Description

[0001] The present invention relates to a heating and / or cooling ceiling comprising paneling serving as a visible surface, in particular in the form of plasterboard; heat-conducting fin arrangements resting at least partially on the paneling, which comprise heat-conducting fin elements with grooves for receiving a pipe and holding elements; support profiles arranged between adjacent heat-conducting fin arrangements, which are usually also referred to as CD profiles, which 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 can flow, which is at least partially received in the grooves of the heat-conducting fin arrangements, wherein the holding 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 lamella arrangement for such a heating and / or cooling ceiling.

[0002] Such heated and / or cooling ceilings are often designed as suspended ceilings or drywall ceilings and are used to heat and, in particular, cool the space below the ceiling. In such suspended ceilings, base profiles are often attached to the actual ceiling at a distance from it using hangers. The base profiles are usually designed as metal profile rails with a substantially U-shaped cross-section. Support profiles are attached to the base profiles at right angles to these base profiles as a substructure for the heated and / or cooling ceiling. The support profiles, like the base profiles, are usually metal profile strips with a substantially U-shaped cross-section. In an installation situation, the base profiles and the support profiles are usually aligned so that the open side of the substantially U-shaped cross-section points towards the actual ceiling.Heat-conducting fins, particularly made of metal, are arranged between the supporting profiles, and their grooves accommodate a pipe through which a heat transfer medium flows. The visible surface from the room side is formed by a paneling made of building boards, particularly plasterboard, which is attached to the supporting profiles. The building boards serving as the visible surface can also be perforated to impart sound-damping properties to such heated and / or chilled ceilings (acoustic ceilings). Such heated and / or chilled 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 holding elements, which serve to attach the heat-conducting fin arrangements to the supporting profiles.

[0003] The disadvantage of the heating and / or cooling ceiling described in AT 12 602 U1 is its poor acoustic properties, in particular its sound-damping properties.

[0004] This is where the present invention comes in, which is based on the object of at least partially overcoming 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, particularly its sound-damping properties, while providing high heating and / or cooling performance.

[0005] These and other objects are achieved by a heating and / or cooling ceiling having the features of claim 1 and by a heat-conducting slat arrangement having 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 recognized that the acoustic properties, in particular the sound-damping properties, of a heated and / or chilled ceiling can be improved simply by providing recesses in the heat-conducting slat elements. Occurring sound waves pass through these recesses, where they are dampened between the actual room ceiling and the paneling of the inventive heated and / or chilled ceiling. Since the heat-conducting slat elements can rest directly on the paneling, the heating and / or cooling performance achievable by the inventive heated and / or chilled ceiling remains high.

[0007] Accordingly, the present invention lies in the provision of a heating and / or cooling ceiling comprising a paneling serving as a visible surface, in particular in the form of plasterboard; heat-conducting lamella arrangements resting at least partially on the paneling, which comprise heat-conducting lamella elements with grooves for receiving a pipe and holding elements; support profiles arranged between adjacent heat-conducting lamella arrangements, which 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 can flow, which is at least partially received in the grooves of the heat-conducting lamella arrangements, wherein the holding elements comprise connecting elements facing the support profiles for connecting the heat-conducting lamella arrangements to the support profiles, wherein the heating and / or cooling ceiling is characterized according to the invention bythat at least one heat-conducting lamella element has a plurality of recesses. Furthermore, the present invention relates to a heat-conducting lamella arrangement for a heating and / or cooling ceiling, comprising at least two heat-conducting lamella elements having grooves for receiving a pipe through which a heat transfer medium can flow, and retaining elements for connecting the heat-conducting lamella arrangements to the supporting profiles of the heating and / or cooling ceiling. The retaining elements comprise connecting elements facing the supporting profiles for connecting the heat-conducting lamella arrangements to the supporting profiles of the heating and / or cooling ceiling. At least one heat-conducting lamella element has a plurality of recesses.

