PURPOSE: Provided is a method for controlling a Kimchi refrigerator which measures a load amount using a measured difference in temperatures and differently controlling an initial cooling speed according to the load amount.CONSTITUTION: MICOM respectively receives inputs of sensing values of a first temperature sensor and a second temperature sensor. If the inputted deviation greater than a first set value, a temperature inside is controlled to rapidly drop so that is lower than a lower control limit of a control temperature. If the inputted deviation less than a second set value, a temperature inside is controlled to slowly drop so that is higher than the lower control limit of a control temperature. If an initial power of a Kimchi refrigerator is permitted, the refrigerator is received sensing values of the first temperature sensor and the second temperature sensor, respectively. The first temperature sensor is provided at the upper part of the Kimchi refrigerator and the second temperature sensor is provided at the bottom of the Kimchi refrigerator.COPYRIGHT KIPO 2013[Reference numerals] (AA) Start (BB) No (CC) Yes (DD) End (S10) Initial power is approved?
