Designing Energy Efficient and Immune Buildings: Application of Advanced Air Purification System

通风系统的设计本质上是一种将室外空气引入室外，并将颗粒物、微生物和化学物质等污染物捕集和稀释，然后将其排放到室外的手段。ASHRAE通风标准明确承认了这些典型污染物，该标准要求通风率规格应基于居住者以及其他室内/室外污染源的贡献，这意味着需要增加通风率。增加通风率和新风量通常可以提高室内空气质量(IAQ)，但它们也会导致全球能源消耗的大幅增加。空气净化可以提供改善室内空气品质的关键策略，同时减少新风供应，同时节省能源。

Ventilation systems, by their very nature of design, are a means to bring in outdoor air and trap and dilute contaminants such as particulates, microorganisms and chemicals, and exhaust them to the outdoor. These typical contaminants have been recognized explicitly in the ASHRAE ventilation standard, which requires that the ventilation rate specifications be based on the contribution from occupants as well as other indoor/outdoor sources, implying that an increased ventilation rate is needed. Increased ventilation rates and outdoor air supply rates can generally enhance indoor air quality (IAQ); however, they can also result in a large increase of global energy consumption. Air purification can provide a key strategy to improving IAQ while reducing outdoor air supply with concomitant energy savings.
