Definitions

  • the invention relates to a cooling ceiling element made of a sheet metal plate and a pipeline, which is fastened on one side of the sheet metal plate and extends in a plane in a meandering manner over its base area at regular intervals.
  • Cooling ceilings are produced from such well-known cooling ceiling elements, which have the task of dissipating cooling loads occurring in connection with a source ventilation in the area where people are staying.
  • room ceilings are completely or partially covered with cold water-carrying heat exchangers, which lower and maintain the ceiling temperature below room temperature, so that such room ceilings are referred to as chilled ceilings and the heat exchangers used as chilled ceiling elements.
  • room ceilings such as open grid ceilings, directional metal angular ceilings or closed plaster ceilings, which can also be installed as acoustic ceilings, are known. Since ceilings have an architecturally high priority, chilled ceiling elements should be designed in such a way that they allow the execution of the ceilings without significantly restricting the design and geometry.
  • the efficiency of a cooling ceiling element described at the outset and thus also the efficiency of the cooling ceiling as a whole is significantly influenced by the manner of the connection between the sheet metal plate and the pipeline.
  • retaining profiles of the most varied of embodiments are generally known, which on the one hand are to be fastened to the sheet metal plate and on the other hand clasp sections of the pipeline.
  • the attachment of a large number of holding profiles to a sheet metal plate is labor intensive the heat transfer to the partial surfaces of the pipeline, which are brought into contact with the sheet metal plate directly or at least indirectly via the holding profiles.
  • the invention has for its object to provide a chilled ceiling element of the type described in such a way that it is characterized by a large-area direct connection between the sheet metal plate and the pipeline, is simple to manufacture in series and can also be varied at the place of use with little effort, whereby In particular, the cold water piping including the pipe spacing can be adapted to the respective requirements.
  • the arrangement according to the invention of sections of the pipeline in beads of the sheet metal plate results in a large-area contact between the pipeline and the sheet metal plate, without having to rely on specially designed holding profiles, tensioning elements and similar aids. Instead, it is sufficient to profile the sheet metal plate such that beads are preferably provided over its width at regular intervals, which beads extend continuously over the length of the sheet metal plate.
  • the density of the straight lines of the pipeline can be varied in such a way that a line of the pipeline is laid either through each bead or only through every second, third or any subsequent bead.
  • the sheet metal plate is braced, which has an effect in particular about an axis perpendicular to the longitudinal extension of the bead.
  • the number of fastening points on the cooling ceiling element can be reduced without having to fear significant deflection.
  • the sheet metal plate can be reduced to the required dimensions in the longitudinal and transverse directions to the beads and cut to size Condition with a pipeline. So prepared, the chilled ceiling element, e.g. B. on a grid ceiling, simply placed on pre-assembled cross brackets or, for. B. with a closed plaster ceiling, be fixed against the plaster base plate.
  • the ends of the pipeline are dimensioned so long that a connection to a main pipeline can be established using commercially available connections.
  • the beads have an omega-shaped cross section, so that the pipeline can be pressed into the beads and is held therein under clamping force.
  • a cladding plate can also be used, which extends at least over the base area of the sheet metal plate and blocks the opening cross section of all the beads.
  • the straightened sections of the pipeline are connected to one another outside the beads provided in the sheet metal plate via arcuate pipeline pieces so that the pipeline is meandering overall.
  • this preferably also extends over the arcuate pipe pieces and also covers them so that their connections are also covered.
  • an embodiment of the invention provides that the sheet metal plate is provided outside the beads with perforations evenly distributed over the base, so that sound waves can penetrate into the ceiling cavity and be absorbed there.
  • the cooling ceiling element essentially consists of a sheet metal plate 1 and a pipeline 2 as well as a cladding plate 3 which is not absolutely necessary.
  • the sheet metal plate 1 consists of an aluminum sheet which has ⁇ -shaped beads at intervals across its width, which extend continuously over the length of the sheet metal plate 1.
  • the pipe 2 consists of flexible copper pipe or mild steel pipe or of flexible, diffusion-tight plastic pipe and has straight sections 5, which are embedded in the beads 4 and are connected via arcuate pipe pieces 6 outside the base of the sheet metal plate 1 so that the pipe 2 as a whole runs meandering and can be connected in a conventional manner with end pieces 7, 8 to a supply or return line, not shown, of a cold water-carrying main line.
  • the cladding plate 3 which can be connected in a conventional manner to the sheet metal plate, is also made of aluminum and is flush on its long sides with the sheet metal plate 1, while it projects over the transverse sides thereof. With the cladding plate 3, the arcuate pipe pieces 6 and the end pieces 7 and 8 with their connections are therefore also concealable.
