A:Answer The linear compressor used in the LG LG - 23.8 Cu. Ft. Bottom-Freezer Refrigerator , Model # LBC24360SW has no crank mechanism and its piston is oscillated by linear motor and helical coil spring. Due to the simple mechanism, its mechanical loss is much less than conventional crank
driven compressors.
• Using the moving magnet type linear oscillating motor, its motor efficiency goes more
than 90%.
• With simple electronics, cooling capacity could be modulated to get better system
efficiency.
The LG linear compressor is 20~ 30% more efficient than most efficient current crank driven
compressors...^IFV
