  1. 1. Making grid capacity available through heat pump control

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Karin Arding; Siri In de Betou; [2019]
    Nyckelord :Grid; capacity; electricity; Uppsala; IKEA; peak shaving; electric bus; bus depot; lumped capacity model; Region Uppsala;

    Sammanfattning : In this report the problem of constructing a bus depot with electrical buses despite the lack of grid capacity, was analyzed. A potential solution is investigated, namely smart control of heat pumps in industries. LÄS MER

  2. 2. Modelling of Heat Transfer for Convection-boosted Flat Vertical Radiator Surfaces : An investigation of how heat transfer is influenced by radiator height and freestream air velocity

    Master-uppsats, KTH/Strömnings- och klimatteknik

    Författare :Oskar Scheibe; [2017]
    Nyckelord :Heat transfer; flat vertical plate; non-isothermal; temperature profile; radiator; energy efficiency;

    Sammanfattning : In this thesis, a calculation model is created to study a theoretical radiator-like configuration, consisting of a flat vertical plate heated with a constant capacity rate. This lumped capacitance model is partly created to more theoretically look at radiators with add-on-fans, but also to in such a setting look at fundamental heat transfer relationships. LÄS MER

  3. 3. Using a lumped conceptual hydrological model for five different catchments in Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Madeleine Ekenberg; [2016]
    Nyckelord :;

    Sammanfattning : Hydrological models offer powerful tools for understanding and predicting. In this thesis we havereviewed the advantages and disadvantages of physically based distributed hydrological models andconceptually lumped hydrological models. LÄS MER

  4. 4. Optimization of Solar Energy to foster the Evaporative Crystallization Process at Lake Katwe, Uganda

    Master-uppsats, Högskolan i Gävle/Akademin för teknik och miljö

    Författare :Joseph Ddumba Lwanyaga; [2013]
    Nyckelord :Solar; Salt; Crystallisation.Evaporation;

    Sammanfattning : Lake Katwe located in Kasese district, is an explosion crater in western rift valley and is the largest of the eight explosion crater lakes in the Katwe-Kikorongo volcanic field, containing a renewable source of natural mineral salts. Salt is produced for 6 months of the year during the dry seasons. LÄS MER

  5. 5. Supply modulation study for Ericsson MINI LINK

    H-uppsats, Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Författare :Björn Herrmann; [2011]
    Nyckelord :;

    Sammanfattning : This report presents a feasibility study of envelope tracking for Ericssons radio link system. The analysis is done based on a model of an existing 7 GHz GaAs Power amplifier. From the on the model based analysis the theoretical PAE was found to be 50% compared to the 15% achieved through static biasing. LÄS MER
