摘要
综述了国内外溴化锂吸收式制冷机中吸收器的发展历史及研究现状;介绍了降膜式吸收器并分析了近些年发展起来的喷雾式吸收器的情况和各自的特点,分析得出:传热传质分离的预冷却吸收器可以对传热和传质过程分别进行强化,大大提高吸收器的工作效率,能在很大意义上节约设备耗材、节省投资,具有很高的学术和经济效益。
Overviewed the development history and the research under present conditions of the absorber in the lithium bromine refrigeration system in home and abroad. Introduced the falling-film type absorption machine and mainly analyses the spray absorber which is used in recent years. The results of the research got out that the heat and mass transfer seperated absorber can save a lot of materials and investment since it can raise the work efficiency of the absorber consumedly. It is then worthy the research both in the academy and economics.
