PROBLEM TO BE SOLVED: To solve problems of a refrigerating cycle system using a non-azeotropic mixture refrigerant wherein two refrigerant storage vessels are required for converting refrigerant compositions, which enlarges the device and increases the cost, and a refrigerant rectifier may not be stably operated by changes in outside air temperatures. SOLUTION: The refrigerating cycle system is provided with a refrigerating cycle, the refrigerant rectifier, a first cooling device cooling low boiling point refrigerant components separated in the refrigerant rectifier and a refrigerant storage device storing the refrigerant flowing from the first cooling device. This system is also provided with a first opening/closing valve in a pipe connecting the lower part of the refrigerant rectifier to a compressor delivery side of the refrigerating cycle, a second opening/closing valve connecting the outlet side of the first cooling device and the outlet side of a use side heat exchanger of the refrigerating cycle and a third opening/closing valve in a pipe connecting the lower part of the refrigerant rectifier to a low pressure side of the refrigerating cycle. The ratio of the low boiling point refrigerant components to high boiling point components of the non-azeotropic mixture refrigerant in the refrigerating cycle is made variable.
