摘要
中央空调系统是商业建筑的能耗大户,对中央空调系统的监控有利于掌握系统是否正常运行。当系统不能正常运行时,及时对系统进行诊断,并找出问题所在并提出解决问题的办法;即使系统正常运行,及时对系统的各种指标进行评估以判断系统是否在高能效下运行。因此对建筑空调系统进行各种故障的检测及诊断对保证系统的正常运行,提高系统能效及保证室内环境有重要意义。本文回顾了建筑空调系统故障诊断的研究情况及进展,同时指出这方面的研究应该加强各种诊断策略及方法在实际工程应用方面的研究。
Centralized air-conditioning （A/C） systems take a large proportion of total energy consumption in commercial buildings. Monitoring is very important for the proper operation of A/C systems. When a system does not operate as intended, this system should be diagnosed to locate where the fault is and what measures should be taken to fix this problem. Even if the system operates normally, the system also should be assessed continuously to verify if this system is energy-efficient or not. Therefore, fault detection and diagnosis, and also assessment are significantly essential to ensure proper operation, improve energy efficiency and indoor air quality. The development of fault detection and diagnosis of HVAC systems was reviewed in this paper. Additionally, it is pointed out that the research should be mainly focused on the practical applications of the existing methods and strategies of fault detection and diagnosis in building A/C systems.
