ABSTRACT:
A corrosion inhibiting working fluid for absorption refrigeration systems and a method of manufacturing such a fluid. The fluid is an aqueous solution of a halogen salt of lithium or ammonia to which are added water soluble compounds containing molybdates, borates and, in a preferred embodiment, silicates. Preferred concentrations of the resultant molybdenum, boron and silicon ions are disclosed. A water soluble compound containing a hydroxide is also added to produce an alkaline normality. In a preferred method of manufacture, the additive compounds are added to the working fluid as aqueous solutions.
