The refrigerants mixture has a great perspective in the thermal engineering, while the evaporation of refrigerants mixture still needs to be studied in depth. Therefore, molecular dynamics simulations were employed to investigate the evaporation process of the following refrigerants, pure refrigerant R32, R152a and R32/R152a mixtures (with mole ratio of 1:1, 3:1, and 1:3), on the Pt surface at 220 K, 250 K and 350 K, respectively. The results showed that R32 is more likely to evaporate than R152a in the simulated systems under the same conditions. The Pt substrate absorbs more R32 molecules than R152a molecules. Besides, the nucleate boiling and film boiling are found in the systems evaporating at 350 K. The results also suggest that the existence of R152a molecules will alleviate the boiling of R32 molecules, owing to the higher boiling point of R152a and the weaker adsorption capacity of R152a on the Pt surface. And the R32/R152a mixture systems own better cooling capacity than that of pure R32 and pure R152a systems.

制冷剂混合物在热工程学中具有广阔的前景，而制冷剂混合物的蒸发仍需深入研究。因此，采用分子动力学模拟研究了以下制冷剂在纯铂表面上的蒸发过程：纯制冷剂R32，R152a和R32 / R152a混合物（摩尔比为1：1、3：1和1：3）分别为220 K，250 K和350K。结果表明，在相同条件下，模拟系统中的R32比R152a更有可能蒸发。Pt底物比R152a分子吸收更多的R32分子。此外，在350 K蒸发的系统中发现了核沸腾和薄膜沸腾。结果还表明，R152a分子的存在将减轻R32分子的沸腾，由于R152a的沸点较高，而R152a在Pt表面的吸附能力较弱。与纯R32和纯R152a系统相比，R32 / R152a混合系统具有更好的冷却能力。
