2. 6. Domestic Heating with Solar Thermal : Studies of Technology in a Social Context and Social Components in Technical Studies

   Author : Magdalena Lundh; Ewa Wäckelgård; Jan-Erik Nielsen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar heating; solar energy; heating system; social components; market actors; interdisciplinary; heat storage; system solution; energy system; hot water; load profiles; socio-technical; Engineering physics; Teknisk fysik; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

   Abstract : Research in solar heating has traditionally focused solely on increasing the system efficiency by improving the technical components. In this thesis the technical methodology and system boundaries are widened to connect the technical aspects with market actors that are highly influential on the implementation of solar technology.

4. 7. Smart control of PV and exhaust air heat pump systems in single-family buildings

   Author : Emmanouil Psimopoulos; Joakim Widén; Chris Bales; Tomas Persson; Jarek Kurnitski; Uppsala University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaics; heat pump; forecast services; thermal storage; electrical storage; control algorithms; TESHP Test av solvärmepumpsystem; TESHP Test av solvärmepumpsystem;

   Abstract : Recently, decentralized household photovoltaic (PV) systems have become more affordable and there is a tendency to decrease subsidies for the PV excess electricity fed into the grid. Therefore, there is growing interest in methods to increase the self-consumption (SC), which is the part of the electricity produced by PV and directly consumed on buildings. READ MORE

5. 8. Studies of the flow pattern in short term hot water storages

   Author : Pascal Veber; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : This thesis relates to the study of thermally stratified hot water storages used in district heating systems and is an extension of the doctoral theses of Jan Dahl and Roger Hermansson. The thermal performance of a stratified water storage is reduced by different phenomena such as heat transfer to the surroundings and mixing between hot and cold water during the charging of the tank.

6. 9. Evolution of Future Heating Systems - Modeling of an Expanding City Using a Dynamic Systems Approach

   Author : Karl Vilén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heating system; Thermal energy storage; Low-heat-demand housing; Dynamic energy systems modeling; Housing; District heating; Climate policy; TIMES;

   Abstract : Reducing greenhouse gas emissions is central to meeting climate change mitigation targets. Since the energy sector is one of the largest greenhouse gas emitters, it is essential that all the actors within the energy sector reduce their respective emissions. READ MORE

7. 10. Preparation and performance of energy storage materials and application for recovery of industrial waste heat

   Author : Weilong Wang; Jinyue Yan; Fredrik Setterwall; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase change materials; Polyethylene glycol; Silicon dioxide; Form-stable; Thermal conductivity; Expanded graphite; Industrial heat; M-TES; ; Chemical energy engineering; Kemisk energiteknik;

   Abstract : Due to the rapid increase of energy consumption and the environmental concerns on climate change caused by the fossil fuel combustion, it becomes a big issue on how to use alternative renewable energy resources to replace fossil fuel and to improve energy utilization efficiency. In Sweden, there are plenty of detached buildings without connection with district heating (DH) network, which use oil to supply the hot water for space heating and tap water. READ MORE
