2. 1. Heat Flow in Building Components, Experiment and Analysis

   Author : Petter Wallentén; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiation exchange; longwave; shortwave; transient; frequency analysis; finite difference; measurements; wall; window; heat transfer coefficient; convective; full scale; natural climate; in situ; counter flow insulation; heat transfer; dynamic insulation; temperature; building; solar radiation; window model; Building construction; Byggnadsteknik;

   Abstract : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. READ MORE

4. 2. Modelling of Turbulent Flow and Heat Transfer Phenomena in Pipes of District Heating Systems Including Transient Temperature Propagation

   Author : Irina Gabrielaitiene; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating systems ; Energiforskning; Energy research; turbulence modelling .; modelling temperature dynamics ;

   Abstract : Modern district heating systems, a carbon lean technology, involves dual usage of the energy due to the possibility to redistribute heat derived from numerous sources, such as industrial processes, refuse incineration, geothermal sources and combined heat and power plants. Such heat source flexibility facilitates the optimal usage of energy resources by varying the amount of purchased heat depending on demand, price and availability. READ MORE
