COMPRESSOR AND REFRIGERATION CYCLE APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a compressor more suitable for using a working fluid including R1123.SOLUTION: A refrigerant including R1123(1,1,2- trifluoroethylene) is used as a working fluid. A polyvinyl ether oil is used as a lubrication oil for a compressor. A fixed scroll having a spiral lap rising from an end plate and a revolving scroll are engaged to form a compression chamber in the bi-direction. A suction volume of a first compression chamber formed in a lap outer wall side of the revolving scroll is larger than a suction volume of a second compression chamber formed in a lap inner wall side of the revolving scroll.
