Abstract:
1. A refrigerator comprising a main body comprising a refrigerating compartment and a freezing compartment; a first evaporator and a second evaporator corresponding to the refrigerating compartment and the freezing compartment, respectively; a compressor to compress refrigerant to be supplied to the first and second evaporators; a first fan and a second fan to supply cool air to the refrigerating compartment and the freezing compartment, respectively; an external temperature sensor to detect an external temperature of the refrigerator; a multi-directional valve to supply the refrigerant to at least one of the first evaporator for the refrigerating compartment and the second evaporator for the freezing compartment; and a control unit to operate the compressor and the multi-directional valve, and driving the first fan for the refrigerating compartment and the second fan for freezing compartment until temperatures of the refrigerating compartment and the freezing compartment reach a predetermined reference temperature, wherein, when the detected external temperature meets a low temperature condition, the control unit controls the multi-directional valve to supply the refrigerant to the first evaporator for the refrigerating compartment in the state that the compressor is operated and an operation of the first fan for the refrigerating compartment is halted.
