    Författare :Per E. Blomberg; KTH; []
    Nyckelord :;

    Sammanfattning : Proper coil function is an important issue regardingair-handling devices. Thus, proper modeling is important. Thepresent work deals with simulation of heating coil subsystems,especially validation on component level. LÄS MER

  4. 18. Improvement of Thermal Comfort in Buildings through Passive Design

    Författare :Marcelino Januário Rodrigues; Byggnadskonstruktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Sustainability; Energy Efficiency; Passive Design; Orientation; Shading; Ventilation; Materials; Temperatures; Thermal Comfort; Simulations; Retrofitting; Hot Humid Regions.;

    Sammanfattning : In hot humid regions the high outdoor temperature has negative effects on the indoor temperature of buildings that are not designed to cope with the local climate. This leads to discomfort for the occupants. LÄS MER

  5. 19. SiC based field effect sensors and sensor systems for combustion control applications

    Författare :Mike Andersson; Anita Lloyd Spetz; Udo Weimar; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SiC; Field Effect Sensors; Combustion Control; Other physics; Övrig fysik;

    Sammanfattning : Increasing oil prices and concerns about global warming have reinforced the interest in biofuels for domestic and district heating, most commonly through combustion of solid biomass like wood logs, hog fuel and pellets. Combustion at non-optimal conditions can, however, lead to substantial emissions of noxious compounds like unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as the generation of soot.

  7. 20. Emissions from realistic operation of residential wood pellets heating systems

    Författare :Kaung Myat Win; Rebei Bel Fdhila; Tomas Persson; Erik Dahlquist; Henrik Thunman; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood pellet; Heating; Combustion; boiler; stove; emissions; particulate matter; Energy- and Environmental Engineering; energi- och miljöteknik; SWX-Energi; Integrerade system för sol och biobränsle;

    Sammanfattning : Emissions from residential combustion appliances vary significantly depending on the firing behaviours and combustion conditions, in addition to combustion technologies and fuel quality. Although wood pellet combustion in residential heating boilers is efficient, the combustion conditions during start-up and stop phases are not optimal and produce significantly high emissions such as carbon monoxide and hydrocarbon from incomplete combustion.
