ABSTRACT:
A temperature control apparatus for a refrigerator and a control method therefor, mount an air circulation fan in addition to a prior refrigerating fan into the refrigerating compartment, drive the air circulation fan together with the refrigerating fan or drive only the air circulation fan, obtain a uniform cooling effect of a refrigerating compartment, feebly circulate a cool air when opening a door of the refrigerating compartment, and quickly cool the refrigerating compartment after closing the door. The temperature control apparatus of the refrigerator includes: an air circulation fan which is additionally mounted to the refrigerating compartment, and is separated from the refrigerating fan; and a controller which drives the compressor, the refrigerating fan, and the air circulation fan if a refrigerating compartment temperature sensed by the refrigerating compartment temperature sensor is higher than a refrigerating compartment set temperature, and periodically turns on or off the air circulation fan under an off state of the refrigerating fan if the refrigerating compartment door is opened.
