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.

Abstract: A cool air discharge controller for a refrigerator and a controlling method thereof are provided.

Abstract: A refrigerator having a cool air path and a cool air discharge control blade for distributing cool air and controlling the discharge direction thereof and a method for controlling refrigerator temperature by controlling a cool air discharge direction are provided. By placing a disk-shaped cool air guiding portion in a discharge hole, cool air is rapidly and uniformly distributed via the cool air path and by low-speed rotation of the cool air discharge control blade, thus keeping the refrigerator at a predetermined temperature uniformly. Temperature sensors are installed on each side of the refrigeration compartment and the sensed average or representative temperatures are compared with a control reference temperature, so that cool air can be discharged to high temperature areas.
