Abstract
The present invention relates to an apparatus and method for controlling the operating speed of a compressor of an inverter refrigerator. In an apparatus or method embodying the present invention, one knows the operating speeds which will cause the compressor to experience resonant vibrations. When it is necessary to change from a first operating frequency to a second operating frequency, and a resonant frequency band is located between the first and second frequencies, the controller will accelerate the rate of change of the operating frequency as it passes through the resonant frequency band to minimize the amount of time that the compressor is operating within the resonant frequency band.
