Abstract

A system and method for controlling automatic defrost of a refrigerator device adaptively moves the defrost cycle to a time period of comparatively low compressor activity based on an evaluation of compressor usage over a cyclically recurring time interval. An adaptive defrost controller (ADC) analyzes stored data to develop a profile for compressor activity vs. time. From this profile, high compressor activity times of the time interval are distinguished from low compressor activity times in the time interval and a defrost cycle is scheduled based on the results of the analyzed data.
