Description

[0001] The present invention relates to a heating and / or cooling ceiling comprising a covering serving as a visible surface, in particular in the form of gypsum plasterboard; heat-conducting fin arrangements resting at least partially on the covering, comprising heat-conducting fin elements with grooves for receiving a pipe and retaining elements; support profiles arranged between adjacent heat-conducting fin arrangements, which are also commonly referred to as CD profiles and have a substantially U-shaped cross-section with a base and legs connected to the base; and a pipe through which a heat transfer medium flows, which is received at least partially in the grooves of the heat-conducting fin arrangements, wherein the retaining elements comprise connecting elements facing the support profiles for connecting the heat-conducting fin arrangements to the support profiles.Furthermore, the present invention relates to a heat-conducting fin arrangement for such a heating and / or cooling ceiling.

[0002] Such heating and / or cooling ceilings are often installed as suspended or drywall ceilings and are used for heating and, in particular, cooling the room below. In these suspended ceilings, base profiles are typically attached to the actual room ceiling at a distance from it using hangers. The base profiles are usually metal profile rails with a generally U-shaped cross-section. Support profiles, which serve as the substructure for the heating and / or cooling ceiling, are attached to the base profiles at right angles to them. These support profiles, like the base profiles, are usually metal profile strips with a generally U-shaped cross-section. In an installed installation, the base and support profiles are typically oriented so that the open side of the generally U-shaped cross-section faces the actual room ceiling.Heat-conducting fins, particularly those made of metal, are arranged between the support profiles. A pipe carrying a heat transfer medium is accommodated in the grooves of these fins. The visible surface from the room side is a covering made of building panels, particularly gypsum plasterboard, which are attached to the support profiles. These building panels can also be perforated to give such heating and / or cooling ceilings sound-absorbing properties (acoustic ceilings). Such heating and / or cooling ceilings are described, for example, in AT 12 602 U1. According to AT 12 602 U1, the heat-conducting fin elements have hook-shaped connecting elements on both sides of their mounting elements, which serve to attach the heat-conducting fin assemblies to the support profiles.

[0003] The heating and / or cooling ceiling described in AT 12 602 U1 is considered to have a disadvantage due to its lack of acoustic properties, in particular its sound-absorbing properties.

[0004] This is where the present invention comes in, which aims to overcome at least some of the disadvantages of the prior art. In particular, the heating and / or cooling ceiling according to the invention is intended to be improved with regard to its acoustic properties, especially its sound-absorbing properties at high heating and / or cooling output.

[0005] These and other problems are solved by a heating and / or cooling ceiling with the features of claim 1 and by a heat-conducting fin arrangement with the features of claim 10. Preferred embodiments of the present invention are described in the dependent claims.

[0006] According to the present invention, it has been found that the acoustic properties, in particular the sound-absorbing properties, of a heating and / or cooling ceiling can be improved simply by incorporating recesses in the heat-conducting fin elements. Sound waves pass through these recesses, where they are dampened between the actual ceiling and the cladding of the heating and / or cooling ceiling according to the invention. Since the heat-conducting fin elements can rest directly on the cladding, the heating and / or cooling capacity achievable with the heating and / or cooling ceiling according to the invention remains high.

[0007] Accordingly, the present invention comprises a heating and / or cooling ceiling comprising a covering serving as a visible surface, in particular in the form of gypsum plasterboard; heat-conducting fin arrangements at least partially resting on the covering, the heat-conducting fin elements having grooves for receiving a pipe and retaining elements; support profiles arranged between adjacent heat-conducting fin arrangements, having a substantially U-shaped cross-section with a base and legs connected to the base; and a pipe through which a heat transfer medium flows, which is received at least partially in the grooves of the heat-conducting fin arrangements, wherein the retaining elements comprise connecting elements facing the support profiles for connecting the heat-conducting fin arrangements to the support profiles, wherein the heating and / or cooling ceiling is characterized according to the invention bythat at least one heat-conducting fin element has a plurality of recesses. Furthermore, the present invention relates to a heat-conducting fin arrangement for a heating and / or cooling ceiling, comprising at least two heat-conducting fin elements having grooves for receiving a pipe through which a heat transfer medium flows, and retaining elements for connecting the heat-conducting fin arrangements to the support profiles of the heating and / or cooling ceiling, wherein the retaining elements comprise connecting elements facing the support profiles for connecting the heat-conducting fin arrangements to the support profiles of the heating and / or cooling ceiling, wherein at least one heat-conducting fin element has a plurality of recesses.

