Description

"Energy element"

Technical field of the invention

The invention relates to an essentially disk-shaped energy element arranged on a component. Furthermore, the invention relates to an elastic profile and the use of such, as well as the use of a sheet metal standing seam roofing membrane.

State of the art

Special attention must be paid to thermal expansion when fastening and connecting energy elements. In the case of small energy elements, this does not pose any special requirements, but the solar energy user is concerned with systems that are as large as possible. Large areas are in particular on industrial roofs, which are very often covered with sheet metal.

For the fastening of such solar energy panels on roof surfaces or in facades of buildings, one has to intervene in the building envelope. However, this is particularly undesirable in sheet metal roof areas, since it breaks through the necessarily rainproof sheet covering. When the panel is removed, damage remains and jeopardizes the tightness of the covering or requires an at least partial new covering of the roof. Since the roof surface must be resealed when disused solar systems are removed, many solar systems remain on the roofs even when they are no longer functional.

From WO-A-9508194 a solar roof tile or roof tile and a solar wall plate is known. The roof tile, roof tile or wall plate is made of clay,

Ceramic, concrete, fiber cement or plastic and serves as a support for a solar panel with photovoltaic solar cells. Elastic projections are formed on the solar panel on two opposite sides over a fraction of the length of these sides. The roof tile, roof tile or wall plate has a recess, in the side wall of which recesses are made of clay, ceramic, concrete, fiber cement or plastic. The projections snap into these recesses in a form-fitting manner are kept in it. Thanks to the inherent elasticity of the projections, this design of roof tiles and solar panels ensures that, despite manufacturing tolerances for roof tiles or roof tiles, the solar panels always find a secure and precise hold without damaging the solar cell during installation.

A disadvantage of this solar roof tile is that the solar cells used can only be small and must be adapted to the length and width of the roof tile. It is also only suitable for photovoltaic elements and not for heat generation. To fix these elements, recesses have to be worked into the roof tiles.

Object of the invention

It is an object of the invention to expediently arrange large-area, disk-shaped heat exchangers or photovoltaic elements on a component or building. At least one dimension of the area of these energy elements should be able to be selected independently of the component. When assembling the energy element, the component should not have to be processed or even broken through. When the energy element is dismantled, both the energy element and the component should remain intact.

Description of the invention According to the invention, this is done in the case of an essentially disk-shaped energy element (11) which is fastened to a component and has certain external dimensions, with an elastic profile (13) for fastening the energy element to the component (47), which profile (13) is attached to at least two opposite ones Edges (27) of the energy element (11) is arranged, achieved in that the component is a trough-shaped profiled sheet. Disc-shaped elements of various functions and origins can be used as the energy element. Explicit reference is made here to the PCT application PCT / CH 00/00434, which has not been previously published. This describes a heat exchanger or, better, a surface flow heat exchanger in which a sheet-shaped flow-through space for a heat exchange medium is formed from sheet metal, in particular copper sheet, by two sheet metal walls by means of regularly spaced punctiform points

Die connections are interconnected. Press connection says that the material of the two sheet metal walls has been deformed with one another or into one another in such a way that there is a kind of permanent snap connection between the sheet metal walls. The material of the one sheet metal wall engages behind the material of the other sheet metal wall. If these connection points are arranged at intervals of at most 4 cm, preferably about 2.5 cm from one another, two 0.55 mm thick copper sheet walls can be connected so stably that an overpressure of up to 5 bar can be built up without them the connections are torn apart or the sheets deform in an uncontrolled manner.

Reference is also made here to the unpublished Swiss patent application no. 2000 2155/00, in which a heat exchanger is described. The

The heat exchanger has an interior space between two parallel sheet metal walls. The sheet metal walls are connected to one another at a large number of points. A stiffening edge stiffening the wall is formed around the connection points. In addition to the press mold connections mentioned, this also permits soldered and adhesive connections.

In addition to water-air heat exchangers, energy element is also understood to mean water-water heat exchanger, air-air heat exchanger, solar or zenith radiation collectors, photovoltaic elements, etc. Another liquid heat transfer medium is included under water, and another gaseous heat transfer medium is included under air. A particularly advantageous energy element consists of a photovoltaic element cooled by means of a heat exchanger element. The heat exchanger element and the photovoltaic element together form a unit in that the photovoltaic element is applied to the heat exchanger element in a heat-conducting manner. It is also possible to combine two independent elements with one another in such a way that the photovoltaic element can be cooled with the heat exchanger element.

