Technical Building Services Planning for Expansion and New Construction of District Heating Transfer Stations in Ludwigslust

Technical Building Services Planning for two new technical transfer points: a district heating transfer station at the TAV site and a transfer point in the Bauernallee heating plant. The heating plant has an existing generation and distribution structure with two biogas CHP units, two hot water boilers, and three network pumps, which will remain part of the future supply system. The TAV integration expands the existing heat supply and is implemented as an indirect hydraulic connection via heat exchangers. The transfer station at the TAV includes three parallel pumps, two heat exchangers (one redundant), and an outlet towards Grabow. The hydraulic design must be coordinated with the existing heating plant, with flow and return lines routed from the heating plant and integrated behind the three existing network pumps. Key parameters for the district heating connection include a thermal output of up to 8 MW, flow temperatures from 60 to 90 °C, return temperatures up to a maximum of 66 °C, and network pressure maintenance of at least 2.5 bar. For the TAV, a maximum thermal output of 8 MW is planned with an optimized combination of electricity production and district heating. The project will be processed through service phases 1 to 8, optionally LPH 9. Future integration of geothermal heat sources is planned.
