ABSTRACT:
An air conditioner for an auxiliary heating apparatus performs an auxiliary heating of a refrigerant flowing through a refrigerant circuit. The air conditioner is provided with a first auxiliary heat exchanger having a built-in first hydrogen-occluding alloy and hydrogen and a second auxiliary heat exchanger having a built-in second hydrogen-occluding alloy and hydrogen, wherein a temperature/hydrogen pressure characteristic of the second hydrogen-occluding alloy is different from that of the first hydrogen-occluding alloy. The air conditioner is further provided with hydrogen piping for circulating hydrogen between the first auxiliary heat exchanger and the second auxiliary heat exchanger, and a fan for heating the second auxiliary heat exchanger. Selector valves are also provided for circulating the refrigerant discharged from a compressor, when the axuiliary heating of the refrigerant is not performed. The refrigerant is circulated from the first auxiliary heat exchanger, to an indoor heat exchanger, to an expansion valve, to an outdoor heat exchanger and then to the second auxiliary heat exchanger. The selector valves are also for circulating the refrigerant discharged from the compressor, when the auxiliary heating of said refrigerant is performed, in the order of the indoor heat exchanger, the expansion valve, the outdoor heat exchanger, and the first auxiliary heat exchanger.
