  1. 6. 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

  3. 7. Development of corrosion resistant coatings using natural biopolymer and pollen

    University essay from KTH/Materialvetenskap

    Author : Alessandro Armani; [2020]
    Keywords : ;

    Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  4. 8. Reframing plastic through experiences at a beach clean-up : a frame analysis of experience-based learnings at a beach clean-up for creating knowledge, building responsibility and motivation to shape individuals’ pro-environmental plastic behaviours

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Jana Ricarda Busch; [2019]
    Keywords : plastic crisis; frames; behavioural change; pro-environmental behaviour; motivation; responsibility; beach clean-ups; citzen science project; experience-based learning; Spain;

    Abstract : The plastic crisis is one of the major environmental challenges of our times. Plastic pollution impacts our health, water, tourism, fishing and overall ecosystem. Plastic debris has accumulated in natural habitats from the poles to the equator. READ MORE

  5. 9. Tuned sustainable anodic coatings for reduced ice adhesion

    University essay from Linköpings universitet/Molekylär ytfysik och nanovetenskap

    Author : Thirza Poot; [2019]
    Keywords : aluminum alloys; tartaric-sulfuric acid anodizing; ice adhesion; silanization; hydrothermal sealing; contact angle; SEM; corrosion;

    Abstract : Aluminum alloys are widely used materials in the aircraft industry due to their high specific strength and durability. The natural corrosion resistance of aluminum can be improved through an electrochemical anodizing process. READ MORE

  6. 10. Study of high flash point ethyl alcohol-based secondary fluids applied in Ground Source Heat Pumps systems

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

    Author : Luis Enrique Carrion Domenech; [2019]
    Keywords : indirect refrigeration system; secondary fluid; flammability; alcohols; geothermal heat pump systems; properties.;

    Abstract : Ethyl alcohol (ethanol) as secondary fluids is very popular as heat transfer fluid for indirect refrigeration system with ground source heat pump systems (GSHP) in several countries such as Sweden, Norway, Switzerland, Finland and other European countries. There have been several researches about the future ofthe refrigeration sector, refrigerants and refrigeration systems. READ MORE
