  1. 1. Utvärdering av framtida lågtempererade geoenergilager för Vasakronans kontorsfastigheter

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Energivetenskap

    Författare :Lucas Asplund; [2019]
    Nyckelord :;

    Sammanfattning : Vasakronan is a real estate company with plans to build several geoenergy systems among other energy saving solutions to reduce 50 % of their buildings energy use. Each plant is designed by different constructors; thus, the design of the plants varies with both operating systems and construction. LÄS MER

  2. 2. Modelling of a Generic Aircraft Environmental Control System in Modelica

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Sabin Poudel; [2019]
    Nyckelord :ECS; Environmental Control System; Modelica; Object oriented Modeling; TTECCS library; bootstrap system;

    Sammanfattning : This thesis documents the modelling of generic Environmental Control System(ECS) of an aircraft in Modelica by utilizing components from free version of theTTECCS (Technical Thermodynamic Environmental Control and Cooling Systems) library. In doing so, components used for developing ECS from the TTECCS library are mathematically verified with theoretical formula in MATLAB. LÄS MER
