| description | In order to study the performance of the new environment-friendly refrigerant mixture, chemical simulation software was used in this study to simulate the compressor exhaust temperature, compression work, evaporator evaporation temperature, system cooling capacity and COP of the non-azeotropic refrigerant R1234yf/R116/R14 under different component ratios for the three-stage self-cascading refrigeration system. The accuracy of the model is verified by comparing the existing experimental data, and the simulation results are compared and analyzed. The results show that the compressor operating conditions and evaporation temperature are close to each other under different component ratios, and the cooling capacity and COP of the system are the largest and the performance is the best when the component ratio is 0.5/0.27/0.23. In this paper, a new environmentally friendly refrigerant R1234yf is introduced into the self-cascade refrigeration system, and R1234yf/R116/R14 is used as the mixed refrigerant for simulation research, which provides a theoretical basis for its subsequent application. |
