Abstract: A refrigerator is provided. The refrigerator includes a plurality of refrigerant flow paths, configured to reduce the drift of the refrigerant. The refrigerator includes a refrigeration cycle including a compressor, a condenser, a plurality of refrigerant flow paths branched at a downstream of the condenser, the plurality of refrigerant flow paths each including a pressure reducing device, and an evaporator connected to the plurality of refrigerant flow paths, and a processor including a switching valve configured to individually switch an open or closed state of each of the plurality of refrigerant flow paths, the processor being configured to adjust a flow rate of refrigerant flowing in each of the plurality of refrigerant flow paths by individually duty-controlling an opening and closing time of each of the plurality of refrigerant flow paths by controlling the switching valve.
