PURPOSE:To provide the titled heat-accumulating agent composed of a mixture of halides having the same number of crystallization water molecules at normal temperature, producible at a low cost and having high solubility. CONSTITUTION:The objective heat-accumulating agent is composed of a mixture of halides having the same number of crystallization water molecules at normal temperature or thereabout and consisting of a combination of a relatively inexpensive chloride (e.g. CaCl2) and a bromide having high solubility (e.g. CaBr2). The molar ratio of the halide having high solubility is preferably 0.4-0.65 based on the sum of both halides. |
