Definitions
- the present invention relates to a modular island system for heating, cooling and ventilating buildings by radiation and thermal convection as well as for the acoustic treatment of premises.
- Ceiling diffusers are known in the form of grids which blow the treated air (heated or cooled air and ventilation air) towards the room at a determined angle.
- Some of them blow air at a determined angle (for example 45 °) relative to the ceiling towards the room so as to be suitable for heating and cooling, but the effectiveness of the diffusion is then not optimal on none of the 2 modes, the general comfort is thus very approximate.
- Perforated ceilings or modules which use a perforation to blow the treated air vertically towards the room at very low speed.
- This technology is suitable in cooling mode but is very inefficient in cooling mode. heater.
- hot air less dense than the ambient air, needs to be blown at a certain speed so as to benefit from sufficient kinetic energy to reach the floor of the room and therefore to avoid stratification phenomena.
- Ceiling cassettes are also known, frequently installed especially in office spaces or shops, the latter are equipped at their periphery with motorized diffusion fins which allow the angle of the air blowing to the room to be adjusted.
- Their drawback lies in the fact that it is up to the user to adjust the diffusion angle daily depending on the temperature of the blown air, which in practice is very difficult to achieve.
- radiant panels use thermal radiation to diffuse 100% of the useful thermal power.
- These can be in the form of modules, some with the possibility of treating the acoustics of the room via a perforated plate permeable to thermal radiation in the lower part of the module and an acoustic insulation placed inside the module.
- This process using only thermal radiation as a diffusion vector has a very limited cooling power due to the risk of reaching the dew point on the surface of the panel and therefore the risk of condensation forming.
- This device unlike the previously mentioned methods, uses both convection and radiation to diffuse thermal power. Very comfortable in heating mode as in cooling mode thanks to its parietal air diffusion (along the walls of the room) it avoids the phenomena of drafts and allows to benefit from a very good homogeneity of temperatures within the volume occupancy of the premises. However, it needs to be installed over the entire ceiling surface of the room served, thus allowing reduced flexibility in buildings where the rooms may have to be often redefined via changes in partitioning such as, for example, offices.
- US 2020/003450 (SURMINSKI DAVID MARK [CA] and AL) describes a laminar flow diffuser with integrated lighting having a frame for supporting an air plenum and a lower housing.
- the air plenum receives conditioned air from a conditioned air source.
- the lower case is attached to the bottom of the plenum.
- An opening plate damper installed below the upper plenum regulates airflow from the plenum through the laminar flow diffuser.
- a transparent or translucent perforated diffuser face forms the outlet from the lower housing to the room below. LED strips are positioned around the inner periphery of the lower case.
- a perforated reflector panel is positioned below the aperture plate damper and above the LED strips to diffuse light from the LED strips through the perforated diffuser face.
- JP H0268445 (A) (DIESEL KIKI CO) (DIESEL KIKI CO) (DIESEL KIKI CO), it is intended to eliminate a drive power supply, reduce the number of parts and enable prevention of an engine drive noise to be made by a process in which a thermosensitive part is formed by a hydrogen occlusion alloy, an actuator is actuated by a hydrogen pressure. When a temperature of the air blown inside an air blast duct is high, the hydrogen is discharged from a hydrogen occlusion alloy, so that a pressure of hydrogen inside a pipe and an actuator is increased.
- the actuator consisting of bellows is extended due to this increase of hydrogen pressure, a rod is moved upward and each of the flaps is set to point downward.
- the hydrogen is absorbed into the hydrogen occlusion alloy, so that the hydraulic pressure inside the pipe or of the actuator decreases and so the actuator is retracted and the rod is moved down.
- Each of the shutters is arranged upwards. At a temperature intermediate between a high temperature and a low temperature, an angle of each of the flaps is linearly controlled in response to a hydrogen absorption and discharge characteristic of the hydrogen occlusion alloy.
- US 3,937,133 A (BERTIN MANNIE et AL) describes an outlet for air conditioning having a plurality of interconnected modules establishing its side walls which support a closed bottom and through which the outlet is connected to a mounting frame.
- Each module has a support frame made up of upper and lower side members and end members, each a length of one extrusion providing an outer wall and an inwardly disposed wall.
- Means are provided for interconnecting the frames to each other vertically or laterally in the same plane or at right angles so as to provide airtight joints.

