    Description TECHNICAL FIELD The invention relates to an insulating glass having at least two glass panes with a ventilation device to allow an exchange of air from a first side of the insulating glass to a second side of the insulating glass, wherein the ventilation device has at least one fan to the To promote air.
    Background Art A window typically includes a window frame and a sash. The window frame is anchored in a wall and serves to receive the window sash. The window sash is either firmly connected to the window frame, that is, for example, it is screwed once with the window frame, or the sash is hinged by hinges on the window frame. In this case, the window can be opened or closed by opening and closing the window sash. The window glass holds the window glass. However, there are also known designs in which the window glass without window sash can be mounted directly in the window frame. This design is also referred to as fixed glazing.
    In the prior art windows are known which comprise a ventilation device. This is either integrated in the window frame or arranged between the window sash and window frame. Such a ventilation device allows air between an interior of a building and the environment of the building to replace without the window sash of the window must be opened. This allows reliable burglary protection. In addition, such windows with ventilation devices allow decentralized ventilation of the building. For example, fresh and cool air can be led into a building from the outside, or warm air can be conveyed from the interior of the building to the outside.
    Frequently, such aeration devices on a heat exchanger to allow the exchange of heat energy between two air streams. For example, outside air can be heated or cooled before it is discharged into the interior of the building.
    Furthermore, the ventilation devices usually include a filter device with which the exchanged air can be filtered. Such an air filter can serve to filter dust-like particles, for example, to filter harmful gases from the air sucked.
    Such windows with ventilation devices sold, for example, the company Schüco under the name «Vento Therm». The ventilation device is horizontal, above or below the casement or vertically next to the casement in a special window frame can be installed. The ventilation device comprises a fan with an air filter and a heat exchanger to heat cold supply air from the outside with exhaust air from the inside, so that the heat loss can be reduced.
    Also AT 514 216 A1 (G. Cebrat) describes a window with a ventilation device. In this case, a panel is arranged in the window frame, which includes a fan, a heat exchanger and on the outside of a photovoltaic panel. The energy converted into electricity via the photovoltaic panel is used to operate the ventilation device.
    Another embodiment of a ventilation device in a window discloses US 2008/0 092 456 A1 (Pleo-tint LLC). This describes a window construction with a triple glazing. Between an outer window pane and an inner window pane is a middle pane of glass. The gaps formed by the windows include air or a gas. By means of convective air flow against the middle glass pane, heat can be removed from the gap and from the inner window pane. By automatically operable ventilation slots in an upper and lower portion of the window frame, the air flow between the middle window pane and the inner window pane can be regulated. Heated air can be directed in or out, as needed for heating or cooling.
    From the prior art known windows with ventilation devices have the disadvantage that they require a special window frame. This means that conventional window frames can not be used for windows without a ventilation device. The production of special window frames increases the manufacturing and assembly costs for the window. In addition, known windows with ventilation devices are undesirably visually striking.
    DESCRIPTION OF THE INVENTION The object of the invention is to provide an insulating glass belonging to the technical field mentioned at the outset with a ventilation device which is easy to install and visually inconspicuous.
    The solution of the problem is defined by the features of claim 1. According to the invention, the ventilation device of the insulating glass is arranged on a first edge of the insulating glass.
    As a result, the insulating glass can be mounted together with the ventilation device without special technical effort and in a simple manner in a conventional window frame or in a conventional receptacle of a facade system. Since no special window frame has to be manufactured, but a standard window frame can be used, time and costs can be saved. In addition, the ventilation device is visually unobtrusive.
    Insulated glass is understood to mean a window glass arrangement which comprises at least two glass panes between which there is an airtight cavity. In this cavity is a gas, preferably sulfur hexafluoride, argon or krypton. The insulating glass is either mountable in a window sash of a window or mounted directly into the window frame for windows without sash. The window frames are usually made of window profiles, which consist of metal, in particular aluminum, plastic, wood or a combination of these materials.
    In the present text, the information above, below and laterally refer to a reference system of an imaginary (fictitious) window, which is installed in an imaginary building, it being assumed that the inventive insulating glass is in a window frame of the imaginary window built-in.
    For the operation of the ventilation device, the inventive insulating glass must not be moved. However, there is the possibility that the insulating glass is installed in a window frame, which is pivotally mounted relative to a frame and regardless of the function of the ventilation device is pivotable relative to the frame to open the window or close.
