METHOD AND APPARATUS FOR DIAGNOSING CIRCULATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To easily economically provide a method and an apparatus for diagnosing circulation system by which the circulation system for deciding timing of preventive maintenance can be evaluated and the collection amount of data can be minimized.

SOLUTION: The method and the apparatus for deciding the service life of the circulation system comprises the process of deciding at least one characteristic of the system to decide a characteristic value and deciding a cycle time of the system. At least one system characteristic is applied to an algorithm in which the system characteristic is integrated to decide a diagnostic value, and comparing the obtained diagnostic value to a predetermined value to determine the performance status of the system. The apparatus includes a sensor for detecting the system characteristic and a calculating section operatively connected to the sensor. The calculating section including circuitry for performing an integration on the system characteristic to decide a diagnostic value and comparing the diagnostic value to a predetermined value to decide the operation status of the system.
