摘要
建筑外墙设置保温层能减少外墙耗热量,从而降低污染物排放量。介绍了供暖期单位面积外墙年耗热量折合成的年燃料耗量及年CO2、SO2排放量的计算。结合实例,分析了外墙保温层厚度与年燃料耗量及年CO2、SO2排放量的关系。在以聚苯颗粒保温砂浆作为保温材料,分别采用3种燃料供热时,节能建筑比基础建筑的年燃料耗量及年CO2、SO2排放量的减小幅度为:对于天然气供热系统,年燃料耗量及年CO2排放量均减少52.2%,无SO2排出;对于燃煤供热系统,3项指标均减少5.5%;对于燃油供热系统,3项指标均减少56.9%。
The addition of insulating layer on external wall of a building can reduce the heat consumption of external wall to reduce pollutant emission. The calculation of annual fuel consumption and annual CO2 and SO2 emission converted from annual heat consumption per unit area of external wall in heating period is introduced. The relation between the thickness of insulating layer of external wall, annual fuel consumption and annual CO2 and SO2 emission is analyzed with an example. When EPS granule insulating mortar is used as insulating material, and three kinds of fuels are used for heating respectively, the reduction of annual fuel consumption and annual CO2 and SO2 emission of energy-saving building compared with basic building is that the annual fuel consumption and annual CO2 emission are reduced by 52.2% without SO2 emission for natural gas heating system; the three indexes are reduced by 5.5% respectively for coal-fired heating system; the three indexes are reduced by 56.9% respectively for oil-fired heating system.
