Refrigerator with energy consumption optimization using adaptive fan delay

摘要

A method of determining a time delay for turning off an evaporator fan in a refrigerator after a compressor of the refrigerator is turned off includes operating the evaporator fan in the refrigerator for a period of time, operating the compressor of the refrigerator to cool the refrigerator to a predetermined temperature after turning off the evaporator fan, determining a power consumption value for operating the compressor to cool the refrigerator, repeating the previous steps to obtain a plurality of times and a plurality of power consumption values, selecting the time coinciding with a lowest power consumption value, and adapting the refrigerator to use the time as the time delay for turning off the evaporator fan in the refrigerator after the compressor of the refrigerator is turned off.

1. A method of determining a time delay for turning off an evaporator fan in a refrigerator after a compressor of the refrigerator is turned off, the method comprising:
(a) operating the evaporator fan in the refrigerator for a period of time; (b) operating the compressor of the refrigerator to cool the refrigerator to a predetermined temperature after turning off the evaporator fan; (c) determining a power consumption value, the power consumption value including power consumed by operating the compressor to cool the refrigerator; (d) repeating steps (a)-(c) to obtain a plurality of times and a plurality of power consumption values; (e) selecting the time coinciding with a lowest power consumption value; and (f) adapting the refrigerator to use the time as the time delay for turning off the evaporator fan in the refrigerator after the compressor of the refrigerator is turned off.
