某研发中心实验室空调通风系统案例分析与讨论

Case study of HVAC systems used in laboratories of a research and development center

介绍了该研发中心化学实验室的空调与通风系统及其控制方案设计;通过对该实验室空调与通风系统的测试与评估,发现部分排风柜的排风量不足、变风量(VAV)末端装置未调试整定、部分区域噪声过大等问题,并对引起这些问题的原因进行了分析;根据案例分析,总结了实验室空调通风系统选择、调试、运行维护等应针对具体实验室特点重点考虑的因素,强调了系统调试对保证实验室空调通风系统正常运行的重要性。

Presents the HVAC system and its control scheme used in the chemical laboratory in this center. Testing and assessing the system, finds that the exhaust air rate from partial fume hoods is insufficient, the variable air volume terminal devices are not adjusted, and noise is higher in part zones. Analyses the causes resulting in these issues. According to the case study, summarizes the factors which should mainly be considered when selecting, commissioning, operating, maintaining the system. Emphasizes the importance of system commissioning on the normal operation of HVAC system in the laboratory.
