A contribution to the simplified determination of heat distribution costs in linear and radial district heating networks
type: CreativeWork
description: District heating networks offer a great opportunity to make a significant contribution to the success of the energy transition, assuming that low-carbon heat supply is achieved. District heating networks have advantages over individual building heat supply systems, such as lower heat generation costs due to economies of scale, higher efficiencies in heat production, and the ability to integrate heat from various sources. However, district heating networks are not unconditionally advantageous, as they require an investment in network infrastructure, unlike individual building heat supply systems. Whether this investment outweighs the economic benefits on the heat supply side depends on a variety of factors and cannot be answered in general. In the literature, two methods are described for assessing the suitability of an area for district heating supply. The use of detailed network simulations allows for an accurate determination of heat distribution costs but requires significant expertise and effort in application. On the other hand, territorial assessment approaches rely on easily identifiable indicators from urban planning, but their accuracy is limited. Furthermore, the later methods often rely on data from existing district heating networks, raising doubts about their applicability to future generations of district heating networks. Therefore, the aim of this thesis is to develop a methodology for estimating heat distribution costs that does not rely on design parameters from existing district heating networks. This methodology aims to combine the advantages of territorial assessment approaches (ease of use) and detailed network simulations (accuracy). To achieve this, the main influencing factors will be identified to derive multiple methods for determining the costs of future heating networks. Additionally, the accuracy and limitations of these methods is analyzed. This thesis primarily focuses on analyzing the heat distribution costs of linear networks. Addit…
