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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magdalena Lundh; Uppsala universitet.; [2009]
    Keywords : 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; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Abstract : 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.

  2. 2. Solution-Chemically Derived Spectrally Selective Solar Absorbers With System Perspectives on Solar Heating

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tobias Boström; Uppsala universitet.; [2006]
    Keywords : Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

    Abstract : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. READ MORE

  3. 3. Solar heat pump systems for heating applications Analysis of system performance and possible solutions for improving system performance

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Stefano Poppi; KTH.; Högskolan Dalarna.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology; Solar heat pump systems; techno-economics; solar thermal; system improvements; cost-effectiveness; MacSheep; MacSheep;

    Abstract : Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. READ MORE

  4. 4. Plasma Interactions with Icy Bodies in the Solar System

    University dissertation from Umeå : Umeå University

    Author : Jesper Lindkvist; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plasma interactions; icy bodies; solar system; space physics; plasma physics; hybrid model; numerical model; solar wind; magnetosphere; sub-Alfvénic; subsonic; non-collisional; atmosphereless; exosphere; coma; subsurface ocean; induction; magnetic dipole; pick-up ion; mass-loading; moon; natural satellite; dwarf planet; comet; Jupiter; Jovian; Callisto; Ceres; 67P; Churyumov-Gerasimenko; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : Here I study the “plasma interactions with icy bodies in the solar system”, that is, my quest to understand the fundamental processes that govern such interactions. By using numerical modelling combined with in situ observations, one can infer the internal structure of icy bodies and their plasma environments. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik; Pellets; stove; boiler; solar heating; DHW preparation; system design; single-family house; electricity savings; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin;

    Abstract : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. READ MORE
