摘要
HCFC-123是一种较为理想的 CFC-11的替代物,可用作水冷机组制冷剂以及泡沫塑料的发泡剂。在 Weber、 Kubota、 Yamashita、 Morrison和 Mae-zawa等学者的 HCFC-123饱和蒸气压试验数据的基础上,经过仔细分析,采用稳健回归方法进行了处理,筛选出一套由121组数据组成的综合数据,进而拟合得到适用范围较宽(273.15~456.96 K)精度良好的 HCFC-123蒸气压方程,具有较高的实际应用价值。
The vapor pressure data of HCFC-123 as reported by Weber, Kubota et al, Yamashita et al, Morrison and Maezawa et al were evaluated separately and a set of vapor pressure data with reasonable accuracy was obtained. Based on this data set, a Wagner type equation is proposed. This equation contains only four coefficients and correlates the measured vapor pressures with high accuracy. The range of temperature is from 273.15 to 456.96 K
