<p><P>PROBLEM TO BE SOLVED: To provide a refrigerating device preventing decomposition of a refrigerant and using the refrigerant comprising a compound indicated by a molecular formula of C<SB>3</SB>H<SB>m</SB>F<SB>n</SB>by solving a problem wherein when a general single-stage one-cylinder type compressor is used, if the cylinder capacity or a compression ratio is increased, increase in excessive compression of a refrigerant causes increase in discharge flow speed, leading to easy rise in the temperature of the refrigerant. <P>SOLUTION: In the refrigerating device using the refrigerant comprising the compound indicated by the molecular formula of C<SB>3</SB>H<SB>m</SB>F<SB>n</SB>(wherein, m=1-5, n=1-5 and m+n=6), a compressor 10 having a first compression mechanism 20A and a second compression mechanism 20B within a casing 11 is used for a compressor 10 for performing a compression stroke of the refrigerant in a refrigerating cycle. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
