A compressor includes a housing, and a drive assembly, a compression assembly and an expansion assembly which are provided in the housing; the compression assembly is connected to and driven by the drive assembly, and is configured to perform multi-stage compression on a refrigerant under drive of the drive assembly; the expansion assembly is connected to the drive assembly and is configured to expand the refrigerant compressed by the compression assembly. A refrigeration cycle device includes the above-mentioned compressor.

Compressor and refrigeration cycle device

Some embodiments of the present disclosure provide a compressor and an air conditioner with the compressor. The compressor includes: a first compression part, a second compression part, an intermediate cavity and an intermediate passage. Refrigerant discharged from the first compression part enters the intermediate cavity. The intermediate passage communicates with the intermediate cavity and an inner cavity of the second compression part. A bottom port of the intermediate passage is located at a bottom of the intermediate cavity, and air supplement refrigerant and/or the refrigerant discharged from the first compression part are used to convey accumulated oil in the intermediate cavity to the inner cavity of the second compression part. When only the refrigerant is used to convey the accumulated to the inner cavity of the second compression part, at least a part of the intermediate passage is located outside of a housing assembly of the compressor.

Compressor having intermediate passage capable of conveying accumulated oil to a second compression part and air conditioner including same
