  2. 1. Optimization of ground-coupled systems for heating and cooling of buildings

    Author : Jüri Naumov; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-cooling; brine temperature; heat pump; ground system; heating demand; storage; building load; cooling demand; Borehole;

    Abstract : The use of ground-coupled systems in commercial buildings offers economic as well as environmental advantages. When both heating and cooling is required, a ground-coupled system can function both as a heat source and a heat sink. At the same time, it can also serve as a short term as well as a seasonal storage. READ MORE

    Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

  5. 3. Experimental and Theoretical Study of Rack Storage Fires

    Author : Haukur Ingason; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response time; in-rack sprinkler; flame heat transfer; gas velocity; gas temperature; flame height; in-rack fire plume; Rack storage fire; fire growth rate; Technological sciences; Teknik;

    Abstract : A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. READ MORE

  6. 4. Developments in Ground Heat Storage Modeling

    Author : Alberto Lazzarotto; Björk Folke; Michel Bernier; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole fields; g-functions; network; inclined; integrated design; Energy Technology; Energiteknik; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Ground heat storage systems can play an important role for the reduction of green house gases emissions by increasing the exploitation of renewable energy sources and “waste heat” with a consequent diminution of the use of fossil fuels.A ground heat storage consists in an array of vertical boreholes placed in such a way that promotes the mutual thermal interaction between the ground heat exchangers creating the necessary conditions required to effectively store and retrieve heat.

  7. 5. Life performance assessment methodologies for combined solar energy technologies : a case study on system parts in nordic climates

    Author : Bojan Stojanovic; Christer Sjöström; Björn Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life performance; assessment; combined solar energy technologies; degradation; component and system performance; Building engineering; Byggnadsteknik; Materials science;

    Abstract : The main questions concerning energy technologies today are their economical and environmental impacts. These entities are (at the present) assessed on the basis that operations proceed as newly installed/designed systems, during an assumed working life period. READ MORE
