| 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. | ||||
