1. 11. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

3. 12. Study into the Potential and Feasibility of a Standalone Solar-Wind Hybrid Electric Energy Supply System

   Författare :Getachew Bekele; Björn Palm; Philip Eames; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Speed; Sunshine Duration; Solar Radiation; Feasibility Study; Standalone System; Solar-Wind Hybrid; Thermal energy engineering; Termisk energiteknik;

   Sammanfattning : The tendency to use renewable energy resources has grown continuouslyover the past few decades, be it due to fear over warnings of globalwarming or because of the depletion and short life of fossil fuels or evenas a result of the interest which has developed among researchers doingscientific research into it. This work can be considered as joining any ofthese groups with an objective of giving electric light to the poorpopulation living in one of the poorest nations in the world. LÄS MER

4. 13. Combined solar and pellet heating systems : Study of energy use and CO-emissions

   Författare :Frank Fiedler; Rebei bel Fdhila; Wolfgang Streicher; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heating; pellet heating; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

   Sammanfattning : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. LÄS MER

5. 14. Development of a Novel Gas Turbine Simulator for Hybrid Solar-Brayton Systems

   Författare :Tianyao Pan; Björn Laumert; Wujun Wang; Konstantinos Kyprianidis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine simulator; concentrating solar power; hybrid solar-Brayton system; pressure controller; choked nozzle; Programmable logic controller; proportional solenoid valve.; Gasturbinsimulator; koncentrerad solenergi; hybrid solenergi-Brayton-system; tryckregulator; strypt munstycke; programmerbar logikkontroller; proportionell magnetventil.; Energiteknik; Energy Technology;

   Sammanfattning : Hybrid solar-Brayton systems utilize both solar thermal energy and supplementary renewable fuels to provide controllable and dispatchable power output, which renders them a promising way to meet the growing energy demand and reduce the carbon footprints. However, existing testing facilities for key components in such hybrid systems often fail to accomplish the testing requirements, hence impeding the improvement of the renewable energy share and the overall efficiency.
