What are the special features of water and lithium bromide in absorption refrigeration?

Here are some special features of the water and lithium bromide in an absorption refrigeration system: 1) Lithium bromide has great affinity for water vapor, however, when the water-lithium bromide solution is formed, they are not completely soluble with each other under all the operating conditions of the absorption refrigeration system.

How does a water-lithium bromide vapor absorption refrigeration system work?

In a water-lithium bromide vapor absorption refrigeration system, water is used as the refrigerant while lithium bromide (Li Br) is used as the absorbent. In the absorber, the lithium bromide absorbs the water refrigerant, creating a solution of water and lithium bromide.

How long does a lithium bromide absorption machine last?

Lithium bromide absorption machines have been proven to have a life expectancy of approximately 20 years; afterwards significant corrosion can be observed. Performance of an absorption refrigeration systems is critically dependent on the chemical and thermodynamic properties of the working fluid.

Why is lithium bromide aqueous solution used in absorption heat pumps?

Modern systems maintains higher condensing pressure even when low-temperature condensing water is available to avoid crystallization. Lithium bromide aqueous solution is one of many other solutions widely used in the operation of the absorption heat pumps that are used for (heating and) cooling purposes.

How does a lithium bromide evaporator work?

In the absorber, the strong lithium bromide solution absorbed the water vapor leaving the evaporator to form a weak solution. The weak solution is then pumped into the generator and the process is repeated. Generally, the heat is removed from the system by a cooling tower. The cooling water passes through the absorber first then the condenser.

Which is better lithium bromide-water or ammonia-water cycle?

The results for Lithium bromide-water show that the cycles give better performance than the ammonia-water cycle. Solar cooling is an attractive idea because cooling loads and availability of solar radiation are approximately in phase.
