Waste heat recovery system with low temperature heat exchanger

Abstract:

Systems and methods are disclosed to recover waste heat from an engine fluid with a heat exchanger subsystem that includes a heat exchanger. The heat exchanger subsystem is thermally coupled to a working fluid and the engine fluid, so the waste heat from the engine fluid is transferred to the working fluid. The engine fluid is bypassed from the heat exchanger in response to a heat exchanger bypass condition.
