Lithium bromide is an inorganic compound with strong water absorption, low vapor pressure, and good chemical stability. Its unique physicochemical properties make it important in multiple industrial fields. The core application industries and specific scenarios are as follows:
1. Central air conditioning and refrigeration industry
This is the main application area of lithium bromide. Lithium bromide aqueous solution is the core working fluid of lithium bromide absorption chiller, which utilizes the strong water absorption of lithium bromide to achieve refrigeration through a "absorption evaporation condensation" thermal cycle, without relying on refrigerants such as Freon, and has both environmental and energy-saving advantages. Lithium bromide absorption chillers are widely used in central air conditioning systems in large shopping malls, office buildings, hospitals, hotels, industrial plants, and other places. They are particularly suitable for combining with industrial waste heat or waste heat resources such as thermal power plants and steel plants to achieve energy cascade utilization and significantly reduce related refrigeration energy consumption.
2. Chemical industry
In chemical production, lithium bromide can be used as a desiccant and dehydrator, commonly used in organic synthesis reactions to remove trace amounts of water from materials and improve reaction purity and efficiency; Meanwhile, due to the controllable corrosiveness and strong thermal stability of its aqueous solution, it can also be used as a heat transfer medium in certain chemical processes for heat transfer under high-temperature conditions. In addition, lithium bromide can also be used as a raw material for the preparation of other bromides such as sodium bromide and potassium bromide, providing a basic intermediate for the production of chemical products.
3. Pharmaceutical industry
Lithium bromide has specific applications in the pharmaceutical field, with sedative and anticonvulsant pharmacological effects. It has been used to prepare sedative drugs to alleviate symptoms such as neurasthenia and insomnia; Meanwhile, in some drug synthesis processes, lithium bromide can serve as a catalyst or co solvent to improve the solubility and reactivity of drug intermediates, assisting in drug purification and preparation.
4. New energy and energy storage industry
With the development of new energy technologies, the application of lithium bromide in the field of energy storage is gradually expanding. The energy storage system based on lithium bromide absorption cycle can convert electrical energy into thermal energy for storage. During low electricity consumption periods, low-priced electricity can be used to produce hot water. During high electricity consumption periods, the thermal energy can be converted into cold or heat energy through lithium bromide units, achieving "peak shaving and valley filling". It is suitable for photovoltaic and wind power supporting energy storage projects, improving the utilization rate of renewable energy.
5. Other specialized industries
In the textile printing and dyeing industry, lithium bromide can be used as a humidity regulator to control workshop humidity and ensure the uniformity of dyeing of printed and dyed fabrics; In the metallurgical industry, lithium bromide aqueous solution can be used for metal surface treatment, playing a role in rust removal and corrosion inhibition; In addition, it can also be used for special cooling systems in the aerospace industry to meet the temperature control requirements in extreme environments.
