Abstract

Abstract In the system for accumulation of heat from solar radiant energy wherein the solar radiant energy is absorbed by heat-absorption means and transferred therefrom to a heat-transfer medium thereby to elevate the temperature of said heat-transfer medium an improvement is attained by using a plurality of heat-absorption members and arranging them in a series connection. These heat-absorption members are individually provided with selectively penetrating membranes capable of reflecting electromagnetic wave energies of the specific magnitudes of heat corresponding to the respective degrees of temperature of the heat-transfer medium. Since the heat-transfer medium is thus divided into a few different stages, the system disclosed herein permits highly efficient accumulation of high-temperature heat energies.
