<P>PROBLEM TO BE SOLVED: To attain stable operation from a low temperature area to a high temperature area. Ž<P>SOLUTION: A refrigerating cycle device 10 circulates a mixed refrigerant in which a plurality of component refrigerants are mixed. An expansion valve 40 is equipped with a power element 42. An enclosed refrigerant enclosed in the power element 42 includes one component refrigerant of the plurality of component refrigerants. Inclination of a saturated vapor pressure curve SV1 of the component refrigerant is larger than that of a saturated vapor pressure curve SV0 of the mixed refrigerant. As a result, the enclosed refrigerant also shows inclination larger than that of the mixed refrigerant. This characteristic can avoid an excessive opening of the expansion valve in the low-temperature area and can provide a suitable opening for load in the high temperature area, which can provide the stable operation from the low temperature area to the high temperature area.
