FLOOR COATING BLADE, WALL OR CEILING, HEATING OR

REFRESHING

TECHNICAL FIELD AND OBJECT OF THE INVENTION

The invention relates to the field of floor coverings, wall or ceiling formed ^of a blade assembly, such as wooden floors intended to be installed indoors or outdoors.

More specifically, the present invention relates to coating plates incorporating structural means capable of allowing to cool or heat a volume of air located near said coating.

STATE OF THE ART The general problem as regards ^the operation of coating blades, typically made of plastic, intended to coat soil, eg outdoor terraces or interior rooms ^of a building, walls, including external façades , interior walls, or palisades, or ceilings, exterior or interior, to participate in the regulation of the temperature near said coating blades.

In this context, ^the prior art comprises floor heating systems. Thus, there are many known examples of floorboards or carpets incorporating heating means. A first category of known systems comprises coating parts incorporating electric heating son. Another category of known systems includes channels for diffusing a fluid, usually liquid, in the floor, or more often in the slab underneath, to participate in the regulation of the temperature in the volume located above or beside.

For example, EP 058891111 discloses a cladding blade system comprising channels in which electrical wires are deployed and energized to heat the volume adjacent to said blades.

Those ^skilled in the art knows many such examples including the use of electric son implanted into floor panels or carpeting, primarily for heating a room of a building. This first category of known systems nevertheless has various disadvantages. First, these systems are important consumers of electrical energy. On the other hand, these systems are relatively complex to install and requires the services of a professional, especially for electrical wiring. Finally, these systems are only able ^to provide heating ^for a room, and were not able to provide a refresh function.

The state of the art also includes many examples of a system providing for the development of channels capable of diffusing a fluid, in particular a liquid heat vector. These channels are generally intended to be built in the slab, the said slab then being covered with ^a coating of parquet type carpet or tile.

These known systems necessarily include complex hydraulic circuits and are particularly heavy to implement and expensive. ^The intervention of professionals is absolutely essential and the risks inherent in the possibility of leakage in the hydraulic system used in such systems are important.

Most of these systems are also configured to heat a volume of air, not to cool it. In an attempt to overcome this deficiency, systems have been developed to allow a flooring assembly to heat and / or cool a room. Thus, the document FR 3009008 A1 describes a heating and / or cooling system, in which grooves are arranged in the floor in order to receive tubes allowing the passage of fluid, the fluid being able to be hot, for heating a room, or cold , to refresh it.

However, this system requires the implementation ^of a hydraulic circuit for conveying the fluid, with all that this implies in terms of complexity (sealing, technical installation work), cost and risk of damage in case leak.

There is therefore a need for a new type of flooring, wall or ceiling, which include integrated means to heat and / or cool a volume of air located nearby, which is ^simple installation and use safe. For this purpose, the present invention relates to flooring, wall or ceiling boards, in particular plastic material and typically TECKSYNTESE®, incorporating in their mass channels to allow the passage of flows, in particular ^of hot or cold air, to heat or cool an external or internal volume proximate said coating.

DETAILED DESCRIPTION OF THE INVENTION

The invention is presented primarily through the embodiments shown in the figures, for a use of the coating blade in accordance with ^the invention as flooring strip, typically floorboards. However, ^other applications are also covered by the present invention, in particularly ^the use of coating blades in accordance with ^the invention for use to form a wall lining (interior wall, outer facade fence ... etc.) or ceiling. Referring to Figure 1, the present invention relates primarily to a coating plate 1, typically plastic material, and preferably TECKSYNTESE® or optionally PVC loaded with aluminum powder. The cladding blades 1 are intended to be fixed, in particular permanently bonded, to a surface to be covered, such as a floor, a wall or a ceiling.

According to the present invention, channels 10 are arranged longitudinally in the mass of the coating blade 1, for circulating and guiding ^a flow, in particular ^air heated or unheated air or ^air cool or cold.

Between the channels 10 arranged in the mass of the blade 1, spaces are interposed to form a volume 1 1 able to receive glue.

According to an embodiment, said glue, whose primary function is ^to provide bonding of the coating blades 1 on the surface to be coated may comprise aluminum powder, or any other type of suitable powder for the purpose to ^increase the thermal conductivity of said coating blades 1.

The coating blades 1 themselves then contribute to further perform a function of ^{the heat} exchanger.

