    Author : Sven Werner; [1984]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; heat load; simulation; solar gain; air infiltration; natural ventilation; distribution heat losses; regression analysis; control systems;

    Abstract : This thesis considers the composition of the daily heat load in six Swedish district heating systems supplying heat for space heating and hot water supply. The analysis was performed by bringing together a heat load model and series of daily heat load observations covering periods ranging from five to eleven years. READ MORE

  2. 2. Low-temperature District Heating : Various Aspects of Fourth-generation Systems

    University dissertation from Lund : Lund University

    Author : Helge Averfalk; Sven Werner; Brian Elmegaard; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; low temperature; three-pipe systems; 4GDH-3P;

    Abstract : With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.
