  1. 1. District Heating and CHP Local Possibilities for Global Climate Change Mitigation

    University dissertation from Linköping : Linköpings universitet

    Author : Kristina Difs; Linköpings universitet.; Linköpings universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; combined heat and power; carbon dioxide emissions; optimisation; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. READ MORE

  2. 2. District heating in future Europe Modelling expansion potentials and mapping heat synergy regions

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Urban Persson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Abstract : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

  3. 3. District heating comes to town : The social shaping of an energy system

    University dissertation from Linköping : Linköpings universitet

    Author : Jane Summerton; Linköpings universitet.; Linköpings universitet.; [1992]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; district heating; municipal technology; energy system; pipeline; large t<:chnical system; actor network; multiorganization; grid; grid-based energy system; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This thesis deals with the introduction of district heating in an "ordinary" Swedish town: Mjölby. The process was initiated in 1974 and the decision to build was taken in 1979. In the following years pipelines were laid down and the system was gradually built. In 1987, a permanent heat plant was ready to assume operation. READ MORE

  4. 4. Realise the Potential! Cost Effective and Energy Efficient District Heating in European Urban Areas

    University dissertation from Gothenburg : Chalmers University of Technology

    Author : Urban Persson; Högskolan i Halmstad.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width; district heating;

    Abstract : The Member States of EU27 need to accelerate the integration of energy efficient technology solutions to reach the 20% energy efficiency target set for 2020. At current pace, projections indicate that only half of expected primary energy reductions will be reached. READ MORE

  5. 5. District Heating Development : Prosumers and Bottlenecks

    University dissertation from Department of Energy Sciences, Lund University

    Author : Lisa Brange; Lunds universitet.; Lund University.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Prosumers; Bottlenecks; Pressure; Differential pressure; Planning; Simulations;

    Abstract : The overarching objective of the studies in this thesis is to solve issues associated with the current district heating development in order to improve the efficiency, and thus the environmental performance, of district heating systems. More specifically, the aim is to solve issues related to prosumers and bottlenecks in district heating networks. READ MORE
