    Sammanfattning : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. LÄS MER

  3. 2. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hoda Mahmoodi; [2023]
    Nyckelord :Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

    Sammanfattning : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. LÄS MER

  4. 3. Impact of Implementing CCS Technology on a Biomass Power Plant

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Azin Mohebbi; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This study examines the implementation of carbon capture and storage (CCS) technology, specifically the monoethanolamine (MEA) chemical absorption method, in a biomass power plant. The aim is to assess the energy requirements and optimize the solvent processes to improve the overall efficiency of the carbon capture process. LÄS MER

  5. 4. Energy renovation packages for the decarbonisation of Swedish multifamily buildings

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Bhavik Daya; Hugh Nolan; [2022]
    Nyckelord :Decarbonisation; Renovation; Multi-family homes; Life Cycle Assessment; Life Cycle Costing; Technology and Engineering;

    Sammanfattning : Sweden and Europe aim to be carbon neutral by 2045 and 2050 respectively. Upgrading the existing building stock has been identified as having great potential in assisting to realise these goals. LÄS MER

  7. 5. Experimental investigation of ventilation performance of corner placed stratum ventilation in an office environment

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Gasper Choonya; [2019]
    Nyckelord :Stratum ventilation; local air change index; air change efficiency; ventilation effectiveness; draught rate; percentage dissatisfied; heat removal effectiveness;

    Sammanfattning : Energy use in buildings account for about one third of the total global energy supply and contributes as much as 30% of the anthropogenic greenhouse gas emissions. It is estimated that energy use in buildings will increase to 67% by 2030. LÄS MER