  • the meandering pipe 2 can be simply clipped into the beads of the sheet metal plate 1, provided that the beads 4, as shown in the exemplary embodiments, have a cross-sectional contour with a slightly smaller opening width than the outside diameter of the pipe 2.
  • cooling elements are inserted into commercially available ceiling panels (e.g. metallic long-field cassettes)
  • good contact between the sheet metal plate 1 of the cooling element and a respective ceiling panel 9 shown in FIGS. 3 to 7 is necessary in order to achieve a high cooling capacity.
  • This is often difficult in practice, since the ceiling panel 9 already has a deflection due to its own weight and this should generally not be further enlarged for optical reasons.
  • Clamping brackets which press the cooling element onto the ceiling plate 9.
  • the pretension of these brackets must, however, be matched very precisely to the deflection of the ceiling plate 9 in order not to increase the already existing deflection.
  • this pretension must be varied depending on the width of the ceiling panel 9 and these clamps require a specific connecting element to the ceiling panel 9 due to the different manufacturing-specific designs of edging the ceiling panel 9. This results in considerable costs for preliminary tests with regard to preloading and for storage.
  • Another disadvantage is that the special design of the ceiling plate 9 must be known in project processing.
  • the cladding panel 3 shown in Figures 1 and 2 is not required in this embodiment.
  • the bead 4 is dimensioned so that there is a cavity 10 between the copper tube 5 and the ceiling plate 9, which holds an elastic adhesive material 11, preferably with good thermal conductivity. This can be applied in pasty form or as an adhesive tape.
  • the adhesive material 11 can already be applied to the cooling element during the prefabrication.
  • the connection to the ceiling plate 9 is then made at the construction site, for example by pulling off a protective strip from the adhesive material 11.
  • the accommodation of the adhesive material 11 in the bead 4 has the advantage that no additional material gets between the sheet metal plate 1 and the ceiling plate 9, which deteriorates the heat transfer.
  • adhesive material 11 with poor thermal conductivity can also be used. If adhesive material 11 with good thermal conductivity is used, there is an improvement since a broad-area transfer surface is created compared to a linear support of the pipeline 2.
  • the stability of the overall component is improved by the gluing of the cooling element to the ceiling plate 9 and in particular the deflection of the ceiling plate 9 itself is reduced.
  • the adhesive material 11 ' can also be accommodated in a separate bead 12.
  • a fabric-like adhesive strip will have to be used in order to prevent pasty adhesive from passing through the perforation of the ceiling panel.
  • a pasty adhesive can also be used, in which case there are at least two bores 13 in the bead 12.
  • the pasty adhesive material 11 ' is pressed into one of these bores 13.
  • the other bore 13 serves for the exit of the adhesive material 11 'or for checking whether the bead 12 is filled.
  • FIG. 4 A further fastening possibility is shown in FIG. 4.
  • tabs 14 are produced from the sheet metal plate 1, which is to be connected to the ceiling plate 9, by three-sided punching out.
  • On each tab 14 becomes the ceiling plate 9 facing side applied a double-sided adhesive tape 15. Since, as a rule, the cooling elements are only connected to the ceiling panels at the construction site, the protective film is only removed from the underside of the band 15 here and the tab 14 is pressed onto the ceiling panel 9.
  • the adhesive even creates a tensile stress through the tab 14, which wants to spring back into its original position, and improves the contact pressure.
  • connection of the ceiling plate 9 to the sheet metal plate 1 is carried out by introducing a connecting element, consisting of a round spring steel plate 17 with adhesive layer 18, into a recess 16 in the sheet metal plate 1.
  • a connecting element consisting of a round spring steel plate 17 with adhesive layer 18, into a recess 16 in the sheet metal plate 1.
  • the sheet metal plate 1 and thus the cooling element are pressed onto the ceiling plate 9 by the resilient edge regions.
  • FIG. 6 shows an embodiment in which an adhesive connection is dispensed with and a purely mechanical connection is selected.
  • the sheet metal plate 1 is provided in the edge region with a double edging 19, the horizontal end of which engages under an edging 20 of the ceiling plate 9. Manufacturing tolerances are compensated for by an elastic intermediate layer 21 and, at the same time, the cooling element is pressed onto the ceiling plate 9.
  • a sagging of the ceiling plate 9 is counteracted by a two-part adjusting bracket 22 or 22 ′, which engages with grooves in the upper horizontal edging of the ceiling panel 9.
  • the force is adjustable by means of the telescopically adjustable adjusting bracket 22 or 22 ', bores 23 being used to receive a pin for the purpose of locking.
  • springs 24 can be pressed by springs 24 and thus good thermal contact between the cooling element and the ceiling plate 9 can be achieved.
