PERFORMANCE EVALUATION METHOD AND DIAGNOSIS SYSTEM FOR ABSORPTION WATER CHILLER AND HEATER

摘要

PPROBLEM TO BE SOLVED: To provide a method for evaluating performance of an absorption water chiller and heater with a minimized number of measuring points, and a diagnosis system using it. PSOLUTION: A measuring means 2 measures a temperature or pressure within the absorption water chiller and heater, a simulator 3 calculates a cycle operating state of the absorption water chiller and heater, using an operation amount such as heat exchanger contamination factor as a parameter, and a weight function calculation part 14 calculates a weight function from the measurement result or the calculation result. A target function calculation part 15 calculates a weighted residual that is a target function from the measurement result, the weighting result and the weighting function, and an evaluation device 1 calculates the operation amount of the absorption water chiller and heater by minimizing the target function.
