Abstract
A solar radiation reflector, including a parabolic-trough reflecting surface, transmits solar radiation in a general line reflection on an upright heat absorber during the winter and early spring months of low to moderate sun angles and a juxtaposed overhanging heat absorber above the upright absorber during summer high-sun angle periods for producing heated transfer medium from each absorber for use in domestic water supply and refrigeration. The reflector may tilt on azimuth to zenith lines for seasonal tilting actions and/or swing East to West to compensate for daily relative sun movement.
Claims8
Solar heat absorbing device comprising
- a. parabolic trough reflector means having its horizontally-oriented extent in straight lines and its vertical extent along a parabola, for focusing solar radiation into a narrow, linear area, which varies vertically at various seasons of the year mounted in a general horizontal position;
- b. upright, generally vertical, target means depending upwardly along the length of an edge of said reflector means in position to be impinged on by the linear area reflected radiation as well as receiving direct solar radiation, and an overhang target means depending from said upright target means extending over said reflector means;
- c. a plurality of lengths of fluid carrying pipes mounted on said target means to receive solar radiation and having inlet and outlet means for circulating fluid therethrough;
- and
- d. said target and carried pipes being blackened.
