绵阳某高校化学实验楼既有通风系统效果实测研究

Research on the Existing Ventilation System of an University Chemistry Lab in Mianyang

通过对绵阳某化学实验楼的通风系统进行实测研究,指出现有系统所存在的相关问题。选取两个典型的通风系统为测试对象,当系统运行稳定时,监测室内通风柜排风口、顶部排风口以及桌面排风口三处风口风速。通过实测结果分析通风系统实际运行工况与设计工况的差别,评价既有通风系统存在的问题,并针对化学实验室通风系统的设计和运行提出建议。

The related problems of the ventilation system are put forward by the experimental study on a chemical experiment building in Mianyang city. This paper select two typical ventilation systems as the research subjects, and monitor the laboratory outlet （such as the top floor, desktop, and the fume hoods） velocity when system runs stably. Comparing the ventilation system difference between actual operation conditions and design conditions though the analysis of the test results, evaluating the problems in existing ventilation system, and putting forward suggestions on the design and operating of the ventilation system.
