Uncertainty evaluation on some heat metering methods based on total heating load of whole building

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.
