Abstract

See full text

An exhaust heat recovery device provided with a Rankine cycle, capable of achieving improvements in start-up performance of the Rankine cycle and an efficient operation (actuation) of the Rankine cycle. An exhaust heat recovery device 1 that recovers and uses exhaust heat of an engine 10 includes: a Rankine cycle 2 including a heater 22, an expander 23, a condenser 24, and a pump 25; a bypass flow passage 26 that allows refrigerant to circulate while bypassing the expander 23; a bypass valve 27 that opens and closes the bypass flow passage 26; and a control unit 4. When starting up the Rankine cycle 2, the control unit 4 executes control to actuate the pump 25 with the bypass valve 27 open, and then to close the bypass valve 27 when a parameter indicating the condensation capacity of the condenser 24 becomes a predetermined value or more.
