Description

Technical part

The present invention relates to a ceiling or wall radiation system for heating and / or cooling a building space by radiation and convection.

State of the art

The creation and maintenance of a pleasant and healthy atmosphere in the premises of a building, allows commercial or private activities in a pleasant way to exercise throughout the year. In particular, the creation and maintenance of predefined temperature conditions in a room makes it possible to reduce seasonal discomfort and to respond quickly to thermal load changes. The radiant ceiling is the only heating / cooling system that allows for minimal mixing of air and therefore dust. This has a very positive effect on health.

At the end of the nineties, the first administration buildings were equipped with radiant ceilings, first for cooling and then for heating. More recently, this technique has been used in various building types. Because of the price of the installation, other air conditioning techniques are still widely used, although radiant panels are more energy efficient and provide more comfort.

The document DE102009055443 describes a ceiling or wall element comprising a sound absorbing material surrounding the tubes in which a heat transfer fluid circulates.

The document EP2210992 describes a prefabricated thermoactive plate configured to force the transfer of ambient air through a channel to control its temperature by heat exchange with the heat transfer fluid.

The document US2005 / 0040152 describes a thermoactive element for cooling and heating a space having a lamellar structure, which is thermally connected to a tube in which a heat transfer fluid circulates. The cavities created by the lamellar structure are filled with a sound absorbing material, while the extremities of the structure are connected to a metal radiation plate.

The document EP2762787 describes an element for room air conditioning, which consists of a radiating plate made of aluminum and a layer of non-woven phonoabsorbierendem material. The radiant panel is thermally bonded by welding to tubes in which a heat transfer fluid is circulated and transferred into a plurality of aluminum intermediate plates, each intermediate plate being previously welded to a straight section of a tube.

Brief summary of the invention

An object of the present invention is to provide a radiation system for the creation and maintenance of specific temperature conditions in the premises of a building, which is easy to manufacture and install, has a pleasant aesthetics and a competitive price compared to known radiation systems.

A particular concern of the invention is to provide a radiation system for heating or cooling a room with great efficiency and homogeneity.

Another object of the invention is to utilize a radiation system in addition to reducing the propagation of sound waves in the premises.

These objects are achieved according to the invention in particular by a modular radiation system for the ceiling or wall of a building space, the modular radiation element comprising:
a tube, preferably in the form of a meander, which may be connected to a distribution line of a building and / or to a tube of another modular radiating element to allow a heat transfer fluid to circulate inwardly;

A copper plate connected to the tube by means of a weld and having a plurality of through holes for guiding sound waves through the copper plate; and
a trim panel covering the copper plate, the trim panel having through holes (and / or notches) sized to allow sound waves to pass through the trim panel.

This solution has the advantage of improving the heat exchange between the coolant and the surface of the false ceiling or the false wall of a building, partly thanks to the better thermal conductivity between the radiant panel and the pipe and secondly to the cladding panel which supports the suspended ceiling or ceiling form the wrong wall while the Costs for the manufacture and installation of a radiation system are limited.

In fact, the perforations of the cladding panel not only enable the realization of a suspended ceiling or false wall with a room-specific aesthetics, but also a reduction of the sound level by the holes directing the sound waves toward a sound absorbing layer near the ceiling or wall, which makes the solution economically interesting.

According to the invention, the targets in a building space are achieved by a radiant ceiling or wall system by mounting a plurality of these modular radiating elements.

The modular approach can respond efficiently and quickly to the sizing requirements of the system and help to reduce the manufacturing and installation costs of the radiation system.

Example (e) of the embodiment of the invention

The 1 to 4 show a modular radiating element 1 for a radiation system 100 a ceiling or wall used for heating and cooling a building by radiation and by thermal convention.

The modular radiating element 1 includes first a pipe 11 in the form of a meander whose free ends 111, 112 can be connected to a distribution line of the building and / or to a tube of another radiation element, so that the passage of a heat transfer fluid is made possible. The modular radiating element 1 comprises a copper plate 12 that with the said pipe 11 along the wall surface of the tube 11 with the plate 12 connected and configured so that it allows a heat exchange with a suspended ceiling or a false wall of an interior. This plate 12 is perforated (with openings which will be described later.

The modular radiating element 1 further includes a cover plate 14 holding the copper plate 12 covering, leaving the suspended ceiling (generally a metal ceiling) or the wrong wall of a bandage 14 resulting from several of these juxtaposed plates.

