PROBLEM TO BE SOLVED: To provide highly safe and versatile method and system for converting refrigerant circulation power for converting heated high pressure supercritical refrigerant energy into rotation power by a non-power circulation system at a low cost with a low noise.SOLUTION: The system comprises a supercritical refrigerant generating part 1 having a plurality of heating furnaces 1a-1d for discharging a high pressure supercritical refrigerant, a power converting mechanism 3 for converting the supercritical refrigerant into rotation power with an expansion turbine 31, a condenser 4 for liquefying a refrigerant gas from an expanding machine, a storage tank 2 for storing a liquefied refrigerant, and a circulation channel linking these components for circulating the refrigerant. The supercritical refrigerant is supplied substantially continuously to the expanding machine by repeatedly performing successive changing over of a cooling cycle for having the refrigerant flow in for cooling down the heating furnaces and heating cycle for heating the supercritical refrigerant to discharge the refrigerant. |
