Abstract
A vehicle exhaust heat recovery system includes a vapor compression type refrigeration circuit, a boiler to which the refrigerant is introduced from the refrigeration circuit and heated, and an expander for generating motive power by expanding the heated refrigerant. The refrigerant circulates in the refrigeration circuit. The boiler heats the refrigerant introduced therein using exhaust heat generated by the vehicle. The refrigerant that has been subjected to expansion is recycled to the refrigeration circuit.
