    The invention relates to a device for an outer wall with a facade part, a heat coupler and a fastening element for the outer wall.
    Devices are known from the prior art which are spaced from an outer wall and have heat couplers that exchange thermal energy with the outer wall in order to either cool or heat it. EP3336274A1, for example, discloses an outer wall which is preceded by a layer of wood as a facade part, wherein this facade part can also have a static load-bearing function. Between this part of the facade and the outer wall, pipes are laid as heat couplers, which are embedded in a connecting layer. This connecting layer is created by filling the defined cavity between the outer wall and the front part of the facade with cast concrete, for example. Both the connecting layer and the facade part are fixed and spaced from one another by means of dowels, the dowels penetrating the connecting layer and the facade part, but only resting on the outer wall. The pipelines are located within the connecting layer near the dowels or are attached to them, which means that after the cast concrete has hardened, not only the positions of the outer wall, the connecting layer and the facade element, but also the pipelines are fixed. An insulation layer and a weather-resistant layer can also be provided on the outside of the facade part.
    A disadvantage of the prior art, however, is that the pipelines can not directly heat or cool the outer wall, since due to the construction of the wall, the pipelines must be embedded in an additional connecting layer. For this reason, it is proposed to design the connecting layer as a cast layer, which not only increases the construction effort again, but also brings with it the risk that the hardening cast layer will shrink and thus negatively affect the thermal conductivity. In addition, this connecting layer is always heated or cooled by the pipelines, which leads to a delayed heat exchange on the wall and an overall increase in energy consumption. Ultimately, the connection layer must be thermally insulated from the facade part, which increases the space required by the wall.
    The invention is therefore based on the object of showing a space-saving, easily prefabricated device with an energy-efficient heat transfer system.
    The invention solves the problem in that the heat coupler is supported for pressing against the outer wall via an insulating layer against the facade part. The fastening element forms at least one restraint stop for the facade part so that the heat coupler can be pressed against the outer wall via the insulating layer, so that there is particularly efficient thermal contact between the outer wall and the heat coupler. This means that no additional structural measures for heat transfer between the outer wall and the heat coupler, such as a connecting layer that also needs to be tempered, are provided, which also increases the efficiency of the heat transfer and reduces the space requirement of the device. With good thermal conductivity, this type of connection still allows limited freedom of movement of the heat coupler relative to the outer wall, so that, for example, thermal expansions and compressions or other relative position changes of the components do not lead to material stresses between the device and the outer wall. Since only the heat coupler has to be inserted between the outer wall and the facade element, the device can be easily prefabricated and assembled on site. Particularly advantageous construction conditions arise when the device is mounted on an already existing outer wall. However, this is not absolutely necessary, since a not yet standing outer wall can also be assembled with a device according to the invention and then mounted together with the device, for example in a skeleton construction, in a frame. As a result of these measures, the device can be used in the construction of different types of facade, such as curtain walls, element facades, curtain walls, rear-ventilated facades, or the like.
    The space between the facade part and the heat coupler can be used efficiently in that the heat coupler is supported resiliently and under bias against the facade part via an elastic insulating layer. Since the elastic insulation layer generates the prestressing that is necessary to support the heat coupler against the facade part through compression, no additional resilient component is required. The necessary preload can be generated simply via the volume and the elasticity of the insulation material of the insulation layer. For this purpose, for example, an elastic insulation layer, the thickness of which in the relaxed state exceeds the distance between the facade part and the outer wall, can be preassembled on the heat couplers. Before or during the introduction of the heat coupler between the outer wall and the facade part, the insulating material layer is elastically compressed and relaxed again after introduction. Since the elastic insulation layer cannot relax completely due to the distance between the outer wall and the facade part, the remaining compression of the elastic insulation material of the insulation layer generates the spring force or pretension that is required to press the heat coupler on. As an alternative to this, an insulation layer with the necessary pre-tensioning can be created by blowing in the blow-in insulating material on the facade part, whereby the pre-tensioning can also be determined here via the quantity and elasticity of the blown-in insulating material.
    Particularly simple heating conditions arise when the heat coupler comprises an electrical heating element. With an electrical heating element, high temperatures can be provided quickly, depending on the power, so that the outer wall can be heated up quickly. Particularly advantageous construction conditions arise in this connection when the electrical heating element is electrically connected to a photovoltaic element arranged on the facade part, with corresponding regulators being able to be interposed. As a result of this measure, individual devices can be mounted independently of one another without a connection between these devices being necessary.