[0008] In preferred embodiments of the present invention, several heat-conducting fin assemblies of the heating and / or cooling ceiling according to the invention have at least one heat-conducting fin element with a plurality of recesses. Particularly preferred embodiments include all heat-conducting fin elements of at least one heat-conducting fin assembly, and in particular of several heat-conducting fin assemblies, of the heating and / or cooling ceiling according to the invention, comprising a plurality of recesses. In particular, the wall-side heat-conducting fin assemblies, but also other heat-conducting fin assemblies in a heating and / or cooling ceiling according to the invention, can be configured without such heat-conducting fin elements with a plurality of recesses.

[0009] With regard to the heating and / or cooling ceiling according to the invention, it can be advantageous if the recesses of the heat-conducting fin elements are at least partially located in the area of ​​the grooves. Recesses in the area of ​​the grooves have proven to be acoustically effective and only minimally reduce the stability of the heat-conducting fin elements. Preferably, the recesses are evenly distributed along the grooves.

[0010] It can also be advantageous if the retaining elements include fasteners for section-by-section securing the pipeline. It can be particularly helpful if the fasteners of the retaining elements penetrate the heat-conducting fin elements, at least in sections. This allows the retaining elements to be attached to the heat-conducting fin assembly without direct contact with the fins. Furthermore, this also contributes to fixing the pipeline within the heat-conducting fin assembly. The fasteners are preferably designed as clamping elements into which the pipeline can be clamped and fixed section by section.

[0011] It can also be beneficial if the heat-conducting fin elements have reinforcements. Such reinforcements increase their stability. Preferably, the reinforcements are arranged in the grooves of the heat-conducting fin elements. This compensates for the weakening caused by the recesses.

[0012] It can also be beneficial for the heat-conducting fin elements to have raised edges, grooves, and / or beads along their length. This significantly improves the stability of the heat-conducting fin elements and, consequently, of the heat-conducting fin assemblies comprising them.

[0013] It can also be helpful if the retaining elements are multi-part. This allows the size of the retaining elements to be adapted to the requirements on the construction site. Therefore, it is preferable if the individual parts can be connected to each other along the longitudinal axis of the respective heat-conducting fin arrangement.

[0014] It can also be helpful if the ends of the legs of the support profiles pointing away from the sheathing each have a bending section through which the support profiles engage with, and in particular connect to, the connecting elements of the retaining elements. This prevents the heat-conducting fin arrangements from unintentionally lifting towards the actual ceiling and thus no longer lying flat on the sheathing. This ensures reliable thermal contact between the heat-conducting fins and the sheathing, which serves as the visible surface from the room side. By preventing the heat-conducting fin arrangements from lifting away from the support profiles, the installation of the heating and / or cooling ceiling according to the invention is further simplified.

[0015] In preferred embodiments of the heating and / or cooling ceiling according to the invention, it can further comprise an insulating layer arranged on the heat-conducting fin arrangements. Such an insulating layer arranged on the heat-conducting fin arrangements prevents thermal exchange between the area of ​​the actual room ceiling and the heating and / or cooling ceiling according to the invention. This also contributes to good heating and / or cooling performance of the heating and / or cooling ceiling according to the invention. For example, glass wool, a foamed polymer material, and the like can be used as materials for the insulating layer. The insulating layer can also enhance the sound-absorbing properties achieved by the heating and / or cooling ceiling according to the invention.

[0016] It can also be advantageous if the cladding material comprises at least one thermally conductive component, in particular graphite. This further improves the transfer of thermal energy between the heat transfer medium carried in the pipeline and the room conditioned by the heating and / or cooling ceiling according to the invention. This also increases the perceptible heating and / or cooling performance of the heating and / or cooling ceiling according to the invention.

[0017] Additionally or alternatively, it may be preferred if the sheathing of the heating and / or cooling ceiling according to the invention is provided with holes. This can give the heating and / or cooling ceiling according to the invention additional sound-absorbing properties. It is particularly preferred if the holes in the sheathing open at least partially into the recesses in the heat-conducting fin elements.

