北京地区采暖冷风渗透耗热量计算方法的分析——《北京市建筑设计技术细则》中有关规定介绍

Analysis of calculating methods for infiltration heat loss in Beijing area——an introduction of Technology detailed rules of Beijing architectural design

对相关文献中采暖冷风渗透耗热量的两种确定方法进行了介绍和对比,认为按换气次数估算的方法与实际工程计算结果差距较大,不建议采用。提出了人员长期停留房间应按卫生要求的新风量校核房间换气量的观点,并通过实际工程对换气法和缝隙法计算结果进行了对比,分析其对能耗的影响,确定了一般住宅或类似建筑采暖冷风渗透耗热量的简单计算方法。

Describes and analyses the two methods for determining the infiltration heat loss from related literatures, Considers that the estimating result of air change method is much larger than that calculated by slot method and should not be adopted, Holds that the room ventilation rate should be checked by human＇s health requirements for fresh air quantity in a continued occupied room, contrasts the results of air change method and slot method through actual projects and analyses their impact on energy consumption. Determines the simple design procedure of infiltration heat loss for general residences or similar buildings.
