ABSTRACT:
In a refrigerator temperature controlling apparatus and method thereof adopting GA-fuzzy inference, the refrigerator includes a cool air passage formed at both sides of the rear surface of a housing for guiding downward the cool air passing through a guide passage, a cool air discharging adjustment blade rotatably installed in front of the housing for dispersing and concentrating the cool air produced from discharging apertures, a driving motor for driving the cool air discharging adjustment blade, and a controller with each temperature sensors in left right side walls, for comparing the temperature inferred by the GA-fuzzy inference with data learned by reference to control the cool air discharging direction. Therefore, the cooling speed becomes fast and the temperature distribution depending on the refrigerated foodstuffs is made uniform throughout the refrigeration compartment. Also, the incoming external temperature due to door openings can be compensated for.
