【摘要】 阐述了现行热负荷朝向修正率法存在一些缺陷 ,不适用于节能建筑的热负荷朝向修正计算 ,即使用于传统型围护结构的热负荷朝向修正计算 ,精度也较低 ,又指出了热负荷朝向修正值法也有一些不足。作者提出了新的采暖热负荷朝向修正计算方法 -采暖室外计算温度朝向修正值法 ,可用于各种墙体的热负荷朝向修正计算 ,并给出了全国各主要城市的采暖室外计算温度朝向修正值。还给出了窗的热负荷朝向修正值的修正系数 ,可解决严寒地区节能建筑采用三层窗的热负荷朝向修正计算需要。更多还原

【Abstract】 The current principle on heating-load orientation revision ratio has some defects,it is unfit for the calculating of heading load orientation revision in energy saving buildings.Even it is applied to a calculation of conventional exterior protecting construction,the accuracy is very low,and the principle on heating load orientation revision value has some deficiency.A new calculation principle of orientation revision was presented,which could be used to calculate orientation revision value of all kinds of walls,and the revision coefficient of that of windows.It can meet the requirement of calculation of heating load orientation revision of three ply windows.更多还原
