PURPOSE:To make the effective use of solar heat even when there is no sunshine and despite that a passive heat accumulation system is adopted, by a method wherein the titled wall member is made to have an outer surface having a selective absorbing property with respect to the sunlight and a latent heat accumulating material incorporated therein. CONSTITUTION:The solar heat accumulating wall member is so constructed that it is formed of a solar heat receiving surface 1 made of a copper plate attached with a black chrome selective absorbing film, a rear face plate 2 made of polyethylene and the heat accumulating material 3 consisting of sodium tenta hydrate sulfate and the transmissivity of the sunlight is controlled by varying the angle of a blind reflective plate 4 arranged ahead of the heat receiving surface. Thus, by using the above wall member, solar heat in daytime in winter is released into the room even after sunset, to thereby heat the room. Further, it is possible to prevent overheating by interrupting the sunlight by erecting the blind upright. |
