In a hermetic compressor using a hydrocarbon refrigerant and mineral lubrication oil, if the viscosity of the mineral lubrication oil is lowered for higher efficiency, lubrication performance is degraded, and reliability lowers. Therefore, additives are added to the refrigerating machine oil to improve lubrication performance and to meet the needs for higher efficiency, lower noise and higher reliability. <IMAGE> |
