Kit for climate roofs or climate facades

The invention relates to a kit for climate roofs or climate facades, whereby under a "climate roof" or a "climate facade" is a roof or a roof through which a heat exchange medium flows Facade is to be understood.

^{C / Li} 809885/0521

The heat exchange medium flowing through the roof can be used for a climate roof without changes to the roof itself various purposes are used, e.g. B. for the following:

a) Cooling of makeshift buildings, e.g. B. when used in hot disaster areas, Cooling of factories, hospitals and other buildings where the space directly under the roof is exploited;

b) heat recovery from the roof, e.g. B. for heating swimming pools, where z. B. a shortening of the heating time of a swimming pool in a normal house by a factor of 1: 10 results;

c) Extraction of heat from incident solar radiation and from the air sweeping over the roof by means of a heat pump, e.g. for heating the domestic water or for space heating purposes down to e.g. minus 5 ° C or minus 10 ° C outside temperature;

d) Heating of the ground below the building or other Soil parts in the summer months for the purpose of obtaining heat by means of a heat pump from the ground in the winter months;

e) Automatic snow thawing in snowy areas through heating the roof by means of the heat exchange medium;

f) Large-scale evaporation in the climate roof as part of a heat pump system;

g) Large-area heat dissipation in the climate roof as part of a cooling system.

809885/0521

The heat recovery from groundwater has increased as a result of the risk of Groundwater pollution proved problematic. The recovery of heat from sea water requires systems that are easily polluted can, must extend at great depths and from can easily be damaged by shipping. In the case of heat recovery from river water, apart from the risk of pollution, the Risk of damage from floating tree trunks or the like. When generating heat from collectors set up in the open problems arise with regard to the impairment of the landscape and the loss of agriculturally usable land. For this Basically, the energy problems concentrate on the recovery of heat from roofs. The problem arises of creating a kit, which can be universally adapted to roofs of different dimensions and which does not conflict with other required structural elements, z. B. the eaves or the like., Arise. Furthermore, it is difficult to achieve a uniform flow of the with the known climate roofs Ensure heat exchange medium over the entire, often very large roof area.

The invention is accordingly based on the object of a kit For climate roofs or facades to propose the one with a single one, located in the roof ridge or at the highest point of the climate surface Connection point for the heat exchange medium gets along and in which the above-mentioned difficulties do not occur.

The kit for climate roofs according to the invention consists of:

a) one at the roof ridge or at the highest point of the roof or the To be air-conditioned area to be arranged strand for the inlet and outlet of the heat exchange medium, which is essentially extends horizontally and transversely to the roof slope;

⁸³⁷⁴ 809885/0521

b) hairpin-shaped lines spaced from each other be connected to the string and which extend from the roof ridge perpendicularly away from the string in the direction of the eaves, wherein the point of curvature is preferably directed towards the eaves;

c) support plates, which form overlapping tracks that are spaced run from each other from the ridge to the eaves or along the facade;

d) Cover plates, which form the space between the support plates bridge, and their surfaces at a distance of the surfaces of the support plates are arranged, which is approximately the diameter of the hairpin-shaped lines plus the Corresponds to the thickness of the cover plates and preferably

e) End cover plates, which shape the curvature of the hairpin cover formed lines, and the staggered arrangement of the support plates and the cover plates on the eaves edge equalize the roof,

wherein the support plates and / or the cover plates are spacing and holding means have, which on the one hand enable the heat transfer from the metal sheets to the hairpin-shaped lines and which on the other hand, automatically secure the mentioned distance between the surfaces of the cover plates from the support plates.

The invention is therefore based on the consideration that the supply line for the heat exchange medium, the discharge line and preferably a pressure equalization line in the roof ridge or to the highest point of the roof or the area of the

8374 809885/0521

■ y-1

Roof is being laid. Attached to these strands are spaced from each other hairpin-shaped extending in the direction of the eaves or the eaves bent lines connected. This ensures that the same flow pressure is applied to each of the lines becomes, resulting in a uniform flow of the heat exchange medium through the entire climate roof. If on roofs with a longer ridge there is a pressure drop with increasing distance of occurs at the connection point, a compensation line compensates for the pressure drop. The eaves area remains free of inlets or outlets, so that any desired architectural solution can be chosen there. In addition, this way damage is caused by slipping snow, icing or the like. Avoided. This solution also enables the system to be properly vented. This structure also enables the air-conditioned roof to be operated as a large-area evaporator.