    The outer wall can not only be heated in an energy-efficient manner, but also cooled in that the heat coupler comprises a temperature control tube attached to a carrier. In a particularly preferred embodiment, the temperature control tube can be flowed through by a heat fluid that is temperature-controlled via the water supply. As a result, the outer wall can not only be simply heated, for example by water, but also simply cooled. The thermal fluid tempered by the heat exchange can then be used as a heat transfer medium for a building heating system, which saves heating costs. The carrier for the heat coupler can consist, for example, of a plate or a grate to which the temperature control tube is attached. In a particularly preferred embodiment, the insulating layer itself can also be closed off from the outer wall with a membrane as a carrier for the temperature control tube. The temperature control tube can be positioned on the carrier, for example, by means of Velcro fasteners, omega profiles or the like, which results in freedom when positioning the temperature control tube on the carrier. For example, it can be arranged in a meandering shape in order to ensure uniform heat transfer from or to the outer wall. The spring force that generates the preload is applied to the carrier and is thus transmitted over a large area to the temperature control tube.
    The efficiency of the heat coupler can be increased in that the side of the heat coupler facing the facade part is at least partially enclosed by the insulating layer. This prevents an air gap from forming between the outer wall and the heat coupler, which has poorer insulation properties than the insulation layer.
    In order to enable a more uniform and thus better heat transfer between the heat coupler and the outer wall, the heat coupler can be a heat conducting plate with temperature control tubes on the facade part. Since the heat conducting sheet has good thermal conductivity, temperature peaks along the temperature control tube can be reduced as a result of these measures and thermal energy can be exchanged over a larger area with the outer wall. In addition, the bearing force generated by the insulation layer can be introduced into the heat coupler more evenly via the surface of the heat conducting sheet, whereby the temperature control tubes are at least partially enclosed by the insulation layer due to the facade-side arrangement, thus avoiding the formation of air gaps.
    The invention also relates to a method for attaching a device to an outer wall, a facade part being fastened to the outer wall at a distance via a fastening element. In order to enable good heat transfer between the outer wall and the heat coupler, it is proposed that a heat coupler be pressed against the outer wall by introducing an insulating layer between the facade part and the heat coupler. In the case of smaller devices, individual insulation layer elements can be prefabricated, whereby a heat coupler can also be applied to the insulation layer elements in advance. For larger devices, on the other hand, it is advantageous if the insulation layer is blown into the free space between the heat coupler and the facade part after the heat coupler has been prepositioned relative to the outer wall.
    In the drawing, the subject matter of the invention is shown, for example. 1 shows a schematic cross section of an outer wall with a device according to the invention in a first embodiment before its assembly, FIG. 2 shows a cross section corresponding to FIG. 1 after assembly of the device, FIG. 3 shows a schematic cross section of an outer wall with a device according to the invention in a second embodiment before its assembly and FIG. 4 shows a cross section corresponding to FIG. 3 after the assembly of the device.
    A device according to the invention for an outer wall 1 comprises a facade part 2 which can be connected to the outer wall 1 via a fastening element 3 and which closes the facade part on the side opposite the outer wall 1. In principle, it does not matter whether the facade part 2 is connected directly or indirectly to the outer wall 1. A heat coupler 4 of the device is supported against the facade part 2 via an insulating layer 5, as shown in FIGS. 2 and 4 can be seen.
    In a preferred embodiment, the insulating layer 5 is designed to be elastic, so that the heat coupler is resilient and supported under prestress and is thus pressed against the outer wall 1 after assembly.
    In one shown in Figs. 1 and 2, the heat coupler 4 can be a temperature control tube 7 attached to a carrier 6. The temperature control tube 7 can, however, also form the heat coupler together with a heat conducting plate 8, as is the case in the embodiment of FIGS. 3 and 4 is shown. The temperature control tube is arranged on the side of the heat conducting sheet 8 facing the facade part 2. In addition to the temperature control tube 7, an electrical heating element not shown in detail in the drawing, for example an electrical resistance heater, can also be provided. Of course, the temperature control tube 7 and the electrical heating element can also be used together.
    In both embodiments, the insulating properties can be improved if the side of the heat coupler 4 facing the facade part 2, which comprises the temperature control tube 7 in both embodiments, is at least partially enclosed by the insulating layer 5.
    To assemble a device according to the invention, it can either be prepositioned as a prefabricated component in front of the outer wall 1, as shown in FIG. 1, and then pressed against the outer wall 1, while the insulating layer 5 as shown in FIG compressed and the fastening element 3 is closed or engages.
    However, the assembly can also largely dispense with prefabricated components, wherein in the in Figs. 3 and 4, the facade part 2 is first attached to the outer wall 1 via the fastening part 3 and the heat coupler 4 is introduced into the space 9 between the facade part 2 and the outer wall 1, after which the remaining space between the facade part 2 and the heat coupler 4 is covered with an insulating layer 5 is filled so that the heat coupler 4 is pressed against the outer wall 1. For this purpose, a closable filling opening 10 can be provided in the facade part 2.
