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. Temperature sensors are installed on each side of the refrigeration compartment and the sensed averages or representative temperatures are compared with control reference temperatures, so that cool air can be discharged to high temperature areas by controlling the cool air discharge direction such that the cool air discharge control blade is rotated to provide cool air flow depending on a sensed temperature difference.
