A Fault Diagnosis Model and its Application in Chiller Operating

Abstract:

The chiller performance decrease with the system operating is inevitable, however, determining how to predict when it will happen, and how to identity the degree of performance decline, it is very important to solve these actual problems for chiller high efficiency operating and daily management. This paper developed a fault diagnosis model based on thermodynamic analysis of chiller’s refrigeration cycle and heat transfer analysis of its heat exchangers, taking three projects which involve different source sinks, namely, air source, ground source and reclaimed water source as cases study, described the fault diagnosis method and implementation steps through these engineering cases, the results show that the fault diagnosis model provides a newly simple and effective approach for chiller operation monitoring.
