Résumé

A hybrid cooling system using radiation panel cooling with wind-induced cross-ventilation in an office setting is investigated. The characteristics of the indoor environment are examined using CFD (computational fluid dynamics) simulation, which is coupled with radiation heat transfer simulation and with HVAC control. The system is devised on an energy-saving strategy that utilizes stratified room air with a vertical temperature gradient. The air cooled by the radiation panel settles down within the lower part of the room, while the hot and humid outdoor air passes through the upper region of the room and sweeps out the heat and contaminants generated in the room.
