河南寒冷地区农村住宅墙体节能设计研究——以焦作市西南冷村农宅为例

Study on Energy-saving Design of Rural Residential Wall in Cold Region of Henan——Take Jiaozuo Southwest Cold Village as Example

运用DesignBuilder软件对焦作地区某农村居住建筑全年累计冷、热负荷、总负荷进行模拟,并计算其总负荷节能率。选取外墙系统节能的关进因素:基层墙体材料(A)、保温材料(B)、保温方式(C),利用正交试验方法研究了各个因素对建筑总负荷节能率的影响。研究结果表明焦作地区外墙保温材料对农宅全年总负荷节能率影响最大,即对建筑能耗影响最大,其次是基层墙体材料和保温方式,并得到了建筑总负荷节能率最大的优化组合方案。

This essay uses software DesignBuilder to simulate the annual accumulative cooling,heating ond total loads of a rural residential building in Jiaozuo and calculate its energy saving rate for total load.Selecting the key aspects of energy efficiency for the external wall system as base wall material(A),insulating materials(B)and simulation method(C),their influences to the buildings'total loads energy saving have been studied using orthogonal experiment.The research result shows that in Jiaozuo area,the external wall insulating material has the greatest effect to the onnual total load energy efficiency,in other words,biggest influe nee on buildings'energy consumption,followed by base wall materials ond insulation methods.The optimal portfolio has also been obtoined for the maximum energy saving to total building loads.
