摘要： An expander-integrated compressor (5A) has a compression mechanism (21) for compressing a refrigerant and an expansion mechanism (22) for expanding the refrigerant. The compression mechanism (21) is located above the expansion mechanism (22) inside a closed casing (10) and shares a rotating shaft (36) with the expansion mechanism (22). An oil pump (37) is provided at the lower end of the rotating shaft (36). The oil pump (37) is immersed in oil in an oil reservoir (15). Usually, the oil is placed in the oil reservoir (15) in such a manner that the oil level (OL) is located above a lower end portion (34e) of a vane (34a) of a first expansion section (30a). More preferably, the oil is placed in such a manner that the expansion mechanism (22) is immersed in the oil. An oil supply passage (38) for guiding the oil to the compression mechanism (21) is formed inside the rotating shaft (36). A suction port (37a) of the oil pump (37) is provided below the lower end portion (34e) of the vane (34a).

摘要： An integrally formed vane (301) is disposed slidably in a vane groove (205a) of a first cylinder (205) and a vane groove (206a) of a second cylinder (206). A cut-out (301a) with a width substantially equal to the thickness of an intermediate plate (304) is provided in the vane (301), which is divided by this cut-out (301a) into a first vane portion (301b) whose leading end makes contact with a first piston (209) at its leading end and a second vane portion (301c) whose leading end makes contact with a second piston (210). This configuration allows the first vane portion (301b) to be pushed toward the first piston (209) side by the pressure difference acting on the second vane portion (301c) and makes it possible to keep a contact state between the first vane portion (301b) and the first piston (209), even when no pushing force toward the first piston (209) side that results from the pressure difference acts on the first vane portion (301b).

摘要： A refrigeration cycle apparatus includes a first compressor 1, which is an expander-compressor unit, and a second compressor 2. A first compression mechanism 11 of the first compressor 1 and a second compression mechanism 21 of the second compressor 2 are disposed in parallel with each other in a refrigerant circuit 30. The refrigeration cycle apparatus is provided with an injection passage 6. A controller 7 controls a first motor 12 of the first compressor 1 and a second motor 22 of the second compressor 2, and an opening of an injection valve 61. The controller 7 performs an optimizing operation for the opening of the injection valve. In the optimizing operation, the opening of the injection valve 61 is brought closer to a fully closed state or closer to a fully opened state while a pressure or a temperature of a discharged refrigerant guided to a radiator 4 through a first pipe 3a is kept approximately constant.

摘要： A refrigeration cycle apparatus includes an expander-compressor unit (1) having a first motor (12), a second compressor (2) having a second motor (22), and a controller (7). The controller (7) determines the target rotational frequency F1 of the first motor (12) and the target rotational frequency F2 of the second motor (22) for a start-up operation, and determines whether the opening X of an injection valve (61) should be in a fully opened state or in a fully closed state during the start-up operation, based on an outside air temperature and other factors. Then, the controller (7) performs the start-up operation by controlling the rotational frequencies f1 and f2 of the first motor and the second motor to be the determined target rotational frequencies F1 and F2 while maintaining the opening X of the injection valve in the fully opened state or in the fully closed state.

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.
