摘要： A thermal energy recovery device of the present invention includes a heater that evaporates a working medium by a heat medium, an expander into which the working medium flowing out from the heater flows, a power generator that recovers expansion energy of the working medium expanded in the expander, a condenser of a condensing unit that condenses the working medium flowing out from the expander, and a pump that feeds the working medium condensed in the condenser to the heater. A connection portion between the condenser and the pump has a connection end portion connected to an inflow port of the pump, a bent portion bent upward from the connection end portion, and a standing portion extending upward from the bent portion so that the working medium in a gas phase is suppressed from coming into the pump even in an environment where vibration is generated.

摘要： A compressing device of the present invention comprises a compressor, a heat exchanger, an expander, a power recovery unit, a condenser, a pump, a bypass flow passage for bypassing the expander, and a bypass valve. When a bypass condition for allowing a working medium to circulate through the bypass flow passage is satisfied, the bypass valve is caused to be opened, thereby allowing the working medium to circulate between the heat exchanger and the condenser through the bypass flow passage. As a result, a compressed gas discharged from the compressor is cooled by the working medium in the heat exchanger. This configuration makes it possible to cool the compressed gas by the working medium in the heat exchanger regardless of operation conditions of the expander.

摘要： A heat energy recovery device 1, which recovers heat energy of a heat medium by utilizing a Rankine cycle of a working medium, comprises a first heater 2, a second heater 3, an expander 4, an oil separation unit 12, a condenser 6, a working medium pump 7, and an oil-leading passage 10. When the height of a liquid level in the oil separation unit 12 is less than a lower limit value, a control unit 16 first performs a speed reduction control of the working medium pump 7 to reduce an inflow rate of a working medium into the second heater 3, and after a fixed period of time, performs an opening control for opening an on-off unit 11. By the opening of the on-off valve 11, oil L1 in the second heater 3 is led out to the oil separation unit 12 through the oil-leading passage 10.
