(54) IMPROVVEMENTS IN OR RELATING TO SOLAR ENERGY COLLECTORS
(71) We, TEKNOrERM SYSTEMS AB, a body Corporate organized under the laws of Sweden, of Hans Michelsengatan 9,211 20 Mälmo, Sweden, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following state ment:- The present invention relates to a solar energy collector.
According to the invention there is provided a solar energy collector comprising a base plate; a heat insulating layer adjacent the base plate; an absorber adjacent the insulating layer; and a translucent panel which is spaced from the absorber thereby defining an air gap between itself and the absorber and which has regular or irregular patterning of the surface of the panel, the translucent panel comprising one or more members of U,V or M shape and having flanges which extend towards the absorber, the translucent panel being supported in a frame having recesses for the flanges of the or each said member. The ,use of patterning on ;the surface of the translucent panel gives rise to aesthetic effects of varying types, at the same time as it allows through substantially all of the solar radiation which impinges on the translucent panel.
Preferably the flanges abut against the absorber. Alternatively the solar energy collector includes another translucent panel be.- tween the first translucent panel and the absorber in which case the flanges of the first translucent panel abut against the absorber.
The aesthetic, translucent panel can be patterned on its surface with embossing or clouding or corrugation. Other surface patterns, for example, prism-shaped stripes in several directions of spherical holes of varying diameters can give rise to interesting and aestheically attractive optical effects.
The first translucent panel which is of at least one profiled member, a so-called glass profile, has structural properties.
In a preferred embodiment of the present invention the aesthetic panel consists of a plurality of preferably self-supporting, Uç shaped profile glass panels with structural properties. They all abut, with their flanges, tightly against the said other translucent panel of the solar energy collector or the absorber. Adjacent flanges in two adjacent profile panels abut tightly against each other and the gap between them is sealed by means of a suitable sealant. When the profile glass panels are put into place on the building site, they are preferably as long as the height or width of a complete ramp of several courses 'of the solar energy collector, on a roof or on an outer wall.They are, here, preferably mounted self-supporting above such a ramp of the solar energy collector with or without conventional translucent panels and are sealed against each other and along the outer edges of the ramp. It is not necessary that the flanges abut against the said other translucent panel or the absorber. Heat traps are, nevertheless, created by the combination of trans- lucent panels and absorbers-air gapsinteriorly of aesthetic glass profiles.
Alternatively, one or more such glass profiles can be applied as the outer glass with aesthetic properties in prefabrtcated complete collectors of varying, but manageable, i.e.
man-handlable-surface sizes.
The inner translucent glass panel can advantageously, comprise a glass profile. This construction is preferred for glass profiles of a width greater than 0.25 m. In this instance, the inner and outer glass paneIs lie each with their inner sides facing each other so that successively, the flange edges of one panel rest against the interior surfaces of the next panel.
In simpler, cheaper collectors of a low level of efficiency and in a highly efficient collectors with selective absorption surfaces the inner translucent panel can, however, be dispensed with.
The aesthetic, profiled panel can be of any given colour. Preferably it is produced from a normal ferriferous, common green alkali glass (window glass) or a non-ferriferous colourless alkali glass, or from a UV protection processed transparent plastic such as polycarbonate (for example, Lexaa (Re gistered Trade Mark)) or polyacrylate (for example; Plexiglass (Registered Trade
Mark)).
The glass profiles are self-supporting functional, economical and attractivebuilding elements. Their translucency, bending and compressive strength and facility of as sembly are very goo;d. They are used as translucent outer wails, partitions, roofs and windshields. Data from the marketed glass profile
Copilit (Germany): width 250 and 500mm length up to Sm., flange height 40 and 50mm, 4.75-8.80 kg/m, specific weight 2.2-2.3, glass thickness 5 mm, translucency 88%, sound-damping 27 dB, heart permeability 3.4-5.0 kcal/.h.m2.0C, Young modulus 800 000 kg/cm2.
Glass profiles of glass or plastics with aesthetic properties can be mounted in a hori zoin,tai direction. They can also be mounted vertically, with their 'length being the same as the height of the collector ramp. They are placed in the strong frame, for example, of aluminium with recesses for the flanges of the glass pares, and rest in the frame on a re- silient substrate, for example of neoprene rubber. They are retained at the top by a member provided on the structural frame, filled by a rigid cellular plastic which takes up the wind forces against the glass profile.
'Foamed plastics lists and resilient putty keep out moisture A resilient joint of a rubber list of, for example, neoprene, is applied between the flanges as a binder and insulator.
The invention will now be described in greater detail hereinbelow with reference to the accompanying drawing which shows a non-restrictive embodiment of the invention, in a perspective cross-section through a solar energy collector arranged in several courses, with an exteriorly provided group of glass profiled members having both aesthetic and structural properties, whose length is equal to the height of the ramp of solar energy collector.
The major parts of the solar energy ;ilec- for are a base plate 1, facing the wall or the roof, and a heat insulating layer 2, a solar energy absorber 3, an air gap 4, a translucent panel 5, air gaps 6, and aesthetic and struc- tural patterned glass profiled members 7 which form a main translucent panel and cover the other panel 5. A binder or sealant 8 bonds the flanges 9 and 10 of two adjacent glass profiled members 7 to each other and seals the gap between the flanges.The flange pair 9, d0 provides structural strength to the whole row of aesthetic glass profiled members 7 at;the same time as heat traps are formed by the translucent panel 5, the air gaps 6 and the glass profiled members 7. The large surface of aesthetic glass profiled members, divided only by the binder strands 8 iin the gaps between the glass profiled members 7, b; resistant against mechanical influence sad the effect of the outdoor climate if the glass profiled members are in a frame in the manner described above for mounting glass profiledi members.
The base plates of the collectors rest directly upon horizontal ridges 11 which are arranged in parallel and in turn rest upon a limited number of powerful roof truss frames 12 whose substantially vertical direction determines the inclination of the solar energy collector ramps Preferably, a translucent silicon-based binder is used as the sealant 8 between the flanges of the glass profiles.
The glass profiled members are preferably mounted erect, but it is also possible to mount - them in a recumbent, horizonta series.
The use of the patterning on the glass profiles givers the solar energy collector a pleasling aesthetic and architectonic appearance.
Although the translucency of the panel formed of the profiles is somewhat reduced from that which it would have been if plain glass had been used, the amount of light energy transmitted therethrough is not appreciably influenced.
