不凝气体对溴化锂制冷机的影响及防治

Effect of Uncondensation Air on LiBr Cooling Machine and Corresponding Protective Measures

对溴化锂制冷机而言,不凝气体指空气、氢等。不凝气体主要以外部渗入、材料腐蚀和溶液注入的方式产生。不凝气体会导致溴化锂制冷机管材腐蚀、冷凝器热交换效率降低、吸收器热交换效率降低、制冷效率下降、溶液结晶等。防治不凝气体的产生,需加强调试时的气密性试验、运行时的气密性检查、长期停机后的气密性管理和真空度的保持等措施。

This article introduces what the uncondensation air is, Where the uncondensation air comes from, How the uncondensation air influences the LiBr cooling machine and how to protect the LiBr cooling machine against the uncondensation air.
