Definitions

  • the invention relates to a cooling ceiling element made of a sheet metal plate and a Pipe that is attached to one side of the sheet metal plate and is in one plane extends over their base area at regular intervals, with intervals mutually extending, straight lines of the pipeline in other Corresponding beads of the sheet metal plate are recessed.
  • Such well-known chilled ceiling elements become chilled ceilings produced, which have the task, preferably in connection with a Discharge source ventilation in the area around people from cooling loads.
  • ceilings are completely or partially covered with cold water Heat exchangers occupied, which the ceiling temperature below room temperature lower and hold, so that such ceilings as chilled ceilings and used heat exchanger referred to as chilled ceiling elements.
  • room ceilings such as open grid ceilings, directional metal corner ceilings or closed plaster ceilings, which also as Acoustic ceilings can be installed are known. Because ceilings In this way, chilled ceiling elements should be of great architectural importance be that the execution of the ceilings without significant restriction of the Allow design and geometry.
  • the known room ceilings are based on an arrangement of a plurality of pipelines between a distributor pipe and a collector pipe. This parallel connection of Piping is complex and expensive to manufacture, leading to one uneven loading of the pipelines and especially often too Leaks due to the large number of connections required.
  • the efficiency of a cooling ceiling element described at the outset and thus The overall efficiency of the cooling ceiling is significantly influenced by the Type of connection between the sheet metal plate and the pipeline.
  • Holding profiles of various embodiments are generally known, on the one hand are to be fastened to the sheet metal plate and, on the other hand, sections of the pipeline clasp.
  • the attachment of a large number of Holding profiles on a sheet metal plate is labor-intensive is limited the heat transfer to the partial surfaces of the pipeline, which with the sheet metal plate brought into contact directly or at least indirectly via the holding profiles become.
  • the invention has for its object a cooling ceiling element of the beginning type described so that it is a large area immediate Distinguishes connection between the sheet metal plate and the pipeline, is easy to manufacture in series and with little effort can be varied at the place of use, especially the cold water Piping including the pipe spacing depends on the respective requirements adjust.
  • 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 in such a way 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 in the longitudinal and transverse directions to the beads to the dimensions required in each case and can be equipped with a pipeline in the thus cut state. So prepared, the chilled ceiling element, e.g. B. on a grid ceiling, simply placed on pre-assembled cross consoles or, for. B. with a closed plaster ceiling, can be fixed against the plaster base plate.
  • a cladding plate extends at least over the base area of the sheet metal plate and blocks the opening cross section of all the beads.
  • the beads have an omega shape Cross section on, so that the pipe can be pressed into the beads and under Clamping force is held in it.
  • the straight lines are the pipeline outside the beads provided in the sheet metal plate arcuate pipe pieces connected so that the pipe overall meandering.
  • this preferably also extends over the arcuate pipe pieces and also covers them so that also whose connections are covered with.
  • an embodiment of the invention provides that the sheet metal plate outside the beads with perforations evenly distributed over the base is provided so that sound waves can penetrate into the ceiling cavity and there be absorbed.
  • the cooling ceiling element consists essentially of a sheet metal plate 1 and one Pipeline 2 and a cladding plate 3 which is not absolutely necessary.
  • the sheet metal plate 1 consists of an aluminum sheet, which at intervals over its Has wide ⁇ -shaped beads that extend continuously over the length of the sheet metal plate 1 extend.
  • the pipe 2 consists of flexible copper pipe or mild steel pipe or flexible, diffusion-proof plastic tube and has straight sections 5 that are embedded in the beads 4 and via curved pipe sections 6 are connected to each other outside the base of the sheet metal plate 1 so that the pipeline 2 is meandering overall and has end pieces 7, 8 in conventionally to a supply or return line, not shown cold water-carrying main line can be connected.
  • the cladding plate 3 which in a conventional manner with the sheet metal plate can be connected, also consists of aluminum and connects to their Long sides flush with the sheet metal plate 1, while over the transverse sides protrudes. With the cladding plate 3 are therefore the arcuate pipe pieces 6, and the end pieces 7 and 8 with their connections concealable.
  • the meandering pipeline 2 can be in the beads of the sheet metal plate Simply clip in 1 if the beads 4, as in the exemplary embodiments shown, a cross-sectional contour with a slightly smaller opening width have as the outer diameter of the pipeline 2nd
  • Clamping brackets which press the cooling element onto the ceiling plate 9.
  • the bias of this bracket must be very precise on the deflection of the Ceiling plate 9 must be matched to the existing deflection not to enlarge.
  • this preload depends on the width of the ceiling tile 9 must be varied and this clamp due to the different Manufacturing-specific versions of edging of the ceiling tile 9 need a specific connecting element to the ceiling panel 9. Thereby there are considerable costs for preliminary tests with regard to preload and warehousing.
  • Another disadvantage is that in project processing the special version of the ceiling plate 9 must be known.
  • the cladding panel 3 shown in Figures 1 and 2 is in this embodiment not mandatory.
  • the bead 4 is dimensioned so that between the copper tube 5 and the ceiling plate 9 results in a cavity 10, which a 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 prefabrication become.
  • the connection to the ceiling slab is then made at the construction site 9, e.g. by removing a protective strip from the adhesive material 11.
  • the accommodation of the adhesive material 11 in the bead 4 has the advantage that none additional material gets between the sheet metal plate 1 and the ceiling plate 9, which worsens the heat transfer.
  • adhesive material 11 with poor thermal conductivity can also be used become. If adhesive material 11 with good thermal conductivity is used, the result is in this respect an improvement, since compared to a linear support of the pipeline 2 A wide-area transmission area is created.
  • ceiling panels 9 with continuous Perforation will be a tissue-like tape to insert a passage avoid pasty glue through the perforation of the ceiling tile.
  • a pasty adhesive can also be used be, with at least two holes 13 then being provided in the bead 12 are.
  • 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 the control, whether the bead 12 is filled.
  • FIG. 4 Another mounting option is shown in Figure 4.
  • the sheet metal plate 1 which is to be connected to the ceiling plate 9, tabs 14 through three-sided free cutting generated.
  • a double-sided adhesive tape 15 On each tab 14 on the ceiling plate 9 facing side applied a double-sided adhesive tape 15. Because in the 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 pressed onto the ceiling plate 9. This will help with the Gluing even a tensile stress through the tab 14, which is in its original position wants to spring back, generates and improves the contact pressure.
  • FIG. 6 shows an embodiment in which an adhesive connection is used waived and a purely mechanical connection is selected.
  • the Sheet metal plate 1 provided in the edge region with a double edging 19, the horizontal end engages under an edge 20 of the ceiling plate 9.
  • manufacturing tolerances are compensated for and achieved at the same time pressing the cooling element onto the ceiling plate 9.