    In the first edge, on which the ventilation device is arranged, it may preferably be the upper, the lower or a lateral edge of the insulating glass. This means that the ventilation device can be arranged in an upper, in a lower or in a lateral region of the insulating glass. Preferably, however, the first edge is the upper edge of the insulating glass.
    The glass sheets can be made of different transparent or non-transparent glass. Preferably, the first and second glass sheets are made of transparent float glass.
    Preferably, the ventilation device is shaped and dimensioned such that it extends along the entire first edge, wherein the ventilation device at least partially rests on the at least two glass panes and on an edge composite, which is arranged between the at least two glass panes. Preferably, the ventilation device is attached to the at least two glass panes and the edge bond.
    This means that the ventilation device at least partially rests on the edge surfaces of the at least two glass panes, which are directed in the direction of the first edge of the insulating glass, and at least one edge bond between these two glass panes, this therefore touched at least partially. A person skilled in the art is known in connection with insulating glass, the term of the edge bond: An edge bond usually includes a spacer which is disposed between the at least two glass sheets and adhesive and sealing material. As a rule, the edge seal will have an adhesive or sealing material towards the first edge, for example a polysulfide or polyurethane. This means that the ventilation device will usually rest on the edge surfaces of the at least two glass panes and the adhesive or sealing material of the edge seal.
    Preferably, the ventilation device along the entire first edge on the at least two glass panes and the at least one edge bond.
    Preferably, the ventilation device is glued by means of an adhesive with the at least two glass panes and the edge bond. This allows the simplest possible installation of the ventilation device. Particularly preferably, the adhesive is chosen such that it is compatible with the adhesive or sealing material of the edge bond. In particular, the adhesive should be chosen such that material exchange between adhesive and adhesive or sealing material of the edge bond takes place.
    The ventilation device preferably has a housing, wherein a first surface of the housing, which is in contact with the ventilation device on the at least two glass panes and the at least one edge seal to a first side, which is outside the intended use of the insulating glass, is directed is configured such that this first surface with the first glass is flat.
    Preferably, the sides of the ventilation device, which do not rest on the at least two glass panes and on the at least one edge seal, on a flange which is replaceable in a profile of a window frame.
    Due to the presence of such a flange, the insulating glass is particularly easy to use in a window frame. In particular, the flange is shaped and dimensioned to have the same shape and dimensions as the remaining edges of the insulating glass. Preferably, the insulating glass and thus also the flange of the ventilation device is shaped and dimensioned such that the insulating glass together with the ventilation device in a conventional window frame made according to DIN EN 14351-1; 2016-12 is applicable.
    In a preferred alternative, the ventilation device is arranged on the first edge of the insulating glass behind a first glass pane of the at least two glass panes of the insulating glass. In the intended installed state of the inventive insulating glass is at the first glass to an outer, a
    Interior of the building facing away from the glass. Accordingly, the first glass pane is located on an outside of the window. On the other hand, the second pane of glass is an inner pane of glass facing an interior of the building, which is located on the inside of the window. It is irrelevant whether the insulating glass comprises only the first and the second glass pane or whether further glass panes are arranged between the first and the second glass panes.
    Accordingly, preferably the first side of the insulating glass on the outside of the window and the second side of the insulating glass are on the inside of the window.
    The first glass pane includes at least one opening for the passage of air to allow an exchange of air from the first side of the insulating glass to the second side of the insulating glass. It is irrelevant which shape has the opening. The opening may, for example, have a round or rectangular shape, in particular the shape of slots. Preferably, only the first glass pane comprises at least one opening, so that optimum thermal and acoustic insulation can be achieved by the insulating glass.
    Preferably, the ventilation device has at least a first air passage, which allows the exchange of air from the first side to the second side of the insulating glass, as well as at least one second air passage, which allows the exchange of air from the second side to the first side.
    By the first and the second air passage of the exchange of air is made possible in a simple and efficient manner. The air duct is preferably tubular. In variants thereof, the air channel in cross section, for example, also rectangular, in particular as a narrow slot, be formed. Furthermore, the first and second air ducts may be rectilinear or curved along their longitudinal axis. Preferably, the first and the second air duct both rectilinear and curved sections.
    Preferably, the ventilation device comprises a plurality of first air channels and a plurality of second air channels. As a result, at the same time more air can be conveyed from the first side to the second side of the insulating glass by means of the first air ducts and at the same time more air can be conveyed from the second side to the first side of the insulating glass by means of the second air ducts. This allows a quick exchange of air from the first side to the second side and vice versa.
