Definitions
- the invention relates to solar heating systems, and more particularly, to a solar heating system useful for heating air within a structure.
- windows In cold climates, windows typically represent area of heat loss in a structure or leak and allow cold air to radiate in or enter a room. Such cold air radiation or leakage increases the cost of heating a structure, such as a home, and reduces the comfort level of its occupants. While windows visually enhance a space, they represent the largest area of heat loss in a structure due to its low unit thermal resistance value (commonly known as R-value). Old and leaky windows have also traditionally been sealed with various types of weather stripping and other materials. Thus, a need exists for a system to effectively heat an interior space while reducing heat loss and leakage through a typical window area.

- the corrugated panel may include channels to foster upward air flow.
- the corrugated panel may include plurality of aligned channels.

- Such a configuration enhances the upward flow of heated air against the corrugated panel thereby increasing heat transfer from the heated corrugated panel.
- This configuration also allows the corrugated panel to capture more solar energy as it is closer to being positioned orthogonal to sun rays, which are at a lower angle in the winter months.
- the solar heating system may also include a bottom cover at the lower inlet gap or a top cover at the top of the device, or both, to prevent the reverse flow of cold air during cold evening hours when the solar panel is not exposed to the sun.

Abstract
A solar heating system for heating air beside a window is disclosed. The solar heating system effectively heats air beside a window in a room of a structure through use of one or more solar panels positioned to be heated by the sun and to transfer that heat to surrounding air via convection in moving air. In at least one embodiment, the solar panel may be a corrugated panel having at least one channel. The solar panel may be positioned such that as the solar panel is heated by the sun, heat is transferred from the solar panel to surrounding air via convection. The solar panel may be configured such that an upward flow of air forms when the air is heated, thereby creating a natural, warm air flow without need of a fan or other such device.
Description
- This application claims priority to U.S. Provisional Patent Application No. 61/455,316, filed Oct. 19, 2010, the entirety of which is incorporated herein.
- The invention relates to solar heating systems, and more particularly, to a solar heating system useful for heating air within a structure.
- In cold climates, windows typically represent area of heat loss in a structure or leak and allow cold air to radiate in or enter a room. Such cold air radiation or leakage increases the cost of heating a structure, such as a home, and reduces the comfort level of its occupants. While windows visually enhance a space, they represent the largest area of heat loss in a structure due to its low unit thermal resistance value (commonly known as R-value). Old and leaky windows have also traditionally been sealed with various types of weather stripping and other materials. Thus, a need exists for a system to effectively heat an interior space while reducing heat loss and leakage through a typical window area.
- A solar heating system for heating air beside a window is disclosed. The solar heating system effectively heats air adjacent to a window in a room of a structure through use of one or more heat absorbing solar panels. In at least one embodiment, the solar panel may be a corrugated panel having at least one channel. The solar panel may be positioned such that as the solar panel is heated by the sun, heat is transferred from the solar panel to surrounding air via convection. The solar panel may be configured such that an upward flow of air forms when the air is heated, thereby creating a natural, warm air flow without need of a fan or other such device. In one particular application, the solar heating system is suited for installation adjacent to an inside surface of a window, such as resting on a window sill. In at least one embodiment, the solar heating system may be used with existing, already installed windows to enhance energy efficiency of the windows.
- The solar heating system may be formed from a solar heater support structure and one or more solar panels supported by the solar heater support structure. In at least one embodiment, the solar panel may be one or more corrugated panels. The corrugated panel may include one or more channels. A cover panel may be supported by the solar heater support structure adjacent to the corrugated panel to foster upward airflow and to increase the interior aesthetics of the solar heating system. The solar heating system may also include an inlet gap between a bottom edge of the corrugated panel and a bottommost surface of the solar heater support structure such than when installed, the inlet gap exists between the bottom edge of the corrugated panel and an adjacent structure to feed cool air beside the window to the solar heating system.
- The corrugated panel may include channels to foster upward air flow. In at least one embodiment, the corrugated panel may include plurality of aligned channels. The channel may be positioned generally vertical. The corrugated panel may be positioned at an acute angle relative to the cover panel such that a lower inlet formed in the at least one channel between the cover panel and the at least one corrugated panel is larger than an upper outlet formed in the at least one channel between the cover panel and the at least one corrugated panel. Such a configuration enhances the upward flow of heated air against the corrugated panel thereby increasing heat transfer from the heated corrugated panel. This configuration also allows the corrugated panel to capture more solar energy as it is closer to being positioned orthogonal to sun rays, which are at a lower angle in the winter months.
- The solar heating system may also include a bottom cover at the lower inlet gap or a top cover at the top of the device, or both, to prevent the reverse flow of cold air during cold evening hours when the solar panel is not exposed to the sun. Such covers may be hinged or strapped to the lower inlet gap or top of the device to prevent the downward flow of cold air from the bottom of the solar heating system.
- The solar heater support structure may be formed from a first leg on a first side and a second leg on a second side that is on a generally opposite side of the at least one corrugated panel. The first and second legs may be attachable to a window or its surrounding structure. The first and second legs may each include a recess in a lower rear edge of each leg to facilitate installation of the solar heater structure in place to accommodate typical window trim design. A releasable connector may be attached to the solar heater support structure to releasably secure the solar heater support structure in place for use. The releasable connector may be, but is not limited to being a hook and loop connector and an adhesive.
- The solar heating system may also include a cover panel having a communication surface on an outer surface of the cover panel. The communication surface may be a dry erase outer surface or a push pin board. In other embodiments, the cover panel may include a peg board on an outer surface. The cover panel may also include one or more shelves on an outer surface. The cover panel may also include a mirrored outer surface. In other embodiments, the cover panel may be painted or wallpapered, or both to match the surrounding interior design. The cover panel may also support other items, such as, but not limited to pictures, hooks, racks and the like.
- An advantage of the solar heating system is that cold air radiating or leaking through windows in cold climates is passively heated to reduce the heating load of the room in which the southern facing windows exist.
- Another advantage of the solar heating system is that the system is mounted on the inside of windows, thereby eliminating an issues that are likely to crop up with exterior mounting, such as rejection by a homeowners association board or an architectural review board.
- Yet another advantage of this invention is that the solar heating system provides free heat when installed without having to be turned on.
- Another advantage of this invention is that the solar heating system reduces utility costs.
- Still another advantage of this invention is that the solar heating system is a renewable energy source.
- Another advantage of this invention is that the solar heating system extends the life of conventional heating equipment.
- Yet another advantage of this invention is that the solar heating system is safe because the solar heating system does not use flammable fuels or electricity to produce the free heated air.
- Another advantage of this invention is that the solar heating system may be sold fully assembled and ready to install in an existing window, new or old.
- Still another advantage of this invention is that the solar heating system is easy to install or uninstall because the solar heating system is thin and lightweight.
- Another advantage of this invention is that the solar heating system does not deteriorate or become functionally obsolete over time.
- These and other embodiments are described in more detail below.

