Research and test of IPLV in air-bearing centrifugal compressor
This paper tested and analysed on the Integrated Part Load Value(IPLV)of air-bearing centrifugal compres-sors,aiming to evaluate their energy efficiency under different load conditions.Based on the testing method of JB/T 12843-2016 standard,the performance coefficients of the compressor under different loads were derived through experimental data col-lected under various test conditions,the IPLV of the compressor can reach 8.60 kW/kW.This result indicates that the air-bear-ing centrifugal compressor is an excellent energy-saving product,especially showing superior performance under high load con-ditions.However,as its performance coefficient under low load conditions is lower than that of magnetic-bearing centrifugal compressors,there is still significant room for improvement in its IPLV.
