PURPOSE:To collect solar heat effectively by a method wherein a heat collector is provided at the moving place of the projection of collected beams which is changed in accordance with the altitude of the sun. CONSTITUTION:The heat collector 2 is provided in the fixed type paraboloidal reflecting mirror arranged in the direction of east and west while the solar beams of the winter solstice are collected at the surface A side of the collector 2 in the south side I of the reflecting mirror 1 and the same are collected from the surface B of the collector 2 in the north side J thereof. Further, passages of the beams are collected substantially at the middle of the collector 2 in the south and the north of the reflecting mirror 1 on the vernal equinox and the autumnal equinox. On the summer solstice, it is contrary and symmetry to the winter solstice and the passages of the beams are collected from the surface A in the north side of the mirror while from the surface B in the south side thereof. The beams, collected by such reflections of the beams into a band moving in the east and west direction in accordance with the altitude of the sun which is changed in each season, reciprocate from the surface A to the same B or from the surface B to the same A of the collector 2 all the year round and thereby being collected by the collector 2. |
