中西部一家油漆和涂料制造商的研究中心的一个翼楼的通风柜使用情况是通过在每个通风柜前面附上一份简单的调查表来测量的。在一个月的时间里，通风柜用户记录他们开始在通风柜内工作的时间、大致的窗扇高度、在通风柜内执行的程序以及离开通风柜的时间。此外，“备注”栏允许用户注意发动机罩的任何异常情况。对56个通风柜进行了评估。这些数据相互关联，以显示以下内容:给定一天的平均空气流量、一天中给定时间的平均空气流量、峰值空气流量使用量，以及发动机罩使用者的显著行为模式。虽然概念简单，但该程序将为该研究中心计划的排气系统设计提供基础。 关键词:测量、排气罩、工业、实验室、涂料行业、人员、空气流量、空气流量、行为、研究。引用:研讨会，ASHRAE Trans。，1993年，第99卷，第2部分，论文编号DE-93-1-1429-439，图7，表2，参考文献。

Fume hood use in one wing of the research centre of a Midwest-based paints and coatings manufacturer was measured using a simple survey form attached to the front of each fume hood. For a period of one month, fume hood users logged the time they began work in the hood, the approximate sash height, the procedure performed in the hood, and the time of departure from the hood. In addition, a "remarks" column allowed the user to note any unusual conditions at the hood. Fifty-six fume hoods were evaluated. The data were correlated to show the following - mean air flows for a given day, mean air flows at given times during a day, peak air flow use, and significant behaviour patterns of hood users. Though simple in concept, this procedure will provide a basis for the design of planned exhaust systems at this research centre.KEYWORDS: measuring, exhaust hoods, industrial, laboratories, paints industry, personnel, air flow rate, air flow, behaviour, research.
