State-of-the-art review on crystallization control technologies for water/LiBr absorption heat pumps.

Type of article: Article, IJR article

Summary

The key technical barrier to using water/lithium bromide (LiBr) as the working fluid in air-cooled absorption chillers and absorption heat-pump systems is the risk of crystallization when the absorber temperature rises at fixed evaporating pressure. This article reviews various crystallization control technologies available to resolve this problem: chemical inhibitors, heat and mass transfer enhancement methods, thermodynamic cycle modifications, and absorption system-control strategies. Other approaches, such as boosting absorber pressure and J-tube technology, are reviewed as well. This review can help guide future efforts to develop water/LiBr air-cooled absorption chillers and absorption heat-pump systems.
