A refrigerator comprising: a compressor compressing a refrigerant; a condenser condensing the refrigerant compressed in the compressor; a first evaporator for generating cool air to be supplied into one of a refrigerating compartment and a freezing compartment; a second evaporator for generating cool air to be supplied into the other of the refrigerating compartment and the freezing compartment; a flow adjustment part (130, 251, 253) configured to adjust a flow of the refrigerant so that the refrigerant is introduced into the first and second evaporators (150,160); a storage compartment temperature sensor including a refrigerating compartment temperature sensor disposed in the refrigerating compartment and configured to detect an inner temperature of the refrigerating compartment and a freezing compartment temperature sensor disposed in the freezing compartment configured to detect an inner temperature of the freezing compartment; a control unit configured to determine the simultaneous cooling operation of the refrigerating compartment and the freezing compartment or an exclusive operation of one storage compartment on the basis of target temperatures of the refrigerating compartment and the freezing compartment and a temperature detected by the storage compartment temperature sensor; and wherein the exclusive operation of the first and second evaporators (150, 160) is performed according to the temperature detected by the storage compartment temperature sensor, wherein the simultaneous operation of the first and second evaporators (150, 160) is performed according to the previously mapped information when the simultaneous cooling operation is performed, characterized in that the mapped information comprises a first information in relation to each of a first control state of the flow adjustment part (130, 251, 253) and a second control state of the flow adjustment part (130, 251, 253) when the simultaneous cooling operation starts, and a second information in relation to each of the first control state of the flow adjustment part (130, 251, 253) and the second control state of the flow adjustment part (130, 251, 253) when a refrigerant concentration occurs in any one of the first evaporator and the second evaporator (150, 160), the refrigerant concentration in any one of the first evaporator and the second evaporator (150, 160) occurring when a relatively large amount of refrigerant passes through said one of the first evaporator and the second evaporator (150, 160), and wherein the first information is different from the second information. a compressor compressing a refrigerant;
