    摘要： A refrigerator, a sealed refrigerant system, and method are provided where the refrigerator includes at least a refrigerated compartment and a sealed refrigerant system including an evaporator, a compressor, a condenser, a controller, an evaporator fan, and a condenser fan. The method includes monitoring a frequency of the compressor, and identifying a fault condition in the at least one component of the refrigerant sealed system in response to the compressor frequency. The method may further comprise calculating a compressor frequency rate based upon the rate of change of the compressor frequency, wherein a fault in the condenser fan is identified if the compressor frequency rate is positive and exceeds a condenser fan fault threshold rate, and wherein a fault in the evaporator fan is identified if the compressor frequency rate is negative and exceeds an evaporator fan fault threshold rate.

    摘要： 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.

    摘要： An appliance includes a cabinet; a first compartment; and a second compartment. The first compartment and the second compartment are separated by a vertical mullion. The cabinet also typically includes a coolant system that has: a single compressor for regulating a temperature of the first compartment and a temperature of the second compartment operably connected to at least one evaporator; a shared coolant fluid connection system; and a coolant fluid spaced within the shared coolant fluid connection system used to regulate both the temperature of the first compartment and the second compartment. The compressor can provide the shared coolant at at least two different pressures to at least one evaporator using the shared coolant fluid connection circuit. The ratio of the substantially steady state heat gain for the first compartment to the substantially steady state total heat gain for the overall cabinet is about 0.65:1 or greater.
