A refrigerator includes a main body having cooling chambers for keeping food items therein, a base frame disposed to be movable in outward and inward directions in a lower cooling chamber disposed at a lower portion of the main body, and having a basket door at its front side, a lift frame disposed on the base frame, on which the basket is put, a fluid pressure cylinder mounted at the base frame and connected to the lift frame to lift the lift frame, and an fluid compressor connected to the fluid pressure cylinder by an fluid supply pipe and supplying compressed fluid to the fluid pressure cylinder. Accordingly, as the basket is lifted when being drawn out, a user can take out food items kept in the basket without bending his/her back, which enhances user's convenience.

Refrigerator having basket lift apparatus

Disclosed are an apparatus for controlling a driving of a reciprocating compressor capable of enhancing an efficiency by differently controlling a frequency and a stroke voltage according to a load size and capable of reducing consumption power, and a method thereof. The apparatus comprises a controlling unit for judging a load size by comparing a phase difference between a detected current and a stroke with a reference phase difference, and outputting a frequency control signal and a stroke control signal according to the judged load size.
