ABSTRACT:
An improved apparatus for controlling a refrigerator equipped with a linear compressor which is capable of achieving an optimum driving efficiency of the system irrespective of an operational condition of a refrigerator by providing the refrigerator with a linear compressor. The apparatus includes an operation ratio computation unit for computing an operation ratio of a compressor, a cooling capacity computation unit for computing a cooling capacity based on a stroke distance of a piston of the compressor, and a controller for maintaining a constant operation ratio by controlling the piston stroke distance in accordance with the operation ratio and the cooling capacity.
