(57) Abstract :
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.
