In a refrigeration apparatus (1) for which refrigerant containing a compound represented by a molecular formula of C3HmFn(note that m=1-5, n=1-5, and m+n=6) is used, a compressor including a first compression mechanism (20A) and a second compression mechanism (20B) inside a casing (11) is used in order to reduce or prevent decomposition of refrigerant due to an increase in discharge temperature of a compressor (10) performing a compression phase of refrigerant in a refrigeration cycle.
