Definitions

  • GI. 7 is an explicit form of Eq. 1.
  • the angle ⁇ of the rib cross section is determined so that ⁇ ⁇ ⁇ / 2- ⁇ G is satisfied. If ⁇ ⁇ ⁇ / 2- ⁇ -arcsine [sin ( ⁇ M - ⁇ ) / n] If what is the case for large deviations of the window orientation from the south direction and / or long sun blocking times, a sawtooth profile with certain angles is provided on the undersides of the prismatic ribs (Fig. 3).
  • This prismatic glass pane also offers better glare protection against direct solar radiation at the workplace level near the window compared to conventional insulating glass panes, but does not lead to improved illumination of the room depth. The effort to finish this disc increases significantly if a sawtooth profile is required.
  • a window glass for vertical windows is also known (Edmonds lR, 1993. Performance of laser cut light deflecting panels in daylighting applications. Solar Energy Materials and Solar Cells 29, 1-26 ).
  • This system can be implemented, for example, with the help of acrylic glass plates, into which narrow parallel incisions are made - for example with laser beams (Fig. 5).
  • the cross sections of these ribs can have the shape of a rectangle or a parallelogram with the aspect ratio h / b which does not deviate significantly from the rectangular shape.
  • a beam penetrating the rib depends on the point of impact, occurs Angle ⁇ of the beam and the aspect ratio h / b and the shape of the glass rib cross-section, after none, one or more reflections on the Back of the glass rib again.
  • Fig. 6 shows three possible examples Ray profiles in the plane of the rib cross-section for three different angles ⁇ . It can be seen that some of the rays - depending on the angle ⁇ - move is redirected at the top, while the rest of the rays move in the original direction maintained. In fact, the proportion of those diverted upwards fluctuates Radiation depending on the direction of the incident radiation from 0 to 1; this also applies if the glass rib cross-section is a parallelogram.
  • this system For vertical windows, however, which essentially facing north - in the southern hemisphere: facing south is this system, which also has good transparency, well suited for improving the lighting of deep rooms with daylight.
  • this system is used as a ceiling light in the shape of a pyramid compared to a corresponding ceiling light made of conventional insulating glass capable of both the radiant heat in one Significantly reduce space as well as for improved illumination of the room with daylight.
  • German patent application DE A1 E04D003-35 describes a window glass which uses horizontal, mirrored profile bars in the space between two glass panes (Fig. 7) to reflect direct solar radiation in summer and in winter - deflected upwards - in to let the room enter.
  • the radiation from the covered or clear sky that is incident at flat to medium angles can penetrate into the room, while the radiation from the covered or clear sky that is incident at medium to steep angles is reflected.
  • the aim of this window glass is to control the absorption of radiant heat so that as little energy as possible can enter the room in summer and as much as possible in winter, and by deflecting the incident light against the usually white ceiling - compared to conventional insulating glass - a better one Illumination of deep rooms with daylight.
  • This system was simulated using the RADIANCE computer program for a test room with a south-facing window (Moeck M., 1998. On daylight quality and quantity and its application to advanced daylight systems. Journal of the Illuminating Engineering Society Winter 1998, 3-21 ) and also examined in terms of measurement technology (Aizlewood ME, 1993. Innovative Daylighting Systems: An experimental evaluation. Lighting Research and Technology 25, 141-152) and compared with other systems. It was found that this system, apart from potential glare effects, can offer the desired sun protection and also helps to even out the brightness in deep rooms. However, it significantly reduces the amount of light and energy entering rooms, not only in summer but also in winter, so that it must be assessed in each application whether the system has the desired energy-saving effect. The system is somewhat transparent.
  • this window glass is less than that of a window with a blind system. Because of the exclusively horizontally oriented profile rods, this system, like the prismatic glass already described according to French patent no. 8017364, is only suitable for windows which are oriented essentially to the south. If the sky is clear and there is direct sunlight, the glare effect changes over time due to the specularly reflecting profiles.
  • a fixed prism system (Fig. 8) is also known (Bartenbach, C., 1986. New daylight concepts. Technology at Building 4, BR Germany), which consists of two prismatic lenses and an inside mirror. The two prismatic disks and the inner mirror are arranged so that they form a cavity with an isosceles cross section.
