  2. 1. Gothenburg District Cooling System - An evaluation of the system performance based on operational data

    Author : Maria Jangsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building chilled water systems; district cooling; high temperature district cooling; low delta-T;

    Abstract : The global energy demand for providing cooling in buildings is expected to increase the next decades, along with a rapid growth in the number of air conditioners and chillers. A more energy efficient, economical and environmentally viable solution to this increased cooling demand, is district cooling. READ MORE

  4. 2. Direct-Ground Cooling Systems for Office Buildings: Design and Control Considerations

    Author : Taha Arghand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole; Cooling capacity; Laboratory experiments; Ground heat exchanger; Fluid temperature levels; Control; Direct-ground cooling; Optimization; High temperature cooling;

    Abstract : Direct-ground cooling systems are defined as systems in which the ground is used as the only source for cooling mainly in commercial buildings. These systems benefit from exchanging heat with the ground, of which its temperature is basically constant below a certain depth year around. READ MORE

  5. 3. Self-Regulating Active Chilled Beams

    Author : Peter J Filipsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Comfort cooling; High temperature cooling; Self-regulation; Active chilled beams;

    Abstract : By designing comfort cooling systems to operate with higher chilled water temperatures, electricity driven chillers may be replaced by natural sources of free cooling. It also enables the possibility of self-regulation which, due to simplicity and robustness, brings cost-savings both during installation and maintenance of the building. READ MORE
