Claim:
1. A refrigerator, comprising: a plurality of compressors that compresses a refrigerant, wherein the plurality of compressors includes a first compressor and a second compressor, wherein the second compressor is disposed at a low pressure side, and wherein the first compressor compresses a refrigerant compressed at the second compressor; a condenser that condenses the refrigerant compressed in at least one of the plurality of compressors; a first expansion device that decompresses the refrigerant condensed in the condenser; a gas/liquid separator that separates the refrigerant decompressed in the first expansion device into liquid refrigerant and gaseous refrigerant; first and second evaporators, into which the liquid refrigerant separated in the gas/liquid separator is introduced; a flow adjuster disposed at an inlet-side of the first and second evaporators to introduce the liquid refrigerant separated in the gas/liquid separator into at least one evaporator of the first and second evaporators; a liquid refrigerant discharge disposed at a side of the gas/liquid separator to discharge the liquid refrigerant separated in the gas/liquid separator, the liquid refrigerant discharge configured to extend to the flow adjuster; a gaseous refrigerant discharge that discharges the gaseous refrigerant separated from the gas/liquid separator, and extends to an outlet-side of the first evaporator; and a second expansion device disposed at an inlet-side of the second evaporator to decompress the refrigerant, wherein an outlet side refrigerant pipe of the second evaporator extends to an inlet of the second compressor such that the refrigerant passed through the second evaporator is introduced into the second compressor, wherein an outlet side refrigerant pipe of the first evaporator is connected to an outlet side of a refrigerant pipe of the second compressor such that the refrigerant passed through the first evaporator joins the refrigerant compressed at the second compressor and is introduced into the first compressor, and wherein the refrigerant compressed at the first compressor is introduced into the condenser.
