1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Fawzi Kayali; [2023]
   Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

3. 2. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Oskar Sundberg; [2023]
   Nyckelord :geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

   Sammanfattning : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. LÄS MER

4. 3. Integration of a heat recovery system in a Spray Drying Process : Model Simulation Analysis and Economic Feasibility

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Marcel Hott Oller; [2023]
   Nyckelord :Spray Drying; Heat pump; Simulation model; heat recovery system;

   Sammanfattning : The spray drying process is widely established in the industry worldwide. However, due to its complexity in predicting variables, the technology is often regarded as a "Black box" process. LÄS MER

5. 4. Methodology for Designing Bespoke Air Handling Units

   Master-uppsats, KTH/Energiteknik

   Författare :Alexandra Malysheva; [2023]
   Nyckelord :bespoke air handling unit; evaporative cooling system; two-stage crossflow heat exchanger; 3D-modeling; platsbyggt luftbehandlingsaggregat; evaporativt kylsystem; tvåstegs motströmsvärmeväxlare; 3D-modeling;

   Sammanfattning : This master's thesis explores the role of bespoke air handling units in enhancing energy efficiency in existing buildings. The context for the study is set against the backdrop of global initiatives, including the United Nations' Sustainable Development Goals, specifically Goal 7, which emphasizes the need to improve energy efficiency to combat climate change.

7. 5. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

   Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Cyrus Ourak Pour; [2023]
   Nyckelord :COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

   Sammanfattning : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.
