ABSTRACT:
A temperature controlling method and apparatus for a refrigerator are provided, in which a temperature-equilibrating position into which cool air is to be discharged is calculated based on a fuzzy model and learning of a neural network, using the change in temperatures measured by only a small number of temperature sensors at a predetermined number of portions within a refrigeration compartment, and then the rotation velocity of a ventilation fan and a stop angle of a rotary blade are controlled according to the calculated temperature-equilibrating position. As a result, the cool air is appropriately discharged into each portion according to the distance between the rotary blade and a target position, so that the optimal temperature equilibrium is obtained in the refrigeration compartment.
