Ventilation is central to human civilization. Without it, the indoor environment rapidly becomes uncomfortable or dangerous, but too much ventilation can be expensive. We spend much of our time indoors, where we are exposed to pollutants and can be infected by airborne diseases. Ventilation removes pollution and bioaerosols from indoor sources but also brings in pollution from outdoors. To determine an appropriate level of ventilation and an appropriate way of providing it, one must understand that the needs for ventilation extend beyond simple thermal comfort; the quality of indoor air is at least as important. An effective ventilation system will remove unwanted contaminants, whether generated within the space by activities or by the simple act of breathing, and ensure that the ventilation system does not itself introduce or spread contaminants from elsewhere. This review explores how ventilation flows in buildings influence personal exposure to indoor pollutants and the spread of airborne diseases.

建筑通风：个人暴露的后果


通风是人类文明的核心。没有它，室内环境很快就会变得不舒服或危险，但过多的通风可能会付出高昂的代价。我们大部分时间都在室内度过，在那里我们会接触到污染物并可能感染空气传播的疾病。通风可以去除室内污染和生物气溶胶，但也会带来室外污染。要确定适当的通风水平和提供通风的适当方式，必须了解通风需求超出了简单的热舒适;室内空气质量至少同样重要。有效的通风系统将去除不需要的污染物，无论是通过活动还是简单的呼吸行为在空间内产生，并确保通风系统本身不会从其他地方引入或传播污染物。本综述探讨了建筑物中的通风流如何影响个人暴露于室内污染物和空气传播疾病的传播。
