Definitions

  • the invention relates to a kit for air conditioning roofs or air conditioning facades, through which a heat exchange medium flows, with sheet metal webs and lines which are in heat-conducting contact therewith, the free ends of the lines each being connected to a flow collector or a return collector.
  • a sun-heated and cooled house has become known, the walls and the solar roof-supporting framework of which consists of a pipe system through which two heat exchange media flow.
  • the roof consists of two prefabricated metal sheets which are kept at a distance from one another and which accordingly form flow channels between them for a heat exchange medium.
  • the heat exchange medium is supplied through a strand located in the ridge of the roof.
  • the drainage is carried out by a strand, which is arranged on the eaves.
  • the construction Since the pipe system forms the actual basic structure of the house, the construction only makes sense for prefabricated houses with defined dimensions, which can be dismantled and reassembled elsewhere if necessary. However, the construction is difficult to adapt to houses that are to be built according to local building regulations in different architectural styles or in different sizes, if necessary in brick construction. In a similar manner, the construction is not suitable, for example, for covering larger factories or the like. It is also not possible to retrofit the construction into existing houses.
  • a solar roof has also become known, in which a pipe coil is arranged under a tile cover, which consists of long straight and corresponding semicircular curved parts.
  • the registration is based on the task of improving a kit for climate roofs or climate facades in such a way that the construction can be adapted to any houses or can be built into already finished houses.
  • the supply line for the heat exchange medium, the discharge line and preferably a pressure compensation line should be installed in the roof ridge or at the highest point of the roof or the area of the roof to be air-conditioned. Connected to these strands at a distance from one another, in the direction of the eaves or eaves, are hairpin-shaped curved lines. This ensures that the same flow pressure is applied to each of the lines, which results in a uniform flow of the heat exchange medium through the entire air conditioning roof. If at Dä If there is a pressure drop with increasing roof ridge with increasing distance from the connection point, a compensating line ensures the compensation of the pressure drop.
  • the eaves area remains free of inlets or outlets, so that any desired architectural solution can be selected there. In addition, damage caused by sliding snow, icing or the like is avoided in this way. This solution also enables perfect ventilation of the system. This structure also enables the air conditioning roof to be operated as a large-area evaporator.
  • regions of curvature are formed in the sheets or on the edges of the sheets.
  • the sheets are therefore not flat, but are deformed in such a way that they form contact surfaces for the pipes of the lines, so that a correspondingly good heat transfer is ensured.
  • the edges of the support plates can be bent at least semicircularly upwards and the edges of the cover plates semicircularly downwards.
  • the bent edge areas each encompass part of the pipe circumference.
  • the tubes also serve as holding means and connecting means for the sheets.
  • the collector running in the roof ridge or at the highest point of the roof or in the air-conditioned area of the roof consists of a strand 1 having three channels, to which a ridge cover plate 1 is assigned.
  • the channels of the strand 1 serve the inflow of a heat exchange medium, which consists of a liquid, such as water or brine, or also of a gas, e.g. Freezing, can exist, and the return of the heat exchange medium.
  • the third line is used for pressure equalization. If, for example, as shown in FIG. 1, the connection point for the supply and discharge of the heat exchange medium is on the right side, then the strand serving for the return of the heat exchange medium ends blindly, that is to say closed.
  • the two strands used to supply the heat exchange medium are connected to one another on the left-hand side. The return and supply of the heat exchange medium can, however, be interchanged. This results in a uniform flow resistance over the entire area to be air-conditioned.
  • hairpin-shaped lines 2 are provided, the legs of which are connected via hose pieces 3 and associated hose binders on the one hand to one of the collector supply channels and on the other hand to the blindly ending collector return channel of line 1.
  • the hairpin-shaped lines 2 can be kept ready in the kit in graded lengths, so that there is a corresponding adaptation to different roof sizes. Different thermal expansions between the pipes and the sheets and the collector are compensated for by the hose pieces 3.
  • the hairpin-shaped lines 2 can also consist of several pieces.
  • the point of curvature 4 can be connected to the straight legs of the lines 2 by connectors (not shown).
  • the point of curvature 4 can also be formed by a piece of hose.