[0008] In preferred embodiments of the present invention, a plurality of heat-conducting lamella arrangements of the heating and / or cooling ceiling according to the invention comprise at least one heat-conducting lamella element with a plurality of recesses. Particularly preferably, all heat-conducting lamella elements of at least one heat-conducting lamella arrangement, in particular a plurality of heat-conducting lamella arrangements, of the heating and / or cooling ceiling according to the invention comprise a plurality of recesses. In particular, the wall-side heat-conducting lamella arrangements, but also other heat-conducting lamella arrangements in a heating and / or cooling ceiling according to the invention without such heat-conducting lamella elements, can be designed with a plurality of recesses.

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

[0010] It can also be advantageous if the holding elements comprise fastening elements for securing the pipeline in sections. It can be particularly helpful if the fastening elements of the holding elements penetrate the heat-conducting fin elements at least in sections. This secures the holding elements to the heat-conducting fin arrangement without direct contact with the heat-conducting fin elements. Furthermore, this also contributes to securing the pipeline in the heat-conducting fin arrangement. The fastening elements are preferably designed as clamping elements into which the pipeline can be clamped in sections.

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

[0012] It may also be useful 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 thus of the heat-conducting fin arrangements comprising them.

[0013] It can also be helpful if the retaining elements are constructed in multiple parts. This allows the retaining elements to be adapted in terms of size to the requirements of the construction site. Therefore, it is preferable if the individual parts can be connected to one another 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 supporting profiles pointing away from the paneling each have a bent section, via which the supporting profiles are each engaged, in particular connected, with the connecting elements of the holding elements. This can prevent the heat-conducting fin arrangements from being unintentionally lifted towards the actual room ceiling and thus no longer resting flat on the paneling. This ensures reliable thermal contact between the heat-conducting fins and the paneling serving as the visible surface from the room side. By preventing the heat-conducting fin arrangements from being lifted away from the supporting 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 insulation layer arranged on the heat-conducting slat arrangements. Such an insulation layer arranged on the heat-conducting slat 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 the material for the insulation layer. The insulation layer can also enhance the sound-damping properties achieved by the heating and / or cooling ceiling according to the invention.

[0016] It may also be advantageous if the paneling material comprises at least one thermally conductive component, in particular graphite. This further improves the transfer of thermal energy between the heat transfer medium conveyed in the pipe and the space 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 preferable for the paneling of the heating and / or cooling ceiling according to the invention to be provided with holes. This can impart additional sound-damping properties to the heating and / or cooling ceiling according to the invention. It is particularly preferred if the holes in the paneling at least partially open into the recesses in the heat-conducting fin elements.

[0018] It can also be advantageous if at least one heat-conducting lamella arrangement is designed to be foldable in the direction of its longitudinal axis. A foldable heat-conducting lamella arrangement can be easily conveyed between the supporting profiles and thus further simplifies the installation of the heating and / or cooling ceiling according to the invention. The foldability of the holding elements can be achieved particularly easily if the holding elements have a joint element by means of which the heat-conducting lamella arrangement is designed to be foldable in the direction of its longitudinal axis. Additionally or alternatively, it can be advantageous if the foldability of the at least one heat-conducting lamella arrangement in the direction of its longitudinal axis is designed centrally in the at least one heat-conducting lamella arrangement or laterally offset from the central longitudinal axis.It may be preferred if the holding elements have locking elements which, when locked, prevent the at least one heat-conducting lamella arrangement from collapsing. This securely holds the heat-conducting lamella arrangements in the unfolded state. This further reduces the risk of the heat-conducting lamella arrangements falling out of the supporting 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 lamella arrangement comprises at least two heat-conducting lamella elements and holding elements, wherein the holding elements have a joint element by means of which the at least one heat-conducting lamella arrangement is designed to be foldable along its longitudinal axis. In this way, the folding capability of the heat-conducting lamella arrangements in the direction of their longitudinal axis can be realized particularly easily and securely.

