PROBLEM TO BE SOLVED: To improve efficiency of a compressor for a low GWP refrigerant. SOLUTION: In the compressor, HFO-1234yf or a mixed refrigerant containing HFO-1234yf as one component is used, sliding members of an aluminum-silicon-based alloy are used, and the sliding members are subjected to barrel polishing. Not only reduction of the global warming potential (GWP), by prevention of internal leakage due to low differential pressure and low friction sliding due to low viscous lubrication oil and a surface modifying layer, a sliding loss of the compressor 1 is inhibited, electric power consumption is reduced and the efficiency is improved so that the environmental burden can be reduced.
