自30年代初引入卤代烃化合物以来，卤代烃化合物作为制冷剂在工业和商业上的应用越来越多。这些制冷剂是稳定、不可燃、无味的有机化合物，具有低毒性和高电阻。高效设计使用特定制冷剂的制冷系统或任何其他系统的基本前提之一是了解特定流体的热物理性质。在一系列状态和相位中，已知的最不准确的热物理性质之一是粘度。卤代烃化合物的多种工业应用需要准确地了解其粘度及其对压力和温度的依赖性，以预测流体流动和传热现象。 此外，精确的数据可以产生重要的分子参数，以及给定物质的热力学性质数据。引用:ASHRAE交易，第76卷，第1部分，旧金山，CA

Ever since their introduction in the early thirties, the halogenated hydrocarbon compounds have found increasing use for industrial and commercial applications as refrigerants. These refrigerants are stable, nonflammable, odourless, organic compounds that h.ave a low toxicity and a high electrical resistance.One of the essential prerequisities for an efficient design of a refrigeration system, or any other, that utilizes a certain refrigerant is the knowledge of the thermophysical properties of that particular fluid. One of the thermophysical properties which is known with the least accuracy over a range of states and phases is the viscosity. Diversified industrial application of the halogenated hydrocarbon compounds call for accurate information of their viscosity and its dependence on pressure and temperature for prediction of fluid flow and heat transfer phenomenon. Furthermore, accurate data can yield important molecular parameters and also thermodynamic property data for a given substance.
