  1. 1. On The Evaluation of District Heating Load Predictions

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Herman Hansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : District Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology.

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Tandin Jamtsho; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Food production is a critical component of global livelihoods and economic revenue. However, storing harvested food presents challenges in minimizing post-harvest losses. Among various methods, food drying has emerged as a popular technique for preserving food during off-seasons. LÄS MER

  7. 5. Grundisolering för flerbostadshus : Jämförelse av cellglas och cellplast avseende energieffektivisering, ekonomiska aspekter och miljöpåverkan

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Samir Akhras; Mustafa Arab; Ahmed Yasin; [2023]
    Nyckelord :Thermal insulation; cellular glass insulation; expanded polystyrene insulation EPS ; extruded polystyrene insulation XPS ; energy balance; moisture; specific heat losses and life cycle analysis.;

    Sammanfattning : Purpose: This project compares two foundation insulation materials: cellular plastic and cellular glass. Currently, cellular plastic is the most used material for foundation insulation. While cellular glass is not widely utilized. Its disadvantage lies in its higher cost, which makes contractors prefer the cheaper alternative, cellular plastic. LÄS MER
