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

    Author : Sandra Parra Gimeno; [2023]
    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. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Ellinor Carolina Salomonsson; [2023]
    Keywords : Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Abstract : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. READ MORE

  4. 3. Litteraturstudie - Energieffektivisering av livsmedelsbutiker genom nyttjande av överskottsvärme

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

    Author : Christ Asadour; Teodor Nymark; [2023]
    Keywords : ;

    Abstract : Generellt sett har livsmedelsbutiker ett stort behov av enrgi i form av el, värme, komfortkyla och livsmedelskyla. Livsmedelsbutikers höga elanvändning utgör 3% av Sveriges totala elanvändning. En betydande del av elanvändningen går till kylsystem och genererar på så vis överskottsvärme från kondensorn som ofta slösas bort. READ MORE

  5. 4. Comparative Analysis of Modern Energy Systems for Ice Rinks

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

    Author : Pendar Hemati; [2023]
    Keywords : Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    Abstract : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. READ MORE
