PURPOSE:To increase the magnification of condensation and the rate of heat collection, by providing a shaft, provided at the end of a solar heat collecting plate, with a rotary concave reflex mirror of small curvature. CONSTITUTION:Rotary concave reflex mirror 2 is provided at upper end O1 of heat collecting plate 1 as an axis, and it is set at a prescribed angle (20 deg. in Tokyo) to the horizon. At need, rotary concave mirror 2 is fitted slanting at a prescribed angle (53 deg. in Tokyo) at lower end O2 of heat collecting plate 1 as an axis. The amount of heat collection in a year is maximized by installing heat collecting plate 1 with the normal direction agreeing with the south center direction of the Vernal Equinox Day and Autumnal Equinox Day. In comparison with only heat collecting plate 1, the amount of heat collection in a year is increased three times or more. |
