PURPOSE:To accumulate the heat by the high conversion efficiency in a heat conversion process from a high temperature heat-accumulative tank to a low temperature heat- accumulative tank by using a low boiling poit organic compound for the refrigerant of a heat-accumulative refrigeration cycle, and for an active medium of the Rankine cycle. CONSTITUTION:A heat-accumulative refrigeration cycle A using a organic compound, the boiling point of which is less than 30 deg.C, and the property of which is able to form a hydrate crystal having a critical decomposition point of 5 deg.C-18 deg.C, is composed of a low temperature heat-accumulative tank 1 keeping a water or a aqueous solution L in its inside, and a nozzle 8 supplying said low temperature boiling point organic compound into a water L under fluid state. Further, said heat-accumulating refrigeration cycle A is provided with a compressor 3 compressing the vapor of the low temperature boiling point organic compound produced by the low temperature heat-accumulating tank 1, and a condenser 5 liquifying a compressed vapor. The liquified low temperature boiling point organic compound 6 is introudced again to the nozzle 8. On the other hand, the Rankine cycle B using said organic compound for the active medium produces the organic compound vapor by a high temperature heat-accumulator 9, a turbine 21 is driven by said vapor, then the compressor 3 of the refrigeration cycle A is operated. |
