摘要
室内空气中常见的污染物有二氧化碳(CO2)、颗粒物(PM)和挥发性有机化合物(VOC)三大类。除了通风稀释污染物的方法外,目前应对PM和VOC类的污染物已有多种实用的过滤和吸收方法,而CO2浓度高的问题仍然难以解决。垂直农业引入建筑是生态化设计的最新方向之一,利用植物光合作用对二氧化碳(CO2)进行吸收,并释放氧气。办公建筑由于其空间形式、工作时段等特性,特别适合集成垂直农业。本文侧重研究了办公室在门窗关闭时,垂直农业对室内CO2浓度的影响。对垂直农业和室内CO2浓度等相关参数进行了测量,并对取得的数据进行了计算和分析。研究发现,垂直农业有效降低了室内CO2浓度,构建了人和植物共生的微环境。垂直农业若能与其他空气过滤和净化方法配合使用,则能有效提升室内空气质量,降低新风需求量,也就间接降低了建筑能耗。
Carbon dioxide (CO2),particulate matter (PM) and volatile organic compounds (VOC) are common pollutants in indoor air. Apart from ventilation and dilution,there are currently many practical filtration and absorption methods for PM and VOC pollutants. However, the problem of high CO2 concentration remains unsolved. The introduction of vertical farming into buildings is one of the latest development of ecological design.Plant photosynthesis is used to absorb CO2 and generate oxygen. Office buildings are particularly suitable for integrating vertical agriculture due to their spatial form and working hours. This paper focused on the effects of vertical agriculture on indoor CO2 concentration when the doors and windows of the office are closed. Related parameters were measured,and the obtained data were calculated and analyzed. The results show that vertical farming effectively reduces indoor CO2 concentration and builds a symbiosis between the occupants and plants. If used together with other air filtration and purification methods,vertical farming can effectively improve indoor air quality,reduce the demand for fresh air,and indirectly reduce building energy consumption.
