STARTING METHOD OF VARIABLE CAPACITY ROTARY COMPRESSOR

摘要

A method for starting a variable capacity compressor is provided to improve the reliability of a compressor by preventing chattering of a vane in initial starting. Whether a compressor is initially started(S300) or not is judged. If so, a vane is restricted to be operated in a partial load mode to prevent vane chattering(S310-S330). A difference between a suction pressure and a discharge pressure of the compressor is detected for judging whether the difference is over a predetermined value(S340). If so, the compressor is converted into a full load mode according to a temperature condition(S360). If not, the compressor is operated in a partial load mode for reducing compression capacity(S370-S380).
