  1. 1. Värme från gruvvatten : En undersökning av olika metoder för att kunna hämta värme ur vattnet som pumpas upp ur gruvorna

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Glas Mathilda; [2023]
    Nyckelord :gruvvatten; värmepump; värmeväxlare; kollektor;

    Sammanfattning : Boliden Mineral AB - Boliden Mines is a company that carries out continuous improvement work in the energy and environmental area. During this degree project, the possibility of making use of waste heat from the mine water that is pumped out of the Renström mine was evaluated. LÄS MER

  3. 2. Investigating the effect of grinding method on ore beneficiation behaviour

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Mellisa Tanaka Mundida; [2023]
    Nyckelord :flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Sammanfattning : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. LÄS MER

  4. 3. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

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

    Författare :Malin Gelfgren; [2023]
    Nyckelord :;

    Sammanfattning : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. LÄS MER

  5. 4. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mila Ebrahim; [2021]
    Nyckelord :Solar energy; Renewable energy; Photovoltaic thermal collector; PV Thermal; PVT Collector; Performance; Numerical modelling; COMSOL Multiphysics; Ground Source Heat Pump; Solenergi; Förnybar energi; kominerad solcell solfångare; PVT panel; Prestanda; Numerisk modellering; COMSOL Multiphysics; Bergvärme;

    Sammanfattning : In Photovoltaic/Thermal (PVT) technology, both PV and solar thermal technology are integrated in the same module for simultaneous electricity and heat production. Research has shown that there are multiple benefits from integrating PVT collectors with a ground source heat pump (GSHP) system, since it allows for seasonal storage of thermal energy over the year.

  7. 5. Fjärrvärmedriven Absorptionskyla : En ekonomisk undersökning av olika spetslösningar

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Bodil Strömqvist; [2021]
    Nyckelord :Absorption chiller; peak load solution; district cooling; district heating driven cooling; Absorptionskyla; spetslösning; fjärrkyla; fjärrvärmedriven kyla;

    Sammanfattning : This independent degree project has been implemented on behalf of FVB Sverige AB in collaboration Sundsvall Energi AB with the initial purpose of mapping manufacturers of hot water driven absorption chillers. After that, several technical solutions are examined to manage the peak load of a theoretical object which cannot produce the cooling power required with only an absorptions chiller, due to limitations in the district heating supply.
