置。[Claims for Utility Model Registration] 1. A refrigerator rotation speed control device that adjusts and controls the motor rotation speed of a refrigerant compressor using a frequency control circuit,
A first temperature sensor that detects the case temperature of the compressor and a second temperature sensor that detects the ambient temperature of the refrigerator are connected to the frequency control circuit, and the frequency control circuit responds to the temperature difference detected by the temperature sensor. A rotation speed control device for a refrigerator, characterized in that the motor rotation speed is controlled when the compressor is started. 2 The frequency control circuit has a comparison calculation circuit that compares and calculates the detection signals from the first and second temperature sensors, and when the temperature difference from the temperature sensors is less than a predetermined value, the frequency control circuit causes the compressor to rotate at a low speed for a certain period of time. A rotation speed control device for a refrigerator according to claim 1 of the utility model registration claim. 3. The rotational speed control device for a refrigerator according to claim 1, wherein the second temperature sensor is installed at a location that is not subjected to the inlet action or endothermic action of the condenser and evaporator of the refrigerator.
