摘要： A refrigeration system includes first and second compressors and an oil separator. The oil separator includes an inlet for receiving refrigerant and oil from the first compressor, a refrigerant outlet, and an oil outlet. The oil separator separates the oil from the refrigerant. A portion of the oil separator below a horizontal plane intersecting the refrigerant outlet collects separated oil and has a volume equal to a first compressor oil supply. The first compressor oil supply is greater than or equal to 100% and less than or equal to 250% of a first compressor initial oil charge. The first compressor receives oil from the oil outlet when an amount of oil in the portion is less than or equal to the first compressor oil supply. The second compressor receives oil from the refrigerant outlet when the amount of oil in the portion is greater than the first compressor oil supply.

摘要： Disclosed is a scroll compressor, comprising: an orbiting scroll (50A, 50C) having an orbiting scroll end plate (54A) and an orbiting volute (56C) formed on one side of the orbiting scroll end plate, and a fixed scroll (40A, 40B, 40C) having a fixed scroll end plate (44A, 44B) and a fixed volute (46C) formed on one side of the fixed scroll end plate. The fixed scroll and the orbiting scroll match each other in order to form a series of compression cavities therebetween, the series of compression cavities comprise a central compression cavity (C1) and a middle compression cavity located on a radial outer side of the central compression cavity, and the middle compression cavity comprises at least a set of a first middle compression cavity (C2) and a second middle compression cavity (C3); and a fluid channel (300, 300C1, 300C2) selectively communicating with a discharge area is provided between the first middle compression cavity and the second middle compression cavity, and the first middle compression cavity directly communicates with the second middle compression cavity by means of the fluid channel.

摘要： Provided is a scroll compressor, comprising a compression mechanism (CM) and a valve assembly (200), wherein the compression mechanism (CM) is provided with a vent (V), and the valve assembly (200) is used for selectively opening and closing the vent (V). The valve assembly (200) comprises a valve plate (220) and at least one valve piece (224), wherein the valve plate (220) comprises at least one valve orifice (222); and the valve piece (224) is configured to selectively open and close the valve orifice (222). The scroll compressor further comprises a guide passageway (L), wherein the guide passageway (L) is provided with a first port (LI) communicating with the valve orifice (222) and a second port (L2) communicating with the exhaust opening (V). The valve assembly and the compressor can significantly prolong the service life of the valve piece, and can provide good guidance for a fluid discharged from the compression mechanism, thereby significantly reducing the resistance of venting and the pressure drop in the fluid, and significantly improving the effect of venting.
