  • Patent number: 9146046
    Abstract: A refrigerator and a driving method thereof are disclosed. A primary compressor and a secondary compressor can form independent cycles together with corresponding evaporators so as to reduce unnecessary power consumption. Also, a backflow prevention valve is installed between the primary and secondary compressors to prevent an increase in pressure of the secondary compressor, or an auxiliary heat exchanger is installed at the outlet side of a second evaporator with high temperature to allow heat exchange of an outlet side pipe of a first evaporator with low temperature so as to shift a load of a freezing chamber into a relatively large refrigerating chamber, thereby improving efficiency of the refrigerator. In addition, an oil separator or an oil collection pipe is installed at the outlet sides of the compressors or an oil balancing pipe and an oil balancing valve are installed between the compressors, so as to uniformly maintain an oil amount between the compressors.
