Evaluating Fault Detection And Diagnostics Protocols Applied To Air-Cooled Vapor Compression Air-Conditioners, David P. Yuill, James E. Braun
Evaluating Fault Detection And Diagnostics Protocols Applied To Air-Cooled Vapor Compression Air-Conditioners, David P. Yuill, James E. Braun
David Yuill
Fault detection and diagnostics (FDD) tools are being increasingly applied in air-conditioning systems. There are many different protocols used in these FDD tools, so an important question to ask is: how well do the protocols work? This paper describes the ongoing development of the first standardized method of evaluation for FDD protocols applied to air-cooled vapor compression air-conditioning systems. The general approach is to feed a library of data – including temperatures, pressures, and humidity – to a candidate FDD protocol, and observe the responses of the protocol. The library includes data from units operating with no fault or with …
