PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of ensuring collecting refrigerating machine oil into a compressor if the refrigerating machine oil stagnates in a heat exchanger.SOLUTION: An oil level detection sensor 60 detects an oil level of refrigerating machine oil stored in a compressor 21. If the oil level is lower than a predetermined value, control means 100 controls a first solenoid valve 28a, a second solenoid valve 28b, and a third solenoid valve 28c to be opened or closed to close a part of a path. This makes it possible to increase a flow rate of refrigerant flowing in the path of an outdoor heat exchanger 23, to facilitate moving the refrigerating machine oil stagnant in the outdoor heat exchanger, and to ensure collecting the refrigerating machine oil into the compressor if the refrigerating machine oil stagnates in the outdoor heat exchanger. |
