각종 환기방식의 도입에 의한 실내 환기효과 특성 연구

The objective of this study is to investigate the efficiency of four ventilation methods. Field measurements were performed in a full-scale mock-up model. Air was supplied from the livingroom and exhausted from the bathroom. The bathroom door was cut off by 2 ㎝ from the bottom so that the supplied air from the livingroom could be exhausted through the bathroom. Tracing gas (SF 6) was used to determine the ventilation rate in the space. Data monitoring was performed every five minutes. The ventilation method that uses mechanical air supply and ventilation (Type A) was superior to the method that uses natural air supply and mechanical ventilation (Type B). When ventilation Type B was used, the ventilation rate changed according to the position of air inlet. When the air was supplied from the bottom of the space, the ventilation rate increased compared to the case that air was supplied from the top of the space.
