          摘要:

          我国北方大量既有单管供暖系统分户热计量的改造成本很高。根据多年的实践经验,对原有单管供暖系统的结构进行了简单的改造。改造后的系统在一定条件下用户调节室内温度对系统流量的影响很小,可视为定流量系统,从而可用流量系数分配法代替流量计量。采用该方法可节约大量的改造成本。

          Abstract:

          The cost of household-based heat metering reconstruct is very high for existing single-pipe heating systems in northern part of China. Based on the practical experience for many years, performs simpler reforms of the conformation of original single-pipe heating system. The temperature adjustment of the reformed system under certain conditions has little effects on the flow of the system, so the system can be considered as a constant flow system and can be metered with flow-coefficient distribution method replacing flow metering method. Reform expenditure can be notably saved by using this method.
