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 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 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, with a pipe through which a heat transfer medium flows being accommodated in their grooves. The visible surface from the room side is formed by 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-dampening properties to such heated and / or chilled ceilings (acoustic ceiling). The perforation pattern can then also extend through the heat-conducting fins. 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] A disadvantage of the heating and / or cooling ceiling described in AT 12 602 U1 is that existing tolerances cannot be compensated for during installation on site. This may make it impossible to properly hang and attach the overlying heat-conducting fin arrangements to the supporting profiles.

[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 should be safe and precise to install, while allowing for the compensation of tolerances that may occur on site.

[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 was recognized that the installation of a heated and / or cooling ceiling can be considerably simplified by providing the holding elements of the heat-conducting slat elements with connecting elements on both sides that protrude to different extents to the side. In this way, it is possible to first place the heat-conducting slat arrangement on a supporting profile with the side on which the longer connecting elements are located, then to move the heat-conducting slat arrangement between the supporting 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 supporting profile. In this way, tolerances that occur on site can be compensated for.Furthermore, it is not necessary to move the support profiles for the installation of the heating and / or cooling ceiling according to the invention.

[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 the distance between the outer side of the holding elements facing the respective support profile and the section of the pipeline closest to the respective support profile is different at both end regions of the respective holding element. Furthermore, the present invention relates to a heat-conducting lamella arrangement for a heated and / or chilled ceiling, comprising at least two heat-conducting lamella elements having grooves for receiving a pipeline through which a heat transfer medium can flow, and holding elements for connecting the heat-conducting lamella arrangements to the support profiles of the heated and / or chilled ceiling, wherein the holding elements comprise connecting elements facing the support profiles for connecting the heat-conducting lamella arrangements to the support profiles of the heated and / or chilled ceiling.wherein the distance between the outer side of the holding elements facing the respective support profile and the section of the pipeline closest to the respective support profile is different at both end regions of the respective holding element.

[0008] In preferred embodiments of the present invention, several, in particular all, holding elements of a heat-conducting fin arrangement are aligned identically with respect to the connecting elements, ie the longer connecting elements of identically aligned holding elements point in the direction of the same support profile.

[0009] Furthermore, within the scope of the present invention, one or more heat-conducting lamella arrangements with such retaining elements can be present in a heated and / or chilled ceiling, which have connecting elements of different lengths on opposite sides. In particular, the wall-side heat-conducting lamella arrangements, but also other heat-conducting lamella arrangements in a heated and / or chilled ceiling according to the invention, can not be provided with such asymmetric retaining elements.

[0010] With regard to the heating and / or cooling ceiling according to the invention, it can be useful if the connecting elements each comprise a cantilevered web that differs from one another in terms of their respective lengths. Such a cantilevered web allows the asymmetry in the retaining elements to be implemented particularly simply and effectively. Furthermore, they ensure a secure connection between the heat-conducting fin arrangements and the supporting profiles.

[0011] It can also be advantageous if the difference in the distances between the outer side of the holding elements facing the respective support profile and the section of the pipeline closest to the respective support profile at both end regions of the respective holding element is at least 10%, based on the shorter distance. Such a size difference is already sufficient to simplify the installation of the heating and / or cooling ceiling according to the invention. Preferably, however, the difference in the distances between the outer side of the holding elements facing the respective support profile and the section of the pipeline closest to the respective support profile at both end regions of the respective holding element is at least 20%, in particular at least 30%, particularly preferably at least 40%, in each case based on the shorter distance. In absolute values, the difference in length between the distances is at least 15 mm, in particular 20 mm and preferably at least 25 mm.

[0012] 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 slat 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 slats and the paneling serving as the visible surface from the room side. By preventing the heat-conducting slat 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.

[0013] 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.

[0014] It can 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 conducted in the pipe and the room air-conditioned by the heating and / or cooling ceiling according to the invention. This likewise increases the perceptible heating and / or cooling performance of the heating and / or cooling ceiling according to the invention. Additionally or alternatively, it can be preferred if the paneling 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-dampening properties. It is particularly preferred if holes are also present in the heat-conducting lamella elements.It is particularly preferred if the holes in the paneling in the heating and / or cooling ceiling according to the invention open into the holes of the heat-conducting lamella elements.

[0015] 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 retaining elements have locking elements that, when locked, prevent the at least one heat-conducting slat arrangement from collapsing. This securely holds the heat-conducting slat arrangements in the unfolded state. This further reduces the risk of the heat-conducting slat arrangements falling out of the supporting profiles in the finished heating and / or cooling ceiling according to the invention.

