Abstract

The present work is devoted to investigate compressor performance (positive
displacement or dynamic compressor) from two different points of view that are;
energy and exergy. The studied compressor parameters are; compressor polytropic
efficiency, compressor pressure ratio, inlet temperature, and inlet humidity. The
effect of these parameters on compressor specific work consumption, compressor
operating range, energy destruction, energy destruction ratio, and the first and second
law efficiencies are demonstrated. The results show how the compressor behaves
under different conditions. Also, the results illustrate that first and second law
efficiencies provide quantitative and qualitative compressor performance
assessments. The result charts help in selecting different types of compressors that
having higher second law efficiency or having less exergy destruction ratio. The
present paper may give an insight to understand deeply compressor performance and
how to evaluate or choose the compressor with less exergy losses ratio.