Disc-shaped means that two opposite views of the element have a large area, the other views are practically linear in comparison with the two large area views. The element therefore forms a disc with two dimensions in a first order of magnitude, for example in a ratio of 1: 1 to 1:30 and the third dimension in a much smaller second order of magnitude, in relation to the other two dimensions approximately 1: 20 to 1: 1000 , In other words: the thickness of the disc is, for example, within a range from 0.2 to 1 or maybe up to 2 cm, while the other dimensions of the disc are, for example, between 10 cm and 10 m. These dimensions and ratios are illustrative and not restrictive. In the following, component is to be understood as a component of a house or for a building, but also part of another built structure, for example a frame or a box. The attachment of the energy elements on trough-shaped profile sheets allows the

Construction of large-scale solar systems with appropriately large energy elements. Since the profiled sheet metal sheets are trough-shaped and are made in any length, the length of the energy elements is not limited by the limited length of the component. Since the profiled sheet has a channel bottom and two channel walls that are approximately opposite each other to the channel bottom, the elastic profile only needs one back opposite the groove, with which it rests on the channel walls opposite one another. The energy element sticks to the channel walls thanks to the friction between the channel wall and the profile.

There is advantageously a tension within the energy element and profile, so that the energy element clamps between the walls. This voltage can be achieved by appropriate dimensioning of the external dimensions of the energy element. If the energy element, in particular a flat heat exchanger, is divided along a line parallel to the longitudinal direction of the profiled sheet web, the tension perpendicular to the edges of the profiled sheet web is achieved by spreading them apart with a spreading device between the two parts of the energy element.

The energy element necessarily has at least one connection for a line for energy transfer away from the energy element. However, it is also possible for the energy transfer to take place towards the energy element. In the case of photovoltaic elements, this connection consists of an electrical line. With heat exchangers like

Solar heat collectors or air-water heat exchangers are required for this. Connection with supply and discharge for the heat exchange medium is necessary. Air-air heat exchangers accordingly require a supply air pipe and an exhaust air pipe.

The elastic profile is advantageously matched to the cross-sectional shape of the channel wall of the channel in which the energy element is to be fastened in such a way that the elastic profile can be arranged between two constricting projections provided in the channel wall. The constrictions are through against each other directed projections formed on the walls, one of the constrictions is advantageously given by the channel bottom. Again, it is useful that a tension in the elastic profile is achieved between the constriction and the channel bottom, or between the two constrictions, thanks to which the profile clamps. The coordination between the profile height (dimension perpendicular to the plane of the disk-shaped energy element) of the elastic profile and the distance between the projections means that the energy element cannot be moved in the direction perpendicular to the disk plane. Wind and snow loads are therefore transferred to the profiled sheet web and do not lead to a shift of the energy element with respect to the profiled sheet web.

A profiled sheet which forms a channel and is suitable for accommodating energy elements is a profiled sheet roofing membrane. Profiled sheet metal facade cladding is also to be designed in a gutter shape. The length of the channel can correspond to the length of the element or exceed it as desired. This has the advantage that the length of the element can be selected independently of the length of the channel. Several, in particular standardized, energy elements can also be arranged in a row in a long channel.

The elastic profile is advantageously formed all around the energy element. The fact that the profile is arranged on the four sides of a right-angled, disc-shaped energy element achieves a certain termination of the element. This creates an insulating air cushion between the energy element and the channel floor. Thanks to this air cushion, the thermal insulation of the thermal insulation can also be used, for example, in a roof structure. In the case of energy elements arranged in profiled sheet metal roofs with beads formed in the channel floor, the strips filling the deep beads can be arranged between the elastic profile and the profiled sheet. If the elements are arranged on the ridge, a ridge cover can adjoin the element so that rainwater or meltwater does not flow under the energy element and does not cool the energy elements from the rear. However, since hardly any solar energy is obtained when it rains, there is no significant advantage in sealing the space between the energy element and the roof skin in a watertight manner. On the other hand, a wind seal, in particular at the lower end of an energy element, can be expedient. As a wind seal, a pivoting flap can be useful, which allows water to drain and through Wind pressure is closed. This prevents wind from driving under the disc-shaped element and tearing it out of its anchoring.

