  1. 1. Exploring Urban Land Cover Changes and the Effect on Nocturnal Air Temperature Dynamics in Helsingborg - A temperature modeling made with TAPM

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Amanda Bäck; [2023-10-09]
    Nyckelord :Nocturnal Air Temperature; Intra-Urban Heat Island; Land Cover Classification; Deep learning; The Air Pollution Model TAPM ; Land Cover Change;

    Sammanfattning : In light of increasing global temperatures, urban areas face growing challenges related to heat stress. Alterations in land cover (LC) within cities contribute to changes in the intra-urban climate, predominantly driven by the replacement of vegetated surfaces with impermeable materials. LÄS MER

  3. 2. Modeling the Urban Heat Island in Gothenburg, Sweden: an analysis of the Urban Weather Generator Louise

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Louise Lindén; [2023-05-10]
    Nyckelord :urban climate; urban heat island; Urban Weather Generator; urban planning;

    Sammanfattning : Urban Heat Islands is a well-known phenomenon that has been observed in most cities around the globe. It is a night-time phenomenon occurring on calm and clear nights and is defined as the temperature difference between an urban area and its rural surroundings. LÄS MER

  4. 3. 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.

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mrunmayee Sonna; [2023]
    Nyckelord :IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

    Sammanfattning : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. LÄS MER

  7. 5. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

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

    Författare :WULLSCHLEGER LÉA; [2023]
    Nyckelord :Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER
