[0037] The aeraulic device 1 can also be provided with a sound-absorbing or thermo-acoustic insulation material layer 8 arranged internally (as in the example in FIG. 4) or externally to the case body 2.

[0038] With reference only to FIGS. 1 to 3, the radiant ceiling thermal system 10 subject of the present invention for heating and cooling an internal room 100 is described below in several preferred embodiments.

[0039] The radiant ceiling thermal system 10 comprises in its general embodiment: [0040] a radiant surface or false ceiling 14 formed by one or more of radiant panels 12 connectable to each other, said radiant panels being provided with pipeline 15 suitable for transporting a heat carrier fluid; [0041] an upper volume or plenum 20 comprised between the false ceiling 14 and the surface of the upper slab 102 of said internal room 100.

[0042] Said false ceiling 14, formed by one or more interconnected radiant panels 12, is provided with at least two openings 18 suitable for placing in inlet and outlet fluid connection said internal room 100 with said upper volume or plenum 20.

[0043] Said radiant ceiling thermal system 10 is provided of the innovative feature of comprising at least one aeraulic device 1, 1, above described, arranged above said false ceiling 14 between said internal room 100 and said upper volume or plenum 20, said aeraulic device 1, 1 being suitable for circulating air in such a manner as to mixing said circulating internal air through said openings 18 and prevent its stratification at different temperatures.

[0044] The false ceiling 14 generally has an exposed surface in direct contact with the internal room 100 and can have a smooth or micro-perforated finish and can be made of metal, plasterboard, or other compatible building materials.

[0045] With particular reference to the closed embodiment form of FIG. 1, where the ceiling 14 is configured to cover the entire surface of the upper slab 102, the at least two openings 18 are formed directly into two or more radiant panels 12, in such a way as to place in fluid connection the internal room 100 and the upper volume or plenum 20.

[0046] In other possible further variant embodiments said openings 18 can be defined by the absence or by the array interruption of one or more elements or radiant panels 12 to form the ceiling 14.

[0047] Said at least an aeraulic device 1 for air circulation can be arranged with the inlet opening 3 or outlet opening 4 placed at said at least two openings 18 and configured in such a way as to move the inlet and outlet internal air into the upper volume or plenum 20.

[0048] Said radiant ceiling thermal system 10 can be provided with an external support structure 16 suitable for attaching said panels to the load-bearing surfaces of the internal room 100 or upper slab 102 and configured in such a way as to define the vertical height of said volume or plenum 20.

[0049] Again with reference to FIG. 1, the support structure 16 of the false ceiling 14 can generally be provided by the rigid frame of radiant panels 12 interconnected to each other and to the surface of the upper floor slab 102 or to the walls of the internal room by means of known means of attachment not shown, such as brackets joints screws etc.

[0050] Said support structure 16 can also be independent of the radiant panels 12 and stabilized to the load-bearing structure of the internal room 100 prior to the arrangement and connection of the same radiant panels 102 to form the false ceiling 14.

[0051] Again with reference to the embodiment form of FIG. 1 and also FIG. 3, the radiant ceiling thermal system 10 can comprises further more aeraulic devices 1 advantageously arranged in pairs, with an aeraulic device 1 configured for the inlet and an aeraulic device 1 configured for the outlet of the internal air flow in the upper volume 20.

[0052] With special reference to FIG. 3, in radiant ceiling thermal system s 10 with very large radiant surfaces, deferral aeraulic devices 1 can be provided and suitable for maintaining constant air flow within the upper volume or plenum 20.

[0053] For a very extensive radiant surface 14 additional return fans 30 can be arranged configured to maintain a constant and uniform flow of circulating internal air within the upper volume 5 or plenum 20.

[0054] With reference again to FIGS. 1 and 3, it will be clear to a person skilled in the art, how the inlet and outlet openings 3, 4 and the direction of rotation of the fans 30 of the aeraulic devices 1 can be reversed depending on whether the aeraulic device 10 is configured to feed air into the upper volume or plenum 20 by extracting it from the internal room 100, or to extract air from the upper volume or plenum 20 to feed it into the internal room.

