Title:
WASTE HEAT RECOVERY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/169375
Kind Code:
A1
Abstract:
This waste heat recovery device recovers waste heat generated by a combustion engine that outputs a rotational driving force. A first heat exchanger transfers heat from a cooling fluid that cools the combustion engine to a refrigerant. A second heat exchanger transfers heat from exhaust gas discharged from the combustion engine to the refrigerant. An expander is linked to the combustion engine in such a manner that a driving force is transmitted from the combustion engine. A bypass refrigerant flow channel branches off from a refrigerant flow channel and bypasses the first heat exchanger. A refrigerant flow rate regulator regulates the flow rate of the refrigerant in the bypass refrigerant flow channel. A temperature detector detects the temperature of the refrigerant in the refrigerant flow channel upstream from the expander. A control unit controls the flow rate regulation state of the refrigerant flow rate regulator on the basis of information detected by the temperature detector.
