  • Apparatus for controlling operation of reciprocating compressor
    Patent number: 7385368
    Abstract: An apparatus for controlling an operation of a reciprocating compressor includes a inductance increasing device connected to a motor of the reciprocating compressor, so that a surge current generated when power is applied to the reciprocating compressor at an initial stage is reduced and thus an initial stroke of the reciprocating compressor is reduced. Accordingly, operational efficiency of the reciprocating compressor is improved.
    Type: Grant
    Filed: April 14, 2004
    Date of Patent: June 10, 2008
    Assignee: LG Electronics Inc.
    Inventors: Eon-Pyo Hong, Kyeong-Bae Park, Tae-Hee Kwak, Ki-Chul Choi, Sung-Hyun Ki
