Abstract
A method of operating a refrigerator appliance includes operating a compressor within a sealed cooling system for a first portion of a period of time and deactivating the compressor for a second portion of the period of time. The method also includes measuring a temperature at an evaporator of the sealed system while operating the compressor for the first portion of the period of time. The method further includes determining an actual duty cycle of the compressor based on a ratio of the first portion of the period of time to the period of time. The method also includes determining an optimal duty cycle of the compressor based on the measured temperature at the evaporator and comparing the actual duty cycle of the compressor to the optimal duty cycle. Based on the comparison of the actual duty cycle to the optimal duty cycle, the speed of the compressor is adjusted.
