| 摘要 |
The present invention relates to a refrigerator having enhanced operation efficiency, comprising: a first compressor compressing a refrigerant; a first condenser condensing the refrigerant compressed in the first compressor; a first expansion valve lowering the temperature and pressure of the refrigerant condensed in the first condenser; a first evaporator vaporizing the refrigerant which has passed through the first expansion valve; a second compressor compressing a refrigerant; a second condenser condensing the refrigerant compressed in the second compressor; a second expansion valve lowering the temperature and pressure of the refrigerant condensed in the second condenser; and a second evaporator vaporizing the refrigerant which has passed through the second expansion valve, wherein a first heat exchanger is disposed at a rear end of the first expansion valve, a second heat exchanger is disposed at a rear end of the second expansion valve, and the first heat exchanger and the second heat exchanger are heat-exchanged. |
