  1. 1. Thermal Modelling of Water-Based Floor Heating Systems - supply temperature optimisation and self-regulating effects

    Författare :Henrik Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low temperature heating; self-regulation; predictive control; Floor heating;

    Sammanfattning : Low temperature water-based concrete embedded floor heating systems are studied. The utilisation of low quality heat sources is facilitated by low temperature heating. Theoretical models which describe the transient thermal floor heating operation constitute the basis for the analysis. LÄS MER

  3. 2. ROLE OF SURFACE OXIDES IN SINTERING OF CHROMIUM-ALLOYED STEEL POWDER

    Författare :Henrik Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water atomisation; surface analysis; sintering; chromium-alloyed steel.; Powder metallurgy; surface reactions; surface; surface oxide; SEM; XRD; AES; XPS;

    Sammanfattning : During water-atomisation and handling of steel powder the surface inevitably oxidises. The surface bound oxide is an important factor in the processing of powder metallurgical (PM) steels, especially in case the powder contains elements forming stable oxides, such as Cr, Mn, and Si.

  5. 4. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems

    Författare :Henrik Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiant heating; floor heating; low temperature hydronic heating; whole building thermal system analysis; Simulink modelling; Building integrated heating;

    Sammanfattning : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure. LÄS MER