[0016] 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 retaining elements, wherein the retaining elements have a hinge 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 reliably.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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).

[0021] In the following, the present invention will be explained in detail with reference to the embodiments shown 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 Fig. 1 illustrated heating and / or cooling ceiling according to the invention; and Figure 3 shows a schematic cross-sectional view of a section of the heating and / or cooling ceiling according to the invention according to Fig. 1 during their assembly.

[0022] Fig. 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. Therein, 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. 1 In the illustrated embodiment of the heating and / or cooling ceiling 1 according to the invention, 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.

[0023] In the Fig. 1 The embodiment of the heating and / or cooling ceiling 1 according to the invention shown in Fig. 1 centrally shown heat conducting fin arrangement 3', which in Fig. 2 shown in a schematic, enlarged cross-sectional view, six heat-conducting fin elements 31 and a plurality of holding elements 32, which are arranged in the longitudinal direction of the heat-conducting fin arrangement 3' and are connected to the heat-conducting fin elements 31, 31'. Fig. 1 In the illustrated embodiment of the heating and / or cooling ceiling 1 according to the invention, the holding elements 32 are designed as holding brackets.

[0024] According to the Fig. 2 In the embodiment shown, the holding element 32 comprises on both sides of the end regions 34, 34' a connecting element 36, 36' facing the support profile 6, 6' at this end region 34, 34'. As can be seen from Fig. 2 As can be seen, the connecting elements 36, 36' are hook-shaped. The connecting elements 36, 36' differ in terms of 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 34, 34' of the respective holding element 32. In the Fig. 2 In the embodiment of the heat conducting lamella arrangement 3' according to the invention shown, this is 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, which in Fig. 2 illustrated by the different lengths X and Y.

[0025] 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.

[0026] In alternative designs, the holding elements can also each have a hinged element. The hinged element allows the holding elements to be folded along their longitudinal axis.

[0027] 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 points in the direction of the paneling 2. A pipe 5 is accommodated at least in sections in the grooves 4 of the heat-conducting fin elements 31, 31'. A heat transfer medium flows through the pipe 5 and thus serves to air-condition (heat and / or cool) the space 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, 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 heating 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 fin elements 31, 31' serving as transmitters.

[0028] 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.

[0029] 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". The support profiles 6, 6' are designed in the embodiment shown as a metal profile 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. Thus, the support profiles 6, 6' each have a bent section 9, 9' at the ends of their legs 8, 8' pointing away from the base 7. At the respective bent sections 9, 9', the connecting elements 36, 36', which are designed in a hook-shaped manner in the embodiment of the present invention shown in the figures, of the respective Support profiles 6, 6' adjacent heat conducting fin arrangements 3, 3', 3".

[0030] The assembly of the heat conducting lamella arrangements 3, 3', 3" in the heating and / or cooling ceiling 1 according to the invention is shown schematically in Fig. 3 shown using the example of the heat-conducting fin arrangement 3'. For this purpose, the heat-conducting fin arrangement 3' is first placed with the longer connecting element 36 on the support profile 6. The heat-conducting fin arrangement 3' is then raised by rotating until the side with the shorter connecting element 36' is located above the support profile 6'. Then, with the longer connecting element 36 resting on the support profile 6, the holding element 32 is moved in the direction of the support profile 6'. This side with the shorter connecting element 36' is finally lowered until the shorter connecting element 36' rests on the support profile 6'. The resulting arrangement with respect to the heat-conducting fin arrangement 3' is shown in Fig. 1 shown. In this way, tolerances occurring on site, for example with regard to the distance between the support profiles 6, 6', can be compensated. Furthermore, it is also not necessary to move the support profiles 6, 6' for the installation of the heating and / or cooling ceiling 1 according to the invention.

[0031] 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 und 3not shown, as it is not important for the description of the holding 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-dampening properties achieved by the heating and / or cooling ceiling 1 according to the invention and further increases comfort. In addition, the fibrous insulating material can be encapsulated in a polymeric film to prevent fiber flyaway.

[0032] In the embodiment of the heating 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 additional sound-damping properties to the heating and / or cooling ceiling 1 according to the invention. To further improve these properties, holes can then preferably also be provided in the heat-conducting fin elements 31, 31'. In addition, the material of the panel 2 can also contain at least one component with high thermal conductivity, for example, graphite.

[0033] 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).

[0034] 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.
