  1. 1. Cabin Air Quality in Commercial Aircraft : Exposure, Symptoms and Signs

    Författare :Torsten Lindgren; Dan Norbäck; Gunilla Wieslander; Jan Sundell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; airline crew; aviation medicine; micro-organism; cabin air quality; air humidity; atopy; occupational exposure; environmental tobacco smoke ETS ; psychosocial work environment; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another objective was to study if ban of smoking, and increased relative air humidity on intercontinental flights, could have a beneficial health effect. LÄS MER

  3. 2. Comfort Climate Evaluation with Thermal Manikin Methods and Computer Simulation Models

    Författare :Håkan O Nilsson; KTH; []
    Nyckelord :thermal climate assessment; thermal environment; office environment; cabin; climate; CFD; thermal manikin; comfort zone diagram;

    Sammanfattning : Increasing concern about energy consumption and thesimultaneous need for an acceptable thermal environment makesit necessary to estimate in advance what effect differentthermal factors will have on the occupants. Temperaturemeasurements alone do not account for all climate effects onthe human body and especially not for local effects ofconvection and radiation. LÄS MER

  4. 3. Energy Efficient Air Quality Solutions for Vehicle Cabins

    Författare :Dixin Wei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate system; private car; measurements; particulate matters; CO2; simulations; air quality; air filter; UFP; filter status; energy use; vehicle cabin;

    Sammanfattning : Maintaining a good air quality level is essential for reducing potential health risks for human beings. Vehicle cabin is one common environment where people spend increasing amount of time in modern societies. It’s an environment challenged by elevated pollutants from surrounding traffics, especially small particles like PM2. LÄS MER

  5. 4. Comfort climate evaluation with thermal manikin methods and computer simulation models

    Författare :Håkan O. Nilsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; equivalent temperature; subject; thermal manikin; mannequin; thermal climate assessment; heat loss; office environment; cabin climate; ventilated seat; computer model; CFD; clothing-independent; comfort zone diagram; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Increasing concern about energy consumption and the simultaneous need for an acceptable thermal environment makes it necessary to estimate in advance what effect different thermal factors will have on the occupants. Temperature measurements alone do not account for all climate effects on the human body and especially not for local effects of convection and radiation. LÄS MER

  7. 5. Experimental Study on Truck Related Power Losses: The Churning Losses in a Transmission Model and Active Flow Control at an A-pillar of Generic Truck Cabin Model

    Författare :Erwin Adi Hartono; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot wire anemometry; Machine learning; Computational Fluid Dynamics; A-Pillar; Transmission; Flow separation; Churning losses; CFD; Gearbox; Torque measurement; Particle Image Velocimetry; Smoothed Particle Hydrodynamics.; Active Flow Control; SPH; Curve fit; Synthetic Jets; Load independent power losses; Aeration; Flow visu- alization;

    Sammanfattning : The fight with global warming constantly forces vehicle manufacturers to innovate, in order to be able to reduce the CO2 emissions of their product. This means that marginal efficiency gains in every component are considered beneficial for total reduction of CO2 emissions. LÄS MER
