3E Analysis of Ejector Compression Absorption Cascade Cycle Working with Environmental Friendly Refrigerants

Öz

The low electrical consumption of the compression absorption cascade cycle and its potential to work with low-grade generation temperature qualify it to become an attractive system for refrigeration production, in this work, the performance of the ejector compression absorption cascade cycle (ECACC) was studied using 11 refrigerants with low GWP and ODP for vapor compressor section, the performance comparison results show that the R744 has the better COP and the exergy efficiency then the effect of generation temperature on the performance of ECACC is carried out. Also, the destruction of exergy destruction of the main component of ECACC is analyzed. The annual cost includes the investment, operating, and environmental costs considered. Also, the following results found in the studied cycle show that the thermodynamic performance is at maximum in a specific generation temperature and then decreases with an increase in the generation temperature, contrary to the annual cost. The absorber, the generator, the cascade heat exchanger, the solution heat exchanger, and the condenser are responsible for almost all exergy destruction of ECACC followed by the compressor and the ejector, respectively

Çevre Dostu Soğutucularla Çalışan Ejektör Sıkıştırma Absorpsiyon Kademeli Döngüsünün 3E Analizi

Öz

Sıkıştırma emilimli kademeli çevrimin düşük elektrik tüketimi ve düşük dereceli üretim sıcaklığıyla çalışma potansiyeli, onu soğutma üretimi için çekici bir sistem haline getirmektedir. Bu çalışmada, ejektör sıkıştırma emilimli kademeli çevrimin (ECACC) performansı, buhar kompresör bölümü için düşük GWP ve ODP'ye sahip 11 soğutucu kullanılarak incelenmiştir. Performans karşılaştırma sonuçları, R744'ün daha iyi COP ve ekserji verimliliğine sahip olduğunu göstermiştir, ardından üretim sıcaklığının ECACC'nin performansı üzerindeki etkisi incelenmiştir. Ayrıca, ECACC'nin ana bileşeninin ekserji yıkımının yıkımı analiz edilmiştir. Yıllık maliyet, dikkate alınan yatırım, işletme ve çevre maliyetlerini içerir. Ayrıca, incelenen çevrimde bulunan aşağıdaki sonuçlar, termodinamik performansın belirli bir üretim sıcaklığında maksimum olduğunu ve daha sonra yıllık maliyetin aksine üretim sıcaklığındaki artışla azaldığını göstermektedir. ECACC'nin ekserji yıkımının neredeyse tamamından absorber, jeneratör, kaskad ısı değiştirici, çözelti ısı değiştirici ve kondenser sorumludur, bunları sırasıyla kompresör ve ejektör takip eder.
