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.