    If the ventilation device has a plurality of first air channels and a plurality of second air channels, preferably a respective first air channel is adjacent to a second air channel. This allows an exchange of thermal energy between the air channels. In a variant of this, the plurality of first air ducts can also be arranged side by side in each case in a group, and the several second air ducts can be arranged next to one another.
    Alternatively, there is also the possibility that the ventilation device does not comprise air ducts. In such an alternative embodiment, the air may be directly conveyed through openings in the first glass sheet to allow for exchange of air from the first side to the second side of the insulating glass and vice versa.
    Preferably, the ventilation device has a heat exchanger, which allows the exchange of heat energy between air in the at least one first air duct and air in at least one second air duct. As a result, the temperature in the interior space on the second side of the insulating glass can be efficiently used to a selected temperature level or kept efficiently at this temperature level. This reduces the effort for heating or cooling the interior. Thus, for example, by the heat exchanger air, which is conveyed from the outside from the first side to the second side of the insulating glass in the first air duct, are heated by the air from the inside, from the second side to the outside of the first side of the insulating glass in the second air duct is encouraged. This feature is also referred to as heat recovery. Conversely, depending on the outside temperature on the first side of the insulating glass and the inside temperature on the second side of the insulating glass, also air in the second air duct cool the air conveyed inwards in the first air duct.
    Under heat exchanger, any device is understood that can transfer thermal energy from a first air flow to a second air flow. Heat exchangers are also referred to as heat exchangers. Heat exchangers with different geometric guides of the air streams are known to the person skilled in the art. Thus, the heat exchanger may be formed, for example, as a countercurrent heat exchanger, DC heat exchanger, cross-flow heat exchanger, eddy current heat exchanger or cross-countercurrent heat exchanger. Preferably, the ventilation device comprises a countercurrent heat exchanger.
    Alternatively, there is also the possibility that the ventilation device has no heat exchanger.
    Preferably, the heat exchanger is an enthalpy heat exchanger. This allows the moisture in the interior to be kept at a certain level. Thus, for example, with the enthalpy heat exchanger, the moisture of the air in the second air duct can be transmitted to the air entering the building in the first air duct. As a result, a large part of the humidity can be recovered from the exhaust air. This is particularly advantageous in cold seasons, when the indoor air is rather too dry.
    In an alternative embodiment, the heat exchanger may be formed as a conventional pipe or plate heat exchanger without possibility for moisture exchange.
    Preferably, the at least one first air duct and the at least one second air duct each have a fan, preferably via a centrifugal fan to promote air through the at least one first air duct and through the at least one second air duct. This allows an efficient exchange of air from the first side to the second side of the insulating glass and vice versa. Preferably, with each fan, the airflow generated is at least 7 m3 / h.
    In an alternative variant, the fan may also be designed as an axial fan, diagonal fan, centrifugal fan or tangential fan.
    There is also the possibility that the ventilation ducts have no fan. The exchange of air can then be done for example by natural convection.
    Advantageously, the at least one first air duct and the at least one second air duct are each connected to an opening, wherein the at least one first air duct and the at least one second air duct in a first portion adjacent to the opening, relative to the first glass pane have an angle of at least 45 °. Preferably, in the intended installation of the insulating glass, the first and the second air duct from the opening upwards. As a result, no water can accumulate in the air ducts. In particular, this can prevent the penetration of rainwater. Thus, damage to the ventilation device can be avoided. This arrangement of the air ducts is also referred to as driving rain protection.
    Depending on the intended position of the ventilation device on the upper, lower or side edge of the window, the first and the second air duct are designed such that they preferably always have a first portion adjacent to the opening, which is relative to the first Glass pane at an angle of at least 45 ° and points upwards.
    In an alternative embodiment, the first portion of the first and second air duct or the entire first and the entire second air duct may also be arranged at right angles to the first glass pane.
    In one embodiment of the insulating glass, in which the ventilation device is arranged behind the first glass pane, the openings are in the first glass pane.
    In one embodiment of the insulating glass, in which the ventilation device rests on the at least two glass panes and the at least one edge seal, the openings are arranged in the housing of the ventilation device.
