研究和开发加热、通风和空调（HVAC）系统的自动控制、自动故障检测和诊断的改进方法需要动态仿真软件工具。这些工具必须生成数据，准确模拟仪表从HVAC系统和设备的无故障和故障动态运行中记录的实际数据。风机盘管机组（FCU）是一种简单、经济的设备，广泛应用于商业、机构和多户住宅的暖通空调系统中。然而，文献中很少有关于改进其设计和操作的报道。还缺乏针对FCU的动态模拟工具开发。本文开发了一个工具，用于模拟FCU在故障和故障情况下动态运行的数据- 免费条件。使用从实验室真实FCU中实验收集的数据，采用全面、系统的验证程序，在不同季节的故障和无故障运行条件下对工具进行验证。经过验证的工具不仅可以预测不同控制策略下的真实FCUBE行为，还可以预测与各种故障相关的症状，以及这些故障对系统性能和乘员舒适性的影响。引文:ASHRAE论文CD:2014 ASHRAE年会，华盛顿州西雅图

Dynamic simulation software tools are needed for the research and development of improved methods for automatic control and automated faultdetection and diagnosis of heating, ventilation, and air conditioning (HVAC) systems. These tools must generate data that accurately simulate thereal data that instruments would record from both fault-free and faulty dynamic operation of HVAC systems and equipment. Fan coil units(FCU) are simple, economical devices used extensively in the HVAC systems of commercial, institutional and multifamily residential buildings.However, very little has been reported in the literature to improve their design and operation. There has also been a lack of dynamic simulationtool development focusing on FCUs. The work here develops a tool to simulate data from FCUs operating dynamically under faulty and fault-freeconditions. A comprehensive and systematic validation procedure, using data collected experimentally from real FCUs in a laboratory, is used tovalidate the tool under both faulty and fault-free operating conditions in different seasons. The validated tool not only predicts real-world FCUbehavior under different control strategies, but it also predicts symptoms associated with various faults, as well as the effects those faults have onsystem performance and occupant comfort.
