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

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

    Abstract : 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. READ MORE

  4. 2. Footwear for cold environments : thermal properties, performance and testing

    Author : Kalev Kuklane; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Abstract : Footwear with various insulation levels was evaluated. Some footwear was manufactured both with and without steel toe cap. Comparative studies between various methods (thermal foot model, human subjects, EN 344) were carried out. Data from subjects and foot model were used in evaluation of thermal properties of footwear.

  5. 3. Advanced fuels for thermal spectrum reactors

    Author : Jitka Zakova; Janne Wallenius; Jan-Leen Kloosterman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BWR; transmutation; thorium; Pu; MA; Am; Cm; AHTR; thermal; reactor; neutron;

    Abstract : The advanced fuels investigated in this thesis comprise fuels non− conventional in their design/form (TRISO), their composition (high content of plutonium and minor actinides) or their use in a reactor type, in which they have not been used before (e.g. nitride fuel in BWR).

  6. 4. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

    Author : Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

    Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE

  7. 5. Indoor Thermal Environment in Supermarkets. A study of measured and perceived comfort parameters

    Author : Ulla Lindberg; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; supermarket; display cabinets; thermal comfort; thermal environment; interdisciplinary;

    Abstract : In the supermarket environment three different groups must be considered: food (food quality), personnel (working conditions) and customers. Customers are of particular interest since they make up the commercial basis for the supermarket. Currently, however, there are no recommendations on the indoor environment for this category.
