  1. 1. Energy Efficiency through Thermal Energy Storage Possibilities for the Swedish Building Stock

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Heier; KTH.; Högskolan Dalarna.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Abstract : Behovet av värme och kyla i byggnader utgör en betydande del av ett lands totala energianvändning och att reducera detta behov är av yttersta vikt för att nå nationella samt internationella mål för minskad energianvändning och minskade utsläpp. En viktig väg för att nå dessa mål är att öka andelen förnyelsebar energi för kylning och uppvärmning av byggnader.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magdalena Lundh; Uppsala universitet.; [2009]
    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; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP 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.

  3. 3. Short term water heat storage : an experimental and numerical investigation of phenomena that affect the degree of thermal stratification

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Roger Hermansson; Luleå tekniska universitet.; [1993]
    Keywords : Energiteknik; Energy Engineering;

    Abstract : Thermal stratification was studied by measurements of the temperature and velocity fields in water heat storage's and by numerical simulations. The work includes experimental investigations in three model heat storage's of different size and comparisons to numerical simulations for two of the storages. READ MORE

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

    University dissertation from Västerås : Mälardalen University

    Author : Weilong Wang; Mälardalens högskola.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase change materials; Polyethylene glycol; Silicon dioxide; Form-stable; Thermal conductivity; Expanded graphite; Industrial heat; M-TES; ; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Chemical energy engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik 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

  5. 5. Low energy buildings equipped with heat pumps for high self-consumption of photovoltaic electricity

    University dissertation from Västerås : Mälardalen University

    Author : Richard Thygesen; Mälardalens högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The building sector is a prioritized area in the European Unions (EU) ambition to reduce the total final energy use by 20 %; lower the emission of greenhouse gases by 20 % and using energy 20 % more efficient by 2020. The residential sector in the European Union accounts for 27% of the un-ion’s final energy use and the EU views decentralized energy generation and heat pumps as important measures in reducing the energy demand in the building sector.
