Abstract
A refrigerating appliance includes a refrigerant line having a compressor and a condenser. A thermal exchange media is delivered from the condenser and through the refrigerant line to at least a freezer evaporator of a plurality of evaporators, wherein the thermal exchange media leaving the freezer evaporator defines spent media that is returned to the compressor. A multi-directional outlet valve selectively delivers the thermal exchange media to the freezer evaporator, wherein the multi-directional outlet valve also selectively delivers the thermal exchange media to at least one secondary evaporator of the plurality of evaporators to define a partially-spent media that is delivered to the freezer evaporator.
