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

    Author : Bengt Bergsten; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Bengt Bergsten; Chalmers tekniska högskola; []
    Keywords : 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;

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

    Author : Marie-Claude Dubois; Avdelningen för Energi och byggnadsdesign; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Corey Blackman; Eva Thorin; Chris Bales; Christian Schweigler; Mälardalens universitet; []
    Keywords : 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; Energy- and Environmental Engineering; energi- och miljöteknik; Reesbe företagsforskarskola;

    Abstract : 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.