    Preferably, the at least one first air duct and the at least one second air duct comprises an electromechanical closing flap in order to close or open the at least one first air duct and the at least one second air duct, wherein the air dampers are preferably thermally insulated. By means of the louvers, the air ducts can be closed completely and preferably independently of each other. This makes it possible to completely interrupt the exchange of the air from the first side to the second side of the insulating glass and from the second side to the first side of the insulating glass or to interrupt the exchange of the air in one direction only. Thus, for example, the exchange of air and thus the temperature on the second side of the insulating glass in the interior of the building can be controlled.
    Preferably, the flaps are connected to a controller, so that depending on the temperature, the air ducts can be opened or closed automatically. The closure flaps are preferably thermally insulated so that the insulating function of the insulating glass pane is maintained even when the flaps are closed. The thermal insulation can be done by a suitable material selection or by equipping the flaps with a thermally insulating material.
    Alternatively, there is also the possibility that the air ducts do not comprise closing flaps.
    Preferably, at least one solar cell is arranged between the first glass pane and the ventilation device in order to supply the ventilation device with power. As a result, the ventilation device can be operated independently of an external power source or the power network of the building. In addition, the solar cell enables cost-effective and environmentally friendly power generation.
    Preferably, the solar cell is thermally insulated between the first glass sheet and the ventilation device arranged so that the function of the insulating glass is maintained and possible no thermal energy between the first side and the second side of the insulating glass is replaced.
    The ventilation device preferably comprises an energy store, in particular a battery, in order to be able to store the current generated by the solar cell. With the energy storage, the power supply is guaranteed even in a weather, in which the solar cell provides no electricity.
    In an alternative embodiment, the ventilation device can be fed, for example, with electricity from a power grid of the building or other power source.
    Alternatively, in the embodiment in which the ventilation device rests on the at least two glass panes and the at least one edge seal, a solar cell can be used. In this case, the solar cell is arranged on the first surface of the housing of the ventilation device.
    Preferably, the ventilation device comprises an electronic control for automatically controlling the ventilation device. Advantageously, the ventilation device can automatically control the climate on the second side of the insulating glass based on sensor data. If the ventilation device includes solar cells and a battery, the controller preferably controls the flow of current. Thus, the controller can ensure that the electrical consumers of the ventilation device are supplied either with power from the battery or with power from the solar cells.
    Alternatively, there is also the possibility that the ventilation device comprises no control. The ventilation device can be manually operated in this case.
    Preferably, the ventilation device has a receiver with which wireless control commands, in particular for the electronic control, can be received. This allows a user, for example, by means of a remote control, the air exchange from one side of the insulating glass on the other side targeted influence. The receiver may be an infrared or radio wave receiver. Particularly suitable as radio wave receivers are receivers which support common transmission protocols, for example according to the standard IEEE 802.15.1 (Bluetooth) or IEEE 802.11 (Wireless LAN).
    Preferably, the ventilation device comprises a thermal insulation. Thereby, the thermal insulation function of the insulating glass is maintained, despite the presence of the ventilation device. This reduces the expense of cooling or heating on the second side of the insulating glass in the interior of the building. The thermal insulation is preferably formed in the form of a thermal insulation panel of thermally insulating materials, such as wood, glass fiber reinforced plastics with polyester or polyurethane or dimensionally stable, foamed plastics.
    The thermal insulation is preferably located between the first glass pane and a housing of the ventilation device. At this point, the thermal insulation can be used particularly efficiently. The thermal insulation may additionally be arranged above the housing of the ventilation device, laterally of the housing or under the housing. In a further embodiment, the ventilation device may comprise a thermal insulation which surrounds the ventilation device from all sides, so that an optimal thermal insulation between the first side and the second side of the insulating glass is made possible. If the ventilation device has at least one solar cell, it is arranged between the first glass pane and the thermal insulation.
    Advantageously, the ventilation device is shaped and dimensioned such that it forms a flange together with the first glass pane at the first edge, which can be inserted into a profile of a window frame. The flange allows a simple and rapid installation of the insulating glass with the ventilation device in a window frame or in a facade system. Preferably, the insulating glass is made with the flange in a conventional window frame according to DIN EN 14351-1; Can be used 2016-12.
    Preferably, the insulating glass has three glass panes, wherein the first glass pane in the region of the first edge projects beyond the two further glass panes, so that the ventilation device is arranged in this area behind the first glass pane, wherein the ventilation device with the first glass pane and with a Edge bond between the first glass sheet and a second glass sheet of the insulating glass and an edge bond between the second glass sheet and a third glass sheet of the insulating glass is glued.
