    Sammanfattning : Refrigeration plays a crucial role in many different sectors and consumes about 17% of the electricity produced globally. This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts. LÄS MER

  4. 3. Electron beam powder bed fusion of Nitinol : A development from production process window towards delicate structures

    Författare :Lin Zeyu; Amir Rashid; Carolin Körner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Engineering; Industriell produktion;

    Sammanfattning : Electron beam powder bed fusion (PBF-EB) is increasingly attracting attention for manufacturing the near-net shape parts due to its incomparable merits, such as free residual stress and superior mechanical performance. Nickel Titanium (NiTi) as the most widely used functional alloy, has not been systematically explored for manufacturing using PBF-EB despite the perfect vacuum and high temperature manufacturing environment.

  5. 4. Energy Efficiency through Thermal Energy Storage : Possibilities for the Swedish Building Stock

    Författare :Johan Heier; Viktoria Martin; Chris Bales; Signhild Gehlin; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Sammanfattning : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. LÄS MER

  7. 5. Client orchestration for the implementation of energy innovation in construction

    Författare :Charlotta Winkler; Kristian Widén; Eugenia Perez Vico; John Lindgren; Per-Erik Eriksson; Högskolan i Halmstad; []
