초록

A method is provided for controlling operation of a compressor having an inlet and an outlet, a variable geometry diffuser communicated with the outlet, and inlet guide vanes communicated with the inlet, wherein the method includes the steps of: determining a loading parameter indicative of onset of surge; and independently controlling the inlet guide vanes and the variable geometry diffuser based upon the loading parameter so as to allow increase in efficiency and stable operation of the compressor.

청구항

We claim: 1. A method for controlling operation of a compressor having an inlet and an outlet, a variable geometry diffuser communicated with the outlet, and inlet guide vanes communicated with the inlet, comprising the steps of: determining a loading parameter indicative of onset of surge; and independently controlling the variable geometry diffuser and at least one of compressor speed and the inlet guide vanes based upon the loading parameter so as to allow increase in efficiency and stable operation of the compressor, wherein the independently contr...
