Hydrofluorocarbon (HFC) mixture as a long-term refrigerant substitute, the surface tension data for the design of refrigeration and air conditioning equipment is very important. In this paper, the experimental data of the surface tension of the existing mixture in the world is given, and the uniform form of the surface tension of the HFC binary mixture is given, which can reproduce the experimental data with high precision over a wide temperature range and accurately calculate the relative pure Surface tension of working fluids. Compared with the existing mixture correlation analysis. The paper provides the surface tension correlation calculation accuracy to meet the engineering application
