With the rise in energy prices, increasing attention has been paid to its economic use and austerity measures. The immediate utilization of solar energy has become topical when it has been noticed that more than 1 MWh / m of energy falls on the facades of buildings ... with the exception of 2 northern sides. In office buildings, sunshine has so far been understood as a purely negative factor. However, with suitable measures, its disadvantages can be eliminated and the radiation falling on the facades can be utilized, for example, in the air conditioning system of a building. In the office building, solar energy and operating time also occur simultaneously.

The present invention relates to a solar heat absorbing window structure consisting of a standard window pane and a heat absorbing thermal glass package spaced apart from the window pane and outside the room, at least a portion of the room exhaust air being adapted to pass through the space between the first window pane and the glass pane.

If the exhaust air in the room is led in a known manner between the inner glass and the outer glass, the inner glass is heated so much that there is no draft from the window and no heat radiators are needed. In known plants, the sun protection of the window is provided, for example, with roller blinds. The disadvantage of these is that they become dirty during use and are difficult to clean, and require unnecessarily frequent adjustments according to the sun in order to absorb heat as well as possible. On the other hand, it is also known to use an absorbent glass sheet as the outermost glass sheet of a window, whereby the heat absorbed by the sheet is transferred to the outside air.

The object of the present invention is to provide a window structure in which the heat of the sun can be transferred in an even simpler way to the exhaust air of the room, from which it can be recovered if desired, for example for heating supply air or domestic water. This object is achieved by a window structure according to the invention in such a way that the heat-absorbing glass sheet forms the outer delimiting wall of the space between the window glass sheet and the thermal glass package. As the exhaust air of the room flows in said intermediate space, it is heated by the action of absorbent glass, so that blinds which are always adjustable according to the height of the sun can be omitted. The window structure according to the invention naturally also acts as a protection against excessive heat in the room, as do known solutions.

The principle of the invention is shown in the accompanying drawing, in which Figure 1 shows a window structure according to the invention seen from the side, and Figure 2 illustrates the principle of heat-absorbing glass.

Figure 1 shows the window construction 1 consists of the usual window glass of a sheet 2, and this at a distance from the heat glass package 3, which, in turn, consists of the usual window glass sheet of ^ and heat absorbing glass sheet of 5 · All the plates are secured to the frame 6, Air exhaust air is passed arrow A as shown in the frame through the channels in the lower part to the intermediate space 7 of the plate 2 and the package 3 and through it to the upper part of the frame 8. As can be deduced from Figure 1, the ordinary window glass plate 2 is on the room side, while the thermal glass package 3 is limited to the outside air.

Figure 2 shows the principle of heat absorbing glass.

Absorbent glass is tinted glass that absorbs or absorbs a certain part (the part indicated by the absorption coefficient) of the sun's radiant energy.

The darkness of the glass is achieved, for example, by placing a metal, for example bronze or iron, in the glass mass, which binds radiation. Tinted glass can also be made by placing a dark film that also contains metal between two clear sheets of glass.

When the sun's radiation meets the absorbing glass, the portion indicated by the absorption coefficient remains here, as a result of which the temperature of the glass rises.

According to the invention, such an absorbent glass sheet 5 forms the inner sheet of the thermal glass package 3, so that it forms the outer boundary wall of the intermediate space 7. Due to its location, the heated absorbent glass sheet transfers heat in the intermediate space to the flowing exhaust air, from which the heat can be partially recovered.

The advantage of the present invention is that in winter the solar energy absorbed in the window during the heating season can be transferred in an even simpler way with the exhaust air, e.g. for use in heating a building. During the cooling season in summer, this energy can be stored for the heating season. The increase in the amount of air in the plant during the summer significantly enhances the recovery through the window.

Claims (1)

$ 4/002 Claim: A solar heat-absorbing window structure consisting of a standard window glass sheet (2) and a heat-absorbing thermal glass package (3) spaced from the window glass sheet and outside the room, at least part of the room exhaust air being adapted to pass through the first window. through the intermediate space (7) of the glass pane (2) and the thermal glass package (3), characterized in that the heat-absorbing glass plate (5) forms the outer boundary wall of the window glass panel and the thermal glass package intermediate space (7).
