1. 1. Heat Transfer Aspects of Using Phase Change Material in Thermal Energy Storage Applications

   Författare :Justin NingWei Chiu; Viktoria Martin; Luisa Cabeza; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; comfort cooling; phase change materials; heat transfer; Thermal energy engineering; Termisk energiteknik; Other materials science; Övrig teknisk materialvetenskap; Environmental engineering; Miljöteknik; SRA - Energy; SRA - Energi;

   Sammanfattning : Innovative methods for providing sustainable heating and cooling through thermal energy storage (TES) have gained increasing attention as heating and cooling demands in the built environment continue to climb. As energy prices continue to soar and systems reach their maximal capacity, there is an urgent need for alternatives to alleviate peak energy use. LÄS MER

3. 2. Latent Heat Thermal Energy Storage for Indoor Comfort Control

   Författare :NingWei Justin Chiu; Viktoria Martin; Motoi Yamaha; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Phase Change Material; Indoor Comfort; Heat Transfer; Termisk Energilagring; Fasändringsmaterial; Inomhuskomfort; Värmeöverföring;

   Sammanfattning : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. LÄS MER

4. 3. Heat Transfer Enhancement of Latent Thermal Energy Storage in Rectangular Components

   Författare :Amir Abdi; Viktoria Martin; Justin NingWei Chiu; Mohammed Farid; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Sammanfattning : Latent Thermal Energy Storage (LTES) is an interesting choice to storethermal energy in a sustainable energy system. The primary benefit of LTESis the relatively high latent heat of fusion of the materials, known as PhaseChange Materials (PCM), used in such a system as the storage medium. LÄS MER

5. 4. Low-temperature based thermal micro-grids: operation and performance assessments

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; active thermal micro-grid; substation operation; performance assessment; distributed heat resources; chauffage urbain basse température; micro-réseaux de chaleur urbains actifs; fonctionnement de la sous-station; évaluation de la performance; sources de chaleur distribuées; lågtemperatur fjärrvärme; aktiv fjärrvärmemikronät; fjärrvärmecentral operation; prestationsbedömning; distribuerada värmekällor; Energy Technology; Energiteknik;

   Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

7. 5. Phase Equilibrium-aided Design of Phase Change Materials from Blends : For Thermal Energy Storage

   Författare :Saman Nimali Gunasekara; Viktoria Martin; Justin NingWei Chiu; Torsten Fransson; Ana Ines Fernandez; KTH; []
