1. 1. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Jakob Gunnarsson; [2023-05-10]
   Nyckelord :;

   Sammanfattning : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. LÄS MER

3. 2. Phase Change Material : Potential for increased fire resistance in concrete

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :William Toivanen; [2023]
   Nyckelord :Phase change material; concrete; fire resistance; integration into building materials; latent heat; melting;

   Sammanfattning : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. LÄS MER

4. 3. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

   Master-uppsats, Mittuniversitetet/Institutionen för kemiteknik

   Författare :Helena Viberg Nissilä; [2022]
   Nyckelord :phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

   Sammanfattning : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. LÄS MER

5. 4. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

   Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Författare :Thibault Desjonquères; [2022]
   Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

   Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

7. 5. Modelling an air handling unit, building and occupant, regarding energy, moisture and frost protection

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

   Författare :Marius Daugela; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Frost formation in heat exchangers is an often accruing issue in cold climates. The aim of the project is to calculate the risk of frost formation in different Swedish cities by modeling vapor and frost behavior in heat exchangers... LÄS MER
