Used primarily as a desiccant and absorbent in lithium bromide-water absorption refrigeration systems, especially in large-scale air conditioning and industrial cooling applications. Its high affinity for water makes it effective in removing moisture from air and gases. Commonly found in water-cooled chillers where it circulates in a closed loop to absorb and release water vapor, enabling continuous cooling. Also used in some drying agents and as a source of bromide ions in chemical synthesis, including as a catalyst or reagent in organic reactions. Due to its hygroscopic nature and potential toxicity upon ingestion or prolonged exposure, it requires careful handling to avoid moisture contamination and health risks.
