户间传热是集中供暖热计量中的一个技术难题。目前我国采取的解决办法是将系统总供热量中的一部分按各户建筑面积进行分摊 ,这部分热量占系统总供热量的百分数称为面积分摊百分数。对面积分摊百分数的影响因素进行了计算分析和灵敏度分析 ,认为户型、室内平均温度、换气次数对面积分摊百分数的影响较大 ,较为合理的数值范围是 3 0 %～ 45 %。
Household heat transfer is a technical problem of heat metering in central heating. At present, our solution is to share part of the total system heat supply by the construction area of each household. The percentage of the total heat of the part of the total heat supply of the system is called the percentage of area distribution. The influencing factors of the percentage of area apportionment are analyzed and the sensitivity analysis is carried out. It is considered that the influence of size, indoor average temperature and ventilating frequency on the percentage of area apportionment is larger, and the more reasonable range is 30% ~ 45%.
