【摘要】：为确切了解夏季屋顶架空绿藤棚对南方民宅室内外热环境的防热效果,本文以厦门兑山村的典型民宅为研究对象在2014年8月9日~10日进行实测研究,对比包括"遮蔽房和无遮蔽房的空气温度、相对湿度、黑球温度、风速、顶棚表面温度、室内热舒适PMV值、屋顶地表温度、屋顶室外热舒适SET值",实验结果遮蔽房的室内PMV平均值为2.08,比无遮蔽房低0.84,尤其是20:30~次日10:30能提供14 h左右的PMV值1.3~2.0相对好的热舒适环境,午后室内PMV值下降相对无遮蔽房更明显且快速。绿藤棚灰空间的WBGT值低于32℃且显著低于露台,绿藤棚灰空间的SET值白天在30~35℃感受稍热,明显低于露台区域的30~38.55℃。结论证明绿藤棚的防热效果对于屋顶空间及遮蔽房都有明显作用,辅助降低空调能耗。
[Abstract]:In order to understand exactly the thermal protection effect of green vines roof on the indoor and outdoor thermal environment of southern residential houses in summer, this paper takes the typical residential houses in Twe Shan Village, Xiamen, as the research object, and carries out a practical study from August 9 to 10, 2014. The comparisons include "Air temperature, relative humidity, black ball temperature, wind speed, ceiling surface temperature, indoor thermal comfort PMV value, roof surface temperature," The average indoor PMV of the shelter room is 2.08, which is 0.84 lower than that of the unsheltered room. Especially, 20: 30 ~ 10:30 can provide about 14 h PMV 1.3 and 2.0 relatively good thermal comfort environment. The decrease of PMV in the afternoon room was more obvious and faster than that in the shaded room. The WBGT value of green rattan shed ash space was lower than 32 鈩，
