本文以浙江省某体育场的数据中心为研究对象，通过Fluent软件建立了物理模型，对其内部气流组织和热环境进行了模拟研究。首先验证了现行工况模拟结果与实际情况的一致性，并指出了现行工况存在的相关问题，然后对比分析了侧间送风、顶置送风和不同布置距离的列间送风方式对机房温度场和流场的影响，定量计算了回热指数（RHI）、机架冷却指数（RCI）和回风温度指数（RTI）等热环境评价指标。结果表明：当机房负荷和空调送风条件不变时，斜对列布置列间空调，可以使机架冷却指数保持为1，机柜进风温度适宜；而空调间距在2～3个机柜宽度时，回热指数为0.89，回风温度指数为0.99，在实验工况中均为最优值，表明机柜进风速度适宜，气流组织有序，冷量利用情况较好，具有良好的冷却效果。
Abstract：Taking a typical data center of a sports stadium in Zhejiang province as the research object, a physical model is established using Fluent to simulate the internal air distribution and thermal environment. Firstly, the consistency between the simulation results of the current operating conditions and the actual situation is verified. Then, the effects of side-to-side air supply, overhead air supply, and different arrangement distances of inter-row air supply on the temperature field and flow field in the data center are compared and analyzed. The thermal environment evaluation indicators such as return heat index(RHI), rack cooling index(RCI), and return temperature index(RTI) are quantitatively calculated. The research results indicate that when the air conditioning is arranged diagonally between rows, the RCI can be maintained at 1, which means that the inlet air temperature of the cabinet is appropriate. Furthermore, when the air conditioner spacing is 2-3 cabinet widths, the RHI is 0.89, and the RTI index is 0.99, both of which have the optimal value, indicating that the air flow organization is orderly.
