摘要： A thermal energy recovery device includes: a circulation line having an evaporator, an expander, a condenser, and a pump; a power recovery machine; a first on-off valve; a thermal energy introduction line configured to introduce a gas phase working medium into a post-expansion space; a second on-off valve; and a control unit. Until an evaporation condition that a liquid phase working medium accumulated in the post-expansion space has reached an amount equal to or smaller than a reference amount is met, the control unit closes the first on-off valve and opens the second on-off valve, and drives the pump in a state where the expander is stopped, and when the evaporation condition is met, the control unit opens the first on-off valve and closes the second on-off valve, and drives the expander.

摘要： A power generation apparatus according to the present invention includes: an induction generator; a switch that opens or closes an electrical connection path connecting the induction generator to an electrical path in which an alternating current of a predetermined frequency flows; a control unit that controls the opening and closing state of the switch; and an expander that rotationally drives the induction generator by a working medium supplied thereto. In order to suppress a starting current generated when starting the induction generator while suppressing an increase in cost, the control unit closes the switch after the working medium is supplied to the expander so that the expander starts to rotationally drive the induction generator.
