Abstract: Methods of operation for refrigerator appliance configurations with a controller, a condenser, at least one evaporator, a compressor, and two refrigeration compartments. The configuration may be equipped with a variable-speed or variable-capacity compressor, variable speed evaporator or compartment fans, a damper, and/or a dual-temperature evaporator with a valve system to control flow of refrigerant through one or more pressure reduction devices. The methods may include synchronizing alternating cycles of cooling each compartment to a temperature approximately equal to the compartment set point temperature by operation of the compressor, fans, damper and/or valve system. The methods may also include controlling the cooling rate in one or both compartments. Refrigeration compartment cooling may begin at an interval before or after when the freezer compartment reaches its lower threshold temperature. Freezer compartment cooling may begin at an interval before or after when the freezer compartment reaches its upper threshold temperature.

Abstract: A method of determining a time delay for turning off an evaporator fan in a refrigerator after a compressor of the refrigerator is turned off includes operating the evaporator fan in the refrigerator for a period of time, operating the compressor of the refrigerator to cool the refrigerator to a predetermined temperature after turning off the evaporator fan, determining a power consumption value for operating the compressor to cool the refrigerator, repeating the previous steps to obtain a plurality of times and a plurality of power consumption values, selecting the time coinciding with a lowest power consumption value, and adapting the refrigerator to use the time as the time delay for turning off the evaporator fan in the refrigerator after the compressor of the refrigerator is turned off.
