  1. 1. The role of absorption cooling for reaching sustainable energy systems

    Författare :Susanne Lindmark; Viktoria Martin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Absorption cooling; trigeneration; district cooling; humidified gas engine; waste heat; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : The energy consumption is continuous to increase around the world and with that follows the demand for sustainable solutions for future energy systems. With growing energy consumption from fossil based fuels the threat of global warming through release of CO2 to the atmosphere increases. LÄS MER

  3. 2. Heat driven cooling in district energy systems

    Författare :Magnus Rydstrand; KTH; []
    Nyckelord :District heating; district cooling; thermal storage; humidified gas turbines; combined heat and power; cooling;

    Sammanfattning : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. LÄS MER

  4. 3. Absorption of Sound : On the effects of field interaction on absorber performance

    Författare :Anna Färm; Mats Åbom; Ragnar Glav; Susann Boij; Gareth Bennett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; Porous absorbers; Bulk reaction; Local reaction; Boundary layer; Grazing flow; Temperature gradients; Surface impedance; Sound field; Pass-by noise; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. LÄS MER

  5. 4. Combined Electricity Production and Thermally Driven Cooling from Municipal Solid Waste

    Författare :Seksan Udomsri; Andrew R. Martin; Torsten Fransson; Erik Dahlquist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; incineration; hybrid cycle; power production; thermally driven cooling; absorption chillers; decentralized thermally driven cooling; district heating; Mechanical and thermal engineering; Mekanisk och termisk energiteknik; SRA - Energy; SRA - Energi;

    Sammanfattning : Increasingly intensive efforts are being made to enhance energy systems via augmented introduction of renewable energy along with improved energy efficiency. Resource constraints and sustained high fossil fuel prices have created a new phenomenon in the world market. LÄS MER

  7. 5. The open absorption system : energy savings in different applications

    Författare :Lars Johansson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands. LÄS MER
