  1. 1. Data Centres as Prosumers: A Techno-Economic Analysis

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Jeremy Ericsson Sintong; [2023]
    Nyckelord :Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Sammanfattning : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. LÄS MER

    Nyckelord :KPI; time-based availability; energy-based availability; revenue-based availability; wind turbine availability;

    Sammanfattning : Different key performance indicators are used to assess various aspects of a wind turbine (performance, reliability, financial aspects…). Availability metrics mainly, time-based and energy-based availability are the main indicators used to monitor and evaluate turbine’s availability performance today. LÄS MER

  5. 4. An evaluation of the influential factors on energy performance: A case study of a shopping mall

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Maryam Rabitabar; [2022]
    Nyckelord :Energy; building performance; relations; measured data; data analysis; Pearson Correlation Coefficient; statistical method; HVAC systems; complex building; shopping malls; Technology and Engineering;

    Sammanfattning : Shopping malls are becoming more prevalent throughout the world. They have been identified as having high energy use, which is less explored than other building types. There are 357 shopping centers in Sweden, which has doubled in the last five years. LÄS MER

  7. 5. En komparativ studie av tillgängligheten hos likströmssystem utifrån deras uppbyggnad.

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Elias Holmberg; [2022]
    Nyckelord :Availability; DC-systems; Tillgänglighet; Likströmssystem;

    Sammanfattning : Den här rapporten undersöker tillgängligheten hos fyra olika likströmssystem vid ett svenskt kärnkraftverk.   Detta görs genom att analysera underhållsdokumentation och annan dokumentation från anläggningen samt därifrån beräkna mått för funktionssäkerhet och underhållsmässighet.
