摘要： The expander-compressor unit 70 includes the closed casing 1, the expansion mechanism 4 disposed in the closed casing 1 so that a surrounding space thereof is filled with the oil, the compression mechanism 2 disposed in the closed casing 1 so as to be positioned higher than the oil level, the shaft 5 for coupling the compression mechanism and the expansion mechanism 4 to each other, and the oil flow suppressing member 50 disposed in the surrounding space of the expansion mechanism 4 so that the space 55a filled with the oil is formed between the expansion mechanism 4 and the oil flow suppressing member 50. Thereby the flow of the oil filling the inner reserving space 55a is suppressed, and thus, heat transfer from the high temperature oil to the low temperature expansion mechanism can be reduced.

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： 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.
