基准室温的流量温度热分配方法的计量原理
Metering principle of a heat allocation method based on TFTM
摘要：
将建筑物作为一个整体进行热量分配时，分配仪表与建筑物或供暖系统构成了热量分配系统。提出了热分配系统需要满足的基本条件，分析了室内供暖系统的调节对带跨越管的单管顺序式系统流量分配的影响；认为当分配模型与供暖系统相关时，不能将各个用户的流量分配比例当作常量处理。作者提出的基准室温的流量温度热分配方法，可以消除供暖系统对分配原理的干扰，保证各个热用户热量分配的起点一致，分摊结果合理、准确。
Abstract：
Heat allocation meters and building or heating system constitute a heat allocation system when taking the building as a whole to allocate heat. Presents the basic requirements of the heat allocation system needed to meet and analyses the influence of regulating the indoor heating system on flow distribution of the single-pipe series-loop system with a cross-over pipe. Points out that the flow distribution proportion is not a constant when the allocation model is correlative with the heating system. The proposed heat allocation method based on temperature-flow-temperature method (TFTM) can eliminate interference of the heating system on the allocation principle and ensure that all users have the same base for heat allocation and achieve a reasonable and accurate heat allocation result.
