  1. 11. Dynamic simulation of Swedish residential building renovations and its impact on the district heating network

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Christopher Bay; Nicolás Pinzón Muñoz; [2023]
    Nyckelord :;

    Sammanfattning : As urbanization continues to rise, cities now account for two-thirds of the world's total energy consumption. The built environment alone contributes to 40% of total energy consumption and a third of total greenhouse gas emissions. With an additional 2. LÄS MER

  3. 12. Development of an integrated hybrid energy system model for cloud deployment

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Konrad Jackiewicz; [2023]
    Nyckelord :Heat Pump; Energy System Modelling; District Heating Systems; Smart Energy Systems; Technology and Engineering;

    Sammanfattning : This research paper investigates the technical feasibility, system requirements, performance characteristics, and potential for optimization of an industrial heat pump in a district heating system, using the Modelon Impact platform. The study aims to provide a comprehensive understanding of the benefits and limitations of using cloud-based simulation platforms for the design and analysis of industrial energy systems. LÄS MER

  4. 13. En undersökning om två alternativa ventilationsaggregat med kyla på en befintlig byggnad : FTX värmepump med roterande värmeväxlare eller Sorptiv kyla

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Mariam Punjani; Melanie Huerta Olivares; [2023]
    Nyckelord :Ekonomiskanalys; FTX; IV produkt; Kylmaskiner; LCC; LCA; Livscykelperspektiv; Miljöanalys; Munters; Sorptiv kyla; Ventilationsaggregat; Värmepump;

    Sammanfattning : This thesis is based on comparing two different air-ventilation systems with cooling in a building. Two systems are compared, the first one is FTX with heat pump and a rotating heat exchanger, and the second is a system with sorptive cooling. LÄS MER

  5. 14. Sustainable Urban Energy Transition for the City of Bitola, North Macedonia : A City-Scale Urban Building Energy Model
