PROBLEM TO BE SOLVED: To provide a power generation device composed of a closed cycle, and capable of being stably operated by preventing generation of cavitation of a liquid feed pump by stably controlling a supercooling degree.SOLUTION: In a closed cycle power generation device 1, a supercooler 4a is disposed in a supercooling passage 13 at a downstream side of a condenser 4, and a part of a cooling medium supplied to the condenser 4 is supplied to the supercooler 4a. A control portion 10 is provided to control an inlet of a pump 5 to a set supercooling degree ΔTsp by adjusting a flow rate of the cooling medium supplied to the condenser 4 and the supercooler 4a.SELECTED DRAWING: Figure 1 |
