Abstract
To improve the exhaust heat recovery efficiency, a compressor includes a heat exchanger for cooling a gas, coolant, water, or oil heated by the compressor during compressor operation by heat exchange with a working fluid, for circulating the working fluid of a Rankine cycle. The Rankine cycle is implemented by the heat exchanger, an expander, a condenser, and a circulating pump to circulate the working fluid through the cycle.
