Abstract：
Presents the field situation, ventilation rate calculation and major heating equipment layout. According to the different position and ventilation rate of roof ventilators, provides seven kinds of schemes, and simulates the indoor thermal environment with CFD software. Through analyzing and evaluating the results, proposes the optimization scheme with additional induction fans and fresh air handling units. The simulation results show that the indoor temperature can meet the design requirement.
