摘要:

为改善哈尔滨居住建筑节能效果,以提高南向窗夏季遮阳效率为研究目的,根据哈尔滨气候特点来确定合适的窗地面积比,通过控制南向窗开设面积、高度与宽度、外墙厚度、遮阳板宽度等要素,在不降低冬季采光效果的前提下实现对夏季高温时段直射太阳光线的遮挡,减少室温制冷成本,提高居住建筑节能效率．经过仿真模拟分析,实现哈尔滨居住建筑南向窗节能效率最大化,通过一系列公式形成南向窗节能规范性设计模式,通过对地面接收热量的定量计算验证了节能南向窗的节能效果．

Abstract:

In order to improve energy saving efficiency of Harbin residential building, we select optimizing southern windows’ size to improve sunshade efficiency as research purpose, appropriate glazing floor area ratio of should be confirmed within the specification limitation according to Harbin’s climate. By controlling the southern windows’ area, height and width, wall thickness and visor width, energy saving efficiency can be improved by preventing direct solar insolation in summer, which can reduce the cost of room temperature refrigeration, without reducing solar insolation in winter. The energy-saving efficiency will be maximized by software simulation analysis, and the southern window normative design patterns is formed. Through calculating receiving heat of ground energy saving effect of the optimized southern window can be verified.
