  1. 1. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Hanna Grahn; Matilda Eriksson; [2023]
    Nyckelord :Large-scale heat pump; refrigerant; COP;

    Sammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  3. 2. A final drive device for torque vectoring in small racing cars

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sven Kalkan; [2023]
    Nyckelord :Torque vectoring; differential; formula student; racecar; racing; BorgWarner; product development; Technology and Engineering;

    Sammanfattning : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.

  4. 3. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

    L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
    Nyckelord :GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

    Sammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. LÄS MER

  5. 4. Undersökning av ny slamutlastning vid ett reningsverk : Analys av flödesförluster och slampump

    Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Linus Dovnäs; Gustav Edholm; [2022]
    Nyckelord :sludge; sludge pump; sewage; Slam; slampump; reningsverk; flödesförluster; TS-halt; systemkurva; pumpkurva;

    Sammanfattning : A sewage treatment plant is going to get a station in their plant reconstructed. It is the station where the water is separated from the sludge and then transported out of the plant. This new station is the main area for this project. LÄS MER

  7. 5. Ångdrift av värmepumpar i Solnaverket : En teknisk och ekonomisk studie över konvertering från eldrift till mekanisk ångdrift

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Josephine Lindén Magnusson; [2020]
    Nyckelord :heat pump; steam turbine; capacity shortage; district heating; energy engineering; värmepump; ångturbin; kapacitetsbrist; fjärrvärme; energiteknik;

    Sammanfattning : This master thesis has examined how two of the heat pumps at Norrenergi, Solnaverket, can be converted to steam driven heat pumps. The heat pumps are driven by electrical motors today and this thesis has investigated the technical and economical aspects of replacing them with steam turbines and also installing a pellet boiler.
