    摘要： The present disclosure relates to a vapour-compression circuit 400, 400' for circulating a working fluid. The vapour-compression circuit 400, 400' comprises: a first compressor 402A, a second compressor 402B, a suction line 418, a discharge line 412, an oil separator 510 and an oil distribution network 520. The first compressor 402A and the second compressor 402B are provided in respective first 411A and second 411B parallel branches between the suction line 418 and the discharge line 412. The oil separator 510 is located along the discharge line 412 and is configured to remove oil from working fluid in the discharge line 418. The oil distribution network 520 is configured to re-supply oil removed from the working fluid by the oil separator 510 to a first oil supply location 522A, 522A' at or upstream of the first compressor 402A along the first branch 411A, and also to a second oil supply location 522B, 522B' at or upstream of the second compressor 402B along the second branch 411B.

    摘要： A refrigerating apparatus comprising: a main circuit through which a refrigerant flows; a plurality of compressors; a non-return valve; a condenser; a receiver; a first expansion valve; an evaporator; an injection flowpath; an solenoid valve disposed upon the injection flowpath; a fluid level detection unit that detects the amount of refrigerant stored inside the receiver; and a control unit. The control unit closes the first expansion valve prior to stopping the compressors and closes the solenoid valve at the point that the fluid level detection unit has detected that the amount of fluid component inside the receiver has reached a predetermined upper value.
