Abstract
A control method and control system of a refrigerator with an inverter compressor. The control method includes: calculating the total cooling amount needed by a compartment to be cooled within a unit time; taking the total cooling amount as a first power of the inverter compressor and calculating a first frequency of the inverter compressor operating at the first power; and controlling the inverter compressor to operate at the first frequency. The present invention effectively controls the power consumption amount while satisfying the refrigerator cooling condition by calculating the total cooling amount needed by a refrigerator compartment within a unit time and adjusting the frequency of the inverter compressor.
