Effects of Surfactants on Absorption of Water Vapor into Aqueous LiBr Solution[J]. Journal of refrigeration, 2005, 26(2): 29-33. DOI: 10.3969/j.issn.0253-4339.2005.02.006.
The purpose of this study is to prepare some basic experimental data for mechanism study of Marangoni effect and to look for some more effective additives to substitute 2-ethyl-1-hexanol or 1-octanol which are widely used in lithium bromide absorption refrigeration system. In present study
absorption of water vapor into the 62 wt% lithium bromide solution with several six-carbon and seven-carbon alcohol additives such as 4-methyl-2-pentanol
2-ethyl-1-butanol
1-hexanol
2
4-dimethyl-3-pentanol
4-heptanol
2-heptanol
and 1-heptanol were investigated by using a simple stagnant pool absorber. The results show that effects of 1-hexanol and 1-heptanol on absorption of water vapor into aqueous lithium bromide solution are better than those of 2-ethyl-1-hexanol.
