    Sammanfattning : With more restrictions regarding the use of refrigerants with high GWP-values, refrigeration systems that uses R744 (Carbon dioxide) as a refrigerant increases. Supermarkets are energy intense facilities where the refrigeration system utilize a significant part of the total utilized energy. LÄS MER

  4. 23. The Energy Savings Potential of a Heat Recovery Unit and Demand Controlled Ventilation in an Office Building

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Martin Fagernäs; [2021]
    Nyckelord :Demand Controlled Ventilation; DCV; Heat Recovery Unit;

    Sammanfattning : The building sector is responsible for approximately 40 % of the total energy usage in Sweden. In office buildings the heating, ventilation and air conditioning system can account for up to 55 % of the energy usage. In order to reduce the energy usage of the heating, ventilation and air conditioning system different control methods are often used. LÄS MER

  5. 24. Evaluation of natural materials in Sustainable Buildings : A potential solution to the European 2050 long-term strategy
