1. 1. Study case: The water-cooling effect on floating photovoltaic plants performance

   Master-uppsats, KTH/Energiteknik

   Författare :Alice Dragon; [2024]
   Nyckelord :Solar photovoltaic; Floating photovoltaic; Performance analysis; Thermal loss; Panel Efficiency; Cooling effect; Solceller; Flytande solceller; Prestandaanalys; Termisk förlust; Panelens effektivitet; Kylande effekt;

   Sammanfattning : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. LÄS MER

3. 2. Techno-economic analysis and simulation of low temperature district heating networks

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Ilia Iarkov; [2023]
   Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. 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.

5. 4. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

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

   Författare :LINDA YANG; [2023]
   Nyckelord :Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

   Sammanfattning : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. LÄS MER

7. 5. Förbättring av energieffektiviteten för villor genom att implementera grund geotermisk ventilation

   Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

   Författare :Saleem Toro; Bilet Haddad; Frank Slewa; [2023]
   Nyckelord :Climate change and CO2 emission; cooling heating; geothermal energy; renewable energy source and reliable; shallow geothermal ventilation; Effektivitet och besparing; förnybar energikälla och pålitlig; geotermisk energi; grund geotermisk ventilation; klimatförändring och CO2 utsläpp; kylning och uppvärmning;

   Sammanfattning : Introduction: The world is facing an economic crisis that has led to high energy prices in the EU. These high energy prices have been a contributing factor to the challenging economic situation in Sweden, affecting businesses, industries, and households. EU countries have limited access to energy and rely mostly on imports. LÄS MER
