Conference papers

Teaching and training construction and surveying students using computer simulations of buildings although recently developed is not new. In the case of this project a novel aspect is introduced through applying advanced recording and building modelling techniques developed in the Faculty of the Built Environment in the Technological University of Dublin. In summary this learning software uses parametric objects representing intelligent building components which are brought together virtually by the student to create or form an entire building. The library of parametric objects contain the real world geometry, texture and specification of building parts allowing the student to virtually analyse …


Heat Transfer Correlations For Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn Jan 2009

Heat Transfer Correlations For Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Articles

The experimental performance of an open industrial scale cooling tower, utilising small approach temperature differences (1–3 K), for rejection of heat at the low water temperatures (11–20 °C) typical of chilled ceilings and other sensible air–water heat dissipation systems in buildings, is examined. The study was carried out under temperate maritime climatic conditions (3–18 °C wet-bulb temperature range). Initially a theoretical analysis of the process at typical conditions for this climate was conducted, which indicated that a water to air (L/G) mass flow rate ratio of less than 1.0 was required for effective operation. Consequently for these low L/G ratios, …
