  1. 1. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Nils Engman; [2023]
    Nyckelord :Sensors; IoT; Heat Exchangers; Technology and Engineering;

    Sammanfattning : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. LÄS MER

  3. 2. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Cyrus Ourak Pour; [2023]
    Nyckelord :COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

    Sammanfattning : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

  4. 3. Energiefektivisering av processluftsuppvärmning till bentonitkvarn i Luleå malmhamn

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Erik Arvidsson; [2022]
    Nyckelord :bentonit; energiefektivisering; batterivärmeväxlare; industri; processluft;

    Sammanfattning : LKAB har en bentonitkvarn i Luleå malmhamn, vars uppgift är att mala samt torka bentonit, vilket är ett hydroflt material. Torkningen utförs genom att värma upp torr uteluft med direktverkande el. Luften passerar bentoniten vid malningen, där fukten extraheras från materialet och binder den i luften. LÄS MER

  5. 4. Effects of Immiscible Compressor Oil in a Flooded PSHE Evaporator : A Visual Study Approach

    Master-uppsats, KTH/Energiteknik

    Författare :Joel Blomfelt; [2022]
    Nyckelord :;

    Sammanfattning : This paper deals with heat transfer in plate evaporators, with a focus on the effects caused by carried-over compressor oil ending up in the heat exchanger. A common standpoint in literature regarding the effect of immiscible oil contamination, in for example an ammonia PHE evaporator, is that the oil can accumulate as a layer on the plate surface causing an additional thermal conduction resistance.

  7. 5. Automating a robot cell welding process

    Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Elias Ljunglöv; [2022]
    Nyckelord :stud bolt welding quality; accuracy in automated welds; welding unit fail-safe; brazed plate heat exchangers; programmable logic controller; human-machine interface; Technology and Engineering;

    Sammanfattning : Today, the importance of sustainable and effective energy usage is rapidly growing. SWEP International AB leads the manufacturing of brazed plate heat exchangers that offer effective heating and cooling applications used in a wide range of systems and industries. LÄS MER
