A refrigerator control method of the present embodiment comprises the steps of: operating a compressor by operating a first cooling cycle for cooling a first storage chamber, and operating a first cold air supply means for the first storage chamber; and operating the compressor by switching into a second cooling cycle for cooling a second storage chamber, and operating a second cold air supply means, when a stop condition of the first cooling cycle is satisfied, wherein the cooling capacity of the compressor in the current second cooling cycle is determined on the basis of the representative temperature of the second storage chamber during one operating cycle which includes the previous first cooling cycle and the previous second cooling cycle, and a control unit performs control such that the compressor is operated in the current second cooling cycle with the determined cooling capacity.

A cooling system partially floods the low temperature low side heat exchangers (e.g., freezers) in the system. An accumulator is positioned between the low temperature low side heat exchangers and the low temperature compressor. The accumulator collects the refrigerant (both liquid and vapor) from the flooded low temperature low side heat exchangers. Refrigerant discharged by the low temperature compressor is fed through the accumulator so that heat can be transferred to the refrigerant collected in the accumulator. As a result, the temperature of the refrigerant discharged by the low temperature compressor drops before that refrigerant reaches the medium temperature compressor.

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.
