  1. 1. Heat recovery from vacuum brazing furnaces

    University essay from Lunds universitet/Avdelningen för Installations- och klimatiseringslära

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

    Abstract : 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

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

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

    Abstract : 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.
