description: The given work is devoted to developing a heat network plan inside communication tunnel in permafrost conditions located in Norilsk. The following goals were set within workâs volume: 1. Thermal load analysis and hydraulic network calculation. 2. Thermal expansion compensation determination. 3. Determining communication tunnelâs insulation thickness for preserving permafrost conditions. 4. Compiling technical specification and defining estimated cost of the project. The work is based on the Technical Assignment. Calculations were made to determine thermal loads in the district heat network and hydraulic losses present in it, thermal insulation of the pipelines and the required communication tunnel insolationâs thickness to preserve permafrost conditions with the use of Â«ANSYS FluentÂ»; thermal expansion, emerging inside pipeline network, the necessary air flow required for communication tunnel with the help of Â«Vent-CalcÂ», and finally, estimated cost of the project was defined according to similar projects.