A groove is advantageously formed in the elastic profile, with which the edge of the energy element is engaged. Alternatively, a series of recesses can also be provided in the profile, into which extensions arranged on the energy element engage. However, a groove is easier to form in a profile than a series of recesses. The energy element is held in the groove or the recesses and can experience length changes under the influence of temperature differences. The changes in length are absorbed by the profile and / or by sliding between the profile and the energy element and / or between the profile and the channel wall.

Two grooves are advantageously formed side by side on the elastic profile. The edges of the energy element are arranged in a first inner groove, which is to be arranged in particular toward the channel bottom. A translucent pane or a photovoltaic element is arranged in a second, outer groove. The arrangement of a pane in front of the energy element creates a so-called heat trap provided the space between the pane and the energy element is closed.

Alternatively, two profiles can also be arranged next to one another, a groove being formed in each profile. The two grooves are to be used in the same way as if they were present in a single profile. The division of the grooves into two separate profiles has the advantage that profiles with different grooves can be provided for different solar elements, which can be combined as desired with a profile with a groove for a glass cover. A profile without a groove can also be formed in order to space a profile for a photovoltaic element from the channel bottom.

Special solar energy glasses, acrylic glass and the like are particularly suitable as the translucent pane. Photovoltaic elements are known in large numbers. These do not have to be translucent or particularly translucent to heat radiation. The advantage of arranging a heat exchanger element behind a photovoltaic element is that the heat generated is dissipated behind the photovoltaic element, so that the photovoltaic element has a lower temperature and therefore a higher efficiency. Heat recovery is just an additional benefit. The groove, or at least the outer groove, can advantageously be widened by elastically deforming a groove side wall in such a way that the disk intended for engagement in the groove (translucent disk or disk-shaped energy element) can be inserted into or removed from the groove transversely to the plane of the disk is. The arrangement of a pane (translucent pane or disk-shaped energy element) in front of the energy element creates a so-called heat trap provided the space between the pane and the energy element is closed.

Accordingly, an elastic profile, in particular an elastomer or rubber profile, is used as an intermediate profile between a disk-shaped energy element and a channel-shaped profiled sheet web in order to fasten the energy element.

In this case, a profile is advantageously used which has at least one groove for receiving the edge of the energy element and a back for an essentially form-fitting seat and / or a clamp seat on the channel wall.

Formations are formed on the channel walls to achieve a shape fit, which narrow the distance between the channel walls. The profile or part of the profile is stuck between these formations.

A particularly preferred embodiment of the channel with an energy element consists in the channel walls being formed by the standing seams of a profiled sheet-standing seam roofing membrane. These standing seams generally have an area that narrows the channel. This is formed by an overlap area of two adjacent profile sheets. If the energy element is embedded in the profile sheet with an elastic profile, it is not only visually unobtrusive in the roof area. It is also galvanically separated from the roof surface, which increases the freedom of choice of materials for profile sheet and energy element. If the profiled sheet is the upper shell of a warm roof, the thermal insulation of the roof structure also insulates the energy element.

If an essentially disk-shaped energy element of a certain length, width and thickness is to be fastened in a trough-shaped profiled sheet, the width or length of the energy element is accordingly matched to the distance between the walls, an elastic profile is arranged on the energy element and the energy element with the profile is between arranged in the channel walls so that a back of the profile facing the wall lies against one of the two walls. The gutter is accordingly with a gutter bottom and at a distance from the gutter bottom a narrowing of the distance between the channel walls. The elastic profile is then placed between the channel floor and the constriction.

According to the invention, a trough-shaped profiled sheet, e.g. a building cladding, used as a holding frame for a disk-shaped energy element with an elastic profile arranged on at least two sides of the disk-shaped energy element and held by the energy element at a distance that is matched to the dimension of the channel. A panel consisting of such a profiled sheet metal clothing element and an energy element therein can be set up independently of the usual determination of the clothing element or can be arranged anywhere on a building.

