Patent ID: 8691108

Claim:
A refrigeration apparatus, comprising: a refrigerant circuit in which refrigerant is circulated by a compressor to perform a refrigeration cycle, wherein the compressor includes a fluid machine for compressing refrigerant, and an electric motor for driving the fluid machine; the refrigerant circuit is filled with refrigerant represented by Molecular Formula 1: C 3 H m F n where “m” and “n” are integers equal to or greater than 1 and equal to or less than 5, and a relationship represented by an expression m+n=6 is satisfied, and having a single double bond in a molecular structure, or with refrigerant mixture containing the refrigerant; refrigerant oil having volume resistivity of equal to or greater than 10 10 Ω·m at 20° C. is used for the compressor; the refrigerant oil has surface tension of equal to or greater than 0.02 N/m and equal to or less than 0.04 N/m at 20° C.