  • the outwardly projecting prismatic lens has the task of reflecting the direct solar radiation, which can penetrate up to a maximum angle of the sun, and to let the intense radiation from the sky pass through the zenith area and direct it onto the inside mirror.
  • the transmitted radiation is directed by the interior mirror onto the second prismatic lens, which has the task of directing the radiation upwards against the white ceiling of the interior and thus producing the most uniform, glare-free illumination of deep rooms with daylight.
  • each of the prisms of these panes is vapor-coated with a specularly reflecting aluminum layer.
  • This system was also examined using the RADIANCE computer program for a test room with a south-facing window (Moeck M., 1998. On daylight quality and quantity and its application to advanced daylight systems. Journal of the Illuminating Engineering Society Winter 1998, 3- 21). It was found that this system can provide the desired, almost complete sun protection and that it prevents glare from direct sunlight. But apparently it hardly helps to even out the brightness in deep rooms.
  • this system acts as a light and energy dimming device in summer and in winter quite evenly - ie without a clear, seasonal effect.
  • This system is not transparent. Because of this and because of the outwardly projecting prismatic lens, it is essentially suitable for skylights in combination with the usual, transparent sun protection windows arranged underneath. Because of the exclusively horizontally oriented prismatic ribs, this system, like the systems already described above, is only suitable for windows which are oriented essentially to the south.
  • a system is also known (European patent application 833 01687.6, publication 0092322 A1), which consists of two disks with horizontal prismatic ribs (Fig. 9).
  • the prismatic ribs of the two disks which all have identical cross-sections in the shape of a right-angled triangle, face each other and are interlocked so that there is only a small air gap between the two disks.
  • the cross section of the prismatic ribs which is designated as "characteristic”, is determined by the prism base angle ⁇ and the areas C A , f A and s A (Fig. 10).
  • the characteristic cross section of the prismatic ribs can be used as a substitute for the actual configuration for the examination of the beam path, since the parallel shift of the front surface interface A A only causes an insignificant parallel shift of the beam path.
  • this system has the advantage that it is transparent in the lower angular ranges, but the disadvantage that it reflects the radiation in the middle and upper angular ranges only insufficiently or not at all. The sun protection effect of this system is therefore insufficient.
  • a similar system is described in International Patent Application PCT / GB94 / 00949, publication WO 94/25792.
  • the subject of this patent application is a disc system consisting of two discs with interlocking, prismatic ribs of rectangular cross section. It is an improvement and further development of the system described in European patent application 833 01687.6, consisting of two vertical disks with interlocking, horizontal prismatic ribs. To avoid the essential shortcomings of the system described in European Patent Application 833 01687.6, the prism surfaces s A of the outer prismatic lens A are provided with a reflective coating that is as perfectly reflective as possible and the prism surfaces sB of the inner prismatic lens B are provided with a coating that is as completely diffusely reflective as possible (Fig. 12).
  • the refractive index n of the pane material was set to 1.5, which corresponds to the refractive index of conventional window glass and acrylic glass.
  • c f is a partial area of the surface c A a prismatic rib (Fig. 18) through which passes the portion of the radiation which falls and after penetration across the interface a A directly f upon the prism area A, if ⁇ 2 ⁇ ⁇ , pervades the system. This proportion depends on the respective angle ⁇ 1 of the incident radiation, is equal to the ratio of the two areas c f / c A and is to be called the visible area ratio SV.
  • the transition is one Beam from one transparent medium to another in different Refractive index associated with reflection losses.
  • the total internal reflection within a medium is practically lossless, so that a beam even with a beam path with multiple internal total reflections only Loses energy due to absorption in the medium.
  • the lost through absorption Energy of a beam in common window glass and especially in acrylic glass is still relative due to the fact that even with multiple internal total reflections short path of the beam in the medium is very small, if not negligible.
  • the prism base angle is in the range 45 ° ⁇ 5K ⁇ 58 ° for systems that reflect radiation with 4 or 5 interface contacts - in short 5K systems - selected.
  • the prism base angle is in the range 68 ° ⁇ 7K ⁇ 71 ° for systems that reflect radiation with 4 or 7 interface contacts - in short 7K systems - selected.
