  1. 1. 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.

  4. 3. Applications of Microwave Heating of Foods

    Författare :Birgitta Raaholt; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

    Sammanfattning : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. LÄS MER

  5. 4. 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.

  7. 5. 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
