Refrigerator having a cold air supply means and control method therefore

A method for controlling a refrigerator, the method comprising:

• sensing a temperature of a storage room;
• operating a cool air supply means at a first cooling power in response to the sensed temperature of the storage room is being equal to or above a first reference temperature;
• operating the cool air supply means at a second cooling power, which is less than the first cooling power, in response to the sensed temperature of the storage room being equal to or below a second reference temperature, which is less than the first reference temperature, while the cool air supply means is operating at the first cooling power;
• and
• operating the cool air supply means at an adjusted first cooling power or adjusted second cooling power according to the temperature of the storage room,
• wherein, in response to the temperature of the storage room being equal to or above the first reference temperature while the cool air supply means operates at the adjusted first cooling power, the cool air supply means operates at an increased first cooling power greater than the adjusted first cooling power.

• wherein, in response to the temperature of the storage room reaching to a predetermined temperature that is greater than the second reference temperature while the cool air supply means operates at the reduced second cooling power, the adjusted first cooling power of the cool air supply means is determined as (a sum of the first cooling power and the second cooling power, which are determined previously)×α, and the cool air supply means operates at the adjusted first cooling power, and
• wherein α is greater 0 and less than 1.
