Abstract
A refrigerator system suitable for use in a household refrigerator having a freezer compartment and a fresh food compartment is provided. The refrigerator system includes a first expansion valve, a first evaporator for providing cooling to the freezer compartment, a first compressor, a second compressor, a condensor, a second expansion valve, and a second evaporator providing cooling to the fresh food compartment. All the above elements are connected together in series in that order, in a refrigerant flow relationship. A phase separator connects the second evaporator to the first expansion in a refrigerator flow relationship and the phase separator provides intercooling between the first and second compressors.
