1. 6. 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. 7. Solar PV Integrated with Seasonal Thermal Storage and District Heating

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Lovisa Thalén; Hannah Ekström; [2023]
   Keywords : Solar PV; power-to-heat; heat pump; electric boiler; thermal seasonal storage; district heating; Technology and Engineering;

   Abstract : In order to contribute to reaching the climate goals of the future, power-to-heat (P2H) technologies are a possible solution. A heat pump (HP) or an electric boiler (EB) can be used to produce warm water by utilising cheap electricity from photovoltaic (PV) parks in the summer when there are many hours of sunlight.

4. 8. 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.

5. 9. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
   Keywords : GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

   Abstract : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. READ MORE
