A method of controlling a refrigerator, the refrigerator comprising a main body partitioned into a refrigerating chamber and a freezing chamber, a refrigerating chamber evaporator disposed in the refrigerating chamber, a freezing chamber evaporator disposed in the freezing chamber, and a compressor for supplying refrigerant to the refrigerating chamber evaporator and the freezing chamber evaporator; wherein a target temperature region of the refrigerating chamber is set having a first upper limit temperature and a first lower limit temperature and a refrigerating chamber priority cooling temperature is set to be higher than the refrigerating chamber target temperature region; wherein a target temperature region of the freezing chamber is set having a second upper limit temperature and a second lower limit temperature and a freezing chamber priority cooling temperature is set to be higher than the freezing chamber target temperature region; and the method of controlling the refrigerator comprising the steps of: when a temperature of the refrigerating chamber does not meet the refrigerating chamber target temperature region and a temperature of the freezing chamber does not meet the freezing chamber target temperature region, primarily cooling the refrigerating chamber such that the temperature of the refrigerating chamber is at least lower than the refrigerating chamber priority cooling temperature; further characterized by the steps: when the temperature of the refrigerating chamber is lower than the refrigerating chamber priority cooling temperature, stopping the cooling of the refrigerating chamber and cooling the freezing chamber below the freezing chamber priority cooling temperature, wherein when the temperature of the freezing chamber is lower than the freezing chamber priority cooling temperature, the cooling of the freezing chamber is stopped and the refrigerating chamber is cooled up to the refrigerating chamber target temperature region. when a temperature of the refrigerating chamber does not meet the refrigerating chamber target temperature region and a temperature of the freezing chamber does not meet the freezing chamber target temperature region, primarily cooling the refrigerating chamber such that the temperature of the refrigerating chamber is at least lower than the refrigerating chamber priority cooling temperature; further characterized by the steps: when the temperature of the refrigerating chamber is lower than the refrigerating chamber priority cooling temperature, stopping the cooling of the refrigerating chamber and cooling the freezing chamber below the freezing chamber priority cooling temperature, wherein when the temperature of the freezing chamber is lower than the freezing chamber priority cooling temperature, the cooling of the freezing chamber is stopped and the refrigerating chamber is cooled up to the refrigerating chamber target temperature region. when the temperature of the refrigerating chamber is lower than the refrigerating chamber priority cooling temperature, stopping the cooling of the refrigerating chamber and cooling the freezing chamber below the freezing chamber priority cooling temperature, wherein when the temperature of the freezing chamber is lower than the freezing chamber priority cooling temperature, the cooling of the freezing chamber is stopped and the refrigerating chamber is cooled up to the refrigerating chamber target temperature region.
