Abstract
A solar collector comprises a fluid conduit 7 for conveying a fluid to be heated by the sun, an insulating structure 4 having a portion upon which the conduit is mounted, and a portion 3 of the insulating structure receiving a structural member of a building. The fluid conduit 7 may be a serpentine copper pipe attached to the rear of a metallic black absorber plate 6, which may be covered with glass cover 5 held in place in a water tight manner by an aluminium glazing bar 8 and weather strip 9. The structural member of the building may be a rafter of a roof and the portion 3 may be a rebate where the insulating structure 4 reduces in thickness and prevents significant modification of a roof structure when the solar collector is installed. The insulating structure 4 may be moulded or may be a rear enclosure and may span three or more rafters (fig 3). A flashing kit 12 may be provided and tucks into the glazing bar 8 to seal the panel to the roof.
Description
SOLAR COLLECTOR DEVICE
The present invention relates to solar collector devices, such as, for example, solar hot water systems.
Solar hot water systems are simple, proven technology and closer to economic parity with hydrocarbon fuels than many other renewable energy technologies. The focus of past development of products in this area has been primarily upon improvements to the efficiency of systems. Sadly, the result of these efforts has been to produce ever smaller improvements to the energy collected at the penalty of disproportionately higher prices.
Governmental subsidy schemes aimed at encouraging the uptake of renewable energy technology have only partially offset the poor economic case for these systems, and the penetration of the technology into common building practice has been low.
It is conventional to design a solar collector that is fitted to the house on top of the roof tiles. As well as producing a form that interrupts the roof line, this method requires the inlet and outlet pipes to pass through the roof covering.
Fitting conventional solar collectors is normally carried out by a specialist team with skills that are a blend of conventional trades.
Roof integrated designs are available, with two formats in common use. The first fits to the roof structure above the battens, replacing the tiles. This form typically projects above the roof line significantly. The second format is more visually appealing, sitting lower to the roofline but involves extensive modification to the roof structure, with the removal of rafters and boxing in to accommodate the panel, this approach is especially troublesome to apply to factory assembled space frame roof trusses.
Panels that are shaped to be fitted in between two rafters have been proposed, for example U54244355, US3987784. These designs follow conventional thought that the desired thickness of insulation must be
I
maintained at all costs. Consequently, when larger areas of solar collector are needed, several individual panels must be fitted side by side, at additional cost compared with a single larger panel.
It is an object of this invention to provide a design for a solar collector that is quick and economical to install without specialised training.
It is a further object of this invention to provide a design for a solar collector that has a low profile to the roof, and is more aesthetically integrated into the building.
The present invention provides a solar collector device according to claim 1 or claim 2.
Embodiments of the invention are defined in claims 3 to 6.
Hereunder follows a detailed description of embodiments of the invention, by way of example only, with reference to the accompanying drawings, in which: Fig. us a perspective view of a portion of a roof structure (shown without tiles, flashing kit and membrane for clarity), with a solar collector panel according to a first embodiment of the invention shown in position; Fig. 2 is a sectional view through a fitted solar panel along the line A-A shown in Fig 1; and Fig. 3 is a sectional view of a larger panel showing a second embodiment of the present invention spanning more than one rafter.
In the first embodiment of the invention, the solar collector panel 1 is of a width that corresponds to the distance between three rafters 2. The panel is secured to the rafters with brackets 13.
A glass cover 5 is arranged over a metallic black absorber plate 6 which has a serpentine copper pipe 7 attached to the rear. The cover glass 5 is held in an aluminium glazing bar 8 and a water tight seal provided by an EPDM weather strip 9.
The roofing tiles 11 are arranged over conventional roofing battens 10. A flashing kit 12 is provided and tucks into the glazing bar 8 to seal the panel to the roof covering in a weather tight way.
A moulded structural insulation 4 forms the rear enclosure of the panel.
Suitable materials for the insulation include, for example, lightweight concrete and foamed polymers such as PIR polyurethane and Phenol Formaldehyde.
The rear enclosure of structural insulation 4 is shaped at a location underlying the copper pipe (i.e. at a location down from the copper pipe in a direction perpendicular to the plane of the panel) to provide a region of reduced thickness that is of a size to accept a rafter 2.
This insulation at the rear of the panel is provided to prevent loss of the collected heat to the environment and to ensure that as much as possible is transferred to the circulating heat transfer fluid.
A second embodiment of the present invention as shown in Figure 3 is the same except that it is adapted to span more rafters.
This shaping of the external form of the solar panel to accept a rafter with a rebate allows closer integration of the solar collector to the roofline, without inconvenient modification of the roof structure.
The rebate reduces the thickness of the back insulation in a small area, and may result in a reduction of the efficiency of the panel when compared with a design without a rebate, but this is compensated for by the following benefits compared with conventional designs that maintain the thickness of the insulation: (a) Compared with designs that fit above the rafters it is of lower profile to the roof and therefore more visually integrated into the building.
(b) Compared with approaches that fit smaller modular panels in between the rafters it is more cost effective to manufacture and install.
(c) Compared with approaches that remove sections of the rafters and "box in", to accept the panel it is quicker and less costly to install.
In summary, the panels of these embodiments are shaped to fit across roofing members without requiring modification to the standard trussed rafter. The design is consequently rapid to fit and provides improved aesthetics compared to other solar collector panel designs, which project from the roof line.
The above detailed description of two embodiments of the present invention is provided by way of example only, and various modifications can be made to these embodiments without departing from the scope of the invention. One example of a modification is as follows. Although a moulded design for the structural insulation is particularly suited to introducing shape complexity without unduly compromising the cost, the moulded structural insulation of the above-described embodiments could be replaced with a rear enclosure made up of a moulded tray of polymer such as polyethylene or glass fibre reinforced resin, filled with insulation such as expanded perlite or glass wool.
The applicant draws attention to the fact that the present invention may include any feature or combination of features disclosed herein either implicitly or explicitly or any generalisation thereof, without limitation to the scope of any definitions set out above.
