Real-time fault detection and condition monitoring system for chiller

Predictive maintenance and increase on equipment effectiveness could be carried out by the equipment condition monitoring system (ECMS). The designing procedures of ECMS from failure analysis, monitoring method, monitoring steps, to maintenance strategy are presented in this paper. The maintenance strategies could be divided into three kind of category and four level architectures. Six kinds of monitoring methods, such as chiller performance coefficient monitoring, element efficiency monitoring, performance monitoring, data limit monitoring, vibration monitoring and current signature monitoring, are also discussed in this paper
