A refrigerant/absorbent composition is disclosed which comprises an aqueous solution of at least one lithium halide, at least one zinc halide, and a corrosion inhibiting amount of thiocyanate ion. Also, a method of inhibiting corrosion of the metallic parts of an absorption heat transfer machine by adding a thiocyanate compound to a refrigerant/absorbent composition is disclosed. Further disclosed is a triple-effect absorption heat transfer machine having a working fluid in contact with metallic parts, said working fluid comprising a corrosion inhibiting amount of at least one thiocyanate salt.