- Another object of the invention is to provide a modular island intended for heating, cooling and ventilating a room by radiation and thermal convection, said modular island being able to be suspended from the ceiling of a room, said modular island comprising : a peripheral frame (1) provided with at least one line of attachment of a diffusion element such as a stretched canvas (8) located in its lower part opposite the ceiling; on one or more of its faces, said peripheral frame (1) comprises an air blowing slot (2) towards the room; a diffusion element such as a stretched canvas (8), hooked onto the hanging line of the peripheral frame, visible from the room and forming the horizontal underside of said modular island; a cover (19) forming the upper face of the modular island facing the ceiling; an air blast connection (4) fixed to the cover (18) of the island modular and allowing the injection of treated air into the interior volume of the modular island; a channel of articulated deflectors (10, 11) formed by an upper articulated deflector (11) and a lower articulated deflector (10), fixed to the peripheral frame (1) at the level of the air blowing slot
- thermostatic actuation means (13) making it possible to actuate said channel of articulated deflectors (10, 11) by means of an actuating means of the deflectors such as an actuating rod (14) and giving the channel a blowing angle depending on the temperature of the treated air injected into the modular island, said thermostatic actuating means (13) comprising a piston whose output stroke depends on the air temperature in which said actuating means thermostatic (13) is submerged; a return spring (15) making it possible to exert a force opposite to the stroke of the piston of said thermostatic actuating means (13) and thus to return it to its minimum stroke when cold air is blown into the island modular, and where, said channel of articulated deflectors (10, 11) comprises an articulated means for maintaining parallelism (12) positioned in said channel and connecting the upper and lower articulated deflectors (11 and 10) to the points of articul
- the invention as described has in particular the advantage of allowing thermal diffusion towards the room served both by radiation and by convection. Indeed, under the effect of the flow of treated air (hot or cold) injected into the modular island, the diffusing surface (8) (ideally a stretched canvas) will heat up or cool down so as to generate thermal radiation towards the room. In addition, the treated air injected into the Modular Pilot, after having given up part of its thermal energy to the diffusing surface, will come out through the blowing slot (s) (2) thus causing diffusion by thermal convection towards the room (room to be treated).
- the diffusing surface ideally a stretched canvas
- thermostatic actuation means (13) for example a thermostatic cylinder
- this solution allows an orientation of the air flow blown through the slot (2) ( convective power) depending on the temperature of the treated air flow, so when cold air is injected into the modular island (in cooling mode) it will be blown parallel to the ceiling, ideally at 0 °, (minimum stroke of the thermostatic actuating means (13)); Conversely, when hot air is injected into the modular island (in heating mode), it will be blown towards the room (ideally at 45 °) so as to eliminate stratification phenomena.
- thermostatic actuation means (13) for example a thermostatic cylinder
- the geometry used based on an articulation allows a variation of the section of the blowing slot (2), thus in cooling mode the deflectors (or fins) in horizontal position generate the maximum section of the slot (2) and therefore low air speeds; Conversely in heating mode, the section of the slot (2) is reduced to the maximum, thus increasing the speed of the blown air and therefore the range of the air flow.
- the system according to the invention makes it possible to act on the air blowing slot (2) and therefore on the articulated deflector channel (10, 11) so as to direct its flow and vary its section.
- a modular island element for heating and / or cooling and ventilation of a building room the modular island element once suspended from said ceiling by means of hangers (7) comprises: a connection nozzle (3) allowing connection to an air suction duct of so as to route the ambient air from the room to an air conditioning unit, for example a fan vector or an air handling unit; the air sucked in from the room, ideally passing through a filter (6) via, for example, a sealed filter-holder suction box (18) fixed to the upper cover (19) of the modular island (see Figure 5); once heated or cooled and optionally mixed with fresh ventilation air (if the modular island is also connected to the room ventilation system), the treated air is injected inside the volume of the island by the intermediary of a branch connection of the blowing duct (4); depending on the temperature of the treated air injected into the island, the thermostatic cylinder (13) (or any other material allowing the same use to be fulfilled) deploys a stroke of its piston proportional to the temperature of the injected air (see
- a return spring (15) makes it possible to oppose a force to the stroke of the thermostatic cylinder (13) so as to bring it back to its minimum stroke when cold air is blown into the island;
- the thermostatic cylinder (13) actuates a means for actuating the air blowing deflectors (14), such as for example an actuating rod (or linkage), connected to the channel of articulated deflectors (10, 11), subjecting the deflectors (10, 11) at an angle depending on the temperature of the treated air injected into the modular island; whatever their angle, the articulated deflectors, ideally 2 deflectors with one upper and one lower (10 and 11), fixed to the peripheral frame (1) remain parallel thanks to the articulated means of maintaining the parallelism of the deflectors such as for example an articulated rod (12) connecting them together, in fact the points of articulation between the deflectors (ideally 2 deflectors 10 and 11), the peripheral frame (1) and the articulated means for maintaining the
