Abstract
A heat energy recovery device, which recovers heat energy of a heat medium by utilizing a Rankine cycle of a working medium, comprises a first heater, a second heater, an expander, an oil separation unit, a condenser, a working medium pump, and an oil-leading passage. When the height of a liquid level in the oil separation unitis less than a lower limit value, a control unitfirst performs a speed reduction control of the working medium pumpto reduce an inflow rate of a working medium into the second heater, and after a fixed period of time, performs an opening control for opening an on-off unit. By the opening of the on-off valve, oil Lin the second heateris led out to the oil separation unitthrough the oil-leading passage
