寒冷地区窗墙比对农宅能耗的影响分析

Influence of Window-wall Ratio on Energy Consumption of Rural Houses in Cold Regions

以山西农村住宅为研究对象,建立DeST-H模型,研究窗墙比的变化对寒冷地区冬季采暖热负荷的影响。结果表明,随着南向窗墙比的增加,太阳辐射进入房间的热量增加,建筑能耗降低。因此,适当增加南向窗墙比是既有农村住宅节能改造的有效措施之一。

Taking rural houses in Shanxi Province as the research object,this paper established the DeST-H model to study the influence of window-wall ratio on heating load in winter in cold regions.The results showed that with the increase of south-facing window-wall ratio,the heat of solar radiation entering the room increased and the building energy consumption decreased.Therefore,properly increasing the south-facing window-wall ratio is one of the effective measures for energy-saving reconstruction of rural houses.
