Definitions

  • the invention relates to a glazing panel which may be used in the construction of skylights, windows, glasshouses and the like.
  • the invention is concerned with a glazing panel which may be employed to reduce or increase the amount of solar energy which passes through the panel.
  • a glazing panel comprises two spaced translucent substantially parallel sheets, a plurality of substantially parallel spaced reflective slats positioned between the sheets, each slat extending the length of the panel, means to space the sheets and to hold the slats in position so that they are substantially equally spaced across the width of the panel and are angularly inclined with respect to the sheets.
  • the invention will be described in relation to the use of the glazing panel in a skylight in a horizontal roof.
  • the glazing panel is also horizontal and is removably mounted in the roof aperture so that it can easily be withdrawn therefrom and replaced.
  • Figure 1 is a cross-sectional view of the glazing panel and illustrates how the glazing panel should be positioned during summer with the slats pointing away from the sun (South) ;
  • Figure 2 is a cross-sectional view of the glazing panel and illustrates how the glazing panel should be positioned during winter with the slats pointing towards the sun (North) . Description of the Preferred Embodiment:
  • the glazing panel comprises two spaced transparent parallel planar sheets 12 and 14 separated by a plurality of transparent spaced parallel ribs 16 extending between the two sheets 12 and 14 in planes perpendicular to the planes of the sheets.
  • the ribs are spaced across the width of the glazing panel and each rib extends along the length of the glazing panel.
  • each cell located side-by-side across the width of the glazing panel, each cell extending along the length of the glazing panel with its four sides being formed by the two sheets 12 and 14 and by two adjacent ribs 16.
  • the cross-section of each cell is square or rectangular.
  • the sheets 12 and 14 and the ribs 16 are preferably made of a clear plastics material such as a polycarbonate resin or an acrylic resin and the double skinned plastics section may be formed in one piece by extrusion.
  • each cell 18 Positioned diagonally in each cell 18 is a reflective planar slat 20.
  • Each slat 20 is reflective on both its major surfaces and may be of polished aluminium.
  • the slats are positioned so as to be in substantially parallel planes at an angle of 40° to the planes of the sheets. That angle was chosen because it had been found that the highest percentage of winter solar penetration occurs when the sun's altitude is 40°.
  • the glazing panel In summer, the glazing panel is positioned so that the slats 20 point away from the sun (i.e. slats point south) . That is, from the glazing panel the sun is in a direction which is substantially perpendicular to the planes of the slats 20. Rays from the sun falling on the glazing panel also impinge on a slat 20 because, in view of the transverse dimension of the slats 20 and their spacing, they combine to present to radiation from the sun a substantially continuous reflective surface over the entire glazing panel.
  • the glazing panel is rotated in its own plane through 180 and thus the slats 20 point towards the sun (i.e. slats point north) . That is, from the glazing panel the sun is in a direction which is substantially parallel to the planes of the slats 20. Rays from the sun falling on the glazing panel pass through the spaces between adjacent slats. In other words, the slats 20 have negligible effect on radiation from the sun and the glazing panel transmits substantially all of the solar energy falling thereon.
  • the results of the tests may be as follows -
  • the tests were conducted at Noon and the percentages differ as the direction of the sun in relation to the panel changed throughout the day. The results show differences due to changes in latitude and the time of the year.
  • the glazing panel positioned so that the slats point north towards the sun, there was only a very small reduction in solar transmission compared to a skylight extrusion without slats.
  • the glazing panel positioned so that the slats point south, there was a substantial reduction in solar transmission.
  • the glazing panel of the invention may be employed effectively to permit the transmission of solar energy through a skylight during winter and be reversed during summer to reduce substantially the transmission of solar energy.
  • the skylight In the case of a pitched roof, the skylight should be located in that part of the roof with a northerly aspect.
  • the glazing panel When the glazing panel is mounted at an angle to the horizontal, the inclination of the slats 20 with respect to the sheets 12 and 14 should be adjusted to the optimum angle to reduce solar energy penetration during summer and allow maximum solar energy penetration during winter.
  • the slats 20 need not be flat but may be curved. In this case all slats have the same curvature so they may be positioned in parallel relation.
  • the reflective aluminium slats may be given a matt white finish.

Abstract

Un panneau vitre convenant a des chassis vitres, des fenetres et serres est realise de telle maniere qu'en le disposant selectivement par rapport a la direction du soleil, la quantite d'energie solaire transmise au travers du panneau puisse etre reglee. Le panneau vitre comprend une piece transparente d'extrusion de deux feuilles paralleles (12 et 14) espacees par des rainures (16) pour former une pluralite de cellules (18) disposees cote a cote et une pluralite de lamelles (20) reflechissantes paralleles (20) disposees en diagonale dans chaque cellule. Ainsi que la figure l'illustre, les lamelles (20) sont orientees dans une direction differente de celle du soleil de maniere a permettre au panneau de reduire la transmission d'energie solaire mais peuvent etre redisposees de telle maniere que les lamelles (20) soient orientees vers le soleil pour permettre une transmission de l'energie solaire.
