A vapor compression refrigerator having a refrigeration cycle ( 200 ) is disclosed. In a Rankine cycle ( 300 ), a refrigerant is circulated through a pump ( 310 ), a heater ( 320 ), an expander ( 330 ) and a condenser ( 220 ) in that order, and power is recovered by the expander 330 due to the expansion of the refrigerant from the heater ( 320 ). In a host gas cycle ( 500 ), on the other hand, the inlet of the compressor ( 210 ) can be connected from a point between the pump ( 310 ) and the heater ( 320 ) by a switching path ( 510 ) having a first restricting portion ( 510 ), the refrigerant is circulated by the compressor ( 210 ) through the heater ( 320 ) and the switching path ( 510 ) in that order, and the heater ( 320 ) exhibits the function of heating a heat generating device ( 10 ).
