Thermodynamic Analysis of Vapor Compression Refrigeration System with Various Refrigerants
Year: 2025
Type: article
Abstract: 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.
