Japanese Patent JP6940983
Kind Code:
B2
Abstract:
To identify a component causing a performance change when performance of an absorption type refrigerator is changed.SOLUTION: A performance diagnostic device for an absorption type refrigerator, includes: an efficiency calculation section for calculating efficiency of the absorption type refrigerator; a performance determination section for determining whether the efficiency of the absorption type refrigerator is normal; and an element diagnosis section for calculating performance of each component of the absorption type refrigerator. When the performance determination section determines that the efficiency of the absorption type refrigerator is deviated from a predetermined range, the element diagnosis section diagnoses a measurement value of an index of any one or more of the plurality of components of the absorption type refrigerator, and when the index of any of the measurement values is deviated from the predetermined range, determines that the component has an abnormality.SELECTED DRAWING: Figure 2
