본 연구에서는 실험을 통해 냉방기 열환경을 중심으로 기존의 천정취출 방식과 Air-Barrier 방식의 부하처리성능을 비교·평가하고 수치해석을 통해 실내 온도분포를 예측하여 운전조건에 따른 시스템 성능을 평가하고자 한다. 연구결과를 바탕으로 에어배리어 방식의 적용시 실내 열환경을 평가하고 운전조건에 따른 특성을 파악하였다. |
| 요약2 |
For the purpose of investigating the effective removal of cooling load from light-weighted building envelope, two air-conditioning systems, conventional all-air and air-barrier system, are evaluated and compared by both experiment and simulation with three different cases during cooling season. The characteristics of window-side building thermal load are assessed by varying supply air velocity in order to seek the optimal system operation condition. The results are as follows. Air-barrier system is more effective to remove solar radiation through glass at perimeter zone than conventional all-air system. The experiment results provide that capturing efficiency to evaluate the effective removal of building load from perimeter zone shows high value when supply air velocity is 1 m/s. |
