Simulation and optimization of the district heating network in Scharnhauser Park

Abstract

The programme spHeat presented in this paper is designed for the hydraulic and thermal simulation of meshed pipes networks. It calculates the operating parameters of the system with hourly time steps and provides monthly and annual balances of heat load and supply. Entities like supply and return temperature, flow rate, heat losses and pump energy are calculated and compared for different operating scenarios. The biomass ORC power plant efficiency is also evaluated depending on the investigated load situation. Solar energy supply in the network of Scharnhauser Park in the South of Germany is analysed under local climate conditions.
