  1. 1. System analysis of a PV/T hybrid solar window

    Författare :Henrik Davidsson; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar window; PV T hybrid; building integration; TRNSYS;

    Sammanfattning : A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. LÄS MER

  3. 2. Integration of Membrane Distillation and Solar Thermal Systems for Coproduction of Purified Water and Heat

    Författare :Tirumala Uday Kumar Nutakki; Andrew R. Martin; Guillermo Zaragoza; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Membrane Distillation; polygeneration; TRNSYS; Integrated systems; Energy Technology; Energiteknik;

    Sammanfattning : In the Middle East and North Africa region fresh water resources are very scarce and theexisting sources are depleting rapidly. Desalination is the method to fulfill increasing waterdemand, and people depend mostly upon bottled water for drinking purposes. LÄS MER

  4. 3. Solar Colletors Combined with Ground-Source Heat Pumps in Dwellings - Analyses of System Performance

    Författare :Elisabeth Kjellsson; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heating in dwellings; TRNSYS simulations; solar collectors; ground-source heat pumps; ground heat;

    Sammanfattning : The use of ground-source heat pumps for heating buildings and domestic hot water in dwellings is increasing rapidly in Sweden. The heat pump extracts heat from the ground by a U-pipe in a vertical borehole. In order to reduce the electricity demand in the system, the combination with solar collectors is introduced. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Energy use and environmental impact from hotels on Adriatic Coast in Croatia : current status and future possibilities for HVAC systems

    Författare :Vlasta Zanki Alujevic; Per Lundqvist; Dagnia Blumberga; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC systems; hotels; energy performance; energy efficiency; environmental savings; energy audit; system approach; sustainable energy systems; Environmental engineering; Miljöteknik;

    Sammanfattning : This thesis analyses a specific type of energy usage system, “energy usage in hotels”, and how this system behaves. In order to evaluate the current state of energy use in hotels, an energy audit questionnaire was developed and conducted among 31,5% of hotels on the Adriatic coast. LÄS MER
