Disclosed is a refrigerator. The refrigerator includes a first compressor (100) configured to compress refrigerant, a first condenser (1 10) configured to condense the refrigerant compressed in the first compressor (100), a first expansion valve (120) configured to reduce a temperature and pressure of the refrigerant condensed in the first condenser (1 10), a first evaporator (140) configured to evaporate the refrigerant having passed through the first expansion valve (120), a second compressor (200) configured to compress refrigerant, a second condenser (210) configured to condense the refrigerant compressed in the second compressor (200), a second expansion valve (220) configured to reduce a temperature and pressure of the refrigerant condensed in the second condenser (210) and a second evaporator (230) configured to evaporate the refrigerant having passed through the second expansion valve (220). The refrigerator further includes a heat exchanger (130) located at a rear of the first expansion valve (120), and the heat exchanger (130) and the second condenser (210) undergo heat exchange therebetween. |
