바닥공조 시스템의 공급 플레넘 내부 온도불균형 개선 방안 평가

Underfloor air distribution (UFAD) systems have been adopted in office buildings due to potential advantages over conventional overhead forced air systems. Many studies have been introduced such as guidelines for the UFAD system design and operation in other countries. The necessity has been increased for this field in Korea. Airflow control inside UFAD supply plenum has to be especially considered to ensure balanced supply air temperature. In this study, the cause of the imbalanced supply plenum in UFAD system is analyzed, the alternatives of UFAD system such as slab insulation, installation of plenum dividers or guide vanes are evaluated.