Theacute angle 66 may be between about one degree and about 20 degrees. Such a configuration enhances the upward flow of heated air against the metal plate thereby increasing heat transfer from the heated metal plate. This configuration also allows thesolar panel 14 to capture more solar energy because thesolar panel 14 is positioned closer to a position of being orthogonal to the sun rays. - The
solar heating system 10 may also include aninlet gap 68 positioned between thebottom edge 38 of thecorrugated panel 34 and abottommost surface 70 of the solarheater support structure 20 such than when installed, theinlet gap 68 exists between thebottom edge 38 of thecorrugated panel 34 and an adjacent structure, which may be, but is not limited to being, awindow sill 18. When thesolar heating system 10 is installed adjacent to awindow 12, solarheater support structure 20 positionssolar panel 14 above thewindow sill 18, thereby creating theinlet gap 68 through which air from the cavity next to thewindow 12 flows. As such, theinlet gap 68 provides a route for cold air to flow from the cavity next to thewindow 12 into theheating chamber 72 positioned between thesolar panel 14 and thecover panel 46. In another embodiment, theinlet gap 68 may be formed from a plurality of orifices in thesolar panel 14 at thebottom edge 38. - The

solar heating system 10 may also include abottom cover 82 at thelower inlet gap 68 or atop cover 76 at the top of thesolar panel 14, or both, to prevent the reverse flow of cold air during cold evening hours when the solar panel is not exposed to the sun. Thebottom cover 82 may cover theinlet gap 68. Thebottom cover 82 may be formed from any appropriate material. Thebottom cover 82 may or may not be attached to the solarheater support structure 20. In at least one embodiment, thebottom cover 82 may be rotatably coupled to the solarheater support structure 20 with a connector, such as, but not limited to, a hinge to prevent the downward flow of cold air from the bottom of the solar heating system. Thetop cover 76 may cover theupper outlet 64. Thetop cover 76 may be formed from any appropriate material. Thetop cover 76 may or may not be attached to the solarheater support structure 20. In at least one embodiment, thetop cover 76 may be rotatably coupled to the solarheater support structure 20 with a connector, such as, but not limited to, a hinge to prevent the downward flow of cold air from the bottom of the solar heating system. - During use, the
solar heating system 10 may be used to provide convective heating. In at least one application, thesolar heating system 10 may be used to provide solar heating of air to a room which includes awindow 12. For instance, thesolar heating system 10 may be placed in close proximity to thewindow 12. As such, solarheater support structure 20 may be attached to thewindow 12 or to components near thewindow 12. In such a position, anouter heating chamber 86 is formed between thesolar panel 14 and thewindow 12 such that air is channeled between thewindow 12 and thesolar panel 14. The solarheater support structure 20 may be rested on thewindow sill 18 and releasably attached to the trim that frames out thewindow 12. Thereleasable connector 74 may be used to releasably attach the solarheater support structure 20 to the trim around thewindow 12. As shown inFIGS. 1 and 4 , theouter surface 78 of thesolar panel 14 may be a dark color and should be directly exposed to sun coming through thewindow 12. Theouter surface 78 may be positioned as close as possible to being orthogonal o the sun rays for maximum output. Any blinds or other obstructions should be removed. Thesolar heating system 10 should be used with southerly facingwindows 12 in the northern hemisphere and northerly facingwindows 12 in the southern hemisphere.Windows 12 with eastern and western exposures may be used, but will produce less warm air. - Cold air enters the
heating chamber 72 through theinlet gap 68 between thebottom edge 38 of thesolar panel 14 and thewindow sill 18. The air is heated as it contacts thesolar panel 14. As the air is heated, the air rises through theheating chamber 72 and is exhausted into the room through theupper outlet 64. The sun may heat thesolar panel 14 to temperatures as high as about 140 degrees Fahrenheit. - The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of this invention. Modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of this invention.
