Abstract (en)
[origin: WO2007132326A1] An exhaust heat recovery system (10) includes an exhaust heat recovery heat exchanger (18) in which heat is transferred from exhaust gas discharged from an internal combustion engine (12) to an engine coolant for cooling the internal combustion engine (12), and a heat pump system (22) for recovering exhaust heat of exhaust gas. The heat pump system (22) includes a refrigerant circulation passage (24) for circulating CO2 refrigerant, a heat-absorbing heat exchanger (32) in which heat is transferred from exhaust gas to the CO2 refrigerant, and a heat-releasing heat exchanger (28) in which the exhaust heat recovered by heat transfer to the CO2 refrigerant in the heat-releasing heat exchanger (32) is recovered.
