ABSTRACT:
An apparatus and method for controlling the temperature in a refrigerating chamber of a refrigerator by supplying appropriate cooled air to each of the compartments of the refrigerating chamber according to a temperature in each of the compartments. A cooled air controlling plate is provided for controlling the size of the cooled air discharge outlet according to the individual temperatures in the compartments. The cooled air controlling plate is moved in an up and down direction in multiple stages depending on the temperature in the refrigerating chamber to control the cooled air discharge rate to each of the compartments of the refrigerating chamber so as to make the temperature in the refrigerating chamber uniform.
