PURPOSE: A refrigerating cycle having a plurality of evaporators is provided to independently control a temperature in four separated spaces where four evaporators are installed, and prevent a cooling speed from lowering due to shortage of a refrigerant by preventing a back current of the refrigerant due to a difference in evaporation pressure, thereby appropriately coping with a load by minimizing inequality of a refrigerating cycle. CONSTITUTION: A compressor(110) and a condenser(113) are installed. Four evaporators(119,120,121,122) are installed at separated spaces for receiving a refrigerant from the condenser for evaporating the refrigerant. A common refrigerant supply passage(L11) is formed to mix refrigerants passing through the four evaporators to be moved into the compressor. An accumulator is installed between the four evaporators and the common refrigerant supply passage for common use. Plural check valves are installed at a discharge port of each evaporator to supply the refrigerant passing through the evaporators without a back current.