[0055] In an alternative open type embodiment, with special reference to FIG. 2, the false ceiling 14 can be smaller in size than the area of the upper slab 102 and be configured to cover only a portion thereof, in this case the at least two openings 18 are defined by the surface portion of the upper slab 102 not covered by the false ceiling 14. These at least two openings 18 are formed directly into two or more radiant panels 12 in such a way as to place the internal room 100 and the upper volume or plenum 20 in fluid connection.

[0056] Again with reference to the embodiment of FIG. 2, the false ceiling 14, formed by one or more radiant panels 20, typically comprises brackets or tie rods 16 suitable for keeping the false ceiling 14 suspended from the surface of the upper slab 102.

[0057] Said at least an aeraulic device 1 suitable for air circulation can be arranged on the top of the false ceiling 14 and stabilized directly on the radiant panels 12, said aeraulic device 1 being configured in such a way as to move the incoming and outcoming air into the upper volume or plenum 20, even if not integrally bounded by the false ceiling 14.

[0058] The fan 30 arranged within the aeraulic device 1 can be any type of fan, or blower, such as a radial type impeller fan, an axial bladed fan, or an axial vaneless fan.

[0059] If the ceiling 14 surface is very wide, additional transmission fans 30 can be provided, configured to keep the internal air flow constantly circulating within the internal volume or plenum 20.

[0060] In the embodiments of FIGS. 1 and 2, the false ceiling 14 and radiant panels 12 can also be devoid of a thermal insulating layer on the face opposite that facing the internal 100 and can instead advantageously comprise an acoustic insulation layer or multilayer insulation with acoustic insulating features.

[0061] In a further embodiment of the radiant system 10, with particular reference to FIG. 3, said upper volume or plenum 20 can be formed and integrated directly within the structure of the connected radiant panels 12 and arranged between the supporting surface of the pipeline 15 of the heat carrier fluid and a thermal insulating layer 42 suitable for defining a thermal insulating surface 44 in cooperation with a plurality of radiant panels 12.

[0062] The radiant panel 12 can advantageously comprises a support structure 16 or frame configured to maintain the pipeline 15 support surface at a distal position from the thermal insulating layer 42 in such a way that an upper volume or plenum 20 arranged between the false ceiling 14 and the thermal insulating surface 44 can be realized in cooperation with a plurality of radiant panels 12.

[0063] Said support structure 16 can also be advantageously fixed to the load-bearing structure of the internal room 100.

[0064] Still with reference to FIG. 3, said aeraulic devices 1, 1 for air circulation can be arranged with the inlet and outlet openings 3, 4, placed therein the same at least two openings 18, only formed on the false ceiling 14 and not on the thermal insulating surface 44, or arranged within the upper volume or plenum 20 and configured in such a way as to move the inlet and outlet air into the upper volume or plenum 20.

[0065] In the latest embodiment also, said fans 30 of the aeraulic devices 1, 1 can be radial fans configured to move the air flow by changing its direction by 90 but can also comprise any type of fan suitable for moving the air such as axial blade fans or axial vaneless fans.

[0066] With reference to all the embodiments, said aeraulic devices 1, 1 can be fixed directly to the false ceiling 14 on the radiant panels 12, to the support structure 16 or to the surface of the upper slab 102, or they can be fixed by an auxiliary support frame (not shown).

[0067] The radiant panels 14 can be advantageously shaped in such a way as to allow the opening 18 to be made for the passage of air flow and for anchoring the support frame of the aeraulic devices 1, 1.

[0068] The pipeline 15 of the thermal carrier fluid of the radiant panels 12 can also be shaped and arranged in such a way as to allow the opening 18 for the passage of air flow to be obtained subsequently, in order to have a radiant panel 12 having a single shape suitable to defining the false ceiling 14 once installed.

[0069] Said auxiliary support frame (not shown) of the aeraulic devices 1, 1 can also be advantageously orientable in such a way as to direct the airflow of the aeraulic devices 1, so as to define preferential flows within the upper volume or plenum 20.

