  2. 1. Solar Thermal Collectors at High Latitudes : Design and performance of non-tracking concentrators

    Author : Monika Adsten; Manuel Collares-Pereira; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Solar thermal collectors; concentrators; CPC; high latitudes; Materialvetenskap; Solfångare; koncentratorer; höga latituder; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : Solar thermal collectors at high latitudes have been studied, with emphasis on concentrating collectors. A novel design of concentrating collector, the Maximum Reflector Collector (MaReCo), especially designed for high latitudes, has been investigated optically and thermally. READ MORE

  4. 2. Optical Characterization of Solar Collectors form Outdoor Measurements

    Author : Anna Helgesson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. READ MORE

  5. 3. Load Adapted Solar Thermal Combisystems - Optical Analysis and Systems Optimization

    Author : Svante Nordlander; Högskolan Dalarna; []
    Keywords : Solar Combisystems Concentrating Collector Optimization Incidence Angle Optical Efficiency Simulation TRNSYS Stagnation;

    Abstract : In a northern European climate a typical solar combisystem for a single family house normally saves between 10 and 30 % of the auxiliary energy needed for space heating and domestic water heating. It is considered uneconomical to dimension systems for higher energy savings. Overheating problems may also occur. READ MORE

  6. 4. Evaluation of new active technology for low-energy houses

    Author : Henrik Davidsson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-quality heat; hybrid ventilation; heat recovery; active house; solar window; PV T hybrid; building integration; TRNSYS;

    Abstract : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. READ MORE
