Abstract
A control system for operating a refrigerator appliance is provided. The refrigerator has a variable damper, a variable speed fan, and a variable speed compressor. The damper position, evaporator fan speed, and compressor speed are determined through interacting feedback control loops based on the set point temperatures for the fresh food and freezer compartments as well as the measured temperatures in such compartments. The adjustment of these actuators can eliminate large temperature fluctuations and discontinuities in the air flow and improve the thermal performance and energy efficiency of the refrigerator.
