空调通风调控臭氧诱发体表化学污染有效度及协同送风量研究

空调通风调控臭氧诱发体表化学污染的"有效度"及"协同送风量"的确定方法属于室内空气品质研究领域一个亟待解决的重要科学问题。本项目将以O3诱发体表化学污染为对象对这一基础科学问题展开深入研究。采用理论分析、实验测试和仿真模拟相结合的方法，研究O3诱发体表化学反应的关键参数随影响因素的变化规律、体表源汇边界、源项处理方法，构建并验证O3诱发体表化学反应的物质转化与质量输运模型；分别从物质转化和质量输运角度建立空调通风系统控污有效度指标，形成判定空调通风系统调控O3诱发体表化学污染有效程度的科学方法；得到两类有效度指标之间的协同变化区间和协同送风量与基准送风量之间的相关性特征，建立协同送风量的确定方法并完成其应用验证。项目研究成果将在当前存在室外大气质量下降和空调通风系统自身污染这一背景前提下为判定空调通风系统控污能力提供重要理论依据，为同步调控直接散发污染和二次污染提供重要技术支撑和基础数据。

It's an important scientific problem needing to be solved deeply in indoor air quality research field that effectiveness of air conditioning and ventilation controlling human surface chemical pollution induced by ozone and method for determing synergistic supplied airflow rate. This project will carry out deep research on this fundamental scientific problem , regarding human surface chemical pollution induced by ozone as the analytical object. With theoretical analysis, experimental test and simulation, variation of the key parameters related with human surface chemical reaction induced by ozone with affecting factors, source and sink boundary, processing method of source term are studied. Component transformation and mass transport model of human surface chemical reaction induced by ozone is established and verified. Effectiveness indexes of air conditioning and ventilation system controlling pollution are put forward from aspects of component transformation and mass transport, respectively. Scientific method for judging effectiveness of air conditioning and ventilation system controlling human surface chemical pollution induced by ozone is formed. Synergistic variation range of these two kinds of effectiveness indexes and relevance characteristics between synergistic supplied airflow rate and reference airflow rate are obtained. Method for determing synergistic supplied airflow rate is established and its application verification is provided. Research achievement of this project will provide important theoretical basis for judging the performance of air conditioning and ventilation system controlling air pollution, under the premise that outdoor air quality decline and air conditioning and ventilation system pollution are existing currently. Moreover, it will provide important technical support and basic data for synchronous controlling direct emission pollution and secondary pollution.
