Abstract: PURPOSE: To make it possible to utilize waste heat of a temperature lower than a specific temperature by decomposing a molecular compound of an organic solvent accompanying an exothermic phenomenon or an endothermic phenomenon and an inorganic compound and circulating the produced organic solvent and re-dissolving the inorganic compound.  
     CONSTITUTION: When a predetermined quantity of an inorganic compound and an organic solvent having a boiling point of 100°C or less such as calcium chloride, and acetone are sealed in a heat exchange chamber 1, they react simultaneously with the sealing to produce a molecular compound. Therefore, when hot waste water such as a waste hot fluid of 100°C or less is passed through a fluid passageway 2, the molecular compound absorbs the heat of the waste hot fluid and decomposes, and the hot waste water is cooled, the organic solvent is stored via transport passages 4 and 4' in a storage chamber 5. A fluid to be heated is caused to flow to the fluid passage 2 to guide the organic solvent to the heat exchange chamber 1. Thus, the inorganic compound is dissolved, and the fluid to be heated rn the flowpath 2 is heated by the heat generated. By the repetition of these operations waste heat of a temperature of 100°C or less can be recovered and utilized.
