摘要：Provided is a refrigerating cycle apparatus in which, even if large power is required to start up an expander, the expander may be started up by activating a compressor. An air conditioner including a first compressor (1) for compressing a refrigerant, an outdoor heat exchanger (2) for radiating heat of the refrigerant compressed by the first compressor (1), an expander (3) for decompressing the refrigerant that has passed through the outdoor heat exchanger (2), an indoor heat exchanger (4) in which the refrigerant decompressed by the expander (3) is evaporated, and a drive shaft (5) for recovering power that is generated when the refrigerant is decompressed by the expander (3) includes an on-off valve (6) which is provided between the expander (3) and the indoor heat exchanger (4) and controls movement of the refrigerant from the expander (3) to the indoor heat exchanger (4). After the first compressor (1) is started up to increase a pressure of the refrigerant in the expander (3) to a critical pressure or higher, the on-off valve (6) is opened and the expander (3) is started up by a dynamic pressure of the refrigerant.
