A refrigerator comprising: a compressor for compressing a refrigerant, and a condenser for 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 a 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, characterized in that the simultaneous operation of the first and second evaporators (150, 160) is performed according to a previously mapped time information when the simultaneous cooling operation is performed; wherein the mapped time information comprises: a first time 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/or a second time 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 a refrigerant concentration occurs in any one of the first evaporator and the second evaporator (150, 160). a compressor for compressing a refrigerant, and a condenser for condensing the refrigerant compressed in the compressor;
