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 , a compressor for supplying refrigerant to the refrigerating chamber evaporator and the freezing chamber evaporator ; and a 3-way valve for controlling the refrigerant introduced from the compressor to the freezing chamber evaporator and the refrigerating chamber evaporator ; the method comprises the steps of: checking temperatures of the refrigerating chamber and the freezing chamber ; and operating (S15) the refrigerating chamber and the freezing chamber at the same time; after the simultaneous operation of the refrigerating chamber and the freezing chamber , cooling (S25) the refrigerating chamber ; after the cooling of the refrigerating chamber , cooling (S35) the freezing chamber ; and after the cooling of the freezing chamber , recovering (S45) the refrigerant from at least one of the refrigerating chamber evaporator and the freezing chamber evaporator , wherein recovering the refrigerant includes stopping a condenser fan for ventilating an air into a condenser and driving a freezing chamber fan in a state where the condenser fan is being stopped. 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 , a compressor for supplying refrigerant to the refrigerating chamber evaporator and the freezing chamber evaporator ; and a 3-way valve for controlling the refrigerant introduced from the compressor to the freezing chamber evaporator and the refrigerating chamber evaporator ; the method comprises the steps of: checking temperatures of the refrigerating chamber and the freezing chamber ; and operating (S15) the refrigerating chamber and the freezing chamber at the same time; after the simultaneous operation of the refrigerating chamber and the freezing chamber , cooling (S25) the refrigerating chamber ; after the cooling of the refrigerating chamber , cooling (S35) the freezing chamber ; and after the cooling of the freezing chamber , recovering (S45) the refrigerant from at least one of the refrigerating chamber evaporator and the freezing chamber evaporator , wherein recovering the refrigerant includes stopping a condenser fan for ventilating an air into a condenser and driving a freezing chamber fan in a state where the condenser fan is being stopped. checking temperatures of the refrigerating chamber and the freezing chamber ; and operating (S15) the refrigerating chamber and the freezing chamber at the same time; after the simultaneous operation of the refrigerating chamber and the freezing chamber , cooling (S25) the refrigerating chamber ; after the cooling of the refrigerating chamber , cooling (S35) the freezing chamber ; and after the cooling of the freezing chamber , recovering (S45) the refrigerant from at least one of the refrigerating chamber evaporator and the freezing chamber evaporator , wherein recovering the refrigerant includes stopping a condenser fan for ventilating an air into a condenser and driving a freezing chamber fan in a state where the condenser fan is being stopped. <EOS>
