  3. 2. 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

  5. 4. 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

  6. 5. Energy Efficiency Assessment,based on Field Measurements andComputational Simulations : A Swedish Hypermarket’s case study

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