1. 1. Enabling industrial energy benchmarking : Process-level energy end-use, key performance indicators, and efficiency potential

   Författare :Elias Andersson; Patrik Thollander; Magnus Karlsson; Martin Patel; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; energy efficiency potential; energy benchmarking; manufacturing industry; key performance indicators; industrial energy end-use;

   Sammanfattning : One of the greatest challenges of our time is global climate change. A key strategy for mitigating the emission of greenhouse gases is the improvement of energy efficiency. Manufacturing industry stands for a large share of global energy end-use but has yet to achieve its full energy efficiency potential. LÄS MER

3. 2. Visualisera energi i hushåll : Avdomesticeringen av sociotekniska system och individ- respektive artefaktbunden energianvändning

   Författare :Erica Löfström; Kajsa Ellegård; Jenny Palm; MariAnne Karlsson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy use; energy visualization; households; energy behaviour; Power Aware Cord; Anneberg; pilot project; heating system; time-diaries; Time-PAcTS; Energianvändning; energivisualisering; hushåll; energibeteende; Power Aware Cord; Anneberg; pilotprojekt; värmesystem; tidsdagbok; Time-PAcTS; Technology and social change; Teknik och social förändring;

   Sammanfattning : Ett centralt problem i strävan efter att minska energianvändningen i hushåll genom beteendeförändringar är att energi till stora delar är en osynlig produkt. Avhandlingen strävar efter att utveckla kunskap som kan bidra till mer hållbar utveckling genom att analysera tre företeelser som på ett konkret sätt synliggör energi och energirelaterat beteende: ett lokalt värmesystem, en s.

4. 3. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes

   Författare :Wahib Owhaib; Björn Palm; Tassos Karayiannis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Minichannel; microchannel; heat transfer; pressure drop; single-phase; two-phase; flow boiling; flow visualization; dry out; bubble behavior; flow pattern.; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. LÄS MER

5. 4. 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

7. 5. Phase Change Phenomena During Fluid Flow in Microchannels

   Författare :Rashid Ali; Björn E Palm; Gian Piero Celata; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microchannels; Boiling; Heat Transfer; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

   Sammanfattning : Phase change phenomena of a fluid flowing in a micro channel may be exploited to make the heat exchangers more compact and energy efficient. Compact heat exchangers offer several advantages such as light weight, low cost, energy efficiency, capability of removing high heat fluxes and charge reduction are a few to mention. LÄS MER
