  1. 16. Microstructural characterization of quench annealed duplex SAF 2507 utilizing EBSD

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Simon Beyermann; [2022]
    Nyckelord :sigma phase; chi phase; electron backscatter diffraction; super duplex stainless steel; recrystallization; SAF 2507 UNS S32750 .;

    Sammanfattning : Producing large bars of duplex stainless steel free from precipitated embrittling phases isdifficult due to the many factors that influence precipitation. Research shows that intermetallicslike sigma and chi deteriorate principal material properties for the main application areas. LÄS MER

  3. 17. Data center cooling solutions : A techno-economical case study of a data center in Sweden

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

    Författare :Joel Sjökvist; Fredrik Magnusson; [2022]
    Nyckelord :Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

    Sammanfattning : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. LÄS MER

  4. 18. 5th Generation District Heating and Cooling : A High-Level Simulation Model of a Novel District Energy Network

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

    Författare :Viktor Olofsson; [2022]
    Nyckelord :5GDHC; district heating; district cooling; district energy; energy systems; renewable energy;

    Sammanfattning : 5th generation district heating and cooling is a novel approach to district heating and cooling networks. Instead of a centralized energy supply, the technology relies on multiple building-level energy centers, equipped with heat pumps and chillers. LÄS MER

  5. 19. Comparative simulation of PVT designs for three locations in Europe with different simulation tools

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :María Teresa Rodríguez Rubio; [2022]
    Nyckelord :Agriculture; Energy; European Commission; Horizon 2020; Innovation Project; Livestock farms; Renewable Energy; RES4LIVE; Solar Energy;

    Sammanfattning : In this thesis, different types of PVT (photovoltaic-thermal collectors) for three different farms in Europe will be studied, as part of the RES4LIVE project from the European Union’s Horizon 2020 Research and Innovation Action programme. A suitable renewable energy system will be proposed for each farm, considering the temperature range requirement and the climate conditions in each farm. LÄS MER

  7. 20. Single Sided Bonding of Cylindrical Battery Cells

    Master-uppsats, KTH/Industriell produktion

    Författare :Xu He; [2021]
    Nyckelord :cylindrical battery cell; single side bonding; ultrasonic wire bonding; cylindrisk battericell; enkelsidig bindning; ultraljudstrådsbindning;

    Sammanfattning : Over the last ten years the Li-ion battery cells plays a significant role in the world’s decarbonization and reduction of CO2 emission. They are widely applied in many industries, such as consumer electronics, transportation and energy storage industries. LÄS MER
