As an electric power, or as an auxiliary to the driving force of the second cycle refrigerant pump, it passes through the second cycle expander and passes through the first cycle expander using the still hot refrigerant. The reduced-pressure, low-temperature refrigerant is heated by a heat exchanger, the driving force required for the first-cycle compressor is reduced, passed through the second-cycle expander, and the first-cycle reduced-pressure, low-temperature The second cycle refrigerant pressurized by the refrigerant pump and the first cycle compressor increased in temperature and pressure by the heat exchange with the refrigerant became low temperature. Combined air conditioner that generates power by the driving force of the expander by the second cycle refrigerant that has become high temperature and high pressure due to heat exchange with the medium, and assists in driving the first cycle compressor and the second cycle refrigerant pump A combined air conditioner using different refrigerants that match the characteristics of the first cycle refrigerant and the second cycle refrigerant.
