ABSTRACT OF THE DISCLOSURE The heat accumulating material of this invention comprising the three components calcium chloride (CaCl2), urea [CO(NH2)2] and water (H2O) can have varied temperatures of heat accumulation and heat release between 15°C and 29.5°C by varying the relative proportions of said three components, and also has a large latent heat. Hence, it is advantageous for use as a heat accumulating material for air conditioning. Moreover, by adding BaFeO3-x (0?x?0.53) as a nucleating agent to the above-mentioned composition, supercooling can be greatly decreased and wider application of this heat accumulating material becomes possible.
