  1. 21. Performance Analysis of CO2 Heat Pumps in Different Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jaykumar Thanggavelu; [2022]
    Keywords : CO2 Heat pump; COP; District heating; commercial buildings; residential buildings; field measurement data; Propane; Ammonia; R-134a; CO2 Värmepump; COP; Fjärrvärme; kommersiella byggnader; bostadshus; fältmätningsdata; Propan; Ammoniak; R-134a;

    Abstract : This study focuses on researching the performance of CO2 heat pumps in different real-time applications and in some studies, it compares the performance to synthetic and other natural refrigerants based on heat pump data provided from buildings. The research on the performance of the CO2 heat pump is performed based on Sweden's climatic conditions. READ MORE

  3. 22. Including Finite Larmor Radius Effects on RF Heating of Fusion Plasmas using Weak-Form Contributions in COMSOL

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jonas Christ; [2022]
    Keywords : plasma; fusion; RF; radio frequency; IBW; FW; ion Bernstein wave; fast wave; simulation; FEM; finite element method; Taylor; Taylor expansion; COMSOL; MATLAB; FLR; finite larmor radius; magnetized plasma; hot plasma; thermal plasma; plasma; fusion; radiofrekvens; simulation; FEM; finita elementmethod; Taylor; Taylorutveckling; COMSOL; MATLAB; FLR; ändliga Larmorradie-effekter;

    Abstract : In a fusion plasma, the ions have to be heated to reach fusion relevant temperatures. One possibility is to launch an electromagnetic wave in the radio frequency band into the plasma. This wave can resonate with the ions at their cyclotron frequency and hence, the method is called ion cyclotron resonance heating. READ MORE

  4. 23. Performance of ground source heat pumps in densely populated areas

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Linus Eriksson; [2022]
    Keywords : ;

    Abstract : Globala CO2-utsläpp stiger. För att begränsa klimatförändringarna måste energisektorn effektiviseras. Ett intresseområde är uppvärmning av lokaler och vatten i bostadshus. En lösning är att använda bergvärmepumpar. READ MORE

  5. 24. System Architecture for Lunar Oxygen Production from Regolith Using a Model-Based System Engineering Approach

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Kim Lamboley; [2022]
    Keywords : ISRU; MBSE; Exploration; Moon; Space; Resources; Regolith; Pyrolysis; Oxygen; Production; ISRU; MBSE; Utforskning; Månen; Rymd; Resurser; Regolit; Pyrolys; Syre; Produktion;

    Abstract : Technologies for production and utilisation of space resources are still in the early phases of development. Oxygen in particular is an interesting resource for both life-support and as propellant, and can be widely found on the lunar surface embedded in metallic oxides in the lunar soil. READ MORE

  6. 25. Energy Efficiency Assessment,based on Field Measurements andComputational Simulations : A Swedish Hypermarket’s case study

    University essay from KTH/Skolan för industriell teknik och management (ITM)
