To visually grasp an occurring phenomenon in which an absorption refrigeration machine changes in performance and then to perform proper conservation not only in rated operation, but also even in a case where a cooling load etc., are different from those in the rated operation.SOLUTION: A performance diagnostic system for absorption refrigeration machine that diagnoses performance of an absorption refrigeration machine having an evaporator, an absorber, a regenerator, and a condenser comprises: a calculation part which generates a Duhring chart of a no-problem state from data stored in a database and including at least solution concentration, and performs calculation for generating a Duhring chart in actual operation from data from a temperature sensor for cooling water fitted to at least the regenerator and a pressure sensor of the regenerator; and an output part which outputs the Duhring chart of the no-problem state and the Duhring chart in actual operation to a graph of the same scale.SELECTED DRAWING: Figure 3 【課題】吸収冷凍機について、定格運転時だけでなく、冷房負荷などが定格運転時と異なる場合であっても、性能が変化した場合に、生じている現象を視覚的に把握し、適切な保全を行う。【解決手段】蒸発器、吸収器、再生器及び凝縮器を有する吸収冷凍機の性能を診断する、吸収冷凍機の性能診断システムにおいて、データベースに格納された少なくとも溶液濃度を含むデータから無問題状態のデューリング線図を作成するための計算をし、少なくとも再生器に取り付けられた冷却水の温度センサ及び再生器の圧力センサからのデータにより実運転時のデューリング線図を作成するための計算を行う計算部と、無問題状態のデューリング線図と実運転時のデューリング線図とを同じスケールのグラフに出力するための出力部と、を備える。【選択図】図３
