N2 - The method to optimize the airflow and temperature distribution in the data room is proposed due to the feature of high heat, small occupation area, and high integration in it. First, a model is established for data room air-conditioning system with underfloor air distribution (UFAD) by using the CFD software Airpak, and the box-plot is adopted to analyze the influence factors on the airflow distribution. Thus, the parameters for the optimization distribution of temperature are obtained. Then, the optimized model is validated with the experiments, and closing cold aisle is applied to the optimized system to investigate its expandability. The results show that the optimized method not only can be used to improve the distribution of temperature and airflow in the data room air-conditioning system with UFAD, but also can be integrated with the method of closing cold aisle making further improvement of temperature distribution.
