摘　　要：分户热计量作为建筑节能的一部分,目前,在国内新建建筑中已经大力的推广。我国北方存在的大量的老旧小区双管供热系统需要通过改造、加装热分户计量系统,传统的分户热计量的改造成本很高。根据实践经验论证在保持原有双管结构的基础上进行简单改造,以定流量替代流量计进行流量分配,节约了改造和检测成本,具有良好的应用价值。As part of energy efficiency technology, household heat metering has been vigorously promoted for new buildings in China. The cost of reconstruct for double-pipe heating system is very high in north of China. The paper proves that flowmeter can be replaced by flow-coefficient distribution method according to the practical experience, the cost of the modification and testing can been saved. It is very valuable for application.
