Abstract：In order to achieve high-precision simulation of air flow organization,determine the best air supply scheme and reduce energy consumption in a large data center room,a numerical model under horizontal dispersion air supply mode was established based on CFD simulation software 6SigmaRoom,and the numerical simulation accuracy was verified by field measurement data.Moreover,the air distribution simulation of horizontal diffusion air supply+closed hot channel and underfloor air supply+closed cold channel is carried out respectively,and the two air supply modes are compared and analyzed by using 5 kinds of thermal evaluation indexes,which provides references for the next phase of data center room construction.The results show that under the two air supply modes,the temperature field and velocity field are evenly distributed,the air distribution is smooth and the vortex is less.Combined with the five thermal environment evaluation indicators,the cooling efficiency of the air conditioner under floor air supply is higher,the mixing degree of cabinet exhaust air and cold air is lower,the local hot spot is less,and the infiltration mixing degree of the rack is low,so the method of air supply under floor+closed cold channel is a better choice.
