用CO_2作示踪气体在风工程中的应用

Carbon Dioxide Used as Tracer Gas in Air Engineering

用ＣＯ２为示踪气体代替常用的ＳＦ６，用于室内环境的有关风工程的科研、设计调研等，具有测试方法简便、标气源广价廉、便于推广等优点．文中介绍了用化学吸收法测试ＣＯ２的技术。用ＣＯ２为示踪气体用于科研的应用实例及该方法评价．

In the air engineering research of indoor environment, carbon dioxide can be used as tracer gas instead of the common SF6. Such replacement has advantages of the test simplity, eastness to obtain, low cost and convenience for popularization. This paper presents measuring technique of CO2 by means of chemiabsorption, examples of using CO2 as tracer gas in scientific research and the comment on this method.
