自动故障检测和诊断（AFDD）是维护和提高建筑节能性能的有力工具。然而，AFDD技术的实施受到为AFDD应用开发的有限类型的建筑HVAC设备和系统的限制。包含各种常见HVAV设备和系统无故障和故障场景的综合数据集需求量很大。本研究进行了一系列受控实验室试验，旨在确定在仪表良好、受监控和受控的操作环境中，常见暖通空调设备和系统的无故障和故障性能。 测试了三种不同的HVAC系统，即风机盘管系统、双管道VAV系统和风机驱动VAV系统。本文着重介绍了双风道变风量空调系统的试验方法、主要结果和分析。双管道VAV系统分三个季节进行测试:夏季、冬季和秋季作为过渡季节，每个季节大约测试20个故障案例。实施的故障类型包括设备故障、传感器故障、执行器故障和控制故障。这些故障涵盖了典型双风道VAV系统中可能出现的大多数问题。断层间数据模式的初步比较- 文中还讨论了自由和错误情况。引用:ASHRAE论文:2015年ASHRAE年会，佐治亚州亚特兰大

Automated fault detection and diagnostics (AFDD) serves as a powerful tool to maintain and enhance building energy performance. However, the implementation of AFDD techniques is restricted by the limited types of building HVAC equipment and systems developed for AFDD applications. Comprehensive data sets containing a variety of fault-free and faulty scenarios of common HVAV equipment and systems are in high demand. This study conducts a series of controlled laboratory tests designed to determine both fault-free and faulty performance of common HVAC equipment and systems in a well instrumented, monitored, and controlled operating environment. Three different HVAC systems are tested, namely, fan coil unit system, dual-duct VAV system, and fan-powered VAV system. This paper focuses on the dual-duct VAV system test, and presents the test approach, major results, and analysis. The dual-duct VAV system is tested in three seasons: summer, winter, and fall as the transition season and approximately 20 faulty cases are tested in each season. The fault types implemented include equipment faults, sensor faults, actuator faults and control faults. These faults cover the majority problems that could occur in a typical dual-duct VAV system. Preliminary comparison of the data patterns between fault-free and faulty cases are also discussed in the paper.
