    Keywords : Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

    Abstract : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. READ MORE

  3. 2. Dynamic Modeling of Heat Power System : Modeling of a Heat Power System Using Physical and Data-driven Methods and Investigation of a Moving Boundary Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Albin Gustafsson; [2023]
    Keywords : System identification; Dynamic modeling; Organic Rankine cycle; Moving boundary; Thermodynamics.; System identifikation; Dynamisk modellering; Organisk Rankinecykel; Rörliga randvillkor; Termodynamik.;

    Abstract : Our society is becoming more and more electrified every day. However, a significant portion of the world’s electricity generation relies on the combustion of fossil fuels to produce heat, which is subsequently harnessed to generate electricity. One way of generating electricity from heat is by utilizing a Rankine cycle. READ MORE

  4. 3. 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.

  5. 4. 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.

  6. 5. Prioritizing Efficiency : Evaluating the Impact of Energy-Saving Measures in Commercial Buildings

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Matilda Hallin; [2023]
    Keywords : ;

    Abstract : This study systematically categorizes energy efficiency measures in buildings and evaluates their effectiveness in terms of energy savings, CO2e emissions reduction, and cost-effectiveness. It also explores the potential correlations between measure effectiveness and various building characteristics. READ MORE
