Description

(1) TITLE OF THE
ROOFING MATERIAL AT LEAST GENERALLY CO-EXTENDING SOLAR WATER HEATING EQUIPMENT
(2) BACKGROUND TO THE INVENTION
Solar water heating systems as directly exposed to the heat of the sun have been known for a substantial time. The heating panels of such systems are in general situated above a roof of a structure which is so fitted. Some systems also Incorporate heating tanks (geysers) that are also fitted outside a roof. The panel or panels are under such conditions substantially exposed to the elements of nature, and especially wind that have the effect of reducing the efficiencies of such systems. Being so exposed furthermore involve such systems in frequent maintenance while th danger of freezing of water inside heating tubes along such systems require their jacketing in using anti-freeze substances to overcome this problem.
It is, amongst others, an object of this Invention to address this problem while however being of general application and not only dealing with conditions where tot measuring or the like is used.
{3} FIELD OF THE INVENTION
This invention relates to roof cover material replacement or involvement solar wafer heating equipment and to a method of its manufacturing and installation for use. While not so limited the Invention finds particular use when the equipment co-extends at least generally along roofing material.
{4} PRIOR ART DESCRIPTION
Fiat plate heat collectors are commonly used for the solar heating of water. Typically a copper heat exchange tube cluster is secured to a copper plate which is placed inside a sealed container having a glass cover facing the sun once in use. Water or anti-freeze situated inside the grill Is heated and reticulated to a geyser. In an alternative solar heating technique involves the exposure of an evacuated tube manifold grill consisting of jacketed borosiiicate glass tubes which is exposed to solar heat with heated water or anti-freeze flowing through the tubes to the geyser. Both the techniques described are of complicated configuration in also in some way or another involving jacketing to facilitate indirect anti-freeze reticulation components.

Referring to figures 1 , 3 and 6 to 9 of the drawings roof cover material replacement or involvement solar water heating equipment, according to the Invention, in the form of roofing material at least generally co extending solar water heating equipment, is generally Indicated by reference numeral 10.
Referring also to figures 2 and 4 the equipment 10 comprises a sheet like solar heat transfer promoting roofing type cladding member in the form a cladding sheet 12 having extensive heat transfer properties and that is formed with a piuraiity or laterally spaced channel defining formations 14 defining channels 16, channel closure means in the form of a channel straddling member by way of a straddling board 18 also serving as equipment support via which the cladding sheet 12 is supported and forming circumferentially channel enclosed zones 20 in conjunction with the channels 18, a plurality of heat exchange tubes22 of which one is mounted along each of the channels 16 of which the common ends 22.1 combine into common flow locations In the form of tube end manifolds 24 in combination with the heat exchange tubes 22 forming a heat exchange cluster 26 and an insulating member in the form of a thermal Insulation board 28 fitted to the outside of the straddling board 18.
To accommodate operative fitting of the equipment 10 without interfering with conventional roof; covering material the end regions 30 of the heat exchange tubes 22 as extending from opposite ends of the channels 15 are formed to extend away from the outer surface 32 of the cladding member 12 by being appropriately bent in causing the manifolds 24 to be situated at lower elevations in relation to the position of the cladding member 12 along roof covering means once the equipment Is fitted for use.
Enhancement of effective application of solar heat once the solar water heating equipment 10 is in operative use is dealt with by the channel enclosed zones 20 being circumferentially bordered by substance of extensive thermal conductivity In response to the Inner surfaces of the channel defining formations 14 and the straddling board 18 being fitted with a layer of material 34. Such material 34 is typically by way of pliable thin copper sheeting being of high thermal efficiency. In addition the channel enclosed zones 20 are filled with filler material also of extensive thermal conductivity in the form of composite masses of Intertwined malleable strands 38 In
circumferentially enclosing the heat exchange tubes 22. The masses can typically be in the form of tight-fitting braided copper or a tube sock knitted from thin copper strands. It can also be in the form of wiring with high thermal conductivity. The cluster 26 is naturally designed to cause the heat exchange tubes 22 to be of appropriate lateral spacing to fit the channels 16 while fitment of the heat exchange tubes 22 has the effect of operatlveiy mounting the cluster 26.
The heat exchange tubes 22 are typically positionably mounted by being of diameters that cause them to become sandwiched between the layer of material 34 along the Inner surfaces of the channels 16 and along the straddling board 18 once the latter is fitted to the cladding sheet 12. The tubes 22 are centrally maintained along the channels 16 by the filling action of the masses of intertwined malleable strands 38.
In a specific embodiment the outside surfaces of the sections of the layers of material 34 extending along the inner curvatures of the channels 16, thus facing the sun once the
equipment 10 is in use, are usefully coated with dark coloured paint to promote the ability towards both solar heat absorption and retention.
While not so limited the cladding sheet 12 is typically in the form of clear translucent materia such as Perspex or other similar material with extensive light translucency, heat penetration and good insulating properties while also having extensive impact resistance. Even corrugated galvanized roof covering can be used as cladding sheet 12 which is particularly useful when fitting the equipment 10 along corrugated galvanized roofing enabling the snug co-planar fitting of the cladding sheet 12 as replacing one or more standard roofing sheets.
