Abstract:
In a control method for a refrigerator including a compressor, a condenser, a freezing compartment temperature sensor and a refrigerating compartment temperature sensor, a freezing evaporator, a refrigerating evaporator being an intercooler evaporator, a freezing fan and a refrigerating fan, and a direction control valve for selectively directing a refrigerant discharged from the condenser to the first evaporator or the second evaporator, a control method for the refrigerator, comprising the steps of: (a) determining whether a refrigerating compartment temperature sensed by the refrigerating compartment temperature sensor reaches a refrigerating compartment set temperature to determine a steady state of the refrigerating compartment; (b) if it is determined that the steady state of the refrigerating compartment in the step (a), switching the direction control valve, and allowing a refrigerant to firstly pass the refrigerating evaporator; (c) if the direction control valve is switched in the step (b), driving the refrigerating fan for a predetermined time simultaneously driving the freezing fan; and (d) after the refrigerating fan is driven for the predetermined time in the step (c), stopping the refrigerating fan.
