Title: REFRIGERATOR FOR IMPROVING STABILITY OF LINEAR COMPRESSOR, AND CONTROL METHOD THEREFOR
Abstract:
A method for controlling a refrigerator using a linear compressor (30), the method comprising: controlling the linear compressor (30) to run, when initially powered on, for a preset period of time (T1) at a preset input power, the preset input power being greater than a normal startup input power matching the linear compressor (30) and being less than or equal to the maximum input power of the linear compressor (30); and, when a startup mode begins, turning off part of a refrigerant loop, such that the pressure drop of the linear compressor (30) at the exhaust side is smooth at the beginning of the startup, thereby protecting the compressor.
