  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.

  3. 2. Multi-Data Approach for Subsurface Imaging: Combining Borehole and GPR- Data for Improved Analysis

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

    Författare :Pontus Yngvesson; [2023]
    Nyckelord :Geofysik; Geoteknik; GPR; Borrhål; Dataanalys; Markradar;

    Sammanfattning : The investigation to understand the subsurface and its features has long been asubject of interest for various fields, including fields such as archaeology and infras-tructure projects. However, traditional excavation methods are often costly and time-consuming. LÄS MER

  4. 3. Passiva, hybrida och aktiva metoder för att tillgodose och minska kylbehov i ett flerbostadshus med påverkan av klimatförändring

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Niklas Åström; [2023]
    Nyckelord :;

    Sammanfattning : Climate change will have a big impact on the built environment especially relating to indoor climate and energy usage. Higher temperatures and insufficient adaptation to heat can have several negative side effects on occupants. LÄS MER

    Sammanfattning : Tailings storage facilities (TSFs) serve as structures for storing tailings, i.e., waste materials generated by the mining industry. LÄS MER

  7. 5. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

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

    Författare :Christopher Pourier; [2023]
    Nyckelord :Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Sammanfattning : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. LÄS MER
