The present invention enables an upper threshold value and a lower threshold value of the control temperature for controlling the temperature inside a refrigerator in accordance with the outdoor temperature to have nonlinearity. The upper threshold value of the control temperature is defined by a mathematical equation y_on = Ax^2 + Bx + C, and the lower threshold value is defined by the mathematical equation y_off = Dx^2 + Ex + F. Moreover, the present invention can more accurately control the target temperature inside the refrigerator to have the target temperature in accordance with the ambient temperature through nonlinear control. |
