Problems solved by technology

[0018] However, in the case of using the conventional control device for the operation of the reciprocating compressor, the stroke estimation value cannot be accurately calculated due to the parameters of the electric motor of the reciprocating compressor and the mechanical error of the reciprocating compressor, so the reciprocating compressor cannot be precisely controlled.

Abstract

An apparatus and method are disclosed to control an operation of a reciprocating compressor capable of precisely controlling an operation (stroke) of a reciprocating compressor regardless of a parameter of an internal motor of the reciprocating compressor and a mechanical error of the reciprocating compressor. The apparatus for controlling an operation of a reciprocating compressor which determines a stroke estimate value corresponding to a point when a discharge valve of the reciprocating compressor is opened as a stroke reference value, and controls a voltage applied to the reciprocating compressor according to the determined stroke reference value.

Description

technical field [0001] The present invention relates to a compressor, and more particularly, to a control device for the operation of a reciprocating compressor and a control method thereof. Background technique [0002] In general, reciprocating motor compressors (hereinafter referred to as "reciprocating compressors" for brevity) run by linear reciprocating motors that do not have a crankshaft that converts rotational motion to linear motion have lower friction losses and therefore Can provide higher compression efficiency than other compressors. [0003] When a reciprocating electric compressor is used in a refrigerator or an air conditioner, the refrigeration capacity can be controlled by changing the compression ratio of the compressor by changing the stroke voltage applied to the reciprocating motor of the compressor. [0004] The following will refer to figure 1 to describe the traditional control of a reciprocating electric compressor. [0005] figure 1 is a bloc...
