公共建筑空调通风系统应对雾霾天气的过滤措施探讨
Discussion on filtering measures to smog for air conditioning and ventilation systems in public buildings
摘要：
对当前国内应对雾霾天气所推出的有关通风系统空气过滤装置的一些设计选型方法的可行性提出了质疑。讨论了这些方法难于付诸实施的多方面原因。参考Eurovent 4/23-2018指南《一般通风中按EN ISO 16890评级的空气过滤器之选用》，根据国内情况提出了一种便于设计及工程管理人员使用的简明方法，并对该方法的实用性、可行性进行了讨论。

Abstract：
Questions the feasibility of current designing and selection method of air filter devices for ventilation systems in dealing with the haze weather. Discusses the multiple reasons of the infeasibility. Depending on the domestic situation, in reference to the Eurovent 4/23-2018 Selection of EN ISO 16890 rated air filter classes for general ventilation applications, proposes a concise method for designers and project managers, and discusses the practicability and feasibility of the method.
