The purpose of this study is to analyze the characteristics of wind velocity to predict the natural ventilation rate and to design a hybrid ventilation system. From December 1, 2008 to February 28, 2010, the wind velocity, natural ventilation rate were measured for this study by Weather Station, Mock-Up rooms which are installed on the roof of the Science and Technology Building. The building is located on Hanyang University Seoul campus. Natural Ventilation rate for the long-term was measured using multi gas monitor by constant concentration method. The result of this study are the average ventilation rate during from December, 2008 to Feburary, 2009 and from December, 2009 to Feburary, 2010, in Mock-Up room were 1.23ACH. The natural ventilation rate could be estimated from the wind velocity. The regression curve y=0.4721X+0.3203 (P<0.05), Velocity direction of NE, NW are 1.52ACH and 1.50ACH. |
