Evaporation of R32/R1234yf Mixture on the Wall: A Molecular Dynamics Study

Abstract

Abstract The mixed refrigerants have a great potential in the energy industry, while the micro-mechanism of evaporation of mixed refrigerants is still unclear. Therefore, molecular dynamics simulations were employed to investigate the evaporation of the R32, R1234yf and their mixture on the Pt surface at 230 K, 250 K and 350 K, respectively. The results indicate that the presence of R1234yf will suppress the evaporation of R32. The adsorption interaction between R32 and substrate is lower than that of R1234yf. The film boiling is found at high temperature evaporation. Meanwhile, the heat flux of the system decreases due to the heat transfer deterioration.
