Measurements of crystallization temperature in the H/sub 2/O-LiBr-salt system

摘要

To develop a high-solubility three-component absorbent (H/sub 2/O/LiBr/Salt) suitable for an absorption refrigerator, the effect of twenty-four inorganic salts on the crystallization temperature depression was studied. The molar fraction of H/sub 2/O/LiBr/Salt was constant at 0.722/0.208/0.070, and a correlation between the specified density of absorbent and the crystallization temperature was obtained. The salts were differentiated in three groups regarding their effects on the crystallization temperature compared with the H/sub 2/O/LiBr system. Furthermore a correlation between the volume expansion of absorbent and vapour pressure of water was discussed.
