针对变风量空调末端装置故障,提出了一种故障检测与诊断方法,并开发了故障检测与诊断软件。该软件使用累积和控制图检测空调末端装置故障,使用设计的基于规则的故障分类器寻找故障源。在线应用表明该故障检测与诊断软件十分可靠,有助于提高维护管理效率、室内热舒适性和空调系统能源效率。 Aiming at the failure of VAV air conditioner terminal device, a fault detection and diagnosis method is proposed and fault detection and diagnosis software is developed. The software uses accumulation and control charts to detect air conditioning end-device failures and uses a designed rule-based fault classifier to find the source of the fault. Online applications show that the fault detection and diagnostic software is very reliable and helps to improve maintenance management efficiency, indoor thermal comfort and energy efficiency of air conditioning systems.
