Abstract:
1. A waste heat utilizing system for an automotive vehicle comprising: a waste heat collecting cycle for collecting waste heat from an internal combustion engine and having an expansion device for generating rotational driving force from the collected waste heat; a refrigerating cycle having a compressor device for compressing a refrigerant; and a power transmitting means driven by an outside driving source and operatively connected to the compressor device to rotationally drive the same, wherein the expansion device is operatively connected to the compressor device to rotationally drive the same, the waste heat collecting cycle has the expansion device, a condenser, an electrically-driven refrigerant pump, and a heating device, the internal combustion engine is water-cooled and has a passage of the engine coolant for the heating device and an electrically-driven water pump being placed in the passage to supply the engine coolant to the heating device, and the waste heat utilizing system further comprises a control unit which operates both the electrically-driven water pump and the electrically-driven refrigerant pump to operate the waste heat collecting cycle when the internal combustion engine is stopped.
