  1. 1. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Ellinor Carolina Salomonsson; [2023]
    Nyckelord :Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Sammanfattning : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. LÄS MER

  3. 2. SECONDARY FLUIDS USED IN INDIRECT REFRIGERATION SYSTEMS IN SWEDEN

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Patrick Javier Salom Munoz; [2015]
    Nyckelord :Secondary fluids; ground source heat pumps; indirect refrigeration system; regulations; Swedish market;

    Sammanfattning : Interest in indirect (secondary) refrigeration systems has grown since the discovery of the negative effect of environmentally hazardous refrigerants and leakage problems from direct expansion systems. Among the positive effects of indirect systems are: decreased quantities of primary refrigerant, factory built units and confinement of refrigerant to the machine room. LÄS MER

  4. 3. Solar cooling of buildings in a Swedish climate : Analysis and design of solar cooling in Building 45 at Högskolan i Gävle.

    Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Marcos Moreno Fernandez; [2014]
    Nyckelord :Solar Cooling;

    Sammanfattning : Nowadays Solar Energy is one of the engineering fields most exploited, due to the ongoing need to developing new technologies based on renewable energy or improving the existing ones. One particular application of this kind of energy is Solar Cooling, which consist in generating cold from the heat received from the Sun. LÄS MER

  5. 4. Kontorskyla : Kan borrhålskyla ersätta en kylmaskin?

    M1-uppsats, Akademin för ekonomi, samhälle och teknik

    Författare :Martin Eriksson; Mikael Göräng; [2013]
    Nyckelord :Energy; cooling; EROI; net energy; carbon dioxide equivalents; refrigeration machine; borehole; life cycle analysis; Energi; kyla; EROI; nettoenergi; koldioxidekvivalenter; kylmaskin; borrhål; livscykelanalys;

    Sammanfattning : Syftet med rapporten är att göra en jämförelse av två olika metoder för att kyla ett fiktivt kontorshus som är 2 000 m² stort och beläget i Västerås. För att representera ett normalt kontorshus har kyleffektbehovet valts till 50 W/m² vilket ger totala kyleffektbehovet 100 kW. LÄS MER

  7. 5. Energy Usage prediction model comparing Indoor Vs. Outdoor Ice Rinks

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Waqas Khalid; [2012]
    Nyckelord :Ice rink; Refrigeration; Energy Efficiency; Heat Load; Cooling capacity; Energy Usage; Measurement; Climate Change; Model;

    Sammanfattning : Indoor ice rinks use 1091 MWh per annum for ice hockey based on statistics from over 100 Swedish ice rinks (Stoppsladd, 2011).The refrigeration system contributes 35 to75%( (Rogstam, 2010) of total energy usage in ice rinks with average value of 43% (Stoppsladd, 2010) for indoor to 75% for outdoor ice rinks.
