PURPOSE:To miniaturize heat accumulator while improving heat collecting and accumulating efficiency by a method wherein the heat accumulator is composed of two inner and outer tanks and one of the tanks is filled with latent heat accumulating material and the other with water. CONSTITUTION:A copper inner tank 10 of small capacity provided in an outer tank 8 filled with sensible heat accumulating material 9 is filled with the latent heat accumulating material 11. The heat collected by a collector 3 is transmitted to latent heat accumulating material 11 through a closed circulating course, a heat exchanger 2. When the fuzing temperature of this heat accumulating material 11 reaches about 60-80 deg.C, the heat is transferred from the inner tank 10 to the outer tank 8 through a heat exchanger 12 that is a closed circulating circuit arranged in the outer tank 8. Naphthalene, stearate, polyethylene glycol, etc. are used for the latent heat accumulating material. |
