Abstract
A dual compartment single evaporator refrigerator and temperature control apparatus that effectively controls two compartment temperatures by making the evaporator fan control independent of the compressor cycle. The compressor cycle is initiated by the fresh food compartment temperature, runs for a predetermined minimum time, and is terminated by the freezer temperature. The evaporator fan runs with the compressor and is terminated by the freezer control temperature. A small portion of the evaporator air circulation flows through the fresh food compartment and compartment temperatures are balanced according to the freezer temperature settings during the post-compressor cycle fan control. The temperature control set points to operate the compressor and fan are based on algorithms that compensate the control for the combination of freezer and fresh food temperature settings.
