To realize varying of temperature set values of a plurality of heated storages in a cold-warm storage device with a simple configuration at low cost.
When radiating heat of a refrigerant at a temperature exceeding a critical point, the heat of the refrigerant is radiated in a state that the refrigerant has different temperature ranges. Thereby, a refrigerant temperature in a heat radiator 30 close to a compressor 40 becomes highest, and the refrigerant temperature in a heat radiator 36 close to an expansion valve 42 becomes lowest. Accordingly, the passing refrigerant temperature becomes lower in order of the heat radiator 30, a heat radiator 32, a heat radiator 34, and the heat radiator 36. Accordingly, the temperature set values of the storages adjacent with the respective heat radiators are different.
