Fault Detection and Diagnosis (FDD) Using Nonlinear Regression Models for Heat Exchanger Faults in Heat Pump System

Transactions of the Korean Society of Mechanical Engineers B, 2011
Key Words: Heat Pump(히트펌프), Fault(고장), Detection(감지), Diagnosis(진단), Heat Exchanger(열교환기)초록: 본연구에서는비선형회귀모델을이용한히트펌프시스템에서의고장감지및진단알고리즘을개발하였다. 히트펌프시스템에발생할수있는다양한고장요소중, 열교환기고장에대한연구를수행하였다. 해석식을바탕으로제작한모델을이용하여총4가지작동모드(무고장, 증발기고장, 응축기고장, 응축기와증발기고장)에대한시뮬레이션을수행하였다.

Important sensors for chiller fault detection and diagnosis (FDD) from the perspective of feature selection and machine learning

International Journal of Refrigeration, 2011
Abstract The benefits of applying automated fault detection and diagnosis (AFDD) to chillers include less expensive repairs, timely maintenance, and shorter downtimes. This study employs feature selection (FS) techniques, such as mutual-information-based filter and genetic-algorithm-based wrapper, to help search for the important sensors in data ...
