풍압과 자연환기량 변동 특성에 관한 실험적 연구

Abstract

Natural ventilation has been achieved complexly according to characteristics of building and environment conditions that the building is located. Natural ventilation has the potential to reduce energy consumption and operating costs compared with mechanical ventilation. Because natural ventilation rate is influenced much by wind velocity, wind direction and characteristics of building variation is high. The purpose of this study is to analyze statistically the variation characteristics of natural ventilation rate and wind pressure by long term Mock-up test. Natural ventilation rate was monitored by the trace gas method, and pressure difference was measured from June 2010 to February 2011. In the results, pressure difference distribution is similar with wind velocity distribution. However, Natural ventilation rate distribution was different by influence of infiltration and stack effect.
