通过对房间内有、无花卉时的二氧化碳浓度测定、比较、分析,结果显示,普通家庭的房间内摆放一盆花草对室内二氧化碳的浓度几乎不会产生影响,放3盆花草,5盆花草能有效降低白天室内二氧化碳的浓度,放5盆花草夜晚二氧化碳浓度达到轻度污染国际指标。另外,实验也证明,开窗通风是改善室内空气质量的非常有效的方法。
Through the analysis of the concentration of carbon dioxide in the room with and without flowers, the results showed that placing a pot of grass in an ordinary family room had little effect on the concentration of indoor carbon dioxide. Putting 3 pots of grass and 5 pots of grass Can effectively reduce the indoor concentration of carbon dioxide during the day, put 5 pots of grass to reach the night of carbon dioxide concentration of the international indicators of mild pollution. In addition, the experiment also proved that window ventilation is a very effective way to improve indoor air quality.
