大中型商业建筑被动式过滤通风技术构想及分析

Study on the Technical Concept and Problem of Passive Filter Ventilation of Large and Medium-size Commercial Building

我国大中型商业建筑普遍存在能耗大、空气质量差的问题。为此,提出了被动式过滤通风系统基本构想,设想利用烟囱效应,在建筑中设置拔风系统,在墙上设置空气过滤网,为建筑提供充足的洁净新风。其后,分析了该系统的核心问题,并利用CFD软件对其进行了研究,理论证明了该系统的技术可行性。

The Large and medium-sized commercial buildings in our country have problems of large energy consumption,poor air quality.Therefore,this paper presents the basic idea about passive filtered ventilation system,conceived using the stack effect,set the wind pull system in the building and set up the air filter on the wall to provide adequate clean and fresh air for building.Then,analysis the core issues about this system,and researched by CFD software,theoretical proof the technical feasibility of this system.
