    Nyckelord :Solar energy; concentrating solar thermal; CST; central receiver system; CR; HelioPod; high-temperature process heat; manganese; business case; Solenergi; koncentrerad termisk solvärme; CST; soltorn; HelioPod; högtempererad processvärme; mangan; affärsmodell;

    Sammanfattning : The objective of this thesis was to investigate the potential for introducing a concentrating solar thermal (CST) central receiver plant system based on flexible heliostats - HelioPods - to provide high-temperature process heat in industrial applications. A CST plant system was designed in MATLAB, optically simulated for three design days in the ray-tracing software Tonatiuh and further analyzed in MATLAB by interpolating the results for each hour of the year.

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Jesper Olausson; [2019]
    Nyckelord :DCV; energy efficiency; Closed-loop duct; thermal insulation supply ducts; Air conditioning; underfloor heating; energy audit; behovsstyrd ventilation; energieffektivitet; ringmatad ventilation; isolering av tilluftskanaler; komfortkyla; golvvärme; miljöbyggnad; energikartläggning;

    Sammanfattning : During renovation Ljusåret 2 was converted to a modern office with an activity based work style (ABW) with a Demand Controlled Volume (DCV) ventilation system connected to a closed-loop duct. Cooling is provided through air handling units and active water based beams, the underfloor heating system was kept. LÄS MER

  3. 3. Improvements to Thermal Management System for Automotive Components

    Master-uppsats, KTH/Energiteknik

    Författare :Tommy Enefalk; [2018]
    Nyckelord :Cooling; thermal management; energy efficiency; vehicle; automotive; Kylsystem; kylning; värmehantering; energieffektivisering; fordon;

    Sammanfattning : Global warming imposes great challenges, and anthropogenic greenhouse gas emissions have to be reduced by active measures. The transportation sector is one of the key sectors where significant reductions are desired. Within a vehicle, the cooling/thermal management system is a subsystem intended for temperature control of automotive components. LÄS MER

  4. 4. Concentrated Solar Thermal Plant for Future Fuels Production

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Philipe Gunawan Gan; [2018]
    Nyckelord :;

    Sammanfattning : Concentrated Solar Thermal technology (CST) is a very promising renewable energy technology and has a broad range of use. Conventionally, CST systems are mostly used for power generation according to the Rankine cycle and thus often referred to as Concentrated Solar Power (CSP). LÄS MER

  5. 5. Fouling Dependency of Air in Dairy Processing

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Lorin; [2018]
    Nyckelord :Fouling; Dairy; UHT; Bubble; Bubble induced fouling; Drying; THE; Dairy Processing; Processing; Bubble Nucleation; Differential Pressure; Oxygen sensors; chemical engineering; kemiteknik; Agriculture and Food Sciences; Chemistry; Technology and Engineering;

    Sammanfattning : In this master thesis project, the formation of fouling on heat exchanger surfaces in dairy processing and mainly the influence of air was examined. Based on prior experimental findings regarding the influence of air bubbles in combination with calculations based on solubility properties of air in milk, a hypothesis was stated. LÄS MER
