A refrigerator having an opening degree control means and a control method thereof which have an opening degree control means for controlling a refrigerant flow provided into each evaporator, and thus enhance an energy efficiency, in a refrigerator which independently cools or maintains the freezing and refrigerating compartments at different temperatures by including an evaporator in each of the freezing and refrigerating compartments. The refrigerator includes: a compressor; a condenser; a refrigerating compartment and a freezing compartment which are divided to be separately cooled; first and second evaporators which are respectively mounted into the refrigerating and freezing compartments; a refrigerating fan and a freezer fan which are respectively mounted in the refrigerating and freezing compartments; opening degree control means for varying a pressure difference between a high pressure side and a low pressure side by controlling a flow of the refrigerant; and control unit for controlling the aforementioned components. As a result, the present invention varies the opening degree of the opening control means in order to vary a pressure difference between the high pressure side and the low pressure side, thereby lowering a power driving loss of the compressor and enhancing an energy efficiency.
