  3. 7. Calculation and Measurement Methods for the Performance of Solar Collectors. Models of Flat Plate Collectors, Transparent Insulation and Efficiency Factors

    Författare :Bengt Hellström; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transparent insulation; Test method; Calculation method; Concentrating collector; Efficiency factor; Fin efficiency; Flat plate collector; Heat conductivity; Honeycomb; Measurement method; Performance; Solar transmittance; Solar collector; Collector model; Energy research; Energiforskning;

    Sammanfattning : This thesis deals with models of flat plate collectors, transparent insulation and efficiency factors. An equation for the energy output from a glazed flat plate collector is derived by modelling the collector efficiency factor, F´ as the sum of a constant and a temperature dependent part. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrify everything; building energy systems; energy systems analysis; solar heat pump; investment analysis; Monte Carlo analysis; PVT; solar hybrid; Electrify everything; byggnadsenergisystem; energisystemanalys; solvärmepump; investeringsanalys; Monte Carlo analys; PVT; solhybrid; Energy Technology; Energiteknik; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : In the transition towards a sustainable energy system, building mounted solar photovoltaics (PV) have unique benefits; they require no additional land and the energy is generated directly at load centers. Within residential buildings, multi-family homes (MFH) are particularly interesting because of the economies of scale and their greater potential for emissions reductions. LÄS MER
