Title:
吸収冷凍機の性能診断システム
Document Type and Number:
Japanese Patent JP7022658
Kind Code:
B2
Abstract:
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