Fig. 5 is an energy panel with a bracket made of two sheet metal sheets. 6 shows a cross section through a rubber profile,

7 shows a section through a standing seam of a profiled sheet metal roof with a doubled rubber profile according to FIG. 4.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS FIG. 1 shows a cross section through a profiled sheet roof with a supporting structure 41, above it a vapor diffusion brake 43, a thermal insulation layer 45 and channel-shaped profiled sheets 47 lying directly on the insulating layer 45. The profiled sheets are in a known manner, placed on holders, which in turn are attached directly to the supporting structure 41, for example on Z-profiles resting on the supporting structure or with screws or rivets. Each profiled sheet 47 then has two lateral flanks 48, 49 on a groove bottom 53, which have mutually opposite walls 17, 18 and with which flanks 48, 49 the profiled sheets 47 are fastened to one another. The flanks 48, 49 have a head region 51 for the mutual fastening of the profiled sheets 47 to the wall 17, 18. In this head area 51, one flank 48 encompasses the other flank 49 of the adjacent profiled sheet. The two flanks 48, 49 of adjacent profiled sheets 47 thus form a common web 50. The head region 51 protrudes toward the energy element via the wall 17, 18. The disk-shaped energy element 11 is clamped between the webs 50 by means of elastic profiles 13 at its edges 27 parallel to the web 50. The cantilevering of the head region 51 has the effect that the elastic profiles 13 can become stuck between the head region 51 and the groove bottom 53 of the profile plate 47. Two grooves are formed in the elastic profiles 13. A glass 35 is arranged in the one on the outside and the energy element 11 in the other one on the inside. An insulating intermediate layer 55 is inserted between the energy element and the channel bottom 53. This is adapted to the shape of the channel bottom 53, which can have raised and lowered beads. In the case of the deep beads, it can also only rest on the raised beads, leaving a cavity open. This allows water between the intermediate layer 55 and the profiled sheet 47 to run off unhindered. The intermediate layer 55 keeps the disk-shaped energy element 11 at a constant distance from the groove bottom 53 of the profiled sheet 47 in one way or another. Even without the intermediate layer 55, the energy element 11 is thermally insulated, since thermal insulation 45 is arranged directly below the profiled sheet 47.

FIG. 2 shows the same roof as in FIG. 1. However, in order to have better exposure to the sun, the energy element 11 is mounted further outside. As a result, the shadows cast by the webs 50 are less. For this purpose, a rubber profile 13e is provided, which also has two grooves for the edges 27 of the heat collector 11 and disc 35 or, if appropriate, photovoltaic element 36. However, opposite the grooves, the back is provided with a concave recess into which the head region 51 of the webs 50 engages. FIG. 3 shows two possible configurations of elastic profiles 13 on the left and right of a web 50. Both profiles have two grooves 57, 59, one of which is outer for a translucent pane 35 and an inner one for a disk-shaped energy element 11. One profile 13a has one third groove in which a press-in cord 61 filling and spreading this groove is arranged. The other profile 13b has lips 63, 65. These lips 63, 65 are pressed against the web 50 by glass 35 and energy element 11. As a result, the grooves 57, 59 for glass 35 and energy element 11 are pressed together via compressive forces in the elastic profile 13b. As a result, both the elastic profile 13b between the head region of the web 50 and the channel bottom 53 and the disk-shaped elements 11, 35 hold in the grooves 57, 59.

The inner groove 59, in which the edge 27 of the energy element 11 is seated, is expediently matched to the shape of this edge 27. As shown in FIG. 5, the groove does not have to encompass this edge 27 in such a way that the energy element can only be inserted into the groove or pulled out of the groove by deforming the elastic profile.

FIG. 4 shows an elastic profile 13c, in which the groove 59 for the energy element is adapted to the cylindrical edge 27 of the energy element 11, is recessed approximately semi-cylindrical. This semi-cylindrical recess 59 is sufficient to hold the energy element 11 in the direction perpendicular to the plane of the channel bottom 53. A rectangular recess 57 is provided for a translucent pane or a photovoltaic element 36. This is delimited on the outside by a lip 71 that can be raised. This lip 71 holds the photovoltaic element 36 in the groove 57, but can be raised in order to remove the photovoltaic element 36 from the groove or to insert it into it. With the energy or heat exchanger element 11, the space between the photovoltaic element 36 and the channel bottom 53 is cooled, so that the photovoltaic element can operate with practically constant efficiency at low and high heat radiation.

