溴化锂冷水机组中溴化锂溶液pH值的理论计算方法

Evaluation of pH in Absorption Chillers for LiBr Water Solution

提出了欲使溴化锂溶液的ｐＨ值保持在９～１０５时需在溶液中加入ＬｉＯＨ量的理论计算公式，大大简化了精确调整ＬｉＢｒ溶液ｐＨ值的过程．分析了溴化锂溶液实测ｐＨ值与理论计算ｐＨ值差别大的原因，提出了必须使用酸度计并遵守操作规程才能精确测定ｐＨ值的观点．

Adjustment of pH value of LiBr water solution is made by calculating the quantity of LiOH and using accurate pH measurement instrument. Shown in this work is that pH between 9 to 10 5 can be controlled in the operational process.