    The second and the third glass pane are thus dimensioned such that in the insulating glass in the region of the first edge behind the first glass pane, a recess is formed, in which the ventilation device, solar cells as well as a thermal insulation are arranged. Such an arrangement allows a particularly space-saving design. As a result, the insulating glass is easy to install and the ventilation device is visually inconspicuous placed behind the first glass pane.
    An insulating glass with three glass panes allows optimum isolation, since in each case between the first and the second glass sheet and between the second and the third glass slide a gas-filled gap is formed, which improves the insulation effect.
    In an alternative embodiment, the ventilation means is disposed between the first glass sheet and a second glass sheet, the first and second glass sheets being the outermost glass sheets on the first side and the second side of the insulating glass. This allows a very compact construction of the insulating glass. In addition, the ventilation device is optically very inconspicuously placed in the insulating glass. In order to allow air flow, the second glass pane has corresponding openings through which air can flow.
    From the following detailed description and the totality of the claims, there are further advantageous embodiments and feature combinations of the invention.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a perspective view of an insulating glass 1 according to the invention with a ventilation device 2.
    In the embodiment shown, the insulating glass 1 is formed as a triple glass with three individual glass sheets 8, 9, 10. At a first edge 23 of the insulating glass 1, a ventilation device 2 is arranged. The ventilation device 2 is arranged behind a first glass pane 8. By means of the ventilation device 2 can be exchanged air from a first side 27 of the insulating glass to a second side 28 and vice versa. In order for air to enter through the first glass pane 8 into or out of the ventilation device 2, the first glass pane 8 has a first opening 7.1 and a second opening 7.2.
    The ventilation device comprises a ventilation module 3, which is enclosed by a housing 17, a heat insulation 4, which is designed in the form of a thermal insulation panel, and a solar cell 5. In the embodiment shown, the heat insulation 4 between the solar cell 5 and the Housing 17 of the ventilation module 3 is arranged. The solar cell 5 directly adjoins the first glass pane 8. As a result, the solar cell 5 can generate electricity by light which shines through the first glass pane 8 in order to operate the ventilation device 2.
    The insulating glass 1 can be installed in a window frame or directly in a facade element. The window frame is embedded in a wall, in particular in a masonry, of a building. When installed, the first glass pane 8 of the insulating glass 1 is located on the first side of the insulating glass 1, which is located on an outside of the building. A second glass pane 10 of the insulating glass 1 is located on the second side of the insulating glass 1, which is located in the installed insulating glass 1 on the inside of the building. When installed, the first edge 23 - and thus the ventilation device 2 - is at the top of the window. Of course, however, the insulating glass 1 can also be designed such that the first edge 23 and with it the ventilation device 2 is located below or laterally on the window. Preferably, however, always the first glass pane 8 is arranged on the outside to protect the ventilation device 2 from the weather.
    Fig. 2 shows the inventive insulating glass 1 in a schematic representation of the side in the sectional view, wherein the first side 27 of the insulating glass 1 on the left and the second side 28 of the insulating glass 1 is right. In Fig. 2, the contents of the ventilation device 2 can be seen.
    The insulating glass 1 comprises a first glass pane 8, a second glass pane 10 and a third glass pane 9 lying between them. These glass panes 8, 9, 10 are made of transparent float glass. In the described embodiment, the entire width of the insulating glass 1, ie the distance between an outer surface of the first glass pane 8 and an outer surface of the second glass pane is 1042 mm. Between the first glass pane 8 and the third glass pane 9 as well as between the third glass pane 9 and the second glass pane 10 there is in each case a peripheral edge compound 13.1, 13.2. These edge joints each comprise a seal and a spacer 11.1, 11.2 with a dehumidifying insert. By the spacers 11.1, 11.2, the glass sheets 8, 9, 10 held at a predetermined distance from each other. The glass sheets 8, 9, 10 are each bonded by the edge seal 13.1, 13.2 randumlaufend each other. The spacers 11.1, 11.2 are made of a thermally insulating plastic such as cured polysulfide.
    By the distance between the first glass pane 8 and the third glass pane 9 is a first space between the panes 20.1 and the distance between the third glass pane 9 and the second glass pane 10, a second space between the panes 20.2 is formed. Both disc spaces 20.1,20.2 are closed by the edge seal 13.1, 13.2 against the outside gas-tight. In the first space between the panes 20.1 and 20.2 in the second space is a mixture of air and argon, which counteracts a gas convection in the space between the panes 20.1, 20.2.
