1. 1. The heat load in district heating systems

   Författare :Sven Werner; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; heat load; simulation; solar gain; air infiltration; natural ventilation; distribution heat losses; regression analysis; control systems;

   Sammanfattning : This thesis considers the composition of the daily heat load in six Swedish district heating systems supplying heat for space heating and hot water supply. The analysis was performed by bringing together a heat load model and series of daily heat load observations covering periods ranging from five to eleven years. LÄS MER

3. 2. Enhanced District Heating Technology : Maintaining Future System Feasibility

   Författare :Helge Averfalk; Sven Werner; Urban Persson; Mei Gong; Patrick Lauenburg; Kerstin Sernhed; Per-Olof Johansson Kallioniemi; Louise Ödlund; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : When heat demand and high temperature heat supply gradually decreases in the future, then it will effect district heating systems ability to compete on the heat market. A good way to mitigate less district heating feasibility is to operate systems with lower temperature levels and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

4. 3. Low-temperature District Heating : Various Aspects of Fourth-generation Systems

   Författare :Helge Averfalk; Sven Werner; Brian Elmegaard; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; low temperature; three-pipe systems; 4GDH-3P; District heating; low temperature; three-pipe systems; 4GDH-3P;

   Sammanfattning : With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

5. 4. "Den Evangeliska Mariavägen till enhet" : En studie av Paulina Mariadotters spiritualitet

   Författare :Birgitta Laghé; Sven-Erik Brodd; Yvonne Maria Werner; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Church studies; spirituality; mystic; prophetic; small tradition ; great tradition ; Mary; regular religious life; monastic life; Kyrkovetenskap; Church studies; Kyrkovetenskap;

   Sammanfattning : The dissertation deals with the mid-twentieth century development of regulated religious life in the Church of Sweden and how this was expressed in the Congregation of the Daughters of Mary of the Evangelical Way of Mary. It focuses on the foundress’ spirituality and the importance of this for the shaping of monastic life, as well as on the significance of mystic and prophetic experience for that spirituality.

7. 5. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems

   Författare :Lukas Lundström; Erik Dahlquist; Fredrik Wallin; Björn Karlsson; Jan Akander; Sven Werner; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; energy conservation; weather normalisation; typical meteorological year; building energy simulation; system analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. LÄS MER
