In an apparatus and a method for controlling operation of a linear compressor using a pattern recognition , includes a displacement calculating unit calculating a displacement by being inputted the current detected in the current detecting unit and the voltage detected in the voltage detecting unit, a pattern recognition unit being inputted the displacement outputted from the displacement calculating unit and the current outputted from the current detecting unit and detecting a pattern by using a trace corresponded to the displacement and the current, a stroke controlling unit being inputted a pattern from the pattern recognition unit and outputting a switching control signal according to the inputted pattern, and an electric circuit unit being inputted the switching control signal outputted from the stroke controlling unit and outputting a certain voltage to the linear compressor, accordingly it is possible to perform a TDC control of a piston considering an error due to non-linearity characteristics, improve an operation efficiency of a linear compressor and have a wide and precise control region.
Description
technical field [0001] The present invention relates to an apparatus and method for controlling the operation of a linear compressor capable of operating a linear compressor by inputting a stroke reference value, and more particularly, to a method for controlling a linear compressor using pattern recognition An apparatus and method of operation capable of operating a linear compressor at optimal efficiency by recognizing a relationship between current and displacement as a pattern. Background technique [0002] Typically, the role of the compressor is to pressurize the refrigerant vapor to help condense the refrigerant vapor evaporated in the evaporator more easily. By running the compressor, the refrigerant transfers heat from a cold place to a hot place by repeating the process of condensation and evaporation as it circulates through the refrigeration unit. [0003] Recently, various types of compressors are employed, and a reciprocating compressor is generally used. The...