    The solar cell 5, the thermal insulation 4 and the ventilation module 3 are arranged in a region of the first edge 23 of the insulating glass 1 behind the first glass pane 8. The first glass pane 8 projects beyond the third glass pane 9 and the second glass pane 10 in the area of the first edge 23. In other words, the third glass pane 9 and the second glass pane 10 form a recess in the region of the upper edge 23 of the insulating glass 1. In this are behind the first glass 8 8 first, the solar cell 5 and seen in the horizontal direction behind this the thermal insulation 4 is arranged. Behind the thermal insulation 4, the housing 17 of the ventilation module 3 is mounted. The thermal insulation 4, the solar cell 5 and the housing 17 extend horizontally over the entire length of the insulating glass 1, as shown in FIG. 1.
    With a glue joint 12, the ventilation module 3 is glued to the first glass pane 8 and to the first edge seal 13.1 and to the second edge seal 13.2. This arrangement with the thermal insulation 4 and the insulating edge joints 13.1, 13.2 ensures that no cold bridges are present. By coating the glass panes 8, 9, 10, for example by sputtering, the surfaces of the glass panes 8, 9, 10 can be designed so that they either reflect heat radiation (low-E coating) or absorb heat radiation (sun protection coating).
    As can be seen in FIG. 2, the housing 17 of the ventilation module 3 overlaps the third glass pane 9 and the second glass pane 10 in the direction of the first edge 23. The housing 17 is also not flush with that of the first edge 23 arranged first glass 8, but has the edge of the first glass sheet 8 at a distance of about 25 mm. This creates a shoulder which forms a flange 24 which has the same width as the width of the three glass panes 8, 9, 10 including the width of the edge joints 13.1, 13.2. With this flange 24, the insulating glass 1 can be mounted in a conventional window frame or in facade elements. Thanks to this flange 24, the insulating glass 1 according to the invention can be mounted like a standard insulating glass without ventilation device in a window frame or in a receptacle of a facade element. A conventional window frame can be made of plastic, in particular PVC.
    The thermal insulation 4 consists of a thermally insulating material such as wood, glass fiber reinforced plastics with polyester or polyurethane or of a dimensionally stable, foamed polystyrene. At the same time, the thermal insulation 4 serves as a sound insulation, so that with the inventive insulating glass 1 an equally high noise insulation can be achieved, as with conventional insulating glass.
    The ventilation device 2 further comprises a first air duct 6.1 for exchanging air from the first side 27 to the second side 28 of the insulating glass 1 and a second air duct 6.2 for exchanging air from the second side 28 to the first side 27 of the insulating glass first For this purpose, the tubular air channels 6.1, 6.2 are each connected to the opening 7.1, 7.2 in the first glass 8. From the first glass pane 8, the air ducts 6.1, 6.2 each lead through the solar cell 5 and through the thermal insulation 4 into the housing 17 of the ventilation module 3. This course can be seen in FIG. 2 for the first air duct 6.1. The second air channel 6.2 is not shown in Fig. 2, since this is behind the first air duct 6.1 in the viewing direction. However, it has the same course as the first air duct 6.1. The arrangement of the closure flap 15.1, 15.2 and the centrifugal fan 16.1, 16.2 described below is the same for the first and second air duct 6.1, 6.2.
    In the embodiment illustrated in FIGS. 1 and 2, a first air duct 6.1 is arranged directly next to a second air duct 6.2. In alternative embodiments, the insulating glass 1 can also have a plurality of first air channels 6.1 and second air channels 6.2, which are preferably arranged in pairs.
    The first air duct 6.1 and the second air duct 6.2 each comprise a first section 21.1, 21.2 and a second section 22.1, 22.2. The first section 21.1, 21.2 is configured obliquely and assumes an angle of at least 45 ° relative to the first glass pane 8. In the embodiment shown, the first section 21.1, 21.2 extends from the first glass pane 8 through the solar cell 5 and through the heat insulation 4 upwards. By this first section 21.1,21.2 can accumulate no water in the air channels 6.1,6.2. This avoids that water in the air ducts 6.1,6.2 can cause damage. The second sections 22.1, 22.2 extend horizontally within the housing 17 of the ventilation module 3. At the rear end of the air ducts 6.1, 6.2 on the inside of the insulating glass 1 is ever an electromechanical shutter 15.1, 15.2 arranged.
