摘要： A refrigeration cycle apparatus (100A) includes a first compressor (101) that is an expander-compressor unit, a second compressor (102), and a controller (300). The controller (300) shifts, when an oil level 51 of a first oil pool (13) becomes equal to or lower than a specified level L, to an oil-equalizing operation in which a rotation speed of a first motor (12) is decreased only by a specified decrement and a rotation speed of a second motor (12) is increased by a specified increment, and an opening of a bypass valve (70) is increased so that a pressure or a temperature of a discharged refrigerant guided to a radiator (4) through a first pipe (3a) is kept approximately constant, and returns the rotation speeds of the first motor (11) and the second motor (12) as well as the opening of the bypass valve (70) to conditions before start of the oil-equalizing operation when a specified period of time has elapsed since the start of the oil-equalizing operation.
