the slab 6 and the diffuser means 70.
    The diffuser means 70 is composed of a plate parallel to the upper face 600 of the lower part 60 of the slab which covers a large part of the surface of the face 600, typically between 50 and 100%.
    The heat pipe 71 consists of a tube having the general shape of a sinusoid and which is closed at its two ends 710 and 711. This tube is made of a metal or a metal alloy, for example an aluminum alloy. It is filled with a fluid which changes phase as a function of temperature and pressure.
    FIG. 4B shows that the heat pipe 71 has a flat part which is positioned on the diffuser means 70. This flat part comprises a series of straight parts 714, a first series of curved sections 715 and a second series of curved sections 716, these sections curves connecting the straight parts together. It is extended by a branch 712 substantially perpendicular to the flat part and which is connected to a tube 5 of the hydraulic system of the building, by a clipping means 713. This branch 712 is located above the upper part 61.
    As before, the diffuser 70 has grooves in which the straight parts 714 of the heat pipe are inserted so as to lock it in position and increase the contact surface.
    In this embodiment, the exchanger 7 operates in the following manner: the connection between the exchanger and the hydraulic network is carried out by means of the heat pipe 71 which is connected to this network by means of the branch 712 and by means of clipping 713.
    The heat pipe thus receives energy from the hydraulic network, which leads it to produce energy itself which is then diffused over the entire surface of the slab thanks to the diffusing means 70.
    The invention is not limited to the embodiment illustrated in FIG. 4. In particular, in an alternative embodiment, the heat pipe could be in the form of a plate clipped onto a tube of the hydraulic network of the building in which the false ceiling according to the invention is installed.
    This variant is illustrated in Figure 5.
    In this variant, the false ceiling component comprises a slab 6a with a lower part 60a forming a facing and an upper part 61a made of an insulating material.
    As explained above with regard to FIGS. 2A and 2B, it may be a commercial slab cut in two or two independent elements (element made of insulating material and facing) connected to each other after insertion of the exchanger.
    As explained above, the thermal resistance of the upper part 61a of the slab intended to face the plenum is greater than that of the lower part 60a.
    In FIG. 5B, the upper part of the slab is not illustrated so that the exchanger is better visible.
    The exchanger 7a here consists of a heat pipe which comprises a series of six plates 71a arranged parallel to each other.
    Each of these plates has an L shape, with a first (long) branch 710a disposed between the lower and upper parts 60a and 61a of the component and a second (short) branch 711a, substantially perpendicular to the first, and intended to be clipped on a tube 5 of the hydraulic network by a clipping means 712a. The branch 711a is therefore longer than the thickness of the upper part 61a.
    In this alternative embodiment, the presence of a diffuser is not necessary, the heat pipe 7a also playing the role of a diffuser.
    FIG. 6 illustrates, in section view, two components 9 of false ceilings according to the invention, of the type illustrated in FIG. 5.
    In this exemplary embodiment, the exchanger is limited to a heat pipe 90 and comprises a first part 900 in the form of a plate extending by a second part 901 projecting relative to this plate. This second part is extended by clipping means 902 on a tube 5 of the hydraulic network.
    In this exemplary embodiment of the slabs 9, each slab is cut at a bevel, so that the plate 900 extends in an inclined manner relative to the upper 910 or lower 911 face of the slab
    3.
    This improves the operation of the heat pipe by promoting the phase change of the fluid present inside the heat pipe.
    FIG. 6 thus shows that tiles placed adjacent to the modular suspended ceiling can be clipped onto the same tube of the hydraulic network. This simplifies the network of tubes.
    It may be noted that FIG. 6 could also illustrate an exchanger composed of a diffuser in the form of a plate comprising a flat part and an angled part to allow the plate to be clipped onto the tube 5.
    Reference is now made to FIGS. 7A and 7B which illustrate an alternative embodiment of the exchanger 2 illustrated in FIG. 1.
    In this alternative embodiment, the exchanger 8 is composed of three elements: a tube 80 and two diffusing means 81 and 82. The diffusing means 81 is turned towards the plenum when the exchanger 8 is inserted into the component.
    Again, the tube 80 forms a sinusoid and it is open at each of its ends 800 and 801, by which the tube 80 is connected to the hydraulic network, by means of conventional flexible connections.
    The two diffusing means 81 and 82 are in the form of a plate made of a material having a thermal conductivity for example greater than 10 W / m-kelvin.
    The plate 82 is planar while the plate 81 has grooves 810 into which the straight parts 804 of the tube 80 are inserted.
    In another variant, the two plates could have opposite grooves for accommodating the straight parts of the tube.
    In general, the component according to the invention extends substantially in one plane.
    In an exemplary embodiment of a component according to the invention:
    - the element intended to be turned towards the plenum can be made of rock wool and have a thickness of 40 mm
    1.2 m 2 .K / W) (thermal resistance
    - the facing can be made of BA 13 plaster and have a thickness of 12.5 mm (thermal resistance = 0.04 m 2 .K / W)
    It is understood that a false ceiling can be made from a plurality of components according to the invention connected to the building's hydraulic network.
    These components are conventionally connected to each other in series or in parallel.
    Preferably, these connections are made by means which can be assembled and disassembled easily and in particular without tools.
    As is obvious and as also follows from the above, the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all variants and in particular those where the false ceiling component is not in the form of a slab of parallelepiped shape but in any form, and where the facing of the false ceiling or the element thermal insulation of the plenum is not present on the components but is common to several components.