[0018] It can also be advantageous if at least one heat-conducting fin assembly is designed to be hinged along its longitudinal axis. A hinged heat-conducting fin assembly can be easily moved between the support profiles, thus further simplifying the installation of the heating and / or cooling ceiling according to the invention. The hingeability of the retaining elements is particularly easy to achieve if the retaining elements have a hinge element that allows the heat-conducting fin assembly to be hinged along its longitudinal axis. Additionally or alternatively, it can be advantageous if the hinge of the at least one heat-conducting fin assembly is located centrally within the assembly or laterally offset from the central longitudinal axis.It may be advantageous if the retaining elements have locking elements that, in the locked state, prevent the at least one heat-conducting fin assembly from folding together. This securely holds the heat-conducting fin assemblies in the unfolded state. This further reduces the risk of the heat-conducting fin assemblies falling out of the support profiles in the finished heating and / or cooling ceiling according to the invention. In particularly preferred embodiments of the heating and / or cooling ceiling according to the invention, at least one heat-conducting fin assembly comprises at least two heat-conducting fin elements and retaining elements, wherein the retaining elements have a hinge element by which the at least one heat-conducting fin assembly is designed to be foldable along its longitudinal axis. In this way, the foldability of the heat-conducting fin assemblies in the direction of their longitudinal axis can be implemented particularly easily and reliably.

[0019] It can also be helpful if the retaining elements include connecting elements facing the support profiles for attaching the heat-conducting fin arrangements to the support profiles.

[0020] It can also be advantageous if the distance between the outer surface of the retaining elements facing the respective support profile and the section of the pipeline closest to the respective support profile differs at both end regions of the respective retaining element. This significantly simplifies the installation of a heating and / or cooling ceiling according to the invention. As a result, the retaining elements of the heat-conducting fin arrangements are provided on both sides with connecting elements that project to the side at different distances.In this way, it becomes possible to first place the heat-conducting fin assembly onto a support profile with the side on which the longer connecting elements are located, then to move the heat-conducting fin assembly between the support profiles using a combined sliding and lifting motion, and finally to shift the heat-conducting fin assembly horizontally so that the side of the heat-conducting fin assembly with the shorter connecting elements rests on the other support profile. This allows for the compensation of tolerances occurring on the construction site. Furthermore, it is not necessary to move the support profiles for the installation of the heating and / or cooling ceiling according to the invention. It is particularly effective if the connecting elements each include a cantilever web that differs in length from one another.Such a cantilevered support structure allows for particularly simple and effective implementation of the asymmetry in the support elements. Furthermore, it ensures a secure connection between the heat-conducting fin arrangements and the support profiles.

[0021] The preceding explanations relating to the heating and / or cooling ceiling according to the invention apply accordingly to the heat-conducting fin arrangement according to the invention.

[0022] The heating and / or cooling ceiling according to the invention, as well as individual parts thereof, can also be manufactured line by line or layer by layer using a line-by-line or layer-by-layer manufacturing process (e.g. 3D printing).

[0023] The present invention will now be explained in detail with reference to the embodiments illustrated in the figures. Figure 1 is a schematic cross-sectional view of a heating and / or cooling ceiling according to an embodiment of the present invention; Figure 2 is a schematic, enlarged cross-sectional view of a [missing information] in the [missing information] Fig. 1 The heat-conducting fin arrangement used in the heating and / or cooling ceiling according to the invention is shown; and Figure 3, which is shown in Fig. 2 The heat-conducting fin arrangement shown is shown in a schematic top view.

[0024] Fig. 1 Figure 1 shows a section of a heating and / or cooling ceiling 1 according to an embodiment of the present invention in a schematic cross-sectional view. The heating and / or cooling ceiling 1 according to the invention comprises a paneling 2, which serves as the visible surface from the room side, i.e., from the interior of the room. The paneling 2 is preferably in the form of gypsum plasterboard. Heat-conducting fin arrangements 3, 3', 3" are laid on the paneling 2 in the heating and / or cooling ceiling 1 according to the invention. Fig. 1 In the illustrated embodiment of the heating and / or cooling ceiling 1 according to the invention, only the central heat-conducting fin arrangement 3' is shown in full, while the two lateral heat-conducting fin arrangements 3, 3" are only shown in a peripheral area.

