CALCULATION OF PREVENTION OF HEAT LOSSES IN HEATING SYSTEM PIPES.

This article examines methods for reducing heat losses in heat supply system pipelines and evaluates their technical and economic efficiency. The study compares the performance of an existing deteriorated insulation layer with a proposed 50 mm mineral wool insulation for an external DN100 main pipeline. The calculation results indicate that the proposed insulation reduces heat losses by 51.5%, providing seasonal savings of 17,800 kWh of useful thermal energy for a 100-meter pipeline section. The economic analysis demonstrates that the investment required for pipeline re-insulation can be recovered within approximately 1.5 heating seasons, confirming the feasibility of the proposed measure.
