Definitions

  • the invention relates to a cooling element and a cooling ceiling, as they are used for the air conditioning of rooms.
  • cooling elements which includes a meandering example bent pipe for passing a cooling fluid, usually water.
  • the tube runs over a rectangular flat, designed as a perforated plate ceiling plate, with its straight sections are on heat conduction in good heat conducting contact.
  • Such cooling elements may be composed to a ceiling plate.
  • the heat-conducting rails can be glued to the ceiling panel ( EP 0 769 659 A1 ) or by magnets ( EP 0 406 476 A2 ). Because of the good heat-conducting contact and the ceiling plate is effectively cooled and this in turn flowing through them or along her flowing air, so that a high cooling performance is achieved.
  • the production of a good heat-conducting connection between the pipe and the ceiling slab is always associated with some effort, especially if the production of large-area contact is not readily possible because the top of the ceiling slab, such as a slab of expanded metal, is uneven.
  • the invention is based on the object to provide a generic cooling element, the cooling capacity without tight heat-conducting contact with an underlying ceiling plate, even without the use of such, is sufficiently large, without the set by various standards limits approximately in terms of permissible flow rates would be exceeded.
  • the cooling element 1 comprises a tube arrangement for the passage of a cooling fluid, preferably cold water, which consists of three subassemblies 2, 3, 4 arranged one above the other. They are each lying in a horizontal plane meander of copper, steel or aluminum tube, the projection of which in dashed lines in Fig. 1 indicated base surface of the cooling element 1 the same in each case approximately from one edge to the other to a certain part, with the exception of larger spaces , fills out.
  • a ceiling plate 5 is arranged, which may be formed as a perforated plate or as expanded metal plate.
  • the sub-assemblies 2-4 are connected in parallel with a supply line and a discharge (not shown) for the cooling fluid. But they can also be connected in series. They are of the same design and arranged at a distance one above the other, that is, perpendicularly spaced from each other, resulting in an unobstructed air flow allowed by the cooling element 1, so that an intensive convective cooling of the surrounding air takes place.
  • the arrangement is chosen so that their total projection on the base area as large as possible, i. the overlap of the vertical projections of the subassemblies 2, 3, 4 is low, if possible at most 40% and preferably not greater than 20 or even 10% of the total projection area of the cooling element 1.
  • the second subassembly 3 with respect to the first subassembly 2 by 90 ° rotated and the third sub-assembly 4 relative to the second sub-assembly 3 also, while the first sub-assembly 2 is laterally offset. Due to the large projection surface, the cooling element 1 is in intensive radiation exchange with the ceiling plate 5 and through their openings through with the underlying space, so that the convective cooling is effectively supplemented by radiation cooling.
  • the support 6 is formed as a closed circumferential jacket 7 of a square prism (FIG. 3-5), which is punched and bent, for example, from sheet metal, preferably from sheet steel.
  • the shell On opposite parallel walls 8a, b, the shell has two aligned, semicircular, vertical, short slots 9a, b, 10a, b, which emanate from the upper and lower edges of the walls 8a, b, respectively, where they extend from Partially deflectable snap projections 11 are partially surmounted. They are laterally offset from each other.
  • the slots 9a, b respectively serve for receiving pipe sections of the third subassembly 4, the slots 12a, b for receiving those of the second subassembly 3 and the slots 10a, b of those of the first subassembly 2.
  • the snap projections 11 are the pipe sections respectively snap-locked and securely fixed both in terms of their height and their direction by the stable support 6.
  • the support (FIG. 6) comprises a vertical bolt 13, the upper end of which can be anchored to a room ceiling. It can be provided with a continuous thread and carries three spaced superimposed, laterally horizontally projecting tabs 14, 15, 16 made of sheet steel, which are each bent at the end down so that they form upwardly open receptacles 17 for pipe sections, in which are snap lockable.
  • the tabs 14, 15, 16 may be screwed or soldered to the bolt 13. Immediately superimposed tabs are each rotated by 90 ° in the same sense against each other.
  • Cooling ceilings according to the invention can comprise a multiplicity of cooling elements arranged according to the invention in a grid below a ceiling, as well as air-permeable, but otherwise largely arbitrarily formed ceiling panels which can be arranged in a corresponding grid or, because of the decoupling of the cooling elements, also another grid.
  • the ceiling tiles always have a predominantly aesthetic significance and are not absolutely necessary for the cooling function. Incidentally, use of the elements described for heating purposes is not excluded, although their specific advantages in this case come less to bear.