[0070] The radiant ceiling thermal system 10 subject of the present invention can also comprise a fan control system 30 of the aeraulic devices 1 controlled by a logic unit in such a way as to operate continuously or intermittently. Said control system can also comprise temperature sensors arranged in the whole room 10 and upper volume 20 in such a manner as to operate the fans 30 for example when the logic unit detects a temperature differential above a certain limit.

[0071] From the description of the aeraulic device 1 and the radiant ceiling thermal system 10 subject of the present invention it is possible understanding the operation described below.

[0072] With reference starting to FIG. 4, the aeraulic device 1 subject of the present invention has, in a simplified embodiment, a case body with an inlet and outlet 3, 4 configured for inlet and outlet of the airflow generated by the fan 30.

[0073] Said device is arranged above the radiant ceiling 14, as in the examples of FIGS. 1 and 2, and it is configured to drawing in and feeding air into the upper volume or plenum 20 and then feeding it back into the internal room 100.

[0074] The aeraulic device 1 is arranged at or near each opening 18 and for each aeraulic device 1 configured to feed air into the upper volume or plenum 20 from the internal room 100, an additional aeraulic device 1 configured to take air from the upper volume or plenum 20 and feed it back into the internal room 100 can be coupled for greater efficiency.

[0075] It is evident how the inlet and outlet openings 3 and 4 are defined by the direction of the airflow movement given by fan 30 and can be reversed.

[0076] The fan 30 inside the case body can be configured to move the airflow in either direction.

[0077] In a preferred embodiment of FIG. 1, two aeraulic devices 1 are arranged at openings 18 in the ceiling 14. The aeraulic device 1 of extracting air from the internal room 100 is arranged with the inlet opening 3 connected to an opening 18 while the outlet opening 4 is in fluid connection with the upper volume or plenum 20. While the aeraulic device 1 of reintroducing air into the internal room is configured with the inlet opening 3 in fluid connection with the upper volume or plenum 20 and the outlet opening 4 connected with the other opening 18.

[0078] The optional presence of a filter element collects dust and particles present in the air while the presence of an air sanitizing device 7 or system releases sanitizing and bactericidal substances contained in a reservoir into the airflow, so as to purify and sanitize the mixing airflow.

[0079] The presence of an additional sound-absorbing layer 8 in the case body 2 makes the device quieter by eliminating noise and vibration due to the fan 30 and its electric motor.

[0080] Again with reference to FIG. 4, the deflection and conveying means 5 of the flow such as vanes, conveyors or slits arranged at the inlet and outlet openings 3, 4, allow preferential orientation of the airflow input to the upper volume or plenum 20, the calibration and adjustment of the flow rate, but also allow improved airflow capture from the upper volume or plenum 20 by improving the recirculation flow and thus the air mixing between the upper volume or plenum 20 and the internal room 100.

[0081] With initial reference to FIG. 1, in the first embodiment of the radiant ceiling thermal system 10, the hot or cold air that tends to stratify in the upper volume or plenum 20 above the ceiling 14, as shown in the example in FIG. 5, is advantageously mixed with the air from the internal room 100 by means of the fans 30 of the aeraulic device 1, to create a recirculating internal air flow indicated in FIG. 1 by the circuit F of arrows. The fan 30 of at least one aeraulic device 1 is configured to draw air from the inlet opening 3 in the internal room 100 through an opening 18 and feed it into the upper volume or plenum 20 in a manner that mixes with the stratified air and then is fed back into the internal room 100 through an additional aeraulic device 1.

[0082] Also in the embodiment of FIG. 2, the stratified air above the false ceiling 14 is mixed into the internal room 100 by the recirculating internal air flow generated by the axial fan 30 of the aeraulic device 1 according to the circuit F of the arrows in FIG. 2.

[0083] With reference to all embodiments, the mixing of internal air generated by the at least one aeraulic device 1, through the openings 18, is capable to equalize the temperature T.sub.A [ C.] of the internal room 100 and limit energy consumption by going to use the energy stored in the air stratified in the upper volume or plenum 20 above the false ceiling 20.

