摘要
为了解南方民宅屋顶自发搭建的黑色遮阳网对室内外热环境的防热效果,以两个典型民宅为研究对象对其进行实测研究,一个是厦门集美兑山村民宅,另一个是厦港片区民宅为研究对象,在晴热天气测试其室内外气候参数,对比包括遮蔽房和无遮蔽房的空气温度、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,结果表明黑色遮阳网对室内的遮蔽房具有明显的防热效果,白天及其他大部分时间遮蔽房比无遮蔽房的空气温度、黑球温度、顶棚表面温度、室内PMV值都明显较低,并且下午随着日照减弱各个指标的降温也更快、幅度更大、显著缩短高温的持续时间;证实黑色遮阳网的防热效果对于屋顶灰空间作用不明显,却对于灰空间下方的遮蔽房间有明显作用。
In order to know the ecological impact of black sunshade net at roof,two measurements of civilian residence in Duishan village and in Xiamen harbor area are analyzed,by measuring indoor and outdoor climatic parameters and comparison of thermal comfort indexes in the sunny hot weather,including the air temperature,air humidity,black globe temperature,air velocity,ground surface temperature,surface temperature of ceiling and roof floor,PMV value of indoor area,SET value of outdoor area.The result shows that the black sunshade net has obvious heat shielding effect to the sheltered room,the At,Tg,ceiling and PMV of the sheltered room are much lower than that of unsheltered room in daytime and other most time,as well as the above-mentioned index drop down rapidly as the sunshine recede,and shorten the time of high temperature duration.It is verified that the attachment of black sunshade net at roof of civilian residence can remarkably improve the thermal comfort of interior room on the next floor sheltered by the black sunshade net,yet it has minor effect to improve the grey space at roof.
