OPERATION CONTROL METHOD OF INVERTER REFRIGERATOR

摘要

PURPOSE: An operation control method of an inverter refrigerator is provided to decrease power consumption by regulating the rotation number of a DC motor installed in a compressor based on the types of a use condition. CONSTITUTION: A control system unit(60) varies the rotation number of a DC motor(51a) in stages by the types of a use condition based on a cooling load. Thereby, when a temperature in a cooling chamber(56) or the times of opening and closing a cooling chamber door(57) is changed during the operation, the rotation number of the DC motor is varied in stages by the changed use condition.
