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. 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. Plural accumulators(123,125) are connected between the four evaporators and the common refrigerant supply passage, wherein one accumulator is connected with rear ends of the first and second evaporators equal in control temperature zone, and the other accumulator is connected with rear ends of the third and fourth evaporators equal in control temperature zone. Plural check valves are connected between the accumulators and the common refrigerant supply passage in the connection state of the accumulators.
