사무실 열쾌적을 위한 천장복사 시스템과 공조시스템의 부하부담비율에 관한 연구

Radiant ceiling system is more efficient than all-air-system in energy usage. But radiant ceiling system has some problems in summer, especially in condensation on the radiant panel surface. Therefore radiant ceiling system can only be used in limited circumstances. The combinations of radiant panel systems and HVAC systems are compared to all-air-systems, in terms of comfort condition in an office. This work conducted with a simulation program called computational fluid dynamics(CFD). Through CFD simulations, indoor thermal comfort can be assessed using predicted mean vote(PMV) index. Lastly validating ratio of cooling loads satisfying thermal comfort between radiant ceiling panels and HVAC systems in an office.