The equipment 10 is naturally conventionally installed at a slope to achieve a thermo siphoning effect once in use. To this effect the manifold 24 situated in the lower position once installed serves as inlet manifold and the other more elevated manifold 24 as outlet manifold.
Where the equipment 10 is used under conditions where the temperature exposed to can drop below freezing a danger exist that the water situated in the heat exchange tubes 22can freeze up involving the risk of tube damaging by cracking on water expansion during freezing. In particularly referring to figure 5 this situation is accommodated for by fitting the equipment with heat exchange tube fitted independently run heating means in the form of heating coils 38fitted onto the heat exchange tubes 22 that are suitably connectable to become heated for
transferring such heat to the Interiors of the heat exchange tubes 22. Typically such coils can be in the form of electric resistance coils that thus become heated on the passing of electric current there-aiong. In a specific embodiment while not shown the coils 38 can be electrically coupled to cause the activation of electric current once a specific outside temperature is reached and vice versa.
It will be appreciated that the equipment 10 will often have to be custom designed but standardization may apply such as for example In the case of use in conjunction with
conventional corrugated galvanized roofing. Manufacturing of the equipment 10 is done by as a first step fitting the inner surfaces of the channels 18 and the inner surface of the straddling board 18 with the layers of material 34. Subsequently the cluster 26 Is fitted in response aligning and thus locating the heat exchange tubes 22 along their respective channels 16 in the process of or just prior to filling the channels 16 with the composite masses of intertwined malleable strands 36.
The heat exchange tubes 22 and thus cluster 26 are typically mounted by the heat exchange tubes 22 becoming sandwiched between the layer of material 34 along the inner surfaces of the channels 16 and along the straddling board 18. Their central positioning along their channels 1 are retained by the urging action of the composite masses of intertwined malleable strands 36 and so retained once the board 18 is fitted to the cladding sheet 12.
The straddling board 18 also serving as equipment support is subsequently secured to the cladding sheet 12 and the equipment 10 as thus far constructed finally fitted with the thermal insulation board28 as fitted to the outside surface of the straddling board 18.
While the equipment 10 is primarily separately manufactured and thus installed the possibility also exists that It can be manufactured in the process of equipment in roof installation thus in situ. This is especially the case where already installed cladding material is used to perform the function of the cladding sheet 12. In such case the procedure is essence the same as described.
In referring to figures 6 to 10 fitment of the equipment 10 to be at the ready for final installation by coupling along a water heating system (not shown) of a sloped roofed structure 40involves the removal of roof covering means 42to an adequate extent to accommodate its replacement by the solar water heating equipment 10. The equipment Is fitted to also guard against the Ingress of the elements of nature while naturally being fitted in an enclosed channel inwardly facing way in at least generally co-extending along the remainder of roof covering means. If the heating equipment 10 is manufactured in situ fitment obviously involves its stepwise
construction in essence as described above with the possibility that one or more members of the roof covering means 42 can in such case serve as cladding sheet 12.
In specifically referring to figures 6 to 8 in the case where the roof covering means 42 extends lengthwise channel profiled in the form of sheeting by way of a snug overlapping relationship as conventionally fitted to purlins 44 supported along rafters 46, the cladding sheet 12 is selected to form a complementary channel profiled snug overlapping relationship with the covering means to lie In a co-p!anar way there along. This is typically found in the case of galvanized corrugated iron or 1BR roof covering sheets but naturally not so limited. This is also typically the situation where one or more sheets of the roof covering means 42 can be used serve as cladding sheet 12 for the in situ manufacturing of the equipment 10.
in referring to figures 9 and lOin the case of covering means 42 In the form of cascading type overlapping roofing elements such as conventional tiling 48, roof covering tiles to the extent of accommodating the cladding sheet 12 are removed though only to such an extent that the uppe and side edge regions 50 and 52 respectively of the sheet 12 fit below adjacent tiling as shown at reference numeral 54 and thus against ingress of the elements of nature. Provision Is made to limit such ingress along the lower end 56 of the cladding sheet 12 by extending the section of roofing below the cladding sheet 12 down to a location roof discharge 58by way of at least one replacement roofing sheet 60 of similar shape and profile to the cladding sheet 12 in the latter forming a co-planar snug overlapping relationship with the upper edge region of the repiacemer sheeting. In such a way limitation the ingress of the elements of nature via the lower end of the cladding sheet 12 is also dealt with. When thus fitted to cascade type roof covering means the space between a tile 62 and the sheet 12 can be sealed by sealing means 64 while the cladding sheet 12 accommodates for its Independent securing to roof rafters such as by way of nails 66. it is an advantage of the Invention at least as specifically described that while fully exposed to the sun once installed It is less exposed to other elements of nature that would otherwise affect its efficiency while also requiring little maintenance. The simplicity of the equipment renders It very lightweight therefor adding little load to a roof cladding or structure while also omitting any separate anti-freeze loop reticulation that may under appropriate circumstances be required. The invention in effect involves an extension to plumbing reticulation, and a minor roof cladding modification, rather than an added device.
