摘要
分析了供暖居住建筑按换气次数法确定的空气渗透量与室内最小新风量标准的差异。随供暖期室外平均温度的降低和人均居住建筑面积的减少,空气渗透耗热量在建筑物耗热量中占较大的份额。认为节能标准应根据各地区的气候条件等因素有所差别,对于供暖期室外平均温度较低的地区,在有限提高围护结构保温性能的同时,应将空气热回收作为供暖居住建筑节能的重要措施。
Analyses the difference between the air infiltration volume determined by air changes method and the minimum outdoor air requirement for residential buildings. With the mean outdoor temperature decreasing during the heating period and per capita living area reducing, the proportion of the infiltration heat loss to the building heat consumption increases. Considers that related building energy efficiency standards should be modified depending on different climate conditions, and for the zones with lower mean outdoor air temperature during heating period and limited envelope insulation, air heat recovery should be used as a major energy saving measure.
