This seminar explores how experimentally collected indicator diagrams (pressure-volume curves) can be used to minimize losses in positive displacement compressors. This analysis is particularly relevant for optimizing the energy efficiency of compressors being modified to operate with new, low-GWP refrigerants. Experimental results for spool, screw, and scroll compressors are used to illustrate how data can be reduced and used to calculate losses. The presenters also explores how operating conditions and compressor speeds impact these losses, and how the results can be used to predict the efficiency improvements possible through improved designs.
