  2. 1. Small District Heating Systems

    Author : Jochen Dahm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; small residential area; dynamic simulation; district heating;

    Abstract : The objective of this work is to identify, from an economical point of view, the optimal system design and operation strategy for the district heating of a small residential area. The applied methodology is an overall approach on the heat distribution system, the house connection and the space heating system in the building, i.e. READ MORE

  4. 2. Buildings as thermal energy storage – Pilot test and large-scale implementation for district heating systems

    Author : Johan Kensby; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space heating; Heat load; Heat demand; District heating; Thermal energy storage; Demand side management; Buildings;

    Abstract : Heat loads in a district heating system can exhibit significant variations within a single day, which sets problematic conditions for efficient heat generation. Short-term thermal energy storage (TES) can decrease these daily variations and make the conditions for generating heat more favorable. READ MORE

  5. 3. Solar district heating for low energy residential areas

    Author : Martin Andersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; simulation; renewable energy; solar thermal; 4DH;

    Abstract : The integration of a solar thermal system into a district heating network can be a cost-effective solution, especially for new low-energy residential areas. Because of this, many new small solar district heating systems are built at the same time as the buildings, allowing for a more holistic approach to the design and construction. READ MORE

  6. 4. Large Heat Networks in District Heating Systems

    Author : Akram Sandvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MARKAL; Waste heat; Energy system modeling;

    Abstract : District heating (DH) systems have experienced three generations since the 1880s. In chronological order, high temperature steam and pressurized hot water above and below 100 degrees have been used to carry heat over these three generations. READ MORE

  7. 5. Solar District Heating for Low Energy Residential Areas : A Technical Analysis of Heat Distribution Concepts for a Solar Assisted District Heating System
