The present invention provides a method for controlling refrigerator temperature by controlling a cool air discharge direction, comprising the steps of (a) determining whether a refrigerant circulating compressor (11a) is initially turned on when power is applied; (b1) determining whether said compressor (11a) is on in a normal operation, when said compressor (11a) is not initially on; and (b2) determining whether a damper (19) for controlling the amount of cool air discharged into a refrigerator is open, when said compressor (11a) is on in the normal operation; (c) firstly discharging cool air to be distributed by rotating a cool air discharge control blade (26), when said compressor (11a) is initially on; (d) determining whether a control reference temperature for non-discharge of cool air is larger than the absolute value of a difference in temperatures sensed by said two temperature sensing means(52, 53), when said compressor (11a) is not on in the normal operation or when said damper (19) is not open; (e) determining whether a control reference temperature for discharge of cool air is larger than the absolute value of a difference in temperatures sensed by two temperature sensing means (52, 53)which are selected from at least two temperature sensing means (52, 53) arranged to face each other a predetermined difference apart, when said damper (19) is open; (f1) secondly rotating a cool air discharge control blade (26), when said control reference temperature for discharge of cool air is not larger than the absolute value of a difference in temperatures sensed by said two temperature sensing means (52, 53); and (f2) thirdly rotating a cool air discharge control blade (26), when said control reference temperature for non-discharge of cool air is not larger than the absolute value of a difference in temperatures sensed by said two temperature sensing means (52, 53); and (g) discharging the cool air in a predetermined direction, when said control reference temperature for discharge of cool air is larger than the absolute value of a difference in temperatures sensed by said two temperature sensing means (52, 53) or when said control reference temperature for non-discharge of cool air is larger than the absolute value of a difference in temperatures sent by said two temperature sensing means (52, 53).
