  1. 6. 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

  3. 7. Modeling and Evaluation of High Temperature PEM Fuel Cells for Truck Applications

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Johannes Wrangstål; Marcus Ögren; [2022]
    Nyckelord :Modeling; Fuel Cell; FCHEV; HTPEM; LTPEM; ECMS; High temperature proton exchange membrane;

    Sammanfattning : With increasing demands on lowering carbon emissions, fuel cell hybrid electric vehicles (FCHEV) have been seen as an alternative to the fossil-fuel driven trucks of today. These would have less emissions and strive to have the same range as any diesel driven transport vehicle. LÄS MER

  4. 8. Techno-economic analysis of power‑to‑heat‑to‑power storage for a residential building

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Alicia López de Ceballos Regife; [2021]
    Nyckelord :Solar energy; storage; PV installation; Li‑ion; residential sector; latent heat; high temperature; hot water tank; hybrid PV; heat pump; self-consumption; CHP; optimization; Nedler and Mead.;

    Sammanfattning : Despite the share of renewable energies worldwide is increasing, which can help in reducing the CO2 emissions, their unpredictability has become a problem due to the mismatch between generation and demand. Among the different alternatives to solve this problem, energy storage is a very interesting solution. LÄS MER

  5. 9. 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.
