ABSTRACT:
A method for reducing operating noise of a refrigerator comprises of steps of detecting an exterior temperature of the refrigerator, comparing the detected the exterior temperature with a reference temperature, if the detected exterior temperature is less than or equal to the reference temperature, periodically detecting exterior light levels, determining whether or not an absolute value of the difference between two successive exterior light levels is more than or equal to a reference light level for measuring a variation of the exterior light levels with time, if the absolute value is more than or equal to the first reference light level, deciding whether or not the former is more than the latter, wherein, if the former is less than or equal to the latter, operating the refrigerator in a normal operation mode, and if the former is more than the latter, increasing by a predetermined temperature a first driving reference temperature for driving a first fan for a refrigerator compartment and a second driving reference temperature for driving a compressor and a second fan for a freezer compartment, respectively, and operating the refrigerator at a reduced noise level.
