Title:
COMPRESSOR AND AIR CONDITIONER HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2019/104983
Kind Code:
A1
Abstract:
A compressor and an air conditioner having the same, wherein the compressor comprises: a first compression part (10), a second compression part (20), an intermediate cavity (30) and an intermediate channel (40). Refrigerant discharged from the first compression part (10) enters the intermediate cavity (30); the intermediate channel (40) communicates with the intermediate cavity (30) and an inner cavity of the second compression part (20); a bottom port of the intermediate channel (40) is located at the bottom of the intermediate cavity (30); and air supplement refrigerant and/or the refrigerant discharged from the first compression part (10) are used to convey accumulated oil located in the intermediate cavity (30) to the inner cavity of the second compression part (20). When only the refrigerant discharged from the first compression part (10) is used to convey the accumulated oil located in the intermediate cavity (30) to the inner cavity of the second compression part (20), at least one part of the intermediate channel (40) is located outside of a casing assembly (90) of the compressor, thus improving the efficiency with which the accumulated oil in the intermediate cavity (30) is discharged from the intermediate cavity (30).
