  2. 2. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Jonathan Karlsson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

    Abstract : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

  3. 3. Advances in Thermal Insulation Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Thomas Thorsell; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

    Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE

  4. 4. Thermal response test in situ measurements of thermal properties in hard rock

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Signhild Gehlin; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : In-situ determination of thermal properties in bedrock is important for the sizing of larger BTES systems. In-situ values of thermal conductivity may reduce required borehole length up to 30%. This thesis treats a new mobile thermal response test equipment (TED), developed in Luleå, Sweden, 1995-98.

  5. 5. Characterization and Compensation of Thermal Effects in GaN HEMT Technologies

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Johan Bremer; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrothermal; temperature compensation.; AlGaN GaN; thermal coupling; characterization; thermal effects; thermal resistance;

    Abstract : Further advancements with GaN based technologies relies on the ability to handle the heat flux, which consequently arises from the high power density. Advanced cooling techniques and thermal optimization of the technology are therefore prioritized research areas. READ MORE
