Abstract
The heat accumulating material of this invention comprising three components of calcium chloride (CaCl.sub.2), urea [CO(NH.sub.2).sub.2 ] and water (H.sub.2 O) can have varied temperatures of heat accumulating and heat releasing between 15.degree. C. and 29.5.degree. C. by varying the proportion of said three components, and also has a large latent heat. Hence, much expectation can be placed on it as a heat accumulating material for air conditioning. Moreover, by adding BaFeO.sub.3-x (0.ltoreq.x.ltoreq.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.