Depending on the use, the elastic profile 13c can be placed in the profile plate with the groove for the energy element 11 toward the channel bottom or arranged outwards. As a result, an energy element 11 can be covered with a pane 35, or can be arranged uncovered using the same profile in the same plane as the translucent pane 35. This is particularly the case when using an energy element 11 through which a heat exchanger medium flows Photovoltaic foils 73 interesting. The performance of the photovoltaic film 73 can be increased by cooling. The heat medium preheated as a result can then be heated further, for example in adjacently arranged covered energy elements 11.

A combination of photovoltaic elements 36, 73 with heat exchanger elements 11 is also of interest regardless of their attachment. Photovoltaic elements are sensitive to temperature, i.e. their efficiency drops with increasing operating temperature. As a result, their efficiency is low, especially in high solar radiation, and the electricity yield is relatively low. The development in the Fotovoltaϊk tends to reduce the temperature sensitivity of the Fotovoltaelementek elements. On the other hand, expensive solar glass cover plates 35 are generally to be provided in the case of solar heat collectors 11. Without cover plates 35 there is no greenhouse effect and the collector temperatures to be reached are significantly lower than with a cover plate. As a cover plate 36 or as a coating 73 of a solar heat collector 11, it is therefore proposed to mount a photovoltaic plate 36 at a distance from the heat collector 11 or a photovoltaic film 73 directly on the heat collector 11. In this case, the highest possible thermal permeability of the photovoltaic element 36 should be aimed at if it has no or only a poor thermal connection to the heat collector. On the other hand, a thermally conductive connection between the photovoltaic element 73 and the heat exchanger element 11 allows the use of heat radiation collecting

Photovoltaic elements 73. Cooling the photovoltaic element 36, 73 with the heat exchanger element 11 as directly as possible brings about an increase in the efficiency of the photovoltaic element.

Figure 5 shows an energy panel. Energy panels can consist of sheet metal sheeting that is specially made for independently placeable panels. However, what is shown consists of a standard profiled sheet of a standing seam profiled sheet roofing membrane. This corresponds exactly to the roofing membrane according to FIG. 1 or 2. With a second profiled sheet, which corresponds to a roofing membrane with higher webs and with inverted head regions, a two-layer channel is created. This is closed at both ends with a lid. Thus, the identical elements as in the exemplary embodiments in FIGS. 1 to 4 can be used for a panel which can be moved anywhere. As a result, the production costs for such panels can be kept low. FIG. 6 shows a cross section through a variant 13d of a rubber profile according to FIGS. 3 and 4. In the profile 13d shown, the one groove 57 for a disk 35 or a flat photovoltaic element 36 is formed with an elastic lip 71. The other groove 59 is in the shape of a half-barrel with a rectangular groove 59 'in the apex of the half-barrel. The arched part of the groove 59 is designed in a serrated manner in order to allow greater freedom in the edge shapes of the energy elements to be fitted therein and to reduce the adhesion between the energy element and the profile in the longitudinal direction of the profile. The shape of the back 79 with the two quarter-round concave corner recesses 81 allows the arrangement of the profile with one or the other groove to the outside in a folding roof profile sheet with a round design of the profile head 51. The rectangular groove 59 'in the apex of the half-barrel-shaped groove 59 can accommodate a photovoltaic element, a glass pane or the like. It also enables an energy element to be removed from the groove 59 by allowing the barrel-shaped groove 59 to be expanded.

FIG. 7 shows the same roof structure as shown in FIG. 4. The two profiles to the left and right of the standing seam or web 50 are, however, designed to be continuous. A strip of material made from the same material of the profile connects the two profile parts, each corresponding to a single profile 13, across the web 50 to form a double profile 13e. The two mirror parts of the double profile 13e can have any shape. Thanks to the coherent design of the profile parts to the left and right of the web, the double profile 13e can be pushed over the web 50 and holds there even if no energy element is arranged on it. This considerably simplifies the assembly of the elastic profile with energy elements arranged next to one another. The double profile 13e can also be arranged between two adjacent energy elements if there is no web 50 in between.

A spreading device 83 is shown on the right side of FIG. This consists of a plate shaped as shown. In the example shown, it is placed on the trough bottom of the profiled sheet 443 and covers a support function for the glass 36. It is rotated by 90 degrees between the heat exchangers 11 and then rotated into the position shown. Since the thickness of the plate is smaller than that Distance at which the spreading device 83 holds the heat exchangers 11, the heat exchangers 11 are spread apart by the rotation of the spreading device 83.
