Abstract
A refrigerator which includes 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 compressing refrigerant to be supplied to the first and second evaporators, a first fan and a second fan supplying cool air to the compartments, respectively, an external temperature sensor detecting an external temperature of the refrigerator, a multi-directional valve supplying the refrigerant to at least one of the evaporators, and a control unit operating the compressor and the multi-directional valve, and driving the first fan and the second fan until temperatures of the compartments reach a predetermined reference temperature. 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 such that the compressor is operated and an operation of the first fan is halted.
