<P>PROBLEM TO BE SOLVED: To provide a waste-heat regenerating system in which the temperature elevation of a boiler and a hydraulic fluid can be sufficiently prevented even when an engine runs and an output from an expander is not needed. <P>SOLUTION: A waste-heat regenerating system 100 is provided with: a Rankine-cycle circuit 30 comprising a pump 32, a boiler 34, an expander 36 and a condenser 38; a temperature sensor 37 that detects a temperature of a hydraulic fluid at the downstream exit of the boiler 34; a bypass channel 31 that bypasses the expander 36; an on/off valve 33 provided in the bypass channel 31; and a controller 50. The controller 50 closes the on/off valve 33 when the engine 10 runs and the output from the expander is not needed. The controller also makes the pump 32 adjust the flow rate thereof so as to bring the temperature of the hydraulic fluid to or below a first prescribed temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