In addition, as shown in the embodiments of Figures 1 and 2, the cladding blades 1 are intended to cooperate to form assemblies of blades forming floor coverings, wall or ceiling.

Thus, a coating blade 1 may comprise on both sides ^of its longitudinal edges, complementary means 12, 13 for fixing, for example by clipping, coating blades 1 contiguous.

As mentioned above, air is blown into the channels 10 formed in the mass of coating strips 1 assembled together. Said channels 10 are arranged in such a way that the channels 10 of two longitudinally assembled cladding blades coincide so as to form air circulation channels extending over the entire length of said assembled blades. According to the preferred embodiment, the air intended to circulate in the channels

10 is air, heated or not. This air can be air from outside or inside a building. As said before, it may have been heated, but it may also have been cooled using associated air conditioning means.

For example, in one embodiment, the flooring, wall or ceiling formed coating blades 1 according to ^the invention can be connected to a heat pump device or to any type of thermodynamic system or any means heating or air conditioning system capable of heating or cooling the ^air flow.

The ^air thus heated or cooled, or at room temperature or simply for ^extracting ^the external environment or the internal volume of a vessel, is intended to be injected by suitable means, such as ventilation means into the channels 10, via an ^air inlet provided in at least one blade end ^of ^the assembly of coating blades considered.

The air thus flows in one direction in the channels 10 between an ^air inlet provided at least in an inlet end blade of ^the blade assembly and an ^air outlet provided at least one blade of outlet end of ^the blade assembly. ^If it is heated, the air heats the volume close to the coating, for example the room of the building in which said coating covers the ground; ^if it ^is not heated, or if it is cooled, ^the air ^is used ^to remove heat and thus cool the volume located adjacent to said coating, for example the volume close to the floor ^of an outdoor terrace.

3 shows an example of using a coating blade assembly 1 according to ^the invention. Coating said one blade assembly is installed here to form a floor covering ^an outer terrace.

The ventilation means 20 facilitate the circulation of air in the channels of coating blades 1. In this ^case, ^the blown air is at ambient temperature of the external environment or the internal volume of a room located near and the ^air circulation allows to refresh the coating blades 1 and the volume ^of air located above. In practice, by this method, a decrease in the surface temperature of the coating blade 1 between 3 and 5 degrees may be observed due to the circulation ^of air at room temperature into the channels 10 of the blades 1. In fact, heat exchange between the hot surface of the coating blade and ^the air circulating in the channels 10 occurs. The flow ^of air being heated by capturing the heat from the outer surface of the coating blade 1 is discharged through the discharge pipe forming a chimney 21 connected to a blade ^outlet end of ^the blade assembly and thereby forming an ^air outlet.

Thus, the ventilation means 20 to help ^the extraction of ^the air flowing through the channels 10 and the flow of air that captured heat ^s' evacuated via the chimney 21.

According to another embodiment not shown, ^using a coating blade assembly 1 according to the present invention, installed to form the coating ^of an outdoor fence, it is possible to obtain the refresh 3 5 degrees, mentioned above, to facilitate the maintenance of a plant wall leaning against said fence.

FIGS. 4 and 5 show a particular embodiment of a heating or cooling system implementing a coating blade assembly 1 according to the invention, as well as heating or cooling means 30.

For example, the means 30 may constitute a heating means and coating blades 1 form a parquet installed ^inside ^a building. The ^air circulating in the channels 10 is then heated by the heating means 30 which instill hot ^air in an air circuit connected to the channel 10, allowing the flow ^of heated air into the floor, so as to heat the room .

It is recalled that, to improve the efficiency of the system, it is planned to ^increase the thermal conductivity of the coating. For example, in one embodiment, the powder of ^aluminum, or an equivalent compound, is dispersed in the mass of coating blades 1 when they are manufactured. Alternatively, compatible previous, powder of ^aluminum, or an equivalent compound may be dispersed in the adhesive used to attach the coating blades 1 on the surface to be coated, namely a floor, a wall, a fence, a ceiling ... etc. Thus, in summary, the present invention firstly relates to coating blades 1 of plastic material, typically TECKSYNTESE®, including 10 longitudinally arranged channels in the mass of said blades and for circulating ^air, heated or not.

Coating blades are designed to be assembled to form a flooring, wall or ceiling, and s ^integrate to a volume of the temperature control system located in proximity to said coating. It should be noted, moreover, that the invention is not limited to the embodiments described, by way of examples, and is capable of variants within the reach of the skilled person.
