Corrosion can be minimized in lithium bromide systems.
The lithium bromide-based absorption chiller has been around commercially since the late 1950s. It was introduced as a simple cooling system if there was already a source of steam available to concentrate diluted lithium bromide brine.
Under vacuum, water vapor flash boils at temperatures less than 100 [degrees] C. The boiling action provides a mechanism whereby heat can be removed from a chilled-water loop, which circulates through the chiller and building areas to be cooled.
But as the water vapor accumulates inside the chiller, the vacuum is soon lost. Hence, lithium bromide brine at 58% ...
