西北乡村民居被动式太阳能设计实践与实测分析

Practice and Real Testing Analysis of Rural House Passive Solar Design in Northwest China

为改善西北乡村地区冬季居住热环境,降低冬季采暖能耗,结合当地太阳能资源富集特点与技术经济条件,提出适宜性被动式太阳能利用方案,并在银川市碱富桥村进行了工程实践。通过实验测试以及与传统乡村民居做比较,并利用室内主观舒适温度计算对新建民居冬季室内环境进行分析,测试与计算结果表明新建民居保温节能效果显著,验证了西北乡村地区被动式太阳能技术的可行性与有效性。

In order to improve the living thermal environment and decrease energy consumption of rural area in Northwest China in winter,this paper combine the characteristics of plenty of solar energy with local technology and economic condition,suggests an appropriate strategy for utilizing passive solar energy,and also puts into project practice in Jianfuqiao village in Yinchuan.A comparative analysis is made with the traditional vernacular through the experiments and tests.Also,the indoor objective appropriate temperature is used to calculate and analyze the indoor environment of newly-built rural houses in winter.The results from the tests and calculation indicate that there is a remarkable effect of heat preservation and energy saving in the newly-built houses.Accordingly,the availability and feasibility of solar passive technology in the rural area has been test and proved.
