In order to improve the ventilation condition in an ICU ward,taking an ICU ward as the research object,using FLUENT software,Lagrangian particle model and RNG model,the air quality in the ICU ward under different air supply speeds,different air supply outlet positions and different air distribution forms is numerically simulated by the method of control variables,and the particles are tracked.The research results show that with the increase of air supply speed,the air flow speed in the ward will be greater,which will reduce the deposition of particles in the ward,which is conducive to the discharge of particles in the ward,thus effectively improving the air quality in the ward.The effect of the air supply outlet arranged in the center of the top is better than that of the other two sides,which can ensure that the air supply flow runs through the whole ward and more effectively discharge the pollutants in the ward.The air distribution form of the top supply side return is superior to other air distribution forms.
