실내 냉방부하절감을 위한 배기식 집열창시스템에 관한 연구
Abstract
하절기 냉방부하 절감 효과를 조사하고자 배기식 집열창시스템에 대해 유한체적법을 사용하여 수치해석적으로 연구하였다. 실내 공기를 시스템 내로 순환시킨 후 외부로 배출하는 모델을 선정하였고 배기공기유량, 태양열입사량 및 종횡비를 주요 변수로 고려하였다. 연구 결과에 의하면 배기공기량이 증가될수록 집열창으로 부터 실내로의 열취득이 현저히 감소되었다. 이때 주어진 태양열입사량에 대해 최적 배기공기량은 Re수로 약 600이었고 최적 종횡비는 대략 0.05이었다. 또한 여러가지 결과에 대해서 밀폐식집열창의 경우와 서로 비교하였다.
The flow and heat transfer characteristics of a triple-glazed exhaust airflow window system were studied numerically by using the finite-volume method. Exhaust airfow rate, solar insolation and aspect ratio were considered important parameters. It was shown that space-heat gain was reduced considerably by increasing the exhaust airflow rate. Optimum exhaust airflow rate and aspect ratio were suggested to be Re = 600 and W/H = 0.05, respectively. Some comparisons between the airflow window system and the enclosed window system were made qualitatively and quantitatively.
