  1. 1. Internal strain in the magnetocaloric alloy MnCoSi

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Olivia Vaerst; [2021]
    Nyckelord :MnCoSi; Magnetocaloric Effect; Arc Melting; Strain; X-Ray Diffraction; Williamson-Hall; Rietveld Refinement; Physics and Astronomy;

    Sammanfattning : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. LÄS MER

  3. 2. Modelling and Simulation of Heat Pump Systems for Hybrid and Electrical Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Mikael Eriksson; Oskar Graffman; [2018]
    Nyckelord :Heat Pump;

    Sammanfattning : Hybridization and electrification of modern vehicles is today a reality. This effects the construction of the heating and cooling systems in vehicles where earlier the waste heat from the combustion engine was a great heat source. LÄS MER

  4. 3. Refrigeration system performance using alternative refrigerants.

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Lukas Lindeman; [2016]
    Nyckelord :;

    Sammanfattning : When running a refrigeration system, the refrigerant will always leak into the atmosphere in various ways. The leakage of currently used refrigerants have a non-negligible impact on the global warming. The European Commission recently approved the Regulation No 517/2014 on fluorinated greenhouse gases (FGR). LÄS MER

  5. 4. TRANSIENT THERMAL MODEL OF A MINIBUS' CABIN AND OPTIMIZATION OF THE AIR-CONDITIONING CONTROL STRATEGIES

    Master-uppsats, KTH/Energiteknik

    Författare :Filip Bjurling; [2013]
    Nyckelord :TRANSIENT THERMAL MODEL OF A MINIBUS CABIN AND OPTIMIZATION OF THE AIR-CONDITIONING CONTROL STRATEGIES Thermal Model Experiments Validation Electric Car Vapor Vapour Compression Matlab Simulink Trnsys Excel;

    Sammanfattning : Improving the climate system of cars is important since it is the largest auxiliary load in a standard vehicle with an increase of fuel consumption by up to 20%. In Electric Vehicles (EV) the range of the car is more limited than in a fossil fueled car; furthermore there is a limited waste heat available from the EV, approximately 2-3kW at 40oC for heating and defogging in winter.

  7. 5. Model Based Diagnosis of an Air Source Heat Pump

    Master-uppsats, Fordonssystem

    Författare :Sandra Alfredsson; [2011]
    Nyckelord :modelling; diagnosis; vapour compression system;

    Sammanfattning : The purpose of a heat pump is to control the temperature of an enclosed space. This is done by using heat exchange with a heat source, for example water, air, or ground. In the air source heat pump that has been studied during this master thesis, a refrigerant exchanges heat with the outdoor air and with a water distribution system. LÄS MER
