Refrigeration apparatus

A refrigeration apparatus, comprising:

• a refrigerant circuit in which refrigerant is circulated by a compressor to perform a refrigeration cycle, wherein, as refrigerant of the refrigerant circuit, refrigerant represented by Molecular Formula 1:
• C3HmFn, 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 refrigerant mixture containing the refrigerant is used;
• and
• predetermined functional resin components arranged so as to contact the refrigerant of the refrigerant circuit are made of any of polytetrafluoroethylene, polyphenylene sulfide, phenolic resin, polyamide resin, chloroprene rubber, silicone rubber, hydrogenated nitrile rubber, fluorine-containing rubber, and hydrin rubber.
