Economic benefits of fourth generation district heating

Energy, 2020
Abstract The main impetus for lower distribution temperatures in district heating systems is the lower heat supply costs obtained by these lower temperatures. In this paper, the differences in heat supply costs for two different temperature levels have been estimated for various future heat supply options. The estimations were obtained by modelling a

Optimal control of a fourth generation district heating network using an integrated non-linear model predictive controller

Applied Thermal Engineering, 2023
District heating (DH) can help increasing the share of renewable and residual energy sources in the heating sector. Usually a rule-based controller (RBC) is used for controlling these networks while more advanced control strategies like model predictive control (MPC) can support the transition to a decarbonised heating sector.

Specifying DHW heat demand profiles according to operational data: enhancing quality of a DH system model [PDF]

E3S Web of Conferences, 2021
For a DH network a meticulous analysis is required to detect a correlation of a reduction in energy demand from one year to another. The factors, which lead to such inconsistency, force an energy company (1) to modernize equipment at a consumer side and (

Method for Assessing Heat Loss in A District Heating Network with A Focus on the State of Insulation and Actual Demand for Useful Energy

Energies, 2020
The goal of this paper was to evaluate heat loss and the demand of district heating (DH) in the context of the fourth generation DH concept using a data-driven approach. The heat loss profile was calculated with GIS Zulu© (software (8.0.0.7539, Politerm,

District Heating of Buildings by Renewable Energy Using Thermochemical Heat Transmission

Energies, 2022
The decarbonisation of building heating in urban areas can be achieved by heat pumps connected to district heating networks. These could be ‘third-generation’ (85/75 °C), ‘fourth-generation’ (50/40 or 50/25 °C) or ‘fifth-generation’ (near ambient) water ...

Economic comparison of low-temperature and ultra-low-temperature district heating for new building developments with low heat demand densities in Germany

International Journal of Sustainable Energy Planning and Management, 2018
District heating risks to lose competitiveness the lower the linear heat density of a district is. The distribution network needs to be highly efficient in order to ensure economic feasibility.
