That working medium is liquefied by the condenser 44 and stored in the container 45.
  • the impurity recovery step is performed after the working medium recovery step. Since the internal pressure of the system becomes negative by the working medium recovery step, in the impurity recovery step, the impurities in the liquid phase are recovered from the inside of the separator 34 in a state that the internal pressure of the separator 34 is maintained to be positive. Specifically, a valve 35 provided in a top of the separator 34 is opened, and respective on-off valves V6, V7 provided respectively on the upstream side and the downstream side of the separator 34 in the circulation flow path 22 are closed, thereafter the liquid extraction valve V4 is opened.
