Benefits of technology
The present invention provides an apparatus and method for controlling a reciprocating compressor that can enhance its operation efficiency by selecting between a general mode and a power-saving mode based on a control signal and controlling the stroke of the compressor through the selected mode. This can result in improved performance and efficiency of the compressor.
Problems solved by technology
However, the conventional apparatus for controlling an operation of the reciprocating compressor is disadvantageous in that since the ON / OFF period of the control signal inputted to the triac is varied, a transport loss of the triac itself is made and a harmonic loss generated due to the transport loss degrade efficiency of the operation of the reciprocating compressor.

An apparatus and method for controlling an operation of a reciprocating compressor are disclosed. The apparatus for controlling an operation of a reciprocating compressor includes a microcomputer for outputting a control signal for controlling a stroke of a reciprocating compressor; and an electric circuit unit for selecting one of control paths of pre-set general mode and power-saving mode according to a control signal and controlling a stroke of the reciprocating compressor through the selected control path.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a reciprocating compressor and, more particularly, to an apparatus and method for controlling an operation of a reciprocating compressor. [0003] 2. Description of the Background Art [0004] In general, a reciprocating compressor is to compress a refrigerant circulating inside a cooling device as a piston is linearly and reciprocally moving inside a cylinder. The reciprocating compressor can be roughly divided into a recipro type and a linear type depending on how the piston is driven. [0005] The recipro type reciprocating compressor is that a crank shaft is coupled to a rotating motor and a piston is coupled to the crank shaft so that the piston can be linearly and reciprocally moved by using a rotational force of the rotating motor. [0006] The linear type reciprocating compressor is that the piston is directly connected to a linear motor to allow the piston to be linearly and recipro...
