  3. 12. Determination of the thermal conductivity of the insulation in district heating mains : Field measurements

    Författare :Karin Margaretha Borgström; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating main; field measurements; thermal conductivity; measuring method; heat flow measurement; heat flux sensor; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains. The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.
