PROBLEM TO BE SOLVED: To provide a replacing method for a refrigerating cycle capable of extending a service life after replacement by carrying out replacement with a compressor sealing linear alkylbenzene with little deterioration of viscosity even in a high temperature. SOLUTION: By replacing a rolling piston type compressor 102a storing hard alkylbenzene of the refrigerating cycle with the rolling piston type compressor 102b sealing the linear alkylbenzene 107, the service life after replacement can be extended since the linear alkylbenzene 107 has higher viscosity in high temperature and high pressure than the hard alkylbenzene 101 in the rolling piston type compressors 102a and 102b wherein a container interior becomes a high temperature and a high pressure.
