Which statement about lithium bromide used in absorption systems is false?

Lithium bromide is a key component in absorption refrigeration systems, functioning primarily as an absorbent for water vapor. In this context, the reason the statement about it being non-corrosive is incorrect relates to its chemical properties. Lithium bromide has hygroscopic characteristics, meaning it attracts and retains water vapor from the atmosphere, which sets up conditions for potential corrosion, especially in the presence of moisture and other contaminants.

Furthermore, lithium bromide does participate actively in the absorption cycle where it absorbs water, hence it is not correct to consider it non-corrosive when it can lead to issues in certain conditions.

The other characteristics of lithium bromide align with its behavior in these systems. It does indeed act as a refrigerant in that it facilitates heat transfer as part of the absorption cycle, and it is hygroscopic, a property that is essential for its operation. It can also be used in heating cycles when associated with certain types of systems, showing its versatility. Understanding these properties is crucial for the operation and maintenance of systems utilizing lithium bromide.
