풍압에 따른 계절별 자연환기 가용시간에 대한 실험적 연구

초록

The purpose of this study is to analyze the effect of fluctuation of wind velocity on natural ventilation rates through mock-Up experiment. The experiment was conducted from June 2010 to February 2011. A mock-up was designed as a single room of house, and ventilation rate of the mock-up was continuously monitored using tracer gas method and pressure sensor, Wind velocity and direction around the mock-up were also measured by weather station. First of all, simultaneous measurement for physical characteristics of outdoor wind velocity and wind pressure difference should be carefully carried out to evaluate the fluctuation of natural ventilation rate. Characteristics of the fluctuation and the relationship between natural ventilation rate and wind pressure were statistically analyzed. And available time of seasonal natural ventilation by wind pressure was analyzed.
