Title:
フィルタのオンライン診断方法およびオンライン診断システム
Document Type and Number:
Japanese Patent JP7210820
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an online diagnostic method and an online diagnostic system of a filter capable of replacing the filter in proper replacement timing by clarifying the residual life of the filter.SOLUTION: An online diagnostic system includes: a measuring unit 4 outputting differential pressure data where the differential pressure of a filter 1 is measured by a differential pressure sensor, and temperature data and humidity data where temperature and humidity around the filter are respectively measured by a temperature sensor and a humidity sensor; a diagnostic unit 8 where timing that the differential pressure of the filter reaches a differential pressure upper limit value for management is predicted based on the respective measured data from the measuring unit 4 and the duration of the service of the filter; and a display unit 11 or a warning unit 12 displaying or warning the timing predicted by the diagnostic unit 8 as the replacement timing of the filter.SELECTED DRAWING: Figure 1
