重庆地区绿化屋顶与夜间通风联合作用的降温实验研究
Experimental study on green roof combined with night ventilation in Chongqing area
摘要：
在重庆地区搭建的2个实验箱中进行了绿化屋顶与夜间通风联合作用的隔热降温实验研究，引入室外低温空气通风，以弥补绿化屋顶在夜间会阻止室内热量向室外散发的不足。通过2个实验箱测量数据的对比分析发现，绿化屋顶与夜间通风结合后可显著降低室内温度和屋顶得热量。此外还对室内热环境的影响因素（室外气候参数、绿化屋顶土壤湿度）作了相关性分析。
Abstract：
Carries out a thermal insulation cooling experiment of green roof and night ventilation in two experimental boxes in Chongqing area. Offsets the insufficient indoor heat release due to the effect of green roof at night by low temperature outdoor air ventilating. Compares and analyses the measured data of the two experimental boxes. The results show that the combination of green roof and night ventilation can significantly reduce indoor air temperature and roof heat gain. Carries out the relativity analysis of indoor thermal environment influence factors such as outdoor environment conditions and soil moisture of green roof.
