Provided are a cooling system and a control method thereof. The cooling system includes a first compressor compressing a refrigerant to cool a set space, a second compressor disposed on an outlet-side of the first compressor, an outdoor heat exchanger in which the refrigerant compressed in the first or second compressor is heat-exchanged with external air, an expansion device decompressing the refrigerant condensed in the outdoor heat exchanger, a cooling evaporator evaporating the refrigerant decompressed in the expansion device to supply cool air into the set space, a bypass tube allowing the refrigerant compressed in the first compressor to bypass the second compressor, and a valve device controlling the refrigerant discharged from the first compressor to allow the refrigerant to be selectively introduced into the second compressor.
