  1. 21. Adaptation of Solar Energy Driven Absorption Chillers for Air Conditioning in Commercial Building

    Master-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Ranjith Shantha De Silva Kalinga; [2017]
    Nyckelord :;

    Sammanfattning : The most recent analysis of energy usage in the country reveled that nearly 50% of the power generation is used for air conditioning and mechanical ventilation most of which is used by commercial organizations. The grid generation mix that contains a high percentage of fossil fuel makes such energy usage environment unfriendly. LÄS MER

  3. 22. Fjärrvärmeburen kyla

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Andreas Häggström; [2017]
    Nyckelord :;

    Sammanfattning : The purpose of this project has been to describe and compare different methods of airborne cooling from an economic long-term perspective to compare the profitability of investments. The heat-driven cooling methods of desiccant cooling and absorption cooling were compared with conventional compressor cooling as well as cold water cooling from the urban water supply network.

  4. 23. Determining the viscous splash losses in the housing of a hydraulic motor through CFD-simulations : A master thesis in collaboration with Bosch-Rexroth in Mellansel AB

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Tommy Larsson; [2017]
    Nyckelord :CFD computational fluid dynamics splash losses efficiency;

    Sammanfattning : One possible way of solving future energy shortages is by the optimization of our current energy consumption. These optimizations must span all possible fields of consumption. In the mechanical field radial piston hydraulic motors may show some margin of improvement. LÄS MER

  5. 24. Fjärrvärmedriven absorptionskyla i Hedemora och Säter

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Johan Boman; [2016]
    Nyckelord :absorptionskyla; absorptionskylmaskin; fjärrvärme; kylbehov; värmelast; komfortkyla; processkyla; systemtemperaturer; Hedemora Energi; Hedemora; Säter;

    Sammanfattning : Hedemora Energi produces and distributes district heating in Hedemora and Säter. It is during the summer in these cities, as in the rest of the country, a low heating demand. LÄS MER

  7. 25. Modelling a Solar Driven Absorption Heat Pump

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Pierre-Antoine Gigos; [2016]
    Nyckelord :Absorption Heat Pump; Solar Cooling; EES Model;

    Sammanfattning : Absorption Heat Pumps (AHP) have been developed since the late 19th century. They enable to produce cooling and heating directly from a heat source, unlike Compression Heat Pumps that require mechanical work. LÄS MER
