  1. 1. Evaporative Cooling Tower and Chilled Beams. Design Aspects for Cooling in Office Buildings in Northern Europe

    Författare :Bengt Bergsten; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pilot plant; cooling tower; simulation; low energy cooling; cooling tower model; free cooling; chilled beams; evaporative cooling; commercial buildings; hydronic cooling system;

    Sammanfattning : The purpose of this thesis is to examine a comfort cooling system consisting of a hydronic cooling system with an evaporative cooling tower and chilled beams. The system has no conventional chiller. LÄS MER

  2. 2. Free cooling in commercial buildings. Application with evaporative cooling tower and chilled beams

    Författare :Bengt Bergsten; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling tower; commercial buildings; simulation; low energy cooling; evaporative cooling; hydronic cooling system; internal heat gain; free cooling; chilled beams; methodology;

    Sammanfattning : The use of electricity in commercial buildings has increased over the last decades. One major cause is the rapid escalation of air conditioning equipment together with a growth of internal heat gains originating mainly from an increased amount of office equipment, which also use electric energy, and high levels of solar irradiation.

  3. 3. Evaluation of a thermally driven heat pump for solar heating and cooling applications

    Författare :Corey Blackman; Chris Bales; Eva Thorin; Victoria Martin; Högskolan Dalarna; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar energy; solar heating and cooling; sorption integrated; Reesbe företagsforskarskola; Reesbe företagsforskarskola; solar energy; solar heating and cooling; sorption integrated;

    Sammanfattning : Exploiting solar energy technology for both heating and cooling purposes has the potential of meeting an appreciable portion of the energy demand in buildings throughout the year. By developing an integrated, multi-purpose solar energy system, that can operate all twelve months of the year, a high utilisation factor can be achieved which translates to more economical systems.

  4. 4. Solar Shading for Low Energy Use and Daylight Quality in Offices: Simulations, Measurements and Design Tools

    Författare :Marie-Claude Dubois; Energi och ByggnadsDesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; screens; venetian blinds; awnings; design tools; measurements; computer simulations; solar-protective glass; heating; cooling; visual comfort; daylighting; energy use; Shading devices; solar protection; Architecture; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

    Sammanfattning : This thesis investigates the impact of solar shading devices on energy use and daylight quality in office rooms. The impact on energy use is analysed through computer simulations with the dynamic energy simulation program Derob-LTH while the impact on daylight quality is investigated through measurements in full-scale experimental office rooms and simulations with the program Radiance.

  5. 5. Evaluation of Modular Thermally Driven Heat Pump Systems

    Författare :Corey Blackman; Eva Thorin; Chris Bales; Christian Schweigler; Högskolan Dalarna; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption heat pump; sorption module; thermochemical energy storage; artificial neural network; built environment; solar energy; gas-driven heat pump; solar cooling; heating and cooling; renewable energy; energy efficiency; experimental; simulation; analytical; Reesbe företagsforskarskola; Reesbe företagsforskarskola; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The building sector accounts for approximately 40% of primary energy use within the European Union, therefore reductions in the energy use intensity of this sector are critical in decreasing total energy usage. Given that the majority of energy used within the built environment is for space conditioning and domestic hot water preparation, prudence would suggest that decreasing primary energy used for these end purposes would have the biggest overall environmental impact.