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

[0020] It can also be advantageous if the distance between the outer side of the support elements facing the respective support profile and the section of the pipeline closest to the respective support profile is different at both end areas of the respective support element. This significantly simplifies the installation of a heating and / or cooling ceiling according to the invention. As a result, the support elements of the heat-conducting fin arrangements are provided with connecting elements on both sides that extend to different distances to the side.In this way, it is possible to first place the heat-conducting slat arrangement on a support profile with the side on which the longer connecting elements are located, then to move the heat-conducting slat arrangement between the support profiles using a combined sliding and lifting movement and finally to shift the heat-conducting slat arrangement horizontally such that the side of the heat-conducting slat arrangement on which the shorter connecting elements are located rests on the other support profile. In this way, tolerances that occur on site can be compensated for. Furthermore, it is not necessary to shift the support profiles for installing the heating and / or cooling ceiling according to the invention. It is particularly effective if the connecting elements each comprise a cantilever web that differs from one another in terms of their respective length.Such a cantilever web allows the asymmetry in the retaining elements to be implemented particularly easily and effectively. Furthermore, they ensure a secure connection between the heat-conducting fin arrangements and the supporting profiles.

[0021] The above explanations with regard to the heating and / or cooling ceiling according to the invention apply accordingly to the heat conducting lamella 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-building or layer-building manufacturing process (e.g. 3D printing).

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

[0024] Fig. 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 functions as a visible surface from the room side, i.e., from the interior of the room. The paneling 2 is preferably in the form of plasterboard. Heat-conducting fin arrangements 3, 3', 3'' are placed on the paneling 2 in the heating and / or cooling ceiling 1 according to the invention. Fig. In the embodiment of the heating and / or cooling ceiling 1 according to the invention shown in Fig. 1, only the central heat conducting lamella arrangement 3' is shown completely, while the two lateral heat conducting lamella arrangements 3, 3'' are each shown only in an edge region.

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

[0026] As can be seen from the Fig. As can be seen from the schematic plan view of the heat-conducting lamella arrangement 3' shown in Figure 3, the heat-conducting lamella elements 31 have a plurality of cutouts 33, 34. Occurring sound waves pass through these cutouts 33, 34 and are then dampened between the actual room ceiling and the paneling 20 of the heating and / or cooling ceiling 1 according to the invention, whereby the acoustic properties, in particular the sound-damping properties, of the heating and / or cooling ceiling 1 according to the invention are improved. The cutouts 33, 34 are arranged in the respective heat-conducting lamella elements 31 in the region of the grooves 4: In the embodiment shown, a section of the groove 4 of the heat-conducting lamella elements 31 is removed by each cutout 33, 34 in the region of the grooves 4. Furthermore, the cutouts 33, 34 are evenly distributed in the longitudinal direction of the heat-conducting lamella elements 31.

[0027] The holding elements 32 comprise fastening elements 35, which serve to secure the pipeline 5 in sections. The fastening elements 35 extend through the heat-conducting fin elements 31. As a result, the holding elements 32 are fastened to the heat-conducting fin arrangement 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 therein.

[0028] This results in two types of recesses 33, 34, namely, on the one hand, recesses 33 which are not penetrated by fastening elements 35 and thus serve entirely for the sound-damping properties of the heating and / or cooling ceiling 1 according to the invention, and, on the other hand, recesses 34 which are penetrated by fastening elements 35 and contribute less to the sound-damping properties but rather to the fastening of the holding elements 32 to the heat-conducting slat arrangement 3' of the heating and / or cooling ceiling 1 according to the invention.

