Full Description

A hybrid cooling system using radiational 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 radient. The air cooled by the radiational panel settles down within the lower part of the room, while the hot and humid outdoor air passes through the upper re ion of the room and sweeps out the heat and contaminants generated in the room.
