Résumé

This article summarizes the operating principles of a lithium-bromide based absorption refrigeration plant and illustrates diagrammatically the operation of a two-stage absorption chiller. It explains the mechanisms by which absorbers deteriorate, the article lists chemical additives to the lithium bromide charge used in an attempt to control internal corrosion and points out that without proper and continuous monitoring of the LiBr's chemistry, the additives can actually do more harm than good. The author discusses what is involved in the restoration of an old absorption chiller, and recommends controlling the LiBr corrosion, cleaning up debris and repairing any mechanical damage. A table lists in a table analytical tests for absorption chillers.
