  1. 1. Improving Cooling Tower Water and Energy Efficiencies based on a New Analytical Method

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rayan Abboud; [2022]
    Nyckelord :;

    Sammanfattning : Cooling towers are largely used in many industrial processes for cooling purposes. The basic concept of a cooling tower includes cooling down water by means of evaporation, thus giving it the terminology “evaporative cooling”. Air mixes with water in a cooling tower and is ejected carrying the heat that is transferred from the water. LÄS MER

  3. 2. Energy supply system for a high-rise building in Germany : Optimization of a heating and cooling supply system made with plant simulations

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Ida Almén; Elin Johansson; [2022]
    Nyckelord :energy supply system; absorption chiller; compression chiller; Germany;

    Sammanfattning : The building sector has great potential for energy savings since it is responsible for nearly a third of the global energy use. As oil, coal and natural gas continues to hold a big share of the energy mix it is important to work towards introducing more renewable energy alternatives. LÄS MER

  4. 3. Beräkningsmodell för oljekylare

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

    Författare :Lisa Nordling; [2022]
    Nyckelord :Oljekylare; hydraulik; värmeutveckling;

    Sammanfattning : In this thesis, a calculation model for oil coolers has been worked on for Ursviken Technology AB press brakes Optima and Optiflex. Analysis of the theory behind physical phenomena has shown that a series of factors in a hydraulic system give rise to heat increase of hydraulic oil. LÄS MER

  5. 4. Precision Tailoring Cooling Systems using Linear Regression

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Kajsa Bjelle; Ida Cui; [2021]
    Nyckelord :Regression analysis; nonlinear regression; linear regression; Levenberg-Marquardt; applied mathematics; friction factor; wavy fin; bachelor thesis; Regressionsanalys; ickelinjär regression; linjär regression; Levenberg-Marquardt; tillämpad matematik; friktionsfaktor; wavy fin; kandidatexamensarbete;

    Sammanfattning : This bachelor thesis is written for KTH Royal Institute of Technology and Ymer Technology AB. It examines the friction factor associated with the pressure drop in wavy-fin heat exchangers. Previous studies have used a nonlinear approach for determining the regression coefficients. LÄS MER

  7. 5. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mantas Petrosius; [2021]
    Nyckelord :;

    Sammanfattning : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
