  1. 1. Internal strain in the magnetocaloric alloy MnCoSi

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  3. 2. Refrigeration system performance using alternative refrigerants.

    University essay from KTH/Energiteknik

    Author : Lukas Lindeman; [2016]
    Keywords : ;

    Abstract : 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). READ MORE

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

    University essay from KTH/Energiteknik

    Author : Filip Bjurling; [2013]
    Keywords : 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;

    Abstract : 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.

  5. 4. Assessment of magnetic cooling for domestic applications

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Ivan Montenegro Borbolla; [2012]
    Keywords : magnetic cooling model simulation assessment domestic applications;

    Abstract : Magnetic cooling is an emerging refrigeration technology with potential to surpass the performance of vapour compression devices. It has been successfully applied in the cryogenic temperature ranges, where magnetic cooling gas liquefiers surpass the performance of conventional liquefaction systems. READ MORE

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

    University essay from Fordonssystem

    Author : Sandra Alfredsson; [2011]
    Keywords : modelling; diagnosis; vapour compression system;

    Abstract : 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. READ MORE
