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

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%.
