摘要
为了能有效诊断暖通空调系统（ＨＶＡＣ）中可能出现的故障，保证暖通空调系统安全、节能地运行，提出了一种应用于暖通空调系统故障诊断的新方法——故障向量空间法（ＦＤＳＭ）。ＦＤＳＭ 的基本思想是通过观察一组反映系统或设备结构特性的特征值的变化来进行故障诊断。该方法于１９９５ 年１０ 月在英国牛津接受了国际能源局第２５ 子课题（ｆａｕｌｔｄｅｔｅｃｔｉｏｎ ａｎｄ ｄｉａｇｎｏｓｉｓ ｉｎ ＨＶＡＣｓｙｓｔｅｍ ）主持的竞赛性检验，证明了这种方法的有效性和可靠性。这种方法的提出对ＨＶＡＣ系统的正常运行和节约系统能耗有较大的意义。
To detect and diagnose the faults in heating, ventilation and air conditioning (HVAC) systems effectively and operate the system safely and efficiently, a new method for fault detection and diagnosis (FDD) in HVAC systems, named fault direction space method (FDSM), was presented. The basic idea of this method was to detect faults by watching the characteristic parameter change that can be expressed by the structure of the system or component. The method passed the evaluation test that was organized by Annex 25 of International Energy Agency in Oxford in October 1995. The effectiveness and reliability of the method are satisfied. The method will be good for the operation of HVAC systems.
