  2. 2. On Premixed Gas Fuelled Stirling Engine Combustors with Combustion Gas Recirculation

    Detta är en avhandling från Division of Combustion Engines, Lund Institute of Technology

    Författare :Magnus Pålsson; Lund University.; Lunds universitet.; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Maskinteknik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; hydraulik; Mechanical engineering; hydraulics; vacuum technology; termodynamik; Termisk teknik; applied thermodynamics; Thermal engineering; heat pipe; ejector; solar energy; CGR; recirculation; EGR; catalytic combustion; premix combustion; Stirling engine; combustor;

    Sammanfattning : The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. LÄS MER

  3. 3. Energy Efficiency Improvements of Tumble Dryers -Technical Development, Laundry Habits and Energy Labelling

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Lena Stawreberg; Karlstads universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; domestic; energy efficiency; textile; energy labelling standard; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity. LÄS MER

    Sammanfattning : The global energy consumption, which increased ~84% during last thirty years, exceeded 1.4.1011 MWh in 2008. It is projected to increase another ~39% until 2030. LÄS MER

  5. 5. Multi-dimensional approach used for energy and indoor climate evaluation applied to a low-energy building

    Detta är en avhandling från Institutionen för konstruktions- och produktionsteknik

    Författare :Fredrik Karlsson; Bahram Moshfegh; Hazim Awbi; [2006]

    Sammanfattning : The building sector alone accounts for almost 40% of the total energy demand and people spend more than 80% of their time indoors. Reducing energy demand in buildings is essential to the achievement of a sustainable built environment. At the same time, it is important to not deteriorate people’s health, well-being and comfort in buildings. LÄS MER
