  1. 1. Water emissions from fuel cell-powered construction equipment : Quantifying liquid water and water vapor emissions for sustainable construction equipment

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Roni Bulut; Patric Söderberg; [2023]
    Nyckelord :PEM fuel cell; Simulink; Simscape; construction equipment; exhaust water; liquid water; vapor water; performance;

    Sammanfattning : The construction sector is responsible for 20% of Greenhouse Gas (GHG) emissions, of whichdiesel-powered construction equipment are large contributors. Currently there are many ongoing Fuel Cell (FC) powered construction equipment projects as it is seen as an attractiveoption to power the futures zero-emission heavy-duty machines. LÄS MER

  4. 3. Development of a Design Tool in CAD for Fused Deposition Modelled Coolant Nozzles in Grinding : Design automation of coolant nozzles

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Joachim Neguembor; [2022]
    Nyckelord :Design Automation; Fused Deposition Modelling; DOE; Grinding Coolant; Grinding Process; Coolant Supply in Grinding; Design of Experiment; Surrogate Model Optimization; Coolant Nozzle; Design Automering; Slipande Bearbetning; Kylvätskemunstycke;

    Sammanfattning : This thesis covers the process of automating the design of coolant nozzles used for cylindrical grinding. Coolant nozzles are used to supply coolant, an oil and water mixture used to cool the metal workpiece and lubricate the grinding wheel. In the automotive industry, grinding is used to reduce the surface roughness of the workpiece. LÄS MER

  5. 4. Comparative life cycle assessment of two desiccant wheel dehumidifiers with industrial application

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

    Författare :Astrid Ortis; [2022]
    Nyckelord :Desiccant wheel dehumidifier; adsorption dehumidification; life cycle assessment LCA ; EU Taxonomy; Rotorsorptionsavfuktare; luftavfuktning; livscykelanalys LCA ; EU taxonomi;

    Sammanfattning : Humans spend around 80 percent of their lifetime indoors. The humidity level plays an essential part in indoor climate, both in non-industrial applications, such as thermal comfort, and industrial ones. Dehumidification is a technology in the field of thermal comfort and indoor climate to control humidity levels. LÄS MER

  7. 5. Konceptframtagning av tether-spännare : Framtagning av koncept för spänningsanordning på en vinsch för offshore bruk

    M1-uppsats, Linköpings universitet/Produktrealisering
