  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. Solar - Biomass hybrid system for process heat supply in medium scale hotels in Sri Lanka

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Asela Janaka Abeywardana; [2016]
    Keywords : solar energy; concentrated solar thermal technology; linear fresnel; biomass technology; wood-fired boiler; solar potential in Sri Lanka; feasibility study; life cycle cost; simple payback; return on invesment;

    Abstract : This study aimed at evaluating and demonstrating the feasibility of using Concentrated Solar Thermal technology combined with biomass energy technology as a hybrid renewable energy system to supply the process heat requirements in small scale industries in Sri Lanka. Particularly, the focus was to apply the concept to the expanding hotel industry, for covering the thermal energy demand of a medium scale hotel. READ MORE

  6. 5. Carbon dioxide in ice rink refrigeration

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : TUYET NGUYEN; [2013]
    Keywords : CO2; carbon dioxide; ice rink; refrigeration; CO2; koldioxide; kylsystem; ishall;

    Abstract : The average energy consumption of one ice rink is around 1000MWh/year, which approximately69% is occupied by the refrigeration unit and heating demand. With the aim of decreasing theenergy consumption, a new concept of refrigeration system with CO2 as a refrigerant has beendeveloped and it is promising to become a high potential next generation for refrigeration systemin ice rink.