  • the straight legs of the lines 2 can also consist of several pieces which are connected to one another for example by sleeves. Overall, the length of the hairpin-shaped lines 2 should be somewhat less than the distance from the strand 1 to be arranged on the ridge of the roof to the eaves 5 to be arranged at the end of the roof.
  • kits according to the invention can be attached directly to the substructure 6 of a roof, with an intermediate layer for noise insulation and sealing of the roof 6a, for example a cardboard layer or film, can be placed.
  • the kit according to the invention now also contains end support plates 7, further support plates 8, cover plates 9 and end cover plates 10.
  • edge regions 11 of the further support plates 8 are bent up. At one end 12 there is no arching by punching out. This area serves to nail the support plate 8 to the substructure 6. A further support plate 8 is then placed with its edge area on the area 12. The overlap accordingly results in a sealing of the nailing point; at the same time, the semicircular or three-quarter circular arch results in a more or less continuous receptacle for the straight web of the line 2.
  • the edge area at 13 can be left slightly longer, so that there is enough space remains for the inclusion of the point of curvature 4 of the line 2.
  • the curvature 4 extends over the space between the end support plates 7 and the adjacent end support plate.
  • a crossbar 14 is now arranged, which can be nailed onto the substructure 6 by the intermediate layer 6a.
  • Cover plates 9 are then pushed onto the straight webs of the line 2 and nailed to the crossbar 14, again an overlapping arrangement of the cover plates 9 can be selected so that the nail locations are covered.
  • the end cover plates 10 covering the area of curvature 4 of the line 2 are pushed on.
  • the end support plates 7 and the end cover plates 10 are bent over in a hook-shaped manner at their edges, so that a clean end at the edge of the eaves 5 results.
  • the edge regions of the support plates and cover plates are generally also semicircular or three-quarter circular, so that the cover plates and the support plates abut on the straight webs of line 2. This results in very good heat transfer from the support plates 8 and the cover plates 9 to the heat exchange medium flowing in the lines 2. Since in practice the width of the support plates 8 and the cover plates 9 is approximately 30 cm, this means that a maximum heat flow distance of 15 cm is not exceeded over the entire roof. Accordingly, the roof only cools by a few degrees Celsius compared to the ambient air temperature even when intensive heat is drawn.
  • a maximum cooling of the roof compared to the outside temperature of 2 ° C could be determined.
  • a bungalow with a roof area of around 200 m2 and a swimming pool with a water content of around 30 m3 will result in a shortening of the heating-up time from 1:10 to 1:30, even without using a heat pump compared to heating up the swimming pool the water surface striking solar radiation.
  • the straight webs of the lines 2 are connected to the corresponding channel of the line 1 by means of a piece of hose 3 which is fastened to the corresponding pipe socket by hose ties 15.
  • hose ties 15 By appropriate choice of the length of the hose section 3, a corresponding adjustment and compensation of differences in length can be carried out.
  • the lines 2 can also have a square, rectangular or polygonal cross-section, in which case the raised edges of the support plates and the cover plates are adapted to this cross-section.
  • the kit according to the invention requires a minimal space in the roof to accommodate the lines 2.
  • the increase of, for example, 1.5 cm in the roof produced with the kit according to the invention is of no importance whatsoever; on the contrary, the alternating elevation of the roof in the area of the cover plates 9 and deepening of the roof in the area of the support plates 8 results in a loosening of the roof structure, which is architecturally very appealing. From the outside, the roof is no different from a conventional tin roof. You also cannot see that the roof made with the kit is a climate roof.
  • the corresponding sheets can be made of copper or aluminum alloys. They can be kept in a correspondingly dark shade to increase the heat absorption capacity.
  • the sheets can also be replaced by extruded parts or plastic parts. In this case, ducts forming the lines 2 can be provided in the extruded parts.
  • the side edges of the sheet metal webs 19 are bent upward, as shown at 22. As shown in FIG. 7, the connection of two adjacent sheet metal webs takes place in that the raised edges 22 are flanged by means of a conventional continuous tool. This creates an absolutely waterproof roof seal.
  • FIG. 9 differs from the embodiment of FIG. 8 in that the sheet metal sheet 19 has semicircular or Q-shaped grooves 23 into which the tubes 21 are pressed.
