  2. 1. 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

  4. 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.