According to a preferred embodiment, the spacing and holding means are formed by areas of curvature in the metal sheets or on the Edges of the sheets formed. The support plates and the cover plates are therefore not flat, but rather deformed in such a way that they contact surfaces Form for the pipes of the lines, so that a correspondingly good heat transfer is ensured. In particular, the edges of the support plates be bent at least in a semicircle upwards and the edges of the cover plates in a semicircle downwards. The bent ones Edge areas each encompass a part of the pipe circumference.

Further preferred embodiments of the invention emerge from FIG the subclaims.

On the drawings is a preferred embodiment of the object of the invention shown. Show it:

Fig. 1 is a perspective view of the assembly of the kit according to the invention on a roof;

2 shows a plan view of a support plate; 3 shows a cross section along the line ΠΙ-ΠΙ; 4 shows the end of an end support plate;

5 is a perspective view of an end cover plate from below;

6 shows a cross section through the connection point of the pipeline with the strand running in the roof ridge and

7 shows the connection of tubes which have a helical screw on their outside.

In the embodiment shown, there is the ridge or in the roof Collectors running at the highest point of the roof or in the air-conditioned area of the roof from a three-channel system Line 1, which is assigned a ridge cover plate la. The three channels of strand 1 are used for the inflow of a heat exchange medium, which consists of a liquid, such as water or brine, or from a gas, e.g. B. Frigen, as well as the return of the Heat exchange medium. The third line is used to equalize the pressure. If, for example, as shown in FIG. 1, the Connection point for the supply and discharge of the heat exchange

⁸³⁷⁴ 809885/0521

diums is on the right side, then ends on the left side of the The line serving for the return of the heat exchange medium is blind and closed. The two for the supply of the heat exchange medium serving strands are connected to each other on the left side. The return and supply of the heat exchange medium can, however be swapped. This results in a uniform flow resistance over the entire surface to be air-conditioned.

Furthermore, lines 2 designed in the shape of hairpins are provided, their legs via hose pieces 3 and associated hose ties on the one hand with one of the collector flow channels and on the other hand with the blind-ending collector return channel of line 1 are connected. The hairpin-shaped lines 2 can be graduated in the kit Lengths to be kept ready so that there is a corresponding adaptation to different roof sizes. Different thermal expansions! between the pipes and the metal sheets as well as the collector are compensated for by the hose pieces 3. The hairpin-shaped formed lines 2 can also consist of several pieces. For example, the point of curvature 4 can by not shown Connector to be connected to the straight legs of the lines 2. The point of curvature 4 can also be formed by a piece of hose will. The straight legs of the lines 2 can also consist of several pieces, which are connected, for example, by sleeves will. Overall, the length of the hairpin-shaped lines 2 should be slightly less than the distance from the am Ridge of the roof to be arranged strand 1 to the eaves to be arranged at the end of the roof 5.

A particular advantage of the kit according to the invention now lies in that it can be attached directly to the formwork 6 of a roof, with one for noise insulation and sealing of the roof

Intermediate layer 6a, e.g. a cardboard layer or foil, 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.

From FIGS. 2 and 3 it can be seen that the edge regions 11 of the continuing Support plates 8 are bent up. At one end 12 there is no arching due to the punching. This area is used for vernage ment of the support plate 8 with the formwork 6. Subsequently, a further support plate 8 is placed with its edge area on the area 12 hung up. The overlap creates a corresponding seal the nailing point; at the same time arises from the semicircular or a three-quarter circular arch a more or less continuous receptacle for the straight web of the line 2. In the case of the end support plate 7, as shown in FIG. 4, the edge area at 13 can be recessed somewhat longer, so that there is sufficient space for taking up the point of curvature 4 of the line 2 remains. It should be made clear, however, that the curvature 4 extends over the gap the end support plate 7 each extends to the adjacent end support plate.

