例1:试求北京地区80住2-4住宅通用设计的建筑物耗热量指标及采暖耗煤量指标。已知该住宅为砖混结构,4个单元,6层楼,层高2.7m,南北朝向,单层钢窗,楼梯间不采暖。采暖期Z=126d/an,采暖期平均温度te= -1.6℃,采暖期度日数Dd_(di)=2470℃·d/an建筑面积A_o=32 58.8m~2,建筑体积V_o=8749.4m~3,外表面积F_o=2459.9m~2,体型系数S=F_o/V_o=0.281。换气体积V=0.60 V_o=52 49.6m~3。各部分围护结构的传热系数
Example 1: Try to calculate the heat consumption index of buildings and heating coal consumption in the general design of 2-4 residential buildings in Beijing. The house is known as a brick-concrete structure, 4 units, 6 floors, floor height 2.7m, north-south orientation, single-storey steel windows, stairwell heating. Heating period Z=126d/an, heating period average temperature te=-1.6°C, heating period days Dd_(di)=2470°C·d/an building area A_o=32 58.8m~2, building volume V_o=8749.4m~ 3, the external surface area F_o = 2459.9m ~ 2, the body size coefficient S = F_o/V_o = 0.281. The ventilation volume V=0.60 V_o=52 49.6m~3. Heat transfer coefficient of each part of enclosure structure