The cover plate 14 is generally made of metal and has a substantially flat outer surface and is generally called a "metal cassette". The outer surface of the cladding panel or possibly the entirety of the cladding panels are treated to obtain a pleasing aesthetics and to be suitable for the installation site.

The panel plate 14 is perforated to allow passage of sound waves through the layer so as to ensure attenuation of the noise pollution by means of a sound absorbing layer while ensuring a pleasing aesthetics.

The sound-absorbing layer may be a layer (already present or separately installable) of the ceiling or wall, or may result from the use of a material having phono-absorbing properties for the realization of the ceiling or wall. Advantageously, the modular radiating element comprises 1 Furthermore, a sound-absorbing layer 10 holding the copper plate 12 on the side of the ceiling or the wall covering (or covering), so after mounting the modular radiating element 1 , which are achieved and maintained predefined sound attenuation parameters.

The sound absorption layer 10 can be dimensioned so that it is housed between the curvatures of the meander.

Alternatively, the sound absorption layer 10 be dimensioned so that they not only the copper plate, but also (at least part of) the meander 11 covered (or covered).

Thus, adding to the perforated trim panel allows 14 (or metallic ceiling plate or metal cassette) of an assembly consisting of the copper plate 12 and the pipe (s) 11, which are joined by welding, a thermal and sound-absorbing control function, so that the plate 14 becomes an "activated disk".

The Applicant has surprisingly found that a modular radiating element consisting of a plate 12 made of copper, which is welded to the pipe, allows effective heat exchange between the cooling medium and the suspended ceiling of the premises, while the (surcharge) final price of the radiation system is limited compared to known systems.

In fact, the manufacturers of radiant ceilings are generally reluctant to use copper in their systems, although copper is known for its optimum thermal conductivity because of its high cost compared to other thermally conductive materials such as aluminum. The use of copper in radiation systems is therefore currently excluded from the choice of material for the production of large elements, in particular for the radiation plate.

The Applicant has thus found that, thanks to the high thermal efficiency of the preferred solution resulting from the use of copper for the production of the radiation plate 12 yields, as well as a thermal connection by welding between the plate 12 and the tube 11 a larger perforation of the plate 12 allows. The holes 120 through the perforated plate 12 are thus dimensioned so that they are not just the sound waves to a sound-absorbing layer 10 but also a reduction of the copper content for the production of the perforated copper plate 12 enable.

The holes 120 can be homogeneous or inhomogeneous on the copper plate 12 be dimensioned and distributed, so as to the relationship between the copper cost and the heat transfer capacity between the heat transfer fluid of the modular radiating element 1 and the ambient air of the room and / or the radiating element 1 to optimize related objects.

As in 2 shown, the total area of the through holes 140 the panel 14 smaller than the total area passing through the through holes 120 the copper plate 12 is formed. The holes 140 The cladding panel is primarily intended to transmit sound waves and to ensure a pleasing aesthetic appearance, while the through holes 120 the copper plate mainly serve the copper weight of the radiation plate 12 to reduce. The through holes 140 the cover plate may thus have dimensions (diameter) which are smaller than the dimensions of the through holes 120 the perforated copper plate 12 , Second, the through holes allow 120 in the case of the copper plate 12 , the sound waves through the perforated copper plate 12 to a sound absorbing layer 10 respectively.

Advantageously, the through holes represent 120 (and / or notches) between 0% and 40% of the surface of the perforated copper plate 12 , preferably between 15 and 30%, and more preferably between 20 and 25%, and advantageously on the order of 25%. Furthermore, the perforated copper plate 12 preferably a thickness between 0.1 mm and 2 mm, more preferably between 0.1 mm and 0.4 mm and advantageously a thickness of the order of 0.2 mm.

The through holes 120 The copper plate may take various forms, such as a round, circular, oval, square, rectangular, polygonal shape.

The through holes 120 the copper plate 12 , which are arranged in areas that are different from the welds 20 farther away, may have a larger dimension and / or a greater number per unit area compared to those portions near the welds. Thus, for example, the through holes of the copper plate are unevenly distributed and / or dimensioned, preferably as a function of the distance to the said weld 20 ,

The through holes 120 the copper plate 12 , which are arranged in areas that are close to the entrance of the cooling medium into the pipe 11 can have a smaller dimension and / or a smaller number per unit area compared to the areas of the exit side. The area of the inlet side of the pipe 11 corresponds to the section of the pipe 11 which is first traversed by the cooling medium (hot or cold).

