摘要
三氟碘甲烷是一种新开发的制冷剂替代物 ,具有良好的环境性能和安全性能。介绍了三氟碘甲烷 ( CF3 I)热物理性质的研究成果 ,包括临界参数的实验数据以及饱和气液密度、饱和蒸气压、汽化潜热、p VT性质、第二 virial系数、理想气体比热容、表面张力、粘度、导热系数等的关联式 ,并与文献数据进行了比较 ,分析了实验数据对关联式的偏差。
Trifluoroiodomethane (CF 3I) is a new refrigerant, which is nonflammable, nontoxic and environmentally friendly. The new thermophysical property data of trifluoroiodomethane (CF 3I) developed by authors are summarized. Experimental data of critical parameters, and the correlations of saturated liquid and vapor density, enthalpy of vaporization, vapor pressure, pVT properties, second virial coefficient, ideal gas heat capacity, surface tension, viscosity and thermal conductivity are obtained in this paper. Literature data for the thermophysical property of CF 3I are compared with the present results. The correlations and experimental data published in this paper can be used for optioning refrigerants in engineering application.
