1. 1. Domestic Heating with Solar Thermal : Studies of Technology in a Social Context and Social Components in Technical Studies

   Författare :Magdalena Lundh; Ewa Wäckelgård; Jan-Erik Nielsen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar heating; solar energy; heating system; social components; market actors; interdisciplinary; heat storage; system solution; energy system; hot water; load profiles; socio-technical; Engineering physics; Teknisk fysik; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

   Sammanfattning : Research in solar heating has traditionally focused solely on increasing the system efficiency by improving the technical components. In this thesis the technical methodology and system boundaries are widened to connect the technical aspects with market actors that are highly influential on the implementation of solar technology.

3. 2. District heating comes to town : The social shaping of an energy system

   Författare :Jane Summerton; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; district heating; municipal technology; energy system; pipeline; large t<:chnical system; actor network; multiorganization; grid; grid-based energy system; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : This thesis deals with the introduction of district heating in an "ordinary" Swedish town: Mjölby. The process was initiated in 1974 and the decision to build was taken in 1979. In the following years pipelines were laid down and the system was gradually built. In 1987, a permanent heat plant was ready to assume operation. LÄS MER

4. 3. Hydronic Heating Systems The Effect of Design on System Sensitivity

   Författare :Anders Trüschel; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shunt group; controllability; district heating; room temperature; air heater; heating coil; thermal power output; deviations; water return temperature; valve group; hydronic heating; radiator system; P-band;

   Sammanfattning : This thesis starts from the recognition that a hydronic heating system can be optimised, but can never be totally perfect. Sooner or later, in practice, deviations - caused by one or more components having slightly different characteristics or settings than they are assumed or supposed to have - arise. LÄS MER

5. 4. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems

   Författare :Henrik Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiant heating; floor heating; low temperature hydronic heating; whole building thermal system analysis; Simulink modelling; Building integrated heating;

   Sammanfattning : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure.

7. 5. Building heating solutions in China : A spatial system analysis

   Författare :Chang Su; Hatef Madani Larijani; Björn Palm; Brian Elmgaard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; heating; spatial; system; China; Energy Technology; Energiteknik;

   Sammanfattning : Modern, clean, accessible and affordable building space heating is key tofuture sustainable development in China. However, it is impossible to recommendidentical building space heating solutions for all spaces in such alarge country as China. LÄS MER
