ABSTRACT:
Anticorrosion solutions and processes useful for refrigeration processes are disclosed. Heteropoly complex anions of transitional metal elements can be added to an absorption refrigeration solutions which includes at least one alkali metal halide or similar compounds, or mixtures thereof, in combination with transition metal compounds or compounds of the metallic elements of Groups IIIa to VIa of the Periodic Table of Elements to minimize corrosion of the refrigeration system.
