Bazı
endüstriyel soğutma uygulamaları için düşük sıcaklıklara ihtiyaç duyulur. Tek
kademeli soğutma sistemleri ile bu sıcaklığı elde etmek oldukça zor ve ekonomik
açıdan avantajlı değildir. Bu nedenle daha düşük sıcaklıkta soğutma
uygulamalarında kaskad soğutma sistemleri tercih edilir.

 

Bu çalışmada, yeni nesil soğutucu akışkan çiftlerinin kullanıldığı kaskad
soğutma sisteminin performans analizi yapılmıştır. Kaskad sisteminde ozon delme
potansiyeli (ODP) sıfır olan ve küresel ısınma potansiyeli (GWP) değeri düşük
R454C/ R1234ze, R454C/ R1234yf, R454C/R717, R744/R290 ve R744/R717 soğutucu
akışkan çiftleri kullanılmıştır. Yapılan analizler sonucunda en yüksek COP
değerlerine R454C/R717 akışkan çifti kullanıldığında ulaşılmıştır.

Comparative Performance Analysis of Cascade Refrigeration System Using Low GWP Refrigerants

Öz

Some industrial
cooling applications require low temperatures. With single stage refrigeration
systems, it is difficult to obtain this temperature and is not economically
advantageous. Therefore, cascade refrigeration systems are preferred for lower
temperature cooling applications. In this study, the performance analysis of the
cascade refrigeration system using the new generation of refrigerant pairs was
performed. In the cascade system, GWP R454C/
R1234ze, R454C/ R1234yf, R454C/R717, R744/R290 ve R744/R717 refrigerant pairs were used. As a result of
analyzes, the highest COP values were reached when the R454C/R717 fluid pair was used.
