夏热冬冷地区围护结构热工性能节能分析

Energy Saving Analyses on Envelope Thermal Properties in Hot Summer and Cold Winter Region

选取夏热冬冷地区7个典型城市住宅为研究对象,建立了一个6层居住建筑模型,利用能耗模拟软件VisualDOE4.0,分析了屋面、窗户、遮阳及外墙围护结构各部件热工性能对建筑能耗的影响.通过正交试验进行综合节能措施方案设计,分析不同围护结构组合方案的建筑能耗及节能率变化,最终确定优化组合方案,超过建筑节能25%的目标.模拟计算结果与实测结果吻合得很好,充分验证了模拟计算的正确性.

Residential buildings were selected as the research object in the seven typical cities of hot-summer and cold-winter region.The model of six-storey residential building was set up.Firstly,the effect of thermal properties of enclosure each component on energy consumption of residential buildings was analyzed by energy consumption software VisualDOE 4.0.Enclosures include roof,window,sunshade and exterior wall,et,al.Secondly,comprehensive measures schemes of energy saving were designed by the orthogonal experiment.Then,the building energy consumption and energy efficiency rates of different enclosures combination schemes were compared and analyzed.Finally,the optimize combination scheme is determined,exceeding the goal of enclosures saving 25% of energy.Simulation results are accordant with the experimental results.It is fully verified the correctness of the simulation calculations.
