In this study, the usage of refrigerant R1234yf was experimentally investigated with the addition of various nanoparticles instead of R134a as a working fluid in a VCRS. Firstly, the usage of pure R1234yf instead of R134a was experimentally investigated with energy and exergy approaches without any modification in the VCRS. As a result of pure refrigerant experiments, it was determined that the compressor power input increased by around 9%, cooling capacity decreased by around 8% and EER decreased by around 17% in the system using R1234yf compared to the system using R134a. Additionally, it was determined that the second law efficiency of the VCRS reduced by around 8% in the system using R1234yf compared to the system using R134a. Then, Al2O3, graphene or CNT nanoparticles were added for compensate for performance drops to the VCRS using R1234yf via compressor oil at various mass fractions. Thus, the best enhancement in the system performance parameters was obtained with the usage of R1234yf including 0.250% graphene by mass. Accordingly, it was observed that the cooling capacity of the system with R1234yf including 0.250% graphene by mass was improved up to 24% and 14% compared to the VCRS with pure R1234yf and R134a, respectively. Consequently, the EER value of the VCRS with R1234yf including 0.250% graphene by mass was enhanced up to 32% and 13% compared to the system using pure R1234yf and R134a, respectively. Additionally, the second law efficiency of the system slightly increased with the usage of R1234yf including 0.250% graphene by mass.

R134a YERİNE R1234yf KULLANILAN BUHAR SIKIŞTIRMALI SOĞUTMA SİSTEMİNDE NANOSOĞUTUCU AKIŞKANLARIN ETKİLERİNİN DENEYSEL OLARAK İNCELENMESİ

Öz

Bu çalışmada; R1234yf soğutucu akışkanının, içerisine çeşitli nanoparçacıklar eklenerek bir BSSS’de R134a yerine iş akışkanı olarak kullanımı deneysel olarak incelenmiştir. İlk olarak; R134a yerine saf R1234yf kullanımı, bir BSSS’de herhangi bir değişiklik yapılmadan enerjetik ve ekserjetik yaklaşımlarla deneysel olarak incelenmiştir. Saf soğutucu akışkan deneyleri sonucunda; R1234yf kullanılan sistemde R134a kullanımına kıyasla kompresör güç girişinin yaklaşık %9 arttığı, soğutma kapasitesinin yaklaşık %8 azaldığı ve EER değerinin yaklaşık %17 azaldığı tespit edilmiştir. Ayrıca, BSSS’nin ikinci yasa veriminin, R1234yf kullanılan sistemde R134a kullanımına kıyasla %8 civarında azaldığı tespit edilmiştir. Daha sonra, R1234yf kullanan BSSS’ye performans düşüşlerini telafi etmek için Al2O3, grafen veya CNT nanopartikülleri çeşitli kütlesel oranlarda kompresör yağı aracılığıyla eklenmiştir. Böylece, sistem performans parametrelerindeki en iyi artış kütlece %0,250 grafen içeren R1234yf kullanımı ile elde edilmiştir. Buna göre, kütlece %0,250 grafen içeren R1234yf’li sistemdeki soğutma kapasitesinin, saf R1234yf ve R134a’lı sistemlere kıyasla sırasıyla %24 ve %14’e kadar iyileştirildiği gözlemlenmiştir. Sonuç olarak, kütlece %0,250 grafen içeren R1234yf’li BSSS’nin EER değeri, saf R1234yf ve R134a kullanılan durumlara kıyasla sırasıyla %32 ve %13’e kadar artırılmıştır. Ayrıca, kütlece %0,250 grafen içeren R1234yf kullanımı ile sistemin ikinci yasa verimliliğinde de az miktarda bir artış olmuştur.
