  2. 21. District Heating for Residential Areas with Single-Family Housing -with Special Emphasis on Domestic Hot Water Comfort

    Author : Tommy Persson; Energihushållning; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low heat density; District heating; single-family housing; domestic hot water comfort; domestic hot water control; heat losses; supply temperature; thermostatic valves; Energiforskning; Energy research; marketing strategies; market penetration;

    Abstract : The concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. READ MORE

  4. 22. Distributed wireless control strategies for district heating substations

    Author : Jonas Gustafsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : The overall fuel efficiency of district heating could clearly be improved by using new strategies for measurement and control. The potential for improvement is on the order of several percent. READ MORE

  5. 23. Evaluating System Consequences of Energy Co-operation between Industries and Utilities

    Author : Inger-Lise Svensson; Bahram Moshfegh; Thore Berntsson; Kornelis Blok; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Energy conservation, energy efficiency measures, and energy carrier conversion within the industry are extremely important issues in order to deal with energy resource depletion and the threats from global warming. In Swedish industry there is potential for reductions of carbon dioxide emissions and resource use through utilization of excess heat and conversion of compression cooling to other cooling technologies using less electricity.

  6. 24. System studies of the use of industrial excess heat

    Author : Sarah Broberg Viklund; Magnus Karlsson; Mats Söderström; Semida Silveira; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; waste heat; surplus heat; energy systems; greenhouse gas emissions; energy efficiency; energy policy; system studies;

    Abstract : Energy, materials, and by-products, can be exchanged between companies, having positive effects in the form of improved resource efficiency, environmental benefits, and economic gains. One such energy stream that can be exchanged is excess heat, that is, heat generated as a by-product during, for example, industrial production. READ MORE

  7. 25. Collaborative development of resource efficient district heating in Sweden

    Author : Sofia Persson; Olof Hjelm; Sara Gustafsson; Mikael Ottosson; Linköpings universitet; []
    Keywords : ;

    Abstract : An increased recovery of excess heat from industrial processes and thermal power generation could significantly reduce energy demands. Industrial excess heat-based district heating systems are generally considered resource efficient because they reduce the use of fossil fuels and the emissions of greenhouse gases. READ MORE
