  1. 1. Sparse district heating and flexible district heating pipes

    Författare :Charlotte Reidhav; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature-dependent thermal conductivity; gas diffusion in semi-flexible polyurethane foam; Heating single-family houses; low heat density; new experimental method;

    Sammanfattning : The aim of this thesis is to describe sparse district heating conditions and explore how to improve them. Few sparse areas are heated by district heat, which reflects the economic competitiveness. A method that could be used by the district heating companies to identify the boundaries of profitable district heat is presented. LÄS MER

  5. 5. Assessment of novel applications for nano-porous thermal insulation in district heating pipes and building walls

    Detta är en avhandling från Chalmers tekniska högskola

    Författare :Axel Berge; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive façade; nano-porous insulation; thermal insulation; district heating pipes; hybrid insulation;

    Sammanfattning : In nano-porous thermal insulation there is a strong relation between the pressure and the thermal conductivity, even at pressures close to atmospheric pressure. This thesis presents research on applications of nano-porous insulation in hybrid insulation district heating pipes and in building walls. LÄS MER
