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 in order to apply a refrigerant having a lower global warming coefficient (GWP) in view of the global warming prevention.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 12 having a spiral lap rising from an end plate and a revolving scroll 13 are engaged to form a compression chamber 15 in the bi-direction. A discharge hole 18 opening to a discharge chamber is provided at the central position of the end plate of the fixed scroll. A bypass hole 68 which allows the communication between the compression chamber and the discharge chamber before the compression chamber communicates with the discharge hole is provided in the end plate of the fixed scroll. A check valve 19 which allows a flow from the compression chamber side to the discharge chamber side in the bypass hole.
