摘要：

In this paper, based on the energy analysis method is established across the critical CO2 two-stage compression refrigeration system simulation model. LabVIEW software was used to write simulation programs, and the operation of the refrigeration system under different working conditions was simulated through different parameter Settings. Data analysis of the simulation results was conducted to explore the main factors that affect the COP of the system. The results show that the COP of the system increases with the rise of suction superheat of the compressor. As the evaporation temperature increases, the COP of the system gradually increases. There is an optimal intermediate pressure corresponding to COP
