    摘要: A refrigeration cycle apparatus (100) includes a first compressor (101), a second compressor (102), a radiator (4), an evaporator (6), and a pipe branching portion (30). The first compressor (101) has a first compression mechanism (1) and an expansion mechanism (5). The second compressor (102) has a second compression mechanism (2). The pipe branching portion (30) serves as a flow passage for introducing a refrigerant from the evaporator (6) to the first compression mechanism (1) and the second compression mechanism (2), respectively. The pipe branching portion (30) includes an inlet pipe (31) for receiving the refrigerant from the evaporator (6), a first branch outlet pipe (32) for introducing the refrigerant flowing into the inlet pipe (31) to the first compression mechanism (1), and a second branch outlet pipe (33) for introducing the refrigerant flowing into the inlet pipe (31) to the second compression mechanism (2). The inlet pipe (31) and the first branch outlet pipe (32) form an obtuse angle or an angle of 180° therebetween, and the inlet pipe (31) and the second branch outlet pipe (33) form an acute angle therebetween.

    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: 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).
