PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system for a vehicle provided with a device effectively suppressing superheat of refrigerant heated by a boiler in Rankine cycle at low cost. SOLUTION: Rakine cycle 10 is provided with a pump 11, a boiler 12, an expansion machine 13 and a condenser 3 commonly used with a refrigeration cycle 1, and fluorocarbon R134a which is refrigerant is circulated therein. One end of a bypass line 14 is provided on a suction side of the pump 11, another end of the bypass line 14 is connected to a delivery side of the pump 11. A flow rate regulating valve 15 is provided in the bypass line 14. A temperature sensing tube 17 detecting superheat of fluorocarbon R134a heated by the boiler 12 is provided at the outlet of the boiler 12, the temperature sensing tube 17 and the flow rate regulating valve 15 are connected by a connection pipe 16. Fluorocarbon R134a which is same as used refrigerant is filled in the connection pipe 16. COPYRIGHT: (C)2006,JPO&NCIPI
