    Abstract: PROBLEM TO BE SOLVED: To obtain a composition for a refrigerator-working fluid capable of suppressing the thermal decomposition of an ester base oil and a method for working the refrigerator by using the composition. SOLUTION: This composition for a refrigerator-working fluid by which thermal decomposition of an ester base oil is suppressed contains a refrigerator oil obtained by mixing an ester base oil with an aromatic ring compound and/or a heterocyclic compound and a hydrofluorocarbon containing difluoromethane (HFC32). The objective method for operating a refrigerator is performed by using the composition for the refrigerator-working fluid while suppressing thermal decomposition of the ester base oil.
