  1. 1. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
    Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Abstract : 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.

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

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Moritz Kuhleber; [2021]
    Keywords : Ground source heat pumps; Elderly homes; Thermal comfort; Energy performance; Multi-family buildings; Technology and Engineering;

    Abstract : 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. READ MORE

  3. 3. Electrically powered manoeuvring of water jets

    University essay from Uppsala universitet/Industriell teknik

    Author : Joel Engström; [2021]
    Keywords : 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;

    Abstract : 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.

  4. 4. Energy survey on replacing a direct electrical heating system with an alternative heating system

    University essay from Högskolan i Gävle/Energisystem

    Author : Wenbo Ruan; [2018]
    Keywords : solar photovoltaic; solar thermal; heat pump; ground source; solar irradiance; economic analysis;

    Abstract : With the ever-growing energy demand that world is currently going through and the danger of climate change around the corner, wagering in renewable energy seems to be the right path to create a more smart and green future. Sweden has put great effort on decreasing its dependency on oil, in fact in 2012 more than 50 % of its electricity came from the renewable source and has a plan in making it 100 % in 2040. READ MORE

  5. 5. A parametric study of oil-jet lubrication in gear wheels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Dona Biju; [2018]
    Keywords : Jet lubrication; velocity ratio; inlet size; heat transfer;

    Abstract : A parametric study of oil-jet lubrication in gear wheels is conducted using Computational Fluid Dynamics (CFD) to study the effect of the different design parameters on the cooling performance in a gearbox. Flow in oil jet lubrication is found to be complex with the formation of oil ligaments and droplets. Various hole radii of 1.5, 2 and 2. READ MORE
