Uncertainty evaluation on some heat metering methods based on total heating load of whole building
摘要：
基于楼栋总供热量的热计量方法的热量分摊模型涉及多个测量参数，直接测量参数的误差直接影响分摊热量的不确定度。利用不确定度相关理论，分析了几种基于楼栋总供热量的热计量方法的不确定度分量的变化范围，对其不确定度进行了评价，并对如何减小热计量方法的测量不确定度提出了建议。

Abstract：
For the heat metering methods based on total heating load of the whole building, heat allocation models involve many measurement parameterss. The error of the direct measurement parameter directly influences the uncertainty of the heat allocation. Analyses the variation range of the uncertainty components of some heat metering methods based on total heating load of the whole building, and evaluates the uncertainty. Besides, proposes a way to reduce the measurement uncertainty of heat metering methods.
