ABSTRACT Temporarily enhanced natural ventilation of indoor environments can be achieved by opening windows and/or doors, i.e. airing. In this study, wind driven airing rate through doors was measured by tracer gas at a building model in a wind tunnel. Both single opening and cross flow airing was investigated, with doors placed in centrally on the long side of an elongated building model. It was found that cross flow airing yielded 4–20 times higher airing rate than single opening airing; lowest value occurring with opening surfaces perpendicular to wind direction. At single opening airing, windward positioned door yielded about 53% higher airing rate than leeward positioned. Inclusion of a draught lobby (extended entrance space) lowered airing rate by 27%, while higher wind turbulence increased it by 38%. Advection through turbulence appeared a more important airing mechanism than pumping. At cross flow, however, turbulence and draught lobby had practically no effect.

风驱动开门通风的风洞研究

摘要 通过打开窗户和/或门，即通风，可以暂时增强室内环境的自然通风。在这项研究中，通过风洞中的建筑模型中的示踪气体测量了风驱动通过门的通风率。研究了单开门和横流通风，门放置在细长建筑模型长边的中央。发现横流晾晒比单口晾晒的晾晒率高 4-20 倍；最低值出现在垂直于风向的开口表面。在单开通风时，迎风位置的门比背风位置的通风率高约 53%。包含通风大厅（扩展的入口空间）使通风率降低了 27%，而更高的风湍流将通风率提高了 38%。通过湍流的平流似乎是比泵送更重要的通风机制。然而，在横向流动时，湍流和气流大厅几乎没有影响。
