Abstract
Abstract Heating system comprises solar heating panel, black fluid, and structure for selectively circulating black fluid through heating panel. Panel includes enclosure having light-transmitting upper surface, and light-transmitting conduit is closely arranged in serpentine fashion within enclosure. Reflective surface is positioned under conduit arrangement. In use, black fluid circulating through conduit arrangement absorbs solar energy, and in non-use black fluid is drained from conduit arrangement whereby reflective surface functions to reflect rays of sun away from heating panel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
A heating system comprising a solar heating panel, black fluid, and means for selectively circulating the black fluid through the heating panel, the panel including an enclosure having a light-transmitting upper surface, a light-transmitting conduit within the enclosure closely arranged in serpentine fashion through which the black fluid selectively circulates, and a reflective surface directly under the conduit arrangement substantially completely masked by that arrangement when black fluid is circulated therethrough and substantially completely unmasked when no black fluid is circulated therethrough, and wherein the enclosure is sealed, and the interior thereof is at least partially filled with a gas having a thermal conductivity lower than that of air.
Claim 2
Dependent Claim
109 words
A heating system comprising a solar heating panel, black fluid, and means for selectively circulating the black fluid through the heating panel, the panel including an enclosure having a light-transmitting upper surface, a light-transmitting conduit within the enclosure closely arranged in serpentine fashion through which the black fluid selectively circulates, and a reflective surface directly under the conduit arrangement substantially completely masked by that arrangement when black fluid is circulated therethrough and substantially completely unmasked when no black fluid is circulated therethrough, and wherein the enclosure is sealed, and the interior thereof is at least partially filled with a gas having a thermal conductivity lower than that of air.
Claim 3
Dependent Claim
29 words
A heating system as in claim 1 wherein the light-transmitting upper surface of the enclosure includes downwardly depressed ribs therein to reduce circulation of the gases within the enclosure.
Claim 4
Dependent Claim
15 words
A heating sytem as in claim 1 wherein the gas is a fluorinated hydrocarbon gas.
