Performance Simulation of Three-Stage Auto-Cascade Refrigeration System Based on R1234yf/R116/R14 Mixed Refrigerant
To study the performance of a new environmentally friendly refrigerant mixture, the chemical simulation software Aspen Plus was used to simulate the compressor exhaust temperature, compression work, evaporator evaporation temperature, system cooling capacity, and COP of the nonazeotropic refrigerant R1234yf/R116/R14 under different component ratios for a three-stage self-cascading refrigeration system. The accuracy of the model was verified by comparing it with existing experimental data. Additionally, the simulation results were compared and analyzed. The results reveal that the compressor operating conditions and evaporation temperature were close to each other under the different component ratios, the cooling capacity and COP of the system were the largest, and the performance was the best when the component ratio was 0.50/0.27/0.23. This study has provided a theoretical basis for applying the R1234yf refrigerant in refrigeration systems.
