PURPOSE: An operation system of a refrigerator with an inverter compressor and a method thereof are provided to save power used for the inverter compressor by lower the temperature of first and second storage units. CONSTITUTION: An operation system of a refrigerator comprises a first storage unit(110), a second storage unit(120), an inverter compressor(130), a condenser(140), a valve(140), and a control unit(160). The first storage unit comprises a first temperature sensor and a first evaporator. The second storage unit comprises a second temperature sensor and a second evaporator. The inverter compressor compresses coolant into a gas state of high pressure. The condenser cools the coolant compressed in the inverter compressor into a liquid state. The valve is opened and closed so that the coolant cooled in the condenser is supplied to the first storage unit or the second storage unit. The control unit controls the opening/closing of the valve. The sizes of the first and second storage units are saved in the control unit. Temperature measurement data is transmitted from the first and second temperature sensors to the control unit. When the temperature measurement data is a maximum value, the inverter compressor is drives at RPM higher than the normal RPM.
