  1. 1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

    Författare :Doris Dijak; Elin Torstensson; [2023]
    Nyckelord :Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

    Sammanfattning : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

    Sammanfattning : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). LÄS MER

  4. 3. Beyond the blueprint : a critical view on plans for transit-oriented development (TOD) in the new indonesian capital

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Ifa Nur Ainina; [2023]
    Nyckelord :TOD; walkability; transit; BRT; capital city; Indonesia; IKN; Nusantara; Sejong;

    Sammanfattning : Indonesia is relocating its capital city from Jakarta to a new city built from scratch called IKN (Ibu Kota Negara/Nusantara). Starting with the prioritized Government Precinct, the full relocation will be completed by 2045. LÄS MER

  5. 4. Convolution-compacted visiontransformers forprediction of localwall heat flux atmultiple Prandtlnumbers in turbulentchannel flow

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Yuning Wang; [2023]
    Nyckelord :Turbulent flow; Heat transfer; Vision transformer; Convolutional neural network; Machine learning;

    Sammanfattning : Predicting wall heat flux accurately in wall-bounded turbulent flows is critical for a variety of engineering applications, including thermal management systems and energy-efficient designs. Traditional methods, which rely on expensive numerical simulations, are hampered by increasing complexity and extremly high computation cost. LÄS MER

  7. 5. Modellering och Simulering av Värmehanteringssystem för Batteridrivna Elektriska Fordon (BEV)

    M1-uppsats, KTH/Produktionsutveckling

    Författare :Ismail Bajalan; Petter Nors; [2023]
    Nyckelord :Thermal management; HVAC; heating ventilation and air conditioning; BEV; battery electric vehicle; simulation; Simulink; Värmehantering; HVAC; värme- och ventilationssystem; BEV; batteridrivna elfordon; simulering; Simulink.;

    Sammanfattning : I detta examensarbete simuleras ett värmehanteringssystem i Matlab Simulink för en elektrisk lastbil, det för att värmehantera fordonets klimat. Där en värmepump används för nedkylning av kupé och batteri samt en PTC (elektrisk värmare) för uppvärmning av detsamma. LÄS MER
