Abstract
Designing radiant ceiling cooling system is complex because radiant ceiling panels are used with other equipment for dehumidification, ventilation and cooling. The objective of this study was to propose the design method of radiant ceiling cooling system based on operation by using building simulation. The design value of radiant ceiling panels and air-conditioning can be decided easily by using simulation results. The results show that the optimal design and operation of radiant ceiling cooling system depend on first priority of building owners and designers such as thermal comfort and prevention of dew condensation.
