为了解工作环境新风量供给情况。于2007至2008年选取6个发电及电力企业、6个电子企业、3个机械企业、5个轻工企业以及其他行业4个企业共计124个生产车间、控制室和50个办公室,采用ALNOR风量计(美国IST公司)测定新风量并对相应环境中的工作人员进行5%的随机抽样,以问卷调查法了解63名生产车间工作人员和68名办公环境工作人员主观感觉。结果显示,生产环境和办公环境新风量达标率分别为97.8%和42%。办公环境工作人员主观不适百分率(1.5%～27.9%)高于生产环境(0%～4.8%)。提示办公环境新风量供给应引起足够重视。
In order to understand the work environment fresh air supply. From 2007 to 2008, we selected a total of 124 production workshops, control rooms and 50 offices in 6 power generation and power enterprises, 6 electronic enterprises, 3 machinery enterprises, 5 light industry enterprises and 4 other industries, adopting ALNOR air volume (IST, USA) to determine the fresh air volume and 5% of the staff in the corresponding environment were randomly sampled. The survey method was used to understand the subjective feelings of 63 production workshop workers and 68 office workers. The results show that the compliance rate of new air volume in production environment and office environment is 97.8% and 42% respectively. The percentage of subjective discomfort in working environment staff (1.5% ~ 27.9%) is higher than the production environment (0% ~ 4.8%). Prompted fresh air supply office environment should be given sufficient attention.
