【摘要】 为了适应国际《蒙特利尔议定书》规定的禁用ＣＦＣ和ＨＣＦＣ类物质的要求，亟待寻求它们的替代物。目前，一些制冷剂的混合物是替代ＣＦＣ和ＨＣＦＣ物质的理想制冷剂。在混合型制冷剂的筛选及空调制冷设备的开发过程中，粘度是不可缺少的参数之一，但是许多制冷剂的混合物的粘度数据还很少。考虑双分子作用模型，得出了一个制冷剂混合物粘度的预测公式，并对公式进行了简化，只要知道制冷剂液体混合物中纯物质的粘度和分子量，就可以方便地算出混合物的粘度，经验证，该公式可以满足工程实际需要更多还原

【Abstract】 To meet the restriction of the Montreal Protocol, the project to find new refrigerants to replace chlorofluorocarbon(CFC) and hydrochlorofluorocarbon(HCFC) is focused. For the time being, the mixtures of some refrigerants are considered promising alternative to old refrigerants. In the development and design of air conditioners and refrigeration equipment, viscosity is one of the necessary thermophysical properties, but the reliable viscosity data of some refrigerant mixtures are very limited. In this paper, a model of reaction between double molecules is adopted to put forward a prediction equation for the viscosity of the mixtures of some refrigerants and the equation was simplified. With this simplified equation, the viscosity of the mixtures can be calculated conveniently provided the viscosities and molecular weight of the components are given. The accuracy of the equation can meet the requirements of engineering applications.更多还原
