Abstract (en)

A method of controlling a refrigerator (1) including:a cabinet (10) in which a refrigerating compartment (13) and a freezing compartment (12) are formed;a refrigerating compartment temperature sensor (32) included in the refrigerating compartment (13);an evaporator (17) included in the freezing compartment (12);a freezing compartment fan (19) included in the freezing compartment (12) and configured to supply cold air to the freezing compartment (12) and the refrigerating compartment (13);a compressor (15) operable with variable cooling power;a condenser (16) connected to the compressor (15);a condenser fan (18) configured to cool the condenser (16); anda controller (30) configured to control the compressor (15), the freezing compartment fan (19), and the condenser fan (18) to maintain the refrigerating compartment (13) at a target control temperature depending on temperature detected by the refrigerating compartment temperature sensor (32), the method comprising:detecting (S 120) outside temperature through an outside temperature sensor (31) configured to detect ambient temperature of the refrigerator (1);performing a winter operation (200) when the outside temperature detected by the outside temperature sensor (31) is equal to or less than a set temperature; andperforming a normal operation (300) when the temperature detected by the outside temperature sensor (31) is higher than the set temperature.
