Abstract

Connected in parallel to an expander and a condenser of a Rankine cycle are n sets each including a different expander and a different condenser. Devices are provided for stopping operations of the expanders in sets connected in parallel, and a pressure sensor and a temperature sensor are installed respectively in an inlet and outlet of an evaporator. An electronic control unit sets or releases at least one of the operation stopping devices such that a measured value of the temperature sensor reaches a prescribed temperature value which is equal to or less than a thermal decomposition temperature of a refrigerant and which is set in advance, and the electronic control unit controls a rotational speed of a refrigerant pump such that a measured value of the pressure sensor reaches a prescribed pressure value set in advance.
