Simulation and research on indoor environment control mode basing on thermal comfort: a case study in the aviation building in Sanya airport

It is the goal of climate-adapting buildings to make used of the natural regularity to decrease indoor temperature and improve thermal comfort. In the aviation building in Sanya airport, the control mode of thermal environment—combination of natural ventilation, air modulation by mechanical fans and air-conditioning is promoted. The CFD software PHOENICS is employed to simulate the potential of natural ventilation and air modulation by mechanical fans in different plans under typical meteorological conditions of Sanya in summer. Finally, it is concluded that the wide usage of air modulation by mechanical fans in tropical zones can lead to lower energy consumption under the same indoor thermal comfort.
