    Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

  3. 2. Installation av rör- och värmeväxlarsystem för spillvärmeåtervinning vid Boliden Rönnskär

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Lindberg; [2021]
    Nyckelord :Rör installation; Spillvärme; Energiåtervinning;

    Sammanfattning : Rönnskärsverken in Skelleftehamn is a smeltery owned by Boliden. Rönnskär receives raw materials from Boliden´s mines and electronic materials. The metals that are mined at Rönnskär are mainly copper, lead and zinc, as well the precious metals silver and gold, where copper is the largest volume of the metal production. LÄS MER

  4. 3. Integrating Ground Source Heat Pumps into Elderly Homes as Energy-efficient Heating and Cooling Solution - A Swedish Case Study

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

    Sammanfattning : Energy efficiency and environmental questions have gained increased attention over the last decade. In combination with global warming and increasing cooling demands, the Swedish market for combined heating and cooling solutions such as ground source heat pumps expands. LÄS MER

  5. 4. Electrically powered manoeuvring of water jets

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Joel Engström; [2021]
    Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

    Sammanfattning : Since district heating is the most common way of space heatingin Sweden, continual improvements of theefficiency of production and distribution of district heating is crucial. The purposeof this report is therefore to, using Kalmar Energi as an example, study how the production and distribution of district heating is affected by introducing a bypass pipeat a critical point in the network, and to investigate howcost efficiency might be achieved.
