refrigerator 1 comprises: a refrigeratorcompartment temperature detector 32, a freezercompartment temperature detector 34, and an auxiliarystorage temperature detector 36 to detect temperatures in the refrigerator compartment 7, thefreezer compartment 5, and theauxiliary storage 9, respectively; acompressor driver 40 to drive acompressor 38; a refrigeratorcompartment fan driver 42 and a freezercompartment fan driver 44, which drive therefrigeration compartment fan 16 and thefreezer compartment fan 12, respectively; a refrigeratorcompartment damper driver 46 and anauxiliary damper driver 48 to drive therefrigerator compartment damper 18 and theauxiliary damper 26, respectively; acontroller 50 controlling thecompressor driver 40, the refrigeratorcompartment fan driver 42, the freezercompartment fan driver 44, the refrigeratorcompartment damper driver 46, and theauxiliary damper driver 48 based on results detected by thetemperature detectors - The
controller 50 determines whether each compartment requires a cooling operation according to the temperatures of the respective compartments detected by the refrigeratorcompartment temperature detector 32, the freezercompartment temperature detector 34, and the auxiliarystorage temperature detector 36. - The

controller 50 compares a refrigerator compartment temperature detected by the refrigeratorcompartment temperature detector 32 and a refrigerator compartment pre-set temperature. If the detected refrigerator compartment temperature is higher than the refrigerator compartment pre-set temperature, thecontroller 50 controls thecompressor driver 40 and the refrigeratorcompartment fan driver 42 to drive thecompressor 38 and therefrigerator compartment fan 16, respectively. Also, thecontroller 50 controls the refrigeratorcompartment damper driver 46 andauxiliary damper driver 48 to open therefrigerator compartment damper 18 and to close theauxiliary damper 26, respectively, so that the temperature of the refrigerator compartment 7 reaches the pre-set temperature. - If the temperature of the refrigerator compartment 7 is determined to be the pre-set temperature and the detected auxiliary storage temperature is higher than the auxiliary storage pre-set temperature, the
controller 50 controls the refrigeratorcompartment damper driver 46 and theauxiliary damper driver 48 to close therefrigerator compartment damper 18 and to open theauxiliary damper 26, respectively. - Accordingly, the cooling air, which is generated in the refrigerator compartment evaporator, is supplied to the
auxiliary storage 9 through theauxiliary supply duct 20, and the cooling air within theauxiliary storage 9 returns to the refrigerator compartment evaporator through the auxiliary returningduct 24. Accordingly, theauxiliary storage 9 can be cooled by the cooling air generated in the refrigerator compartment evaporator. - Also, if the auxiliary storage temperature detected by the auxiliary
storage temperature detector 36 is determined to be the auxiliary storage pre-set temperature, thecontroller 50 controls the refrigeratorcompartment fan driver 42 to stop the driving of therefrigerator compartment fan 16, and controls the refrigeratorcompartment damper driver 46 and theauxiliary damper driver 48 to close therefrigerator compartment damper 18 and theauxiliary damper 26, respectively, so that the cooling air is not supplied to theauxiliary storage 9. - Also, after the auxiliary storage temperature is satisfied, the
controller 50 determines whether the freezer compartment temperature detected by the freezercompartment temperature detector 34 reaches the pre-set temperature. If the freezer compartment temperature is satisfied, thecontroller 50 controls thecompressor driver 40 and the freezercompartment fan driver 44 to stop the driving of thecompressor 38 and thefreezer compartment fan 12 so that the cooling operation is terminated. - After the termination of the cooling operation, a frost removal cycle is implemented during a predetermined period of time. The frost removal cycle is implemented by driving the
refrigerator compartment fan 16 during a predetermined period of the time after thecompressor 38 stops driving, and opening therefrigerator compartment damper 18, and closing theauxiliary damper 26. With the frost removal cycle, residual cooling air in the refrigerator compartment evaporator, which remains after thecompressor 38 stop the driving flows into the refrigerator compartment 7, improves cooling efficiency. Also, frost is removed to some degree without using a frost removal heater (not shown). -

storage temperature detector 36 is determined to be the auxiliary storage pre-set temperature, thecontroller 50 controls theauxiliary damper driver 48 to close theauxiliary damper 66, so that the supply of the cooling air from theauxiliary storage 9 is stopped. - Herein, a temperature control of the
auxiliary storage 9 is implemented with the cooling air generated in the freezer compartment evaporator. A temperature of theauxiliary storage 9 reaches an appropriate temperature first because an inner volume of theauxiliary storage 9 is smaller than that of thefreezer compartment 5. - After completion of the cooling operation, the frost removal cycle is implemented.
