Method of Evaluation of Efficiency Improvement Potential for District Heating Systems with Focus on Variable Speed Centrifugal Pumps

The goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. The effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. This is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...

Development of excess heat-based district heating -A case study of the development of excess heat-based district heating in two Swedish communities

This article identifies and elaborates on preconditions, drivers and barriers behind the development of excess heat based systems of district heating in Sweden. Industrial excess heat based district heating systems are considered generally resource-efficient since it could reduce the use of fossil fuels and emissions of greenhouse gases by saving primary energy for district heating companies su...

Thermal Transients in District Heating Systems

Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux keep temperature fixed but adjust velocity of the carrier (typically water) or keep the velocity flow steady but then adjust temperature at the heat producing source (heat plant). We study the latter sce...