  • the sheet metal sheet 19 has semicircular or Q-shaped grooves 23 into which the tubes 21 are pressed.
  • Fig. 10 shows a cross section of the eaves end.
  • the formwork boards 6 are nailed to the end of the beam structure supporting the roof in such a number that the narrow edge of the synthetic resin foam layer 20 of a component finds a corresponding abutment. In other words, you can make a corresponding length compensation for elements of staggered length if the distance from the ridge 1 a to the eaves 5 is specified.
  • the sheet metal sheet 19 expediently protrudes at the lower end by an amount of up to approximately 1 m, so that the slats 6 are covered.
  • the excess length can e.g. be cut off with a pair of tin snips and then the rest are crimped around the holder 24 for the eaves 5.
  • a modified embodiment, not shown, but also preferred compared to FIG. 10, is that the thickness of the slats is reduced by half, for example, compared to the thickness of the synthetic resin foam layer 20.
  • the synthetic resin foam layer 20 is then continued in half thickness to the end of the sheet web 19. Both in the embodiment shown in FIG.
  • a waterproof film made of plastic or metal is glued to the underside of the synthetic resin foam layer 20.
  • This process can of course also be carried out when the synthetic resin foam layer is foamed, as long as it is still adhesive due to its heating.
  • the film prevents moisture from penetrating into the synthetic resin layer from the covered space and being able to condense on the pipes 2, which are cooler than the surroundings, as condensation water, which could lead to a corrosion attack on the pipes 2.
  • the film is somewhat wider than the width of the synthetic resin foam layer 20, so that the edges can be turned up and glued to the side edge of the synthetic resin foam layer.
  • the embodiment described modified compared to FIG. 10 now has the advantage that the area lying above the slats 6 is also sealed and insulated.
  • the edge regions of a sheet metal web 25 are flanged over the full circumference of a tube 26.
  • This process takes place in several steps, e.g. by first bending the edge regions of the sheet metal sheet 25 vertically downwards, after inserting the tube 26, flanging is then carried out in tight contact with the tube 26 in two or three steps.
  • the embodiment offers the advantage that the tubes 26 are firmly connected to the sheets 25, that is to say it is a correspondingly integrated component which the roofer can lay without considering the tubes 26.
  • Another advantage lies in the improvement of the heat transfer from the sheets 25 to the tubes 26.
  • the illustrated embodiment can be moved to new roofs as well as to existing roofs, as shown in FIG. 13.
  • Support sheets 28, the side edges of which are bent up in a semicircular shape, and the components shown in FIGS. 12 and 13 are alternately laid on a roof skin or an insulating layer 27.
  • the attachment takes place via strips 29 and screws 30, a sealing ring 31 ensuring a corresponding sealing of the holes provided for the screws 30.
  • the sheets are stretched to the side, which results in a tight fit of the curved edge areas of the elements and a corresponding seal.
  • the overall optical impression is aimed at a roof-tile structure of the roof surface, on the one hand by striving for a dark red or brown color of the sheet metal elements by appropriate alloy additions or by treating the surface, and on the other hand by the sheet metal elements be deformed accordingly.
  • Practice has shown that the intended imitation effect can largely be achieved.
  • sheet metal coverings with the corresponding advantages of heat generation can also be created in settlements that otherwise have houses with brick coverings without disturbing the overall picture.
  • the dark tint improves heat recovery.
  • the deformation of the sheet metal sheets enables more uniform heat generation over a longer period, i.e. the surface is better adapted to the different angles of incidence of sunlight.
  • sheet metal sheets 32 or 33 are provided, the side edges of which are bent vertically upward at 34 or 35, so that the sheet metal sheets can be connected to one another by flanging, similarly as described in connection with FIG. 7.
  • the sheet web 32 is now pressed in at regular intervals at 36, as shown in FIG. 15.
  • the sheet web 33 has bulges 37, as shown in FIG. 16.
  • the deformation of the sheet metal webs 32 and 33 also improves the adhesion of an optionally provided synthetic resin layer 38.
  • the sheet webs 32 and 33 can, as shown in FIG. 14, be arched transversely to the longitudinal direction.
  • Corresponding tubes 39 can be attached to the abutting edges of the bulges.
