Description

[0001] The invention relates to a cooling / heating register for a suspended cooling / heating ceiling, which has a panel attached to parallel steel profiles that can be contacted by the cooling / heating register, wherein the cooling / heating register comprises at least: - several parallel linear copper pipe sections, which are connected in pairs at both ends of the cooling / heating register via connecting bends to form a pipe through which a fluid can flow, and which has at least one pipe connection at opposite ends of the cooling / heating register, - at least one heat-conducting profile section per copper pipe section, the cross-section of which has a wide base profile area that is flat on the underside for contact and heat transfer with the cladding, as well as an omega-shaped pipe receiving profile area connected to the base profile area, which encloses the linear copper pipe sections and - at least two crossbeam elements, each extending across the heat-conducting profile sections and the linear copper pipe sections and holding them in place,

[0002] A cooling / heating ceiling with such a cooling / heating register is described in the publication "Cooling and Heating Ceilings - VoglThermotop - Highly Efficient Energy Saving," accessed on February 10, 2026, at https: / / www.voql-deckensys-teme.de / dateien / pdfs / broschueren / de / SYS 0 0 DE 0424 Kuehl und Heizdecken VoglThermotop.pdf. By pressing linear copper pipe sections into pipe-receiving profile areas of a heat-conducting profile, heat transfer occurs via conduction over a large portion of the copper pipe's circumference, through which a temperature-controlled fluid flows. The wide base profile areas, in turn, facilitate heat transfer from the cooling / heating register to the cladding, also primarily via conduction. The cladding consists mainly of gypsum plasterboard. The installation sequence is chosen such that parallel steel profiles are first connected to and aligned with the building as longitudinal beams.The multiple cooling / heating coils are suspended within the steel profiles and interconnected via hoses or pipe sections, creating a single flow-through pipeline across the entire ceiling area to be heated / cooled. The pipeline is then tested for leaks. Finally, the cladding is attached to the underside of the steel profiles, with its upper surface resting against the underside of the wide, flat base sections of the heat exchanger profile. The connecting bends, which join adjacent linear copper pipe sections, extend beyond the heat exchanger profiles at the ends of the cooling / heating coils. This overhang is necessary, among other things, to allow access to the open ends of the copper pipe sections, which can be used as pipe connections, with crimping tools, enabling press fittings between adjacent cooling / heating coils.

[0003] These cooling / heating coils have generally proven effective. However, the various overhangs outside the heat exchanger profiles between cooling / heating coils arranged one behind the other result in a loss of usable surface area for heat transfer.

[0004] The so-called fine grid spacing, i.e., the spacing of the CD steel profiles that form a mounting grid for the sheathing, is quite narrow when using gypsum board for sheathing and is typically only 330, 417, or 440 mm. Subtracting the width of the steel profiles leaves a narrow gap of, for example, only about 270 mm, which is available for heat transfer through the cooling / heating coils. Therefore, optimizations are not possible in terms of width, but only by reducing gaps in the longitudinal direction.

[0005] The object of the invention is therefore to further develop a cooling / heating register of the type mentioned above in such a way that the gaps between cooling / heating registers arranged in a longitudinal direction are minimized.

[0006] This problem is solved by a cooling / heating register for a suspended cooling / heating ceiling with the features of claim 1, characterized by: - that an odd number of at least three parallel, linear copper tube sections are provided; - that the pipe connections are arranged at opposite ends of the cooling / heating register, in extension of the middle copper pipe section and above the level of the pipeline formed by the several copper pipe sections and connecting bends, - that the pipe connections each connect to copper pipe sections arranged off-center and - the connecting arcs run above the heat-conducting profile sections.

[0007] By having the connecting arcs run over or even rest on the heat-conducting profile sections, they can contribute to convective heat transfer.

[0008] The improvement of the invention is particularly evident in the increased contact area of ​​the heat-conducting profile sections with the cladding at both ends of the cooling / heating register. With a pipe pitch of, for example, 80 mm, the connecting bends have a radius of 40 mm, resulting in a total extension of 80 mm of the heat-conducting profile sections usable as contact surfaces with the cladding at both ends of the cooling / heating register. Based on a length of, for example, 1000 mm for the heat-conducting profile sections, this represents an increase in area of ​​8%.

