居住建筑基准室温散热器热分配法的计量原理与实测分析

Metering principle and measurement analysis of radiator heat distribution method based on reference indoor temperature for residential buildings

该方法将热量计量与消除建筑物固有特性相结合,消除了同一栋建筑物内用户散热器型号不同、安装使用条件不同、散热器数量与设计值存在较大差别、水力失调及热力失调对计量结果的影响。详细介绍了热量分摊模型。为验证模型的合理性,以哈尔滨市某居民楼为例,对基准室温散热器热分配法、户用热量表法和温度面积法的测算结果进行了比较。结果显示,热量表法计量的每户热量值波动较大,而其他两种方法的每户热费一致性较好,最大差值为4.13%。

The method combines heat metering with elimination of building inherent characteristics, and removes the influences that result from different radiator types of heat users, different installation and using conditions, the difference of radiator number between design and installation value, and the difference of hydraulic condition and thermal condition between design and operation condition. Presents the heat allocation model in detail. To verify the rationality of the model, takes a residential building as example, compares the measuring results by radiator heat distribution method, household heat meter method and temperature-area method. The results show that the fluctuation of heat consumption among different households is larger for the household heat meter method, and the heat consumption by the other two methods are in good agreement with the maximal deviation of 4.13%.