Approximately in the middle between each support plate 8 there is now a lath arranged, which can be nailed onto the formwork 6 through the intermediate layer 6a. Then cover plates 9 are now on the straight Bars of the line 2 pushed on and nailed to the lath 14, an overlapping arrangement of the cover plates 9 again being selected can be so that the nail points are covered. Finally, the end cover plates which cover the area of curvature 4 of the line 2 10 postponed. The end support plates 7 and the end cover plates 10 are correspondingly hook-shaped at their edges

bent over so that there is a neat finish on the edge of the eaves 5 results.

If the webs of the lines 2 are circular in cross-section, then If the edge areas of the support plates and cover plates are generally also bent in a semicircle or three-quarter circle, see above that there is a full contact of the cover plates and the support plates on the straight webs of the line 2. This results in a very good heat transfer from the support plates 8 and the cover plates on 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 20 cm, this means that a maximum heat flow path of 10 cm is not exceeded over the entire roof. That Accordingly, the roof only cools down by a few degrees Celsius compared to the ambient air temperature, even with intensive heat extraction. So could, for example, with heat pump operation at an outside temperature of plus 5 C and full heating of a single-storey bungalow building a maximum cooling of the roof compared to the outside temperature of 2 C can be determined. When exposed to sunlight in the Summer months arise with a bungalow construction of around 200 square meters

Roof area and a swimming pool with about 30 m water content shortening in the heating-up time from 1:10 to 1:30, even without using a heat pump operation compared to the heating-up of the Swimming pool due to the solar radiation falling on the surface of the water. So while a swimming pool of this size in the summer months in continuous sunshine it takes an average of three days to heat the water from plus 17 C to plus 22 C. This heating interval extends to about three to five hours when the swimming pool water is pumped through line 1 and lines 2 will. Additional expenses are not required, since the swimming pool water is cleaned by a circulation system anyway.

809885/0521

pump is circulated. Because the entire roof is cooled during this process excessive heating of the rooms directly under the roof is also avoided. When performing an experiment achieved heat recovery with solar radiation and outside temperature 600 kcal / m / h. With an outside temperature of + 5 C.

2
A heat pump can achieve 12,000 kcal / h per 100 m of climatic area.

With reference to Fig. 6 it should be mentioned that the connection of the straight webs of the lines 2 to the corresponding channel of the strand 1 by means of a hose piece 3, which is carried out by hose ties 15 is attached to the corresponding pipe socket. By appropriate choice of the length of the hose piece 3, a corresponding Adjustment and compensation of differences in length can be made.

Referring to Fig. 7 it can be seen that the conduits 2 consist of pipes may exist or are formed at least at the connection points from tubes which form a screw thread on their outside Carry wire helix 16 and that the connection of the tubes with one another and / or with the collector 1 via engaging in the screw thread Connecting links 17 takes place. The connecting links 17 can have sleeves with internal threads - if necessary with two internal threads running in opposite directions - be. The connection is then made by screwing in the pipe ends or twisting the sleeves. However, it can also be plastic or elastic members are used into which the wire helix 16 forming the screw thread is pressed.

It should also be mentioned that the lines 2 also have a square, may have a rectangular or polygonal cross-section, in which case the bent-up edges of the support plates and the cover plates will then Cross-section to be adjusted.

8374 809885/0521

It can be seen from Fig. 1 that in the kit according to the invention a minimal space requirement in the roof to accommodate the lines 2 is required. Compared to known climatic roofs, which require voluminous constructions, this falls with it the roof made according to the load does not increase the weight at all, for example 1.5 cm; on the contrary, through the alternating elevation of the roof in the area of the cover plates 9 and the recess of the roof in the area of the support plates 8 results a loosening of the roof structure, which is architecturally very appealing. From the outside, the roof is no different from a normal one Looking at the tin roof. It is also not possible to tell that the roof made with the kit is a climatic roof.

The corresponding sheets can be made of copper or aluminum alloys exist. They can be kept in a corresponding dark shade to increase their heat absorption capacity. The sheets can also be replaced by extruded parts or plastic parts. In this case, the lines 2 can form channels in the extrusions be provided.

The support plates 8 and the cover plates 9 can be of identical design which simplifies the kit accordingly.
