Operation control method of inverter refrigerator compressor

摘要

PURPOSE: A lubrication mode setting method for a compressor of an inverter refrigerator is provided to reduce a noise while allowing the lubrication to be performed at a frequency lower than the resonance frequency band. CONSTITUTION: A method includes a first step of setting a lubrication mode start and stop frequency, lubrication time, and a resonance frequency band at an early stage of the operation and determining whether the lubrication mode start frequency is reached, a second step of starting the lubrication by varying a speed increasing rate into a predetermined angle and determining whether a predetermined lubrication time has lapsed if the lubrication mode start frequency is determined as reached in the first step, and a third step of setting a current operation frequency by sensing the interior temperature of the refrigerator and switching into a normal operation if the lubrication time is determined as lapsed in the second step.
