摘要： An expander-compressor unit (200A) includes a closed casing (1), a compression mechanism (2), an expansion mechanism (3), a shaft (5), and an oil pump (6). The shaft (5) couples the compression mechanism (2) to the expansion mechanism (3) so that power recovered by the expansion mechanism (3) is transferred to the compression mechanism (2). The oil pump (6) is disposed between the compression mechanism (2) and the expansion mechanism (3), and supplies an oil held in an oil reservoir (25) to the compression mechanism (2). An oil supply passage (29) is formed in the shaft (5) so that the oil discharged from the oil pump (6) can be supplied to the compression mechanism (2). A lower end (29e) of the oil supply passage (29) is located below an inlet (29p) of the oil supply passage (29) formed in an outer circumferential surface of the shaft (5).

摘要： A fluid machine (101) includes a first compressor (107) and a second compressor (108). The first compressor (107) has a first closed casing (111), a first compression mechanism (102a), an expansion mechanism (104), and a shaft (113). A first oil reservoir (112) is formed in the first closed casing (111). The second compressor (108) has a second closed casing (125) and a second compression mechanism (102b). A second oil reservoir (126) is formed at a bottom portion in the second closed casing (125). The first closed casing (111) and the second closed casing (125) are connected to each other by an oil passage (109) so that a lubricating oil can flow between the first oil reservoir (112) and the second oil reservoir (126). An opening (109a) of the oil passage (109) on a side of the first closed casing (111) is located above the expansion mechanism (104) with respect to the vertical direction. This configuration prevents the low temperature lubricating oil in a surrounding space of the expansion mechanism (104) and the high temperature lubricating oil in the second compressor (108) from flowing. Thereby, the heat transfer between the first compressor (107) and the second compressor (108) is suppressed.

摘要： There may be a case where, by simply coupling the first compressor (expander compressor unit) and the second compressor with an oil-equalizing pipe, the first compressor is not lubricated sufficiently, thereby decreasing reliability. The volumetric capacity (V1) of the first available oil space (130) of the first compressor (101) is set larger than the volumetric capacity (V2) of the second available oil space (140) of the second compressor (102). With this configuration, even if the oil level (S1) of the first oil sump (13) decreases in transition to a state of steady operation, it is possible to maintain a sufficient amount of oil in the first compressor (101), and thus high reliability as a fluid machine can be achieved.

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.

摘要： A sub-compressor (23) is provided between a compressor (22) and a power-recovery device (24). A refrigerant after preliminarily being compressed by the sub-compressor (23) is allowed to flow into the compressor (22). Since the sub-compressor (23) and the power-recovery device (24) have approximately the same temperature, heat transfer hardly occur therebetween. Heat transfer occurs between the compressor (22) at high temperature and the sub-compressor (23) at low temperature. However, even if the heat from the compressor (22) heats the refrigerant in the sub-compressor (23), the refrigerant discharged from the sub-compressor (23) is delivered to the compressor (22), and thus the temperature of the sub-compressor (23) scarcely increases.