[0009] A particular advantage is that the pipe connections are located at opposite ends of the cooling / heating coil, extending along the central copper pipe section and above the level of the pipework formed by the multiple copper pipe sections and connecting bends. This central arrangement of the pipe connections allows for any number of cooling / heating coils to be connected without having to define a specific end or end point.

[0010] Furthermore, the central placement allows easy access with a crimping tool to the pipe connection that protrudes beyond the heat-conducting profile sections. By positioning the pipe connection on a plane above the copper coil formed by the other copper pipe sections, connecting bends and pipe connections do not interfere with each other. This eliminates the need to offset the connecting bends axially from the ends of the heat-conducting profile sections; instead, they can be positioned directly at the edge, thus optimizing the use of the heat-conducting profile section's surface area.

[0011] It is preferred, particularly for small fine grating spacing, that three parallel, linear copper pipe sections are provided side by side, with an outer copper pipe section connected to the middle copper pipe section at each end via a connecting bend. This allows the cooling / heating register according to the invention to make good use of a narrow gap in the ceiling structure.

[0012] This results in a preferably mirror-symmetrical design of the cooling / heating register with respect to an axis of symmetry running through the central copper tube section. This allows the cooling / heating registers to be mounted and connected to each other in both possible longitudinal orientations.

[0013] For ease of manufacturing, it is intended that the pipe mounting profile areas of the heat-conducting profiles are at least partially removed at intersection points with the connecting bends.

[0014] However, it is also conceivable, for example through 3D printing, to continue the pipe mounting profile areas in the arc to the edge of the heat conducting profiles, so that the connecting arcs can also be thermally connected to the heat conducting profiles.

[0015] A preferred embodiment provides that at least one pipe connection is connected via an S-bend to an off-center copper pipe section, and that its end is aligned parallel to the copper pipe sections. The S-bend allows for a transition from the end of an off-center copper pipe section to the center and simultaneously to a higher plane.

[0016] Adjacent pipe connections of cooling / heating registers arranged one behind the other can be connected to each other by short intermediate pieces, so that the gaps in the longitudinal direction between adjacent cooling / heating registers are minimal.

[0017] The connection can be made by soldering or crimping, or by means of quick-release fasteners, which are commercially available under the name QSL, for example.

[0018] Alternatively, at least one pipe connection can be provided at the end of an elbow fitting, which connects to an off-center copper pipe section, with one leg of the elbow fitting oriented at a right angle to the copper pipe sections. This is advantageous when the cooling / heating registers arranged in series are to be interconnected via hose sections. The angled leg of the elbow fitting only needs to protrude slightly beyond the heat-conducting profiles, thereby further minimizing the gaps between the series of cooling / heating registers that are unusable for heat transfer to the cladding.

[0019] It is also advantageous to make further improvements to the truss elements. These are primarily U-shaped profiles made of sheet steel, divided into a central web through which or under which the pipe mounting profiles run, and a hook-shaped projection at both ends. Between the projection and the web, a recess is formed on each side to receive one leg of a C-shaped steel profile of the chilled / heated ceiling. This allows the chilled / heated register to be easily installed by simply hooking it onto the steel profiles of the ceiling structure using the hook-shaped projections. The connection between the truss elements and the copper pipe sections they intersect is preferably achieved without additional fasteners, solely through force or form fit.

[0020] In the form-fit connection, each copper pipe section has an undercut recess open to the lower edge of the web, in which the horseshoe-shaped pipe receiving profile area of ​​the heat-conducting profile section is held in a form-fit manner.

[0021] In the force-fit connection, the recesses are designed to be so narrow that the pipe mounting profile areas can be clamped there.

[0022] A cooling / heating ceiling equipped with the cooling / heating registers of the invention also comprises a covering which is attached to the parallel, horizontal steel profiles, wherein the base profile areas of the heat conducting profile sections rest on the top of the covering.

[0023] To ensure direct contact between the heat-conducting profile sections and the top surface of the sheathing, an advantageous embodiment involves matching the profile geometry of the ceiling substructure and the cooling / heating registers. If the steel profiles are designed as CD drywall profiles with the open side facing upwards, the crossbeam elements can be suspended from one leg of the profile, as described above. The distance between the underside of the base profile sections and the bottom of the recess in the crossbeam elements is greater than the profile height of the steel profile. This results in the cooling / heating register hanging low enough after the crossbeam elements are suspended that the underside of the base profile sections is lower than the underside of the steel profiles before the sheathing is installed.When the cladding is installed, it initially only rests against the base profiles of the cooling / heating registers, but not yet against the underside of the steel profiles of the ceiling structure. Screwing the cladding to the steel profiles raises the entire cooling / heating register, creating a permanently close, heat-conducting contact between the cladding and the base profiles of the cooling / heating register.