[0029] According to the Fig. 2, the holding element 32 comprises on both sides of the end regions 38, 38' a connecting element 36, 36' facing the support profile 6, 6' at this end region 38, 38'. As can be seen from Fig. 2, the connecting elements 36, 36' are hook-shaped, with the two connecting elements 36, 36' being mirror-symmetrical to one another. In alternative embodiments, the connecting elements 36, 36' can also differ with regard to the distance between the outer side of the holding element 32 facing the respective support profile 6, 6' and the section of the pipeline 5 closest to the respective support profile 6, 6' at both end regions 38, 38' of the respective holding element 32. This is expediently achieved in that the webs 37, 37' of the hook-shaped connecting elements 36, 36', which run horizontally in an installed situation, have different lengths. This facilitates the installation of the heating and / or cooling ceiling 1 according to the invention. In alternative embodiments, the holding elements 32 can also each have a joint element.The hinged element allows the support 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 holding elements 32 can be made are metallic materials and suitable plastics. On their outer sides, the holding elements 32 comprise connecting elements 36, 36', which serve to connect the heat-conducting fin arrangements 3, 3', 3'' to the 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 flat objects and are 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 aligned 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 comprise reinforcements arranged in the groove 4 of the respective heat-conducting fin elements 31. Such reinforcements increase their stability. This allows the weakening caused by the recesses 33, 34 to be compensated.

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

[0033] The pipe 5 is accommodated at least in sections in the grooves 4 of the heat-conducting fin elements 31. A heat transfer medium flows through the pipe 5 and thus serves for air conditioning (heating and / or cooling) the room located below the heated 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, during heating operation they transfer thermal energy of the heat transfer medium in the pipe 5 to the paneling 2. During cooling operation of the heated and / or cooling ceiling 1 according to the invention, thermal energy from the interior of the room is transferred via the paneling 2 to the heat transfer medium guided in the pipe 5 and dissipated by the heat transfer medium, with the heat-conducting fins 3 serving as transmitters.

[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 two 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' pointing away from the base 7 are each bent towards the profile interior of the support profile 6. The support profiles 6, 6' thus each have a bent section 9, 9' at the ends of their legs 8, 8' pointing away from the base 7. The connecting elements 36, 36' of the heat-conducting fin arrangements 3, 3', 3'' adjacent to the respective support profiles 6, 6', which are hook-shaped in the embodiment of the present invention shown in the figures, can rest against the respective bent sections 9, 9'.

[0035] To install the heat-conducting lamella arrangements 3' in the heating and / or cooling ceiling 1 according to the invention, the heat-conducting lamella arrangement 3' is first placed with the 36 on the support profile 6. The heat-conducting lamella arrangement 3' is then raised by rotating until the side with the other connecting element 36' is located above the support profile 6'. Then, the holding element 32 is moved in the direction of the support profile 6' with the longer connecting element 36 resting on the support profile 6. The heat-conducting lamella arrangements 3' are 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 lamella arrangement 3' is shown in Fig. 1 shown.

[0036] Finally, in the heating and / or cooling ceiling 1 according to the invention, an insulation layer 20 is placed on the side of the heat-conducting lamella arrangements 3, 3', 3'' facing away from the paneling 2. The insulation layer 20 can also be omitted in other embodiments of the heating and / or cooling ceiling 1 according to the invention. For reasons of simplification, the insulation layer 20 in Fig. 2 and Fig.3 is not shown, as it is not relevant for the description of the retaining element 32 and the assembly. The insulation layer 20 prevents an exchange of thermal energy between the heating and / or cooling ceiling 1 according to the invention and the space between the actual room ceiling and the heating and / or cooling ceiling 1 according to the invention, which contributes significantly to good heating and / or cooling performance of the heating and / or cooling ceiling 1 according to the invention. Likewise, the insulation layer 20 can comprise a fibrous insulating material. This increases the sound-damping properties achieved by the heating and / or cooling ceiling 1 according to the invention and further enhances comfort. In addition, the fibrous insulating material can be encapsulated in a polymeric film to prevent fiber flight.

[0037] In the embodiment of the heated and / or cooling ceiling 1 according to the invention shown in the figures, a panel 2 made of unperforated plasterboard serves as the visible surface from the room side. In alternative embodiments, the panels of the panel 2 can also be provided with holes to impart additionally improved sound-damping properties to the heated and / or cooling ceiling 1 according to the invention. 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 corresponding 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 illustrated in the figures. It is to be understood that the present invention is not limited to the embodiments illustrated in the figures. Rather, the scope of the present invention is determined from the appended claims.
