A Study on Natural Ventilation Performance by Periodic Outdoor Pressure Fluctuations
주기적인 외부 압력변동에 의한 자연환기성능 연구
- Published : 2005.11.25
Abstract
This paper investigates the effects of outdoor pressure fluctuations on natural ventilation through openings of a building envelope. The ventilation airflow rate depends on the magnitude and the period of the pressure fluctuations, the size of the opening compared to the space volume, and the resistance characteristics of the opening. Non-dimensional parameters have been derived, which determine indoor pressure responses due to outdoor pressure fluctuations. The flow regions are categorized into synchronized region, opening resistance region, and transition region depending on the non-dimensional parameters.
