Definitions

  • the present invention relates to a false ceiling made of a plurality of suspended metal ceiling elements.
  • metal ceilings it is possible to design them as chilled ceilings by arranging cooling elements in the space between the metal ceiling and the actual room ceiling.
  • cooling elements With these known constructions, however, only a relatively poor cooling performance can be achieved, since the heat transfer from the room to the cooling elements is not optimal.
  • the space in the ceiling is mainly filled with lines for a cooling medium and cooling elements, leaving little space for other installations.
  • the purpose of the present invention is now to create a room ceiling which can be used to form a cooling ceiling with little effort, which is suitable for dissipating at least medium heat loads, is largely standardized, is easy to install and service and is also inexpensive.
  • the room ceiling which consists of a plurality of suspended metallic ceiling elements, is characterized in accordance with the invention in that, in order to form a cooling ceiling, at least one pipe for carrying a cooling medium is fixedly arranged in at least part of the ceiling elements on the rear side thereof, that the pipe in Area of an element end has an inlet and an outlet, the inlet and outlet being connected via a hose line to a supply or return line for cooling medium mounted above the elements and independently of them.
  • the hose connections are preferably designed as separating couplings, in which couplings automatically acting closing valves can be formed. In this case, there is no need to empty the cooling elements or the Cooling system, if a repair or the like is to be made.
  • the pipe which forms the actual cooling element can consist of at least two pipe sections which extend over the length of a ceiling element, the pipe ends not serving as inlet or outlet being connected to one another by means of a hose line, preferably likewise by means of separating couplings. Thanks to this construction, the ceiling elements can be connected to the supply and return lines at any end.
  • the pipes forming the cooling elements are preferably each provided with a foot part which extends over their length and which can rest against the inner wall of the corresponding ceiling element and at the same time serves to fasten it to the latter.
  • the attachment is preferably carried out by means of a warm or cold conductive adhesive.
  • Fig. 1 of the drawing shows a metallic ceiling element 1, the underside of the plate 2 e.g. can be perforated to form a sound absorbing ceiling.
  • An acoustic fleece can be arranged (glued in) on the back of the panel.
  • the pipelines consist, for example, of drawn profiles with the cross-sectional shape shown, foot 8 and 9 in particular serving to come into close contact with the plate, so that good heat transfer is ensured.
  • the pipes 6, 7 are e.g. glued to the plate edges 4, 5 by means of a heat or cold conductive adhesive.
  • This arrangement also has the advantage, among other things, that standardized plates can still be adjusted to a specific length on the construction site by cutting the element to the desired length together with the pipes 6, 7.
  • the shape of the metallic piping shown ensures good heat transfer to the cooling medium: On the one hand, heat reaches the pipe and thus the cooling medium via the feet 8, 9 in contact with the plate, and on the other hand the pipe has a relatively large surface area, which can dissipate heat from the ceiling cavity to the cooling medium.
  • Fig. 2 shows from above a section of a cooling ceiling, which consists of ceiling elements 1 of the type described above.
  • the built-in cooling elements in the form of the pipes 6, 7 extend to near the plate ends.
  • Connection flanges 10 (see also FIG. 4) are screwed onto these ends, so that pieces of hose can be attached to these flanges (see description below).
  • the two pipes 6, 7 are connected to one another at one end of the plate via a piece of hose 11.
  • the pipeline 6 is connected via the hose section 12 to the stationary supply line 13 for the cooling medium, preferably via self-closing plug-in couplings of a known type.
  • the hoses 12 can also be connected to the pipes 6 via such couplings or via conventional hose connections.
  • the pipeline 7 is connected to the coolant return line 15 at the end mentioned via a hose line 14, likewise via automatically closing plug-in couplings of a known type.
  • FIG. 3 of the drawing again shows a schematic section through a ceiling element, it being apparent that both the supply and return lines 13 and 15 are arranged in the ceiling cavity above the ceiling elements.
  • a ceiling element can be easily hung or can be dismantled and the connections between the hoses and the supply and return lines can be released in the simplest way.
  • every ceiling element with integrated cooling elements can be dismantled in the simplest way, for example to be revised.
  • the tube pieces being able to be fixedly attached to the pipes 6, 7 of the ceiling element, so that only their free end is to be connected to the stationary lines via a plug-in coupling.
  • the pipeline profiles 6, 7 are designed such that the connecting nipples 10 can be connected to the pipelines 6, 7 in a simple manner by means of two screws.
  • FIG. 4 shows such a connection nipple 10 in a side view, the laterally projecting arms 16, 17 being dimensioned such that an overlap with the corresponding parts 18, 19 of the pipes 6, 7 is readily possible.
  • the hose lines 11, 12 and 14 are preferably made of flexible rubber, these rubber hoses e.g. can be metal coated.
