  1. 6. Buildings as thermal energy storage – Pilot test and large-scale implementation for district heating systems

    Författare :Johan Kensby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space heating; Heat load; Heat demand; District heating; Thermal energy storage; Demand side management; Buildings;

    Sammanfattning : Heat loads in a district heating system can exhibit significant variations within a single day, which sets problematic conditions for efficient heat generation. Short-term thermal energy storage (TES) can decrease these daily variations and make the conditions for generating heat more favorable. LÄS MER

  3. 7. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs

    Författare :Kurt Källblad; Institutionen för byggvetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Computer Programs; Windows; Infiltration; Comfort; Walls; Indoor Climate; Climate; Ventilation; Cooling Load; Heating Load; Buildings; Thermal Models; Building Physics; Energy; Byggnadsteknik;

    Sammanfattning : The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. LÄS MER

  4. 8. Small District Heating Systems

    Författare :Jochen Dahm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; small residential area; dynamic simulation; district heating;

    Sammanfattning : The objective of this work is to identify, from an economical point of view, the optimal system design and operation strategy for the district heating of a small residential area. The applied methodology is an overall approach on the heat distribution system, the house connection and the space heating system in the building, i.e. LÄS MER

  5. 9. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation

    Författare :Kristina Difs; G. Björn Karlsson; Louise Trygg; Thomas B. Johansson; Linköpings universitet; []
    Nyckelord :District heating; combined heat and power; carbon dioxide emissions; optimisation; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : 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. LÄS MER

  7. 10. Integrating Latent Heat Storage into Residential Heating Systems : A study from material and component characterization to system analysis

    Författare :Tianhao Xu; Samer Sawalha; Björn Palm; Justin NingWei Chiu; Tianshu GE; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase change material; thermal energy storage; heat pump; load shifting; space heating; Energy Technology; Energiteknik;

    Sammanfattning : Latent heat thermal energy storage (LHTES) systems can be coupled with heat pump (HP) systems to realize heat load shifting on demand side. With phase change material (PCM), well designed LHTES components exhibit high storage energy density and thus have large potentials to be integrated in residence where a compact energy storage solution is needed.