The pipe (the meander 11 ) of the modular radiating element can be processed to improve the heat transfer between the heat transfer fluid and the suspended ceiling of the room, in particular by one or more grooves and / or one or more projections (for example: in the form of ribs) on the inner wall side the heat exchange surface between the wall of the pipe 11 and the heat transfer fluid flowing through is increased.

3 shows an embodiment of the tube (meander 11 ) with a series of grooves 110 , in particular parallel grooves, which form ribs on the surface of the inner wall of the tube to the contact and heat exchange surface between the medium and tube 11 to enlarge.

Advantageously, the groove 110 (and its complementary rib) spiral to turbulence to produce the passage of the heat carrier in the pipe 11 facilitates and improves heat transfer.

To improve the efficiency of heat exchange between the pipe (meander) 11 and the plate 12 of copper (or aluminum), the tube may be made of copper to allow thermal fusion by welding without supplying other matter.

The realization of a radiation system 100 by means of a modular radiation element 1 also facilitates its manufacturing and installation through a modular approach, which helps to make the solution economically competitive. Thus, it is possible to use a ceiling or wall radiation system ( 100 ) to install a building space containing a variety of modular radiating elements 1 includes, as described herein.

The perforated plate 12 made of copper is thermal with the tube with or without internal ribs (meander 11 ) by means of at least one weld 20 resulting from a welding process with no or with material supply (brazing).

Welding provides better resistance between the composite materials (directly or through the starting material), which produces a more efficient thermal bond than that achieved by mechanical assembly techniques or adhesion.

Advantageously, the modular radiating element comprises 1 also an acoustic fleece 13 , which also serves as optional dust retention. This acoustic tile 13 is between the cover plate 14 and the copper plate 12 positioned.

The acoustic fleece 13 is configured to remove the falling dust from the plate 12 holds back, in particular because it is perforated, possibly of the tube 44 and / or the surface of the sound absorption layer 10 , and this under the action of gravity and / or the movements (thermally and / or mechanically forced) of ambient air when the modular radiating element 1 is mounted under a ceiling or on a wall of a building room.

The layer or the tile 13 is in the arrangement between the copper plate or the aluminum 12 and the panel plate 14 positioned.

The modular radiating element 1 includes a mounting structure 15 for mounting and installation of the modular radiating element 1 (please refer 2 ). Advantageously, the mounting structure with fastening means for easy installation of the modular radiating element 1 provided under a ceiling or on a wall of a building room. Advantageously, the attachment structure is provided with attachment means which provide a juxtaposition and attachment of the modular radiating element 1 in addition to other or other identical modular radiating elements 1, so as to form a larger suspended ceiling or false wall.

4 shows a thermal arrangement of the copper plate, including its perforation 12 , with a tube or a meander 11 which has been joined by laser welding and which is the preferred manufacturing method. This welding process makes it easy to produce welds safely, precisely and cost-effectively, covering a large area (straight and curved) of the pipe and the plate, thus improving heat exchange.

To the efficiency of heat exchange between the pipe 11 (Meander) and the copper plate 12 To further improve, the copper tube may be internally ribbed for optimal heat exchange with the plate 12 to enable. In order for the thermal connection by welding to be as effective as possible, laser welding is preferably used. In this case, it is possible to use a copper pipe with or without fins having an inner diameter between 4 mm and 25 mm, preferably between 6 and 18 mm. Advantageously, the wall thickness of this copper tube 11 between 0.15 mm and 1.5 mm, preferably between 0.2 and 0.7 mm.

As expected, the modular approach of the modular radiating element allows 1 according to the invention, to react efficiently and quickly to the sizing requirements of the system, in particular the ceiling or wall surfaces, for the radiation system 100 available, which helps to reduce the installation costs of the radiation system.

The modular approach also allows a reduction in the manufacturing cost of the radiation system 100 ,

The modular radiating element 1 can by welding a copper plate 12 to the pipe (meander 11 ) are joined together to pass a heat transfer fluid within the tube.

The welding process is preferably carried out by laser welding. Alternatively, the weld (welding process) by soldering with Tin or MIG (metal inert gas) and / or TIG (tungsten inert gas).

The method further comprises a method step for producing the through-holes 120 in the copper plate 12 which can be performed before or after the welding operation, in particular by drilling, punching, cutting or by other techniques.

Once the plate 12 welded and perforated, becomes a sound absorbing layer 10 over the perforated copper plate 12 positioned to the pipe 11 cover (or cover).

This step of positioning the sound absorption layer 10 may depend on the installation of the mounting structure 15 be performed, which is the cladding panel 14 stops on the layer 13 (acoustic tile) has been previously laid.
