Effect of heat discharge by natural ventilation on indoor environment and heat removal structure

At present, for energy conservation, conscious utilization of natural ventilation is encouraged. However, the relationship between heat discharge through natural ventilation and heat loads has not been clarified yet. Accordingly, in this study, the effect of heat discharge through natural ventilation on indoor environments and heat removal structure is examined using a simulation model that can estimate the occupant thermal control behaviour and the characteristics of air conditioners. The results suggest that the use of natural ventilation is effective not only for reducing of cooling capacity, but also for improving energy efficiency of air conditioners.
