Zusammenfassung:PROBLEM TO BE SOLVED: To provide a cooling system favorably setting a storage to a desired temperature state while obtaining sufficiently high operating efficiency.SOLUTION: In the cooling system including a plurality of evaporators installed in parallel with expansion valves adiabatically expanding a refrigerant compressed by a compressor and condensed by a condenser, and evaporating the adiabatically expanded refrigerant, the storage of each show case is set to the desired temperature state by making the compressor suck the evaporated refrigerant to circulate the refrigerant. The cooling system includes a plurality of booster compressors installed downstream of a plurality of freezing evaporators of interest in parallel and lowering the evaporation temperature of the refrigerant in the freezing evaporators by sucking and compressing the refrigerant, a state determination part determining whether there exist one or more refrigerants discharged from the freezing evaporators and determined to be in a gas-liquid double phase state, and a booster control part increasing/decreasing at least one of the number of units in operation or the rotational frequency in operation of the plurality of booster compressors according to determination by the state determination part.
