Refrigerator

A refrigerator comprising:

• a refrigeration cycle comprising:
• a compressor,
• a condenser,
• a plurality of pressure reducing devices, and
• an evaporator;
• a first refrigerant flow path branched at a point downstream of the condenser, comprising one of the plurality of pressure reducing devices, and connected to the evaporator;
• a second refrigerant flow path branched at a point downstream of the condenser, comprising another of the plurality of pressure reducing devices, and connected to the evaporator;
• a switching valve configured to individually switch an open or closed state of the first refrigerant flow path and of the second refrigerant flow path;
• and
• a processor configured to:
• adjust a flow rate of refrigerant flowing in the first refrigerant flow path and in the second refrigerant flow path by individually duty-controlling an opening and closing time of the first refrigerant flow path and of the second refrigerant flow path by controlling the switching valve,
• set a duty ratio of a duty control for the first refrigerant flow path to be greater than a duty ratio of a duty control for the second refrigerant flow path in response to an amount of cold air exchanging heat with the first refrigerant flow path being greater than an amount of cold air exchanging heat with the second refrigerant flow path, and
• set a duty ratio of the duty control for the first refrigerant flow path to be less than a duty ratio of the duty control for the second refrigerant flow path in response to that an amount of cold air exchanging heat with the first refrigerant flow path being less than an amount of cold air exchanging heat with the second refrigerant flow path.
