<P>PROBLEM TO BE SOLVED: To provide a heat utilizing material of a new material having high practicality, including a wide temperature range of -30 to 200°C and utilizable especially within the temperature range of 50-200°C which has not been achieved. <P>SOLUTION: The heat utilizing material is composed of an organic salt which is formed of an organic acid and an organic base and is a solid at normal temperature. The interaction between different kinds of molecules in the organic salt and reversible formation and dissociation energy thereof are utilized for the heat utilizing material. The magnitude of the interaction energy between the molecules can freely be selected by selecting the suitable combination of the molecules according to purposes. Since the molecules of a simple structure can be used as constituent molecules, the production is simple at a low cost. Since the formation and dissociation of the organic salt are reversible and the dissociated molecules can repetitively be used several times, the heat utilizing material can be used as a thermal storage medium of high heat storage volume. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
