摘　　要：溴化锂吸收式制冷机具有热效率高、热源广泛、能耗低以及零排放等优点,近年来得到广泛的应用。而作为强腐蚀性介质,高浓度溴化锂水溶液在循环条件下会引起碳钢、铜以及铜合金等金属材料严重的腐蚀。由高温溴化锂水溶液中的耐腐蚀性实验表明,溴化锂水溶液腐蚀性受金属材料和外界条件的影响,文章对溴化锂水溶液腐蚀性这一问题的研究进而提出防腐措施,对于溴化锂吸收式制冷机技术的发展具有重要意义,已引起人们的重视。Lithium bromide absorption chiller has been applied widely in recent yeas with its many excellent characteristics,such as high thermal efficiency,wide heat sources,low energy consumption and zero release.As a strong erosive medium,high concentration lithium bromide solution may cause serious corrosion on carbon steel,copper and copper alloy under circulation conditions.As lithium bromide water solution corrosion resistance experiment under high temperature showed that corrosion of lithium bromide water solution is influenced by metal materials and external conditions.Based on the study,the paper proposed measures to prevent corrosion which play the significant role in development of lithium bromide absorption chiller technique.
