Abstract
An exhaust heat recovery device, with a Rankine cycle for recovering and using exhaust heat of an engineincludes: a Rankine cycleincluding a heater, an expander, a condenser, and a pump; a bypass flow passageallowing the refrigerant to circulate while bypassing the expander; a bypass valveopening and closing the bypass flow passage; and a control unit. When starting up the Rankine cycle, the control unitexecutes start-up control of the Rankine cyclein which the pumpis actuated with the bypass valveopen and then the bypass valveis closed. Furthermore, the control unitrepeatedly executes the start-up control when the pressure difference between the high-pressure side and the low-pressure side of the Rankine cycleafter closing the bypass valvedoes not reach the start-up completion determination value within a predetermined time.
