| 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. | ||||||

Circuitry is provided having an input connected to the output of the sensor and an output connected to the solenoid valve. | ||||||

| PROBLEM TO BE SOLVED: To abate inverter loss in a motor-driven compressor and reduce the risk of electric leakage.SOLUTION: An inverter 27 includes a motor drive circuit 28 and a main control computer C1 for controlling the motor drive circuit 28. When a startup command is inputted, the main control computer C1 performs three-phase modulation control and calculates a discharge amount Qx of liquid refrigerant discharged from inside a motor housing 18 since the time point of start of the three-phase modulation control. When the calculated discharge amount Qx of a liquid refrigerant is less than a preset reference amount Qo, the main control computer C1 continues the three-phase modulation control. When the calculated discharge amount Qx of liquid refrigerant is equal to or larger than the preset reference amount Qo, the main control computer C1 switches from the three-phase modulation control to two-phase modulation control. | ||||||
