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 (11), a first evaporator (13) for providing cooling to the freezer compartment, a first compressor (15), a second compressor (17), a condensor (21), a second expansion valve (23), and a second evaporator (25) 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 (27) connects the second evaporator (25) to the first expansion valve (11) in a refrigerator flow relationship and the phase separator (27) provides intercooling between the first and second compressors.
