摘　　要：该文提出预冷却绝热吸收的空冷溴化锂吸收式制冷循环的吸收器设计方案 ,设计加工了一个溴化锂水溶液绝热降膜吸收的循环实验装置。实验研究了在湍流情况下 ,溴化锂水溶液在竖直光管外绝热降膜吸收的传质性能。研究了溶液浓度、温度。An experimental facility of lithium bromide aqueous solution with adiabatic falling film outside the absorber tube was built and the investigation was carried out for water vapor absorption performance of lithium bromide aqueous solution outside an ending-up smooth copper tube under different working conditions. The effects of solution concentration, solution temperature, vapor pressure and surfactant addition on absorption performance were described.
