  4. 18. Utveckling av driftstöd för planering av fjärrkyla : En explorativ studie om utvecklingen av ett optimeringsbaserat driftplaneringsverktyg för fjärrkylanätet City i Linköping, Sverige

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Christian Haapanen; Louise Hedenskog; [2023]
    Nyckelord :District cooling; MILP; UC problem; Optimization; Operational plan; Smart energy systems; Fjärrkyla; MILP; UC problem; Optimering; Driftplanering; Smarta energisystem;

    Sammanfattning : The average global temperature is rising due to climate change. This leads to an increase in cooling demand along with higher usage of electricity to operate cooling processes. One way to decrease the electricity usage is to introduce absorption cooling which uses heat instead of electricity as its main source of power. LÄS MER

  5. 19. Challenges and success factors for scaling up an upcycling value chain : A case study and material flow analysis on public school craft classes in Stockholm

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik
