Inverter Compressor for a refrigerator and Controlling Method for an Inverter Compressor for a refrigerator

摘要

The present invention relates to an inverter compressor of a refrigerator and a control method of the refrigerator inverter compressor. In order to lubricate the compressor with lubricating oil included in the refrigeration cycle, the present invention comprises: a lubricating mode step of maintaining the compressor at an operating speed of a first set RPM for a set time; A refrigerant load sensing step of sensing a load of the refrigerant applied to the compressor according to a current value supplied to the compressor in the lubrication mode step; One of a plurality of operation modes of the compressor is selected according to the load sensed in the refrigerant load detection step, and the compressor is driven according to a second set RPM according to the corresponding operation mode, and the plurality of operation modes are each operation of the compressor. It provides a method for controlling an inverter compressor of a refrigerator, wherein the speeds are different from each other.
