    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. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis

    University essay from KTH/Energiteknik

    Author : Julia Linnea Hildur Almebäck; Rebecka Magnius; [2022]
    Keywords : Heat Recovery; Heat Export; Supermarkets; Refrigeration Systems; CO2 Transcritical Booster Systems; Energy Efficiency; Värmeåtervinning; värmeexport; livsmedelsbutiker; kylsystem; CO2 transkritiskt boostersystem; energieffektivitet;

    Abstract : Supermarkets have a high energy demand where almost half of the energy is used within the refrigeration system. The refrigeration system utilises a cycle where heat is taken and rejected. The rejected heat could be recovered and utilised for other purposes, such as covering internal heating demand or be exported to other facilities. READ MORE

  4. 3. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

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

    Author : Mantas Petrosius; [2021]
    Keywords : ;

    Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
