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

    Author : Axel Berge; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive façade; nano-porous insulation; thermal insulation; district heating pipes; hybrid insulation;

    Abstract : 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. READ MORE

  4. 2. Condensation and frost formation in fibrous thermal-insulation materials

    Author : Tomáš Vrána; Folke Björk; Ove Söderström; Kjartan Gudmundsson; Carsten Rode; KTH; []

    Abstract : District heating can contribute to increased energy efficiency in society. The environmental impact can be reduced by minimising the heat losses in the district heating pipes during distribution of the heat to the customers. READ MORE

  7. 5. Environmental and Thermal Performance of District Heating Pipes

    Author : Morgan Fröling; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heat distribution; cyclopentane; district heating pipe; long-term thermal performance; life cycle assessment; insulation; polyurethane foam; environmental performance; carbon dioxide; HFC-365mfc;

    Abstract : In order to move towards a sustainable society we need to increase the efficiency of our use of available resources, not only in economic terms but also in ecological terms. District heating, the utilisation of centrally produced heat for space heating and domestic hot water generation, has the potential to contribute to the eco-efficient use of energy resources in the parts of the world where space heating is needed.
