1. A refrigerator comprising:
a storage chamber configured to be maintained at a temperature above zero degrees Celsius, and comprising an isolated room and a main room, wherein the isolated room is configured to be maintained at a lower temperature than the main room;
an evaporator disposed in a duct that is fluidly connected to the storage chamber;
a panel configured to separate the storage chamber and the duct, and comprising a first outlet for discharging air into the main room and an auxiliary outlet for discharging air into the isolated room;
a compressor;
a valve disposed in a flow path which connects the compressor to the evaporator;
a first fan configured to drive air that is cooled by the evaporator to the storage chamber; and
a controller configured to:
control at least one of the compressor or the valve to supply a refrigerant to the evaporator based on a temperature of the storage chamber, and
delay operation of the first fan for a preset first reference period of time after the at least one of the compressor or the valve began supplying the refrigerant to the evaporator,
wherein the refrigerant supplied to the evaporator flows in through a top end of the evaporator and flows out through a bottom end of the evaporator,
wherein the first outlet is formed in an upper portion of the panel and the auxiliary outlet is formed in a lower portion of the panel, and