[0084] The technical solution subject of the present invention is also further advantageous because it allows the use of simpler and lighter radiant panels 12 without the need for an insulating layer on the opposite face to the face facing the internal room 100, or advantageously allows the thermal insulating layer to be replaced by an acoustic insulating layer.

[0085] With particular reference to FIG. 3, in a further alternative embodiment form of the aeraulic device 1 and radiant ceiling thermal system 10 subject of the present invention, the internal volume or plenum 20 can advantageously be realized inside to the plurality of radiant panels 12 forming the ceiling 14, arranged between the exposed surface in contact with the heat carrier fluid pipeline 15 and an insulating layer 42.

[0086] In this particular embodiment, the aeraulic device 1 can have the size and the structure of a traditional radiant panel 12, comprising pipeline 15 and hydraulic connecting means to the other radiant panels 12 in such a way as to be integrated into the structure of the radiant surface or false ceiling 14.

[0087] The aeraulic device 1 can also comprise an insulating layer 42 arranged in contact with or opposite to the part containing the pipeline 15 with the inner volume or plenum between the pipeline and the insulating layer 42, as in the example in FIG. 3.

[0088] This embodiment is advantageously applicable on installations in which the upper volume or plenum 20 has considerable dimensions for which an efficient recirculation flow of internal air would not be achievable.

[0089] In this case, the aeraulic devices 1 convey air drawn from the internal room 100 into the upper volume or plenum 20 arranged between the pipeline 15 of the false ceiling 14 and an insulating layer 42 and then feed it back into the internal room. The recirculation airflow shown in FIG. 3 with circuit F of arrows also allows the stored stratified thermal (or cooling) energy in the upper volume or plenum 20 to be collected.

[0090] This solution, in addition to allowing a uniformity of the temperature T.sub.A [ C.] of the internal room 100, allows energy saving by avoiding mixing of the internal air of rooms in very high ceilings or vaults, also allowing the use of an insulating layer 42 and a less thick insulating surface 44, thus advantageously allowing the addition of, for example, other layers of sound insulation while at the same time maintaining compact radiant panel dimensions 12.

[0091] The management of the speed of the fans 30 of the aeraulic device 1 by means of an electrical or electronic system allows to realize a mixing system that can be manually controlled or automatically operated by a desired operating logic.

[0092] The above operation considerations, carried out by considering the embodiments of the radiant ceiling thermal system 10 in an exemplary starting condition as in FIG. 5, in the case of a traditional radiant system operating in heating mode, will result obviously applicable to a person skilled in the art also considering an exemplary starting condition as in FIG. 6, in the case of a traditional radiant system operating in cooling mode.

[0093] It will also obviously result to the person skilled in the art that in cooling operation mode, the radiant system 10 subject of the present invention also comprises a dehumidifier device for lowering the humidity level of the air in the internal room 100.

[0094] As can be seen from the foregoing are evident the advantages that the aeraulic device 1 and the radiant ceiling thermal system 10 subject of the present invention achieve.

[0095] The aeraulic device and the radiant ceiling thermal system 10 subject of the present invention are particularly advantageous because thanks to the mixing the internal air of a room, it allows the improvement of living comfort and equalizes the temperature of the internal room by avoiding stratification of air at different temperatures and reducing energy consumption.

[0096] Mixing enhances convective motions that are already naturally present, extending them to areas of the radiant ceiling thermal system with high energy potential that would otherwise be less involved. The increase in said motions allows an improvement in the convective heat transfer of the ceiling.

[0097] Further important advantage due to the aeraulic device 1 and radiant ceiling thermal system 10 is to provide the user with a simple, thin radiant panel, without the need for a layer with thermally insulating features or replaceable with an acoustic insulating layer or also having acoustic insulating features.

[0098] A further advantage of the radiant ceiling thermal system is to provide the user with a radiant ceiling thermal system 10 that can also be easily integrated even on pre-existing installations with very high ceilings or vaults.

[0099] Although the invention has been described above with particular reference to several preferred embodiments, given for illustrative and non-limiting purposes, numerous modifications and variations will become apparent to a person skilled in the art in the light of the above description. The present invention is therefore intended to embrace all modifications and variations falling within the scope of the following claims.
