  1. 1. Heat recovery from vacuum brazing furnaces

    Master-uppsats, Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Författare :Oliver Robertsson; Rasmus Wikman; [2023]
    Nyckelord :Waste heat; Vacuum furnace; Heat recovery; HVAC; Technology and Engineering;

    Sammanfattning : By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system.

  3. 2. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Hanna Grahn; Matilda Eriksson; [2023]
    Nyckelord :Large-scale heat pump; refrigerant; COP;

    Sammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  4. 3. Seawater Heat Recovery by the Utilisation of Phase Change Heat of Freezing : Technical feasibility study of a system for District Heating in the city of Helsinki

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Rakesh Ramesh; [2022]
    Nyckelord :District heating; Seawater; Ice slurry; Aspen Plus; Pressure drop; Fjärrvärme; Havsvatten; Isslurry; Aspen Plus; Tryckfall;

    Sammanfattning : With the Paris agreement calling to limit global warming to 2°C below pre-industrial levels, with further efforts to ensure it stays below 1.5°C, the Finnish government passed the Lakihiilen energiakäytön kieltämisestä (416/2019), i.e. LÄS MER

  5. 4. Experimental Evaluation of Time Study for Conventional Case Hardening at Härdservice

    Magister-uppsats,

    Författare :Binnu Kurian Mathew; Vishal Vijayan; [2022]
    Nyckelord :Case Hardening; Time Study;

    Sammanfattning : Heat treatment is the process of heating metal without allowing it to reach a molten state or melting, it and then cooling it in a controlled manner to choose desired mechanical qualities. Heat treatment aims to make the metal stronger, more malleable, more abrasion resistant, and more ductile. LÄS MER

  7. 5. Case study of the energy performance of a school building in Laholm, Sweden : Energy modeling for the formulation of efficient renovation strategies

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Daniel Andrés Gutiérrez Prieto; [2022]
    Nyckelord :Aerogel; building renovation; energy modeling; exergy analysis; new technologies; phase change materials; vacuum insulation panels.;

    Sammanfattning : This study has been focusing on a school located in the municipality of Laholm, South of Sweden. Employing an energy balance of the last five (5) years, a proposal for measures is made in terms of performance for comparison with the baseline of the current consumption trend. LÄS MER
