To provide a working medium for an absorption refrigerator that can highly inhibit corrosion of a structural material, and the absorption refrigerator using the same.SOLUTION: A working medium for an absorption refrigerator includes a propanol water solution as a refrigerant, and a corrosion inhibitor. The corrosion inhibitor includes one or more of an alkali metal salt, an alkaline-earth metal salt, and an oxyacid salt. The alkali metal salt is a hydroxide of an alkali metal, and the alkaline-earth metal salt is a hydroxide of an alkaline-earth metal.SELECTED DRAWING: Figure 2 【課題】構造材の腐食を高度に抑制可能な吸収式冷凍機用作動媒体およびこれを用いた吸収式冷凍機を提供する。【解決手段】吸収式冷凍機用作動媒体は、冷媒としてのプロパノール水溶液と、腐食抑制剤とを含む。腐食抑制剤は、アルカリ金属塩、アルカリ土類金属塩、および、酸素酸塩、のいずれか一つ以上を含む。アルカリ金属塩は、アルカリ金属の水酸化物であり、アルカリ土類金属塩は、アルカリ土類金属の水酸化物である。【選択図】図２
