Investigation of inlet air pressure and evaporative cooling of four different cogeneration cycles

Abstract The objective of this study was to search the effects inlet air compressor pressure and evaporative cooling four different cogeneration plants that are absorption (ab), basic (bsc), heating (airh), fuel (airfh) systems by using first law second thermodynamics, exergy analysis methods. For analysis, a program is written author in FORTRAN programming language. Decreasing atmospheric or increasing installation altitude increases Z factor (ratio lost useful exergy) cycles about 10–13%. Also, decreasing decreases specific work 25–28%, energy saving ratio 29–30%. method water spray especially summer months, humidity can be obtained. By method, decreased for 0.5–2%. increased 1.2–6%.
