Influence of Air Supply Outlet on Displacement Ventilation System for Relic Preservation Area in Archaeology Museum

Displacement ventilation (DV) system is an energy-saving strategy for buildings with large-space layout. However, the application of this system to the relic preservation area in archaeology museum is facing challenges since there no internal heat sources existed in the occupied area. The primary factors that affect the thermal stratification would be the arrangement of the supply air outlet and supplied air parameters. In this research, three experimental tests were carried out to evaluate the influence of the supply air outlet on the system performance. The experimental results show that the vertical distribution of the supply air outlet has a negligible effect on the temperature and relative humidity (RH) environment parameters in the inner area of the burial pit, but has a great influence on the upper region. That is to say, for the area with slightly higher cultural relic, the location of the supply air outlet should not be too low.
