<P>PROBLEM TO BE SOLVED: To prevent deterioration of resin functional components in a compressor of a refrigerating device using a refrigerant indicated by a molecular formula of C<SB>3</SB>H<SB>m</SB>F<SB>n</SB>(wherein, m and n are ≥1 and ≤5 of integer numbers and a relationship of m+n=6 is achieved) and having one double bond in the molecular structure or a refrigerant mixture including the refrigerant. <P>SOLUTION: In the compressor (30), each bearing (41, 42, 43, 44) and an insulation material of an electric motor (85) are constituted as the resin functional components coming into contact with the refrigerant and refrigerating machine oil. In the refrigerating machine oil, an aniline point is ≥-100°C and ≤0°C. <P>COPYRIGHT: (C)2011,JPO&INPIT |
