  1. 1. Additively Manufactured Heat Exchangers- Development and Testing

    University essay from Lunds universitet/Produktutveckling

    Author : Isak Wadsö; Simon Holmqvist; [2020]
    Keywords : Additive manufacturing; Heat exchanger; Triply periodic minimal surface; AlSi10Mg; Technology and Engineering;

    Abstract : Heat exchangers are important devices in many applications. Extensive work is done in optimization, but the overall designs are often one of the conventional varieties such as plate or shell-and-tube heat exchanger. These are constrained by their manufacturing, for example the use of construction material such as sheet metal and cylindrical pipes. READ MORE

  3. 2. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

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

    Author : Brianna Kilberg; [2020]
    Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

  4. 3. Dimples in corrugated channels to improve efficiency in plate heat exchangers

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gustav Karlsson; [2020]
    Keywords : Dimples; Plate Heat Exchangers; Heat Transfer Enhancement; CFD; Large Eddy Simulation; Reynolds Averaged Navier Stokes Simulation; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. READ MORE

  5. 4. SOLAR ROOF - Roof potential investigation for installing PV system

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

    Author : Forough Hosseini; Saba Salehi; [2020]
    Keywords : Solar roof; solar potential; PV system; Ventilation system; Photovoltaics; million-program buildings; Technology and Engineering;

    Abstract : By increasing the amount of CO2 emissions to the atmosphere because of using fossil fuel and the limitation of non-renewable energy sources, solar photovoltaics technology has been growing steadily and is thought to play an important role in the realm of future energies. The objective of this thesis is to investigate the potential of the rooftops for installing PV system on a small scale of 30 multifamily houses in Gothenburg divided into four categories of age, location, roof type, and ventilation system.
