Dual evaporator refrigeration system using zeotropic refrigerant mixture

A dual evaporator refrigerator appliance comprising:

• a compressor;
• a condenser configured to receive a refrigerant stream from the compressor, and comprising a first portion and a second portion, and wherein the refrigerant stream received from the compressor comprises a zeotropic refrigerant mixture;
• a freezer evaporator;
• a fresh food evaporator;
• and
• a separating component connected between the first and second portions of the condenser to receive a refrigerant stream from the first portion of the condenser, and configured to separate the refrigerant stream received thereby into a fresh food refrigerant stream which flows to the fresh food evaporator and a freezer refrigerant stream, which flows through the second portion of the condenser to the freezer evaporator,
• whereby the freezer evaporator and the fresh food evaporator substantially simultaneously receive the freezer refrigerant stream and the fresh food refrigerant stream, respectively.