[0025] In the Fig. 1 The embodiment of the heating and / or cooling ceiling 1 according to the invention, as illustrated, comprises the Fig. 1 centrally depicted heat-conducting fin arrangement 3', which is in Fig. 2 shown in a schematic, enlarged cross-sectional view are three heat-conducting fin elements 31 and two retaining elements 32 (see. Fig. 3 ), which are arranged longitudinally in the heat-conducting fin assembly 3' and are attached to the heat-conducting fin assembly 3' via the pipe 5. In the Fig. 1 In the illustrated embodiment of the heating and / or cooling blanket 1 according to the invention, the retaining elements 32 are designed as retaining brackets.

[0026] As from the in Fig. 3 As can be seen from the schematic top view of the heat-conducting fin arrangement 3' shown, the heat-conducting fin elements 31 have a plurality of recesses 33, 34. Sound waves pass through these recesses 33, 34 and are then dampened between the actual ceiling and the paneling 20 of the heating and / or cooling ceiling 1 according to the invention, thereby improving the acoustic properties, in particular the sound-absorbing properties, of the heating and / or cooling ceiling 1 according to the invention. The recesses 33, 34 are arranged in the respective heat-conducting fin elements 31 in the area of ​​the grooves 4: In the illustrated embodiment, each recess 33, 34 removes a section of the groove 4 of the heat-conducting fin elements 31. The recesses 33, 34 are also evenly distributed in the longitudinal direction of the heat-conducting fin elements 31.

[0027] The retaining elements 32 comprise fastening elements 35, which serve to secure the pipeline 5 section by section. The fastening elements 35 extend through the heat-conducting fin elements 31. This allows the retaining elements 32 to be attached to the heat-conducting fin assembly 3' without direct contact with the heat-conducting fin elements 31. In the illustrated embodiment, the fastening elements 35 are designed as clamping elements. Sections of the pipeline 5 are clamped into them.

[0028] Thus, two types of recesses 33, 34 result, namely, on the one hand, recesses 33 that are not penetrated by fastening elements 35 and thus serve entirely the sound-absorbing properties of the heating and / or cooling ceiling 1 according to the invention, and on the other hand, recesses 34 that are penetrated by fastening elements 35 and contribute less to the sound-absorbing properties, but rather to the fastening of the retaining elements 32 to the heat-conducting fin arrangement 3' of the heating and / or cooling ceiling 1 according to the invention.

[0029] According to the in Fig. 2 In the illustrated embodiment, the retaining element 32 comprises a connecting element 36, 36' on both sides at the end regions 38, 38', each facing the support profile 6, 6' at this end region 38, 38'. As shown Fig. 2 As can be seen, the connecting elements 36, 36' are hook-shaped, with the two connecting elements 36, 36' being mirror-symmetrical to each other. In alternative embodiments, the connecting elements 36, 36' can also differ with respect to the distance between the outer surface of the retaining element 32 facing the respective support profile 6, 6' and the section of the pipe 5 nearest to the respective support profile 6, 6' at both end regions 38, 38' of the respective retaining element 32. Advantageously, this is achieved by having the horizontally extending webs 37, 37' of the hook-shaped connecting elements 36, 36' of different lengths in an installation situation. This facilitates the installation of the heating and / or cooling ceiling 1 according to the invention. In alternative embodiments, the retaining elements 32 can also each have a hinge element.The hinge element allows the retaining elements to be folded along their longitudinal axis. This can also simplify the installation of the heating and / or cooling ceiling 1 according to the invention.

[0030] Preferred materials from which the retaining elements 32 can be manufactured are metallic materials and suitable plastics. On their outer surfaces, the retaining elements 32 comprise connecting elements 36, 36', which serve to connect the heat-conducting fin arrangements 3, 3', 3" to support profiles 6, 6'. In the illustrated embodiment of the heating and / or cooling ceiling 1 according to the invention, the connecting elements 36, 36' are designed as retaining lugs.

[0031] The heat-conducting fin elements 31 are planar objects and preferably made of metal, in particular aluminum, sheet steel, and combinations thereof. In the illustrated embodiment, each heat-conducting fin element 31 has a groove 4. Alternatively, the heat-conducting fin elements 31 can also comprise a plurality of grooves 4. The grooves 4 of the heat-conducting fin elements 31 are oriented in the heating and / or cooling ceiling 1 according to the invention such that the open side of the grooves 4 faces the paneling 2. Furthermore, the heat-conducting fin elements 31 include reinforcements arranged in the groove 4 of the respective heat-conducting fin elements 31. Such reinforcements increase their stability. This compensates for the weakening caused by the recesses 33, 34.

