摘要
使用便携式红外线气体分析仪对室内新风量进行测定研究,仪器型号为GHX-3010E,示踪气体选取二氧化碳(CO_2)。测定工作基于CO_2气体对红外线的选择性吸收及比尔定律进行。研究对象为一办公用房,分别使用平均法及回归方程法对其中的新风量进行测定,将所得数据处理后发现:两种方法测定结果相一致。本研究还讨论了示踪气体种类的选择及测定时在场人数对结果的影响等问题,并认为使用便携式红外线气体分析仪进行室内新风量的测定快速、准确,易于操作,具有很好的应用前景。
Indoor air change flow was determined by portable IR gas analyzer. The instrument was GHX - 3010E and the trace gas was carbon dioxide （ CO2 ）. Determination was based on the selective absorption of trace gas and Lambert Beer＇s Law. We chose an air - conditioned office, and carried out determination using 2 methods： average and multivariable linear regression equation. The results show that the 2 methods agree with each other very well. Research also discusses trace gas selection and personal influence on the determination. From the authors point of view, this method is rapid, accurate, and easy to operate, and haves good perspective in the future.
