Abstract
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.
