  1. 16. Solar PV Integrated with Seasonal Thermal Storage and District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Lovisa Thalén; Hannah Ekström; [2023]
    Nyckelord :Solar PV; power-to-heat; heat pump; electric boiler; thermal seasonal storage; district heating; Technology and Engineering;

    Sammanfattning : In order to contribute to reaching the climate goals of the future, power-to-heat (P2H) technologies are a possible solution. A heat pump (HP) or an electric boiler (EB) can be used to produce warm water by utilising cheap electricity from photovoltaic (PV) parks in the summer when there are many hours of sunlight. LÄS MER

  3. 17. Åtgärder för energieffektivisering av vanliga småhus - En teoretisk fallstudie av en 70-talsvilla

    Kandidat-uppsats, Lunds universitet/Avdelningen för Byggnadsfysik

    Författare :Elin Moberg; Oscar Lugnegård; [2023]
    Nyckelord :70-tal; Renovering; VIP-Energy; Energi; Technology and Engineering;

    Sammanfattning : The construction and service sector currently accounts for over one-third of Sweden's total energy consumption. Energy issues are at the forefront, and society is striving for more sustainable development. At the same time, electricity prices are increasing, leaving many households with expensive bills for heating their houses. LÄS MER

  4. 18. Comparative Analysis of Modern Energy Systems for Ice Rinks

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

    Författare :Pendar Hemati; [2023]
    Nyckelord :Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    Sammanfattning : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. LÄS MER

  5. 19. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Hanna Grahn; Matilda Eriksson; [2023]
    Nyckelord :Large-scale heat pump; refrigerant; COP;

    Sammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  7. 20. Environmental sustainability of a low-temperature heating system : A case study

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Bogdan Kurasov; Ahmed Alchasov; [2023]
    Nyckelord :;

    Sammanfattning : Nowadays, 40% of annual global CO2-emission is caused by the building sector. 27% of these emissions are coming from building operations and the main use of energy in buildings is heating. LÄS MER