  • the prism base angle is in the range 74 ° ⁇ 9K ⁇ 77 ° for systems that reflect radiation with 4 or 9 interface contacts - in short 9K systems - selected.
  • Prisms based on 11 or more interface contacts need not to be examined because of the resulting sun blocking times are too small for use in a sun protection system.
  • the room has the shape of a cuboid 6 m wide, 10 m long and 3 m high.
  • the room is rectangular Assigned x, y, z coordinate system. The width of the room extends from the yz plane in the direction of the x axis, the length of the space from the zx plane in the direction of the y axis and the height of the room from the xy plane in the direction of the z axis.
  • the surfaces are 6 times wide, in the length 10 times and the height divided 3 times, so that there is a total of 216
  • the whole Broad side of the room in the + y direction is a transparent window area, while the other side surfaces, the floor and the ceiling surface are radio-opaque Are wall surfaces.
  • the floor surface has a degree of reflection of 0.2 (roughly corresponding to a dark carpeting), the side walls have a reflectivity of 0.5 to 1 m height, while the side walls over 1 m high and the ceiling surface has a reflectance of 0.8 (like a white coat of paint).
  • the calculations are each for a latitude of 50 ° carried out.
  • the degree of reflection of the earth's surface outside the test area is always set to 0.2.
  • the internal temperature of the test room becomes independent of the day time and the season set equal to 20 ° C.
  • Fig. 27 shows the illuminance of the sensor surfaces for vertical, after Window surfaces facing south-east with insulating glass, sun protection glass or Prismatic glass on December 20 at 12 p.m. with cloudy skies depending represented by the depth of the room.
  • the illuminance has for insulating glass and sun protection glass the typical steeply sloping course with increasing Room depth.
  • the illuminance is close to the window significantly lower than for insulating glass and sun protection glass, but they From a room depth of about 3 m, slightly higher than the illuminance for sun protection glass is.
  • the prismatic glass the tendency is towards a more balanced one Room lighting recognizable, even if the illuminance for all three Glazes differ little in the depth of the room and for that most requirements are too low.
  • Fig. 28 shows the illuminance of the sensor surfaces for vertical, after Window surfaces facing south-east with insulating glass, sun protection glass or Prismatic glass on June 20 at 12 o'clock with clear skies depending on the Depth of space shown.
  • the illuminance has for insulating glass and sun protection glass also the typical steeply decreasing course with increasing Room depth, but at a very high level.
  • the illuminance for that Prismatic glass near the window is significantly lower than the very high illuminance for insulating glass and sun protection glass, although also that of the window surface closest sensor area not directly from the very high standing sun is illuminated.
  • the prismatic glass offers significantly improved comfort near the window. The tendency towards a more balanced Room lighting for the prismatic glass can also be seen.
  • the Illuminance near the back wall of the test room is for that Prismatic glass larger than for the sun protection glass and approaches the illuminance for the insulating glass. However, in this case the Illuminance in great depth for all three glazing all requirements.
  • Fig. 29 the illuminance of the sensor surface is that of the rear wall closest to the test room, for vertical, southeast facing Window surfaces with insulating glass, sun protection glass or prismatic glass on December 20 shown with overcast sky depending on the time of day. It can be seen that the temporal course of the illuminance in the vicinity of the Back wall of the test room for the prismatic glass throughout the day approximately in the middle between the corresponding illuminance curves for insulating glass and sun protection glass.
  • the illuminance of the sensor surface is that of the window surface closest to the test room, for vertical, southeast facing Window surfaces with insulating glass, sun protection glass or prismatic glass on the 20th June depicted with clear skies depending on the time of day. It's closed recognize that the sensor surface for window surfaces with insulating glass or sun protection glass receives direct sunlight until about 11 a.m. and therefore has enormously high illuminance. Also in case air conditioning therefore ensures a pleasant average temperature of the room the stay near the window with window surfaces with insulating glass or sun protection glass without additional sun protection measures, e.g. External blinds, practically impossible. In comparison, the excellent sun protection effect of the prism glass particularly clearly. Also the time course the illuminance near the window area of the test room during the rest of the day the prismatic glass is well below the corresponding one Illuminance curves for insulating glass and sun protection glass.
  • Fig. 31 are the daily radiated into the window areas and from the amount of heat given off for vertical, southeast exposure aligned window surfaces with insulating glass, sun protection glass or prism glass depicted depending on the anniversary.
  • Prismatic glass in winter is almost as much heat radiated as in the usual Insulating glass and significantly more heat is radiated than in the sun protection glass, while in the prismatic glass in summer considerably less heat than in the usual insulating glass and also significantly less heat than in the sun protection glass is irradiated.
  • the amount of heat given off by the prismatic glass is slightly larger than that of the year round Amount of heat given off by sun protection glass.
  • the heat transfer coefficient can be However, reduce the prism glass.
  • the energetic advantages of the prismatic lens system compared to the usual one Insulating glass and sun protection glass are clear. Unless air conditioning is used, the prismatic lens system in comparison a significant increase over the usual insulating glass and sun protection glass thermal comfort during the summer and transitional periods. In some buildings, the use of the prismatic lens system the waiver of an air conditioning system or the replacement of the air conditioning system enable by a ventilation system. As example calculations show with simultaneous use of the prismatic lens system and an air conditioning system in a building - especially in buildings with large window areas - the additional costs of equipping the building with prismatic panes compared to equipment with standard insulating glass or sun protection glass quickly due to the lower cost of the smaller air conditioner and compensated by the reduced energy costs.
  • An analytical examination of the pane system shows that small deviations of the current geographical latitude ⁇ , the current window inclination angle v and / or the current window alignment angle ⁇ from the data for which the pane system is designed and the inclination angle ⁇ of the longitudinal axis of the ribs to the horizontal in the window plane, the prism base angle ⁇ and the sun blocking time d G has been determined, are possible without significantly impairing the function of the system.
  • the sun protection function and the energetic effect of the window system are completely given if, for example, the actual window alignment angle ⁇ deviates from the target value of this angle by up to ⁇ 7.5 °.
  • This insensitivity of the pane system with regard to slight deviations from the design data can be used to restrict the manufacture of the pane system to a certain number of types, with which the entire range of applications of the pane system can be covered.
  • the two prismatic disks A and B shown in Fig. 12 have identical dimensions of the cross-section of the characteristic prismatic ribs.
  • the geometry of the prismatic disc B arises from the geometry of the prismatic disc A by rotation with the angle ⁇ about the longitudinal axis of the prismatic rib (y P axis).
  • the glass bodies of the two prismatic panes are therefore identical in construction and can therefore be produced with the same tool.
  • the function of the system requires that the two prism surfaces f A and f B are separated from one another by a narrow gap Z and that the prism surface s A is provided with a coating that is as perfectly reflective as possible and the prism surface s B is provided with a layer that is as completely diffusely reflective as possible is. There must be no air gap between the reflective layer and the glass material of the respective prism surface in order to avoid additional reflection losses of the rays on these surfaces due to the exit from the glass body and the re-entry into the glass body.
  • the reflective properties of the reflective layers should also be changed as little as possible over the long term by environmental influences, in particular by solar radiation.
  • the gap Z should be as narrow in relation to the prism surface s A or s B as is technically possible, but should be reliably present under all ambient conditions (outside temperature, inside temperature, air pressure, wind loads, dead weight with inclined windows), i.e. also a temporary contact between the prism surfaces f A and f B should not occur.
  • no gap is required between s A and s B , but, if present, should also be as narrow as possible in terms of production technology, so that the non-transparent portion of the prism surface of f A or f B remains as small as possible.
  • the prism surfaces s A or s B must therefore be sufficiently large so that the relative gap width of Z is approximately negligibly small and the function of the system is not impaired.
  • the height of the prismatic ribs and thus the dimensions of the prism surfaces are chosen to be as small as possible in order to keep the thickness and thus the weight and the cost of the system as low as possible.

  • the two prismatic disks A and B must be firmly and permanently connected to each other. Between the prism surfaces f A and s A and f B and s B there must be a rounded transition in the concave, right-angled corners in order to avoid excessive notch stresses at these points.
  • the gaps between the prism surfaces f A and f B and, if applicable, between the prism surfaces s A and S B must be carefully sealed off from the ambient air in order to permanently and safely prevent the ingress of dust and moisture.
