    摘要: A BLDC motor phase commutation method is provided, which can correctly detect phase commutation timing and position detection timing of a BLDC motor in a compressor to stabilize rotation and RPM of the compressor, thereby minimizing noise and vibration. When the BLDC motor rotates through a mechanical angle corresponding to one period, the BLDC motor operates according to a first scheme in which operation of the BLDC motor in the first phase commutation section of a period is performed in the same manner as in the last phase commutation section of a period immediately prior to the period. After the BLDC motor switches to sensorless mode, the BLDC motor operates according to a third scheme in which the first phase commutation section of a period has a time interval equal to the average of time intervals of first phase commutation sections of periods prior to the period.

    摘要: A refrigerator includes a defrosting heater. An outdoor air temperature sensor senses a temperature of outside air. A defrosting time period of the heater is set as a function of the outside air temperature. If it is determined that the temperature sensor is inoperative, i.e., if the sensor indicates that the outside air temperature is above 50.degree. C. or below -50.degree. C., the defrosting period which is set is the same, regardless of whether the sensor indicates the outside air temperature to be above 50.degree. C. or below -50.degree. C.
