Bu çalışmada, temel buhar sıkıştırmalı soğutma sisteminde enerji ve ekserji analizi yapılmıştır. Sistem, buharlaştırıcı, kompresör, kondenser ve genleşme vanası olmak üzere dört kısımdan oluşmaktadır. Her bir bileşende enerji ve ekserji dengesi kullanılmış ve temel buhar sıkıştırmalı soğutma sisteminin etkinliği ortaya konulmuştur. Çalışmada, farklı soğutucu akışkanların sistem performansına etkisini görmek amacıyla sabit ölü hal sıcaklığında (T0 = 25 oC) dört farklı gaz (R134a, R125, R141b, R423a) analiz edilmiştir. Sonuçlara göre, R134a'nın COP değeri 2,50 iken toplam ekserji yıkımı 2,31 kW'tır. R423a'nın COP değeri 0,22 iken toplam ekserji yıkımı 0,50 kW'tır. R141b'nin COP değeri 0,60 iken toplam ekserji yıkımı 7,38 kW'tır. R125'in COP değeri 0,53 iken toplam ekserji yıkımı 4,74 kW'tır.

Thermodynamic Analysis of Vapor Compression Refrigeration System with Various Refrigerants

Öz

The study analyzes energy and exergy in the basic vapor compression refrigeration system. The system consists of four parts as expansion valve, condenser, evaporator and compressor. In each component, energy and exergy balance is employed and the effectiveness of the basic vapor compression refrigeration system is presented. In the study, to evaluate the impact of different refrigerants on system effectiveness, four different gases (R134a, R125, R141b, R423a) at constant dead state temperature (T0 = 25 oC) are analyzed. According to the results, while the COP of R134a is 2.50, the total exergy destruction is 2.31 kW. While the COP of R423a is 0.22, the total exergy destruction is 0.50kW. While the COP of R141b is 0.60, the total exergy destruction is 7.38kW. While the COP of R125 is 0.53, the total exergy destruction is 4.74kW.
