  • Refrigerator and control method therefor
    Patent number: 10544972
    Abstract: The present disclosure relates to a refrigerator and a method for controlling the same. The present disclosure provides a method for controlling the same, the method including an initial driving step of driving a compressor according to a rotation per minute (RPM) at which the compressor is driven in a previous cycle, an RPM adjusting step of increasing the RPM when an operation rate is larger than a first setting value, decreasing the RPM when the operation rate is smaller than the second setting value, and maintaining the RPM when the operation rate is between the first setting value and the second setting value, in consideration of the operation rate of the previous cycle, and a driving step of driving the compressor according to the adjusted RPM, wherein the first setting value is larger than the second setting value.

  • Refrigerator and control method thereof
    Patent number: 10422563
    Abstract: A control method includes initially operating a compressor at the same RPM as an operating RPM of the compressor during a previous cycle, adjusting the RPM in consideration of an operation rate of the previous cycle such that the RPM is increased when the operation rate is greater than a first set value, reduced when the operation rate is less than a second set value, and maintained when the operation rate is within a range between the first set value and the second set value, and operating the compressor at the adjusted RPM, the first set value being greater than the second set value.
