るよう構成されたことを特徴とする冷凍冷蔵庫。 In a refrigerator-freezer that includes an electric compressor for compressing refrigerant with a variable operating frequency and a control device that controls the operating frequency of the electric compressor, the control device has an internal temperature control unit that detects the internal temperature. a detector;
An internal temperature setting device for setting the internal temperature is provided, and the control device detects the load state of the internal storage based on the output signals of the internal temperature detector and the internal temperature setting device, and controls the electric compressor. The temperature is controlled to the set temperature in continuous operation when the load is large and in intermittent operation when the load is small, and at a constant frequency higher than the minimum frequency when the electric compressor transitions from a stopped state to an operating state under intermittent operating conditions. A refrigerator-freezer characterized by being configured to perform time-based operation control.
