摘要： A refrigeration cycle apparatus 100 includes a low-pressure compressor 113, a high-pressure compressor 101, a radiator 103, a gas-liquid separator 107, an expansion valve 109, an expander 105 and an evaporator 111. The low-pressure compressor 113 and the expander 105 are coupled by a shaft 116, and the low-pressure compressor 113 is driven using power recovered by the expander 105 from a refrigerant. The low-pressure compressor 113 and the high-pressure compressor 101 are serially connected by an intermediate-pressure flow path 114. The gas-liquid separator 107 and the intermediate-pressure flow path 114 are connected by the reciprocating flow path 115. The reciprocating flow path 115 is configured to allow the refrigerant to circulate bidirectionally. It is possible to regulate the refrigerant flow rate in the reciprocating flow path 115 by controlling the opening degree of the expansion valve 109.

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.

摘要： An expander-integrated compressor 200A includes a closed casing 1, a compression mechanism 2, an expansion mechanism 3, a shaft 5, an oil pump 6, and a heat insulating structure 30A. The oil pump 6 is disposed between the compression mechanism 1 and the expansion mechanism 3, and draws, via an oil suction port 62q, an oil held in an oil reservoir 25 to supply it to the compression mechanism 2. The heat insulating structure 30A is disposed between the oil pump 6 and the expansion mechanism 3, and limits a flow of the oil between an upper tank 25a, in which the oil suction port 62q is located, and a lower tank 25b, in which the expansion mechanism 3 is located, so as to suppress heat transfer from the oil filling the upper tank 25a to the oil filling the lower tank 25b.