[0024] The hook projections of the traverse elements are only slightly raised relative to the steel profiles, but the positive-locking cross connection of the steel profiles via the traverse elements remains.

[0025] The invention is explained in more detail below with reference to the embodiment shown in the drawings. The figures show in detail: Fig. 1. A perspective view of one end of a cooling / heating register; Fig. 2A - 2C a cross-section through a cooling / heating ceiling in various assembly stages and Fig. 3 A top view of a cooling / heating register.

[0026] Fig. Figure 1 shows a perspective view of an end 21 of a cooling / heating register 100 of the invention. It consists of three parallel, linear copper tube sections 11, 12, 13, each of which is clamped in a tube receiving profile area 22 of a heat-conducting profile section 20. The heat-conducting profile section 20 also has wide, flat base profile areas 21 as a contact surface for heat conduction to the cladding.

[0027] The left outer copper pipe section 11 and the middle copper pipe section 12 are connected to each other via a 180° connecting bend 14, which runs entirely above the heat-conducting profile sections 20. Where the connecting bend 14 emerges from the central axis of one of the heat-conducting profile sections 20, the pipe receiving profile area 22 is excluded.

[0028] The right outer copper pipe section 13 continues in an S-bend 16, which extends inwards to the central axis of the middle copper pipe section 12 and also to above the connecting bend 14. The pipe receiving profile area 22 is excluded where the S-bend 16 protrudes from the central axis of the heat-conducting profile section 20. Thus, the pipe connection 18 is aligned with the middle copper pipe section 12, but above it. It alone projects beyond the end of the heat-conducting profile section 20 and can be designed for press, solder, or push-fit connection with another, adjacent cooling / heating register 100.

[0029] Fig. Figure 3 shows a complete cooling / heating register 100 from above, which is suspended by its crossbeam elements 30 in CD steel profiles 201, 202 of the ceiling structure. The dashed lines indicate the greatest longitudinal extent of the cooling / heating register 100, and it can be seen that in the invention the free area between the line and the end of the heat-conducting profiles 20, which is not usable for heat transfer, is small.

[0030] In addition to the already at Fig. At the lower end 101 of the connecting bend 14 described in section 1, a further connecting bend 15 is provided at the upper end 102 to connect the ends of the middle and right copper pipe sections 12, 13. An S-bend 17 leads from the left copper pipe section 11 to the central axis and to above the middle copper pipe section 12. A further pipe connection 19 is provided at the end of the S-bend.

[0031] Fig. Figure 2A shows a cross-section through a chilled / heated ceiling 200 in a first step of the installation process. The CD steel profiles 201, 202 are already installed on the building side. The chilled / heated register 100 is connected to them via its crossbeam elements 30. The crossbeam elements 30 each have a hook-shaped projection 33 at their two ends, with a recess 32 between the projection 33 and the web 31. The leg of the CD steel profiles 201, 202 facing the chilled / heated register 100 is received in the recess 32. The recess 32 is designed to be deep enough so that, in the suspended position, according to Fig. 2A the respective underside of the base profile areas 21 is located slightly below the lower edge of the CD steel profiles 201, 202. In the assembly step, the cladding 203 is brought into position from below last.

[0032] How Fig.Figure 2B shows that the upper side of the sheathing 203 is initially attached to the base profile areas 21, but not yet to the underside of the CD steel profiles 201, 202. In this position, the sheathing 203 is screwed to the CD steel profiles 201, 202.

[0033] As the screw connection is tightened, the sheathing 203 is pressed against the CD steel profiles 201, 202, which at the same time raises the cooling / heating register 100 slightly relative to the CD steel profiles 201, 202, while the hook connection via the projections 32 still exists, so that due to the weight of the cooling / heating register 100 resting on the sheathing 203, permanent contact between the base profile areas 21 and the top of the sheathing 203 is ensured.