[0032] In alternative embodiments of the present invention, the heat-conducting fin elements 31, 31' can have additional raised edges, grooves, and / or beads in their longitudinal direction for stability reasons.

[0033] The pipe 5 is at least partially accommodated in the grooves 4 of the heat-conducting fin elements 31. A heat transfer medium flows through the pipe 5 and thus serves to air-condition (heat and / or cool) the room located below the heating and / or cooling ceiling 1 according to the invention. Due to the good thermal conductivity of the material of the heat-conducting fin elements 31, these transfer thermal energy of the heat transfer medium in the pipe 5 to the paneling 2 during heating operation. During cooling operation of the heating and / or cooling ceiling 1 according to the invention, thermal energy from the room interior is transferred via the paneling 2 to the heat transfer medium carried in the pipe 5 and dissipated by the heat transfer medium, with the heat-conducting fins 3 serving as heat transfer devices.

[0034] According to this embodiment of the heating and / or cooling ceiling 1 according to the invention, a support profile 6, 6' is arranged between each pair of adjacent heat-conducting fin arrangements 3, 3', 3". In the embodiment shown, the support profiles 6, 6' are designed as metal profiles with a substantially U-shaped cross-section. The support profiles 6, 6' comprise a base 7 and two legs 8, 8' connected to the base 7. The ends of the legs 8, 8' extending away from the base 7 are each bent towards the interior of the support profile 6. Thus, the support profiles 6, 6' each have a bent section 9, 9' at the ends of their legs 8, 8' extending away from the base 7. The hook-shaped connecting elements 36, 36' of the respective support profiles, which are designed in the embodiment of the present invention shown in the figures, can be attached to the respective bent sections 9, 9'. 6, 6' adjacent heat conducting fin arrangements 3, 3', 3" are in contact.

[0035] To mount the heat-conducting fin arrangements 3' in the heating and / or cooling ceiling 1 according to the invention, the heat-conducting fin arrangement 3' is first placed with the 36 onto the support profile 6. The heat-conducting fin arrangement 3' is then rotated and lifted until the side with the other connecting element 36' is located above the support profile 6'. The retaining element 32 is then moved towards the support profile 6' with the longer connecting element 36 resting on the support profile 6. The heat-conducting fin arrangement 3' is then lowered evenly until the connecting elements 36, 36' rest on the respective support profile 6, 6'. The resulting arrangement with respect to the heat-conducting fin arrangement 3' is shown in Fig. 1 shown.

[0036] Finally, in the heating and / or cooling ceiling 1 according to the invention, an insulating layer 20 is applied to the side of the heat-conducting fin arrangements 3, 3', 3" facing away from the paneling 2. The insulating layer 20 can also be omitted in other embodiments of the heating and / or cooling ceiling 1 according to the invention. For the sake of simplicity, the insulating layer 20 is shown in Fig. 2 und 3The insulation layer 20 is not shown, as it is not relevant for describing the retaining element 32 and its assembly. The insulation layer 20 prevents the exchange of thermal energy between the heating and / or cooling ceiling 1 according to the invention and the space between the actual ceiling and the heating and / or cooling ceiling 1 according to the invention, which significantly contributes to the good heating and / or cooling performance of the heating and / or cooling ceiling 1 according to the invention. The insulation layer 20 can also comprise a fibrous insulating material. This enhances the sound-absorbing properties achieved by the heating and / or cooling ceiling 1 according to the invention and further increases comfort. Additionally, the fibrous insulating material can be encapsulated in a polymeric film to prevent fiber shedding.

[0037] In the embodiment of the heating and / or cooling ceiling 1 according to the invention shown in the figures, the visible surface from the room side is a panel 2 made of unperforated gypsum plasterboard. In alternative embodiments, the panels of the panel 2 can also be provided with holes to give the heating and / or cooling ceiling 1 according to the invention additionally improved sound-absorbing properties. To further improve these properties, holes can open at least partially into the recesses 33, 34. In addition, the material of the panel 2 can also contain at least one component with high thermal conductivity, for example, graphite.

[0038] The heating and / or cooling ceiling 1 according to the invention is attached to the actual room ceiling by means of appropriate hangers (not shown).

[0039] The present invention has been described in detail by way of example with reference to the embodiment of the present invention shown in the figures. It is understood that the present invention is not limited to the embodiments shown in the figures. Rather, the scope of the present invention is defined by the accompanying claims.
