  1. 1. Energy Performance Simulation of Different Ventilation Systems in Sweden and Corresponding Compliance in the LEED Residential Rating System

    University essay from Högskolan Dalarna/Energiteknik

    Author : Patrick Boyle; [2020]
    Keywords : HVAC; IDA ICE; LEED; demand-controlled ventilation; heat recovery ventilation; energy efficiency; energy simulation;

    Abstract : The importance of energy efficiency in the operation of the built environment is becoming increasingly important. Energy use in the building sector has exceeded both transportation and industry, while within buildings heating, ventilation, and air conditioning has the greatest share. READ MORE

  2. 2. Modeling of Wet Scrubber with Heat Recovery in Biomass Combustion Plants

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Wilhelm Johansson; [2020]
    Keywords : Centrifugal Scrubber; Heat Recovery; Thermal Efficiency; Biomass Combustion; MCP-Directive; Simulation; Modelling;

    Abstract : During combustion of biomass, particulate matter is emitted, which has severe health impacts on humans. The company ITK Envifront has developed a scrubber technology that cleans the flue gas while also recovering the flue gas energy, increasing the efficiency of the combustion plant. READ MORE

  3. 3. DME som förnybart drivmedel till jordbruket : en studie i möjligheten att ersätta fossil diesel i jordbruksmaskiner med DME från bio-baserad råvara

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Johan Gundberg Aronsson; [2020]
    Keywords : Dimetyleter; biodrivmedel; bioDME; ”well-to-wheel”; fossilfritt; jordbruk; odling; hållbart; beredskap; livsmedelsförsörjning;

    Abstract : Sverige har satt som mål att nettoutsläpp från fossila bränslen ska vara borta till 2045 och mycket behöver göras för att Sverige ska uppnå det målet. Det går att konstatera att Sverige går snabbt framåt med att byta ut fossila bränslen i fordon och har redan nått en nivå på 23 % biokomponenter i drivmedel, den högsta nivån bland länderna i Europeiska Unionen.

  4. 4. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Dahman Ismail; Alexis Andrei; [2020]
    Keywords : finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Abstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

  5. 5. Heat Pump Data Performance Analysis of Large Scale Ground Source Heat Pump Systems

    University essay from KTH/Energiteknik; KTH/Energiteknik

    Author : Marcus Norrman; Felix Monthan; [2020]
    Keywords : ;

    Abstract : This study aimed at refining and improving current methodology concerning large-scale heat pump performance. This study was performed on two large-scale ground source heat pumps located in Solna (Stockholm). These were connected to an aquifer thermal energy storage system which provided heating and cooling for two office buildings. READ MORE
