Plants not only enhance the aesthetic appeal of indoor spaces, but also contribute to the regulation of the indoor thermal environment. In this study, an active plant wall (APW) integrated with air-conditioning system to investigate its influence on the indoor thermal conditions, as well as examine participants' skin temperature and subjective perceptions. In transition season and winter, the results demonstrated that APW led to a decrease in indoor temperature by 1.35℃ and 1.03℃, respectively. The mean relative humidity (RH) enlarged by 11.6% and 20.76%. In summer, APW caused a rise of 0.18℃ in indoor temperature and led to a decline of 2.7% in RH. Throughout the year, APW controlled air speed at 0.2-0.3 m/s, reducing the CO concentration by 42.35ppm, 43.83ppm and 46.83ppm, respectively. APW brought the mean skin temperature (MST) in Room B closer to neutral skin temperature of 33.2℃ throughout the year. Additionally, APW raised overall air fresh and thermal comfortable levels throughout the year to around "Fresh (+ 1)" and "Slightly comfortable (+ 1)", respectively. The findings suggested that APW can enhance indoor air quality and thermal comfortable levels throughout the year.
植物不仅能提升室内空间的美学吸引力,还有助于调节室内热环境。在本研究中,一个与空调系统集成的主动式植物墙(APW)被用于研究其对室内热状况的影响,并检测参与者的皮肤温度和主观感受。在过渡季节和冬季,结果表明主动式植物墙分别使室内温度降低了1.35℃和1.03℃。平均相对湿度(RH)分别增加了11.6%和20.76%。在夏季,主动式植物墙使室内温度升高了0.18℃,相对湿度下降了2.7%。全年中,主动式植物墙将风速控制在0.2 - 0.3米/秒,分别使一氧化碳浓度降低了42.35ppm、43.83ppm和46.83ppm。主动式植物墙使B房间的平均皮肤温度(MST)全年更接近33.2℃的中性皮肤温度。此外,主动式植物墙全年将整体空气清新度和热舒适度分别提高到了“清新(+1)”和“稍舒适(+1)”左右。研究结果表明,主动式植物墙全年都能提高室内空气质量和热舒适度。
