Abstract
In case of activating a fancoil unit under some actual conditions utilizing a two-dimensional model room, we have investigated the fundamental characteristics of influence that air discharge direction brings on energy conservation and indoor thermal environment in both of experiments and numerical calculation. From this research, it was found that the characteristics for distribution of air temperature and movement were influenced considerably by air discharge direction and the reduction of heat loss could be possible in some cases. And also, in numerical calculation, it was confirmed that the influence of thermal radiation was remarkable and application of wall function was available for the prediction of heat loss through wall. The results of numerical calculation were in approximate agreement with those of experiments.
