Two position for the booster compressor are proposed (between the generator and the condenser, or between the cascade condenser and the absorber). the results show that using a compressor between the generator and the condenser improves the COP and the second law efficiency by 68% and 24% respectively and enhances the capital cost of the cycle by 31%, while using the compressor between the evaporator and the absorber can increase the COP and the second law efficiency of the cycle by 79% and 31%, respectively and decrease the cost of the cycle by 40%. Furthermore, the effect of compressor pressure ratio,condensor temperature, generator temperature, cascade condenser temperature and compression section evaporator temperature on thermodynamic and economic performance of the cycle is analyzed. The results indicate that the two hybrid systems can improve the performance of the cycle and locating the compressor between the evaporator and the absorber can show better performances.}, keywords = {cascaded compression-absorption refrigeration,energy,Exergy,Economic Analysis,Compressor}, title_fa = {تحلیل انرژی، اگزرژی و اقتصادی یک سیکل بهبود یافته تبرید هیبریدی آبشاری جذبی-تراکمی}, abstract_fa = {در این مقاله، استفاده از یک کمپرسور کمکی، به منظور بهبود عملکرد یک سیکل تبرید آبشاری جذبی-تراکمی از منظر ترمودینامیکی و اقتصادی مورد بررسی قرار گرفته است. نتایج نشان می دهد که استفاده از کمپرسور کمکی بین ژنراتور و کندانسور، ضریب عملکرد و راندمان قانون دوم سیکل را به ترتیب 68 % و 24 % افزایش داده و هزینه های کلی سیستم را 31 % کاهش می دهد. در مقابل، قرارگیری کمپرسور بین اواپراتور و جاذب موجب افزایش 79 درصدی ضریب عملکرد، افزایش 31 درصدی راندمان قانون دوم و کاهش 40 درصدی هزینه های سیکل می گردد.}, keywords_fa = {تبرید آبشاری جذبی تراکمی,انرژی,اگزرژی,تحلیل اقتصادی,کمپرسور}, url = {https://jmep.isme.ir/article_244445.html}, eprint = {https://jmep.isme.ir/article_244445_60475a027b259b9367e2d9486097ec03.pdf} }
