<p>A refrigeration system suitable for use in a household refrigerator having a freezer compartment and a fresh food compartment is provided. The refrigeration system includes a first capillary tube (11,51), a first evaporator (13) for providing cooling to the freezer compartment, a two stage compressor (14), a condenser (21), a second capillary (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 capillary tube (11,51) in a refrigerator flow relationship and the phase separator (27) provides intercooling between the first and second stages (15,17) of the compressor (14). A first fraction of the second capillary tube (23) in a heat transfer relationship with the gaseous phase refrigerant providing intercooling and a second fraction of the second capillary tube (23) in a heat transfer relationship with the gaseous phase refrigerant supplied to the suction inlet of the first stage (15) of the compressor (14).</p> |
