Analysis of the Influence of the Outlet Position on the Cooling Effect of the Wall-mounted Attached Night Ventilation
In view of the humid and hot climatic characteristics of Chengdu,the effect of air outlet location on night cooling performance of wall-mounted attached night ventilation was studied.The meteorological parameters of typical summer days were selected for numerical simulation.With s/b=2 and air supply velocity 4 m/s,the effects of upper exhaust and lower exhaust on indoor velocity and temperature fields were analyzed.The upper and lower exhaust locations have no obvious influence on the velocity field in the vertical wall attachment zone,but the subjectivity of the jet in the horizontal adhesion zone is kept better under the condition of the lower exhaust,and the velocity in the horizontal air region is larger.With the upper exhaust,the jet continues to"cling"along the wall for a certain distance,which has a better cooling effect on the attached wall.
