  4. 33. Low-Temperature Baseboard Heaters in Built Environments

    Författare :Adnan Ploskic; Sture Holmberg; Joachim Claesson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baseboard skirting heating; Low-temperature heating; Thermal comfort; Heat transfer; CFD; Chemical engineering; Kemiteknik;

    Sammanfattning : The European Union has adopted a plan to decrease 20 % of total energy consumption through improved energy efficiency by 2020. One way of achieving this challenging goal may be to use efficient water-based heating systems supplied by heat pumps or othersustainable systems. LÄS MER

  5. 34. Experimental and numerical investigations of a ventilation strategy – impinging jet ventilation for an office environment

    Författare :Huijuan Chen; Bahram Moshfegh; Mathias Cehlin; Darren Robinson; Linköpings universitet; []
    Nyckelord :Impinging jet ventilation; room air distribution; thermal comfort; ventilation performance; turbulence modelling; CFD;

    Sammanfattning : A well-functioning, energy-efficient ventilation system is of vital importance to offices, not only to provide the kind of comfortable, healthy indoor environment necessary for the well-being and productive work performance of occupants, but also to reduce energy use in buildings and the associated impact of CO2 emissions on the environment. To achieve these goals impinging jet ventilation has been developed as an innovative ventilation concept. LÄS MER

  7. 35. Climate and Energy Use in Glazed Spaces

    Författare :Maria Wall; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; design tool; field measurements; calculations; thermal comfort; cooling; heating; energy requirement; solar energy; climate; atrium buildings; glazed spaces;

    Sammanfattning : Glazed spaces ranging from small glazed verandas to large atrium buildings have become a common feature in architecture. A glazed space is greatly affected by aspects of the outside climate such as insolation and temperature. LÄS MER
