Abstract
According to a method of controlling a refrigerator in accordance with the present invention, after the refrigerating chamber and the freezing chamber are operated at the same time, refrigerant recovery is performed and the refrigerating chamber is then cooled. Accordingly, imbalance due to the pressure difference between the refrigerating chamber evaporator and the freezing chamber evaporator can be solved. Further, there is an advantage in that the refrigerating chamber can be cooled rapidly since refrigerant is supplied to the refrigerating chamber smoothly.
