Verification of the electronic model of the thermal network by "equivalent absolute roughness"
The article substantiated the need to create electronic models of heating systems using BIM and GIS technologies. It is indicated that the original model data is needed correctly. The theoretical basis for determining the specific drop in pressure in thermal networks is given and its functional dependence on the size of the equivalent absolute roughness of the pipeline walls is established. The dependence of the change in the equivalent absolute roughness on the life of the pipeline is given. References to literature containing the most complete base of values equivalent to absolute roughness are given. A combined hydrometric graph of the hydraulic heating system modes at different values of the equivalent absolute roughness is given. Recommendations for verification of the electronic model have been given.
