摘　　要：应用一套通用型流体热物性方程对HFC类致冷工质的饱和密度、蒸汽压和汽化潜热进行计算。结果表明,本方法不仅使用简便,而且也十分精确。能够得到工程界广泛的使用。The saturated densities, vapour pressures, and latent heats of vaporization for HFC working substances of refrigeration are calculated by using a set of general equations of thermophysical property of liquids. The calculated results show that these prediction methods are not only simple and convenient, but quite accurate as well. It is sincerely hoped that these methods will find application in engineering.
