针对地板送风数据机房内数据设备发热量大、占地面积小、集成度高等特点,提出一种通过改善机房及机柜内部气流组织与温度分布的方法.首先,利用CFD软件Airpak对地板送风机房空调系统进行数值建模,并利用盒形图对影响系统气流组织的因素进行优化分析,得出系统具有最优温度分布情况时的参数值.然后,通过实验对优化后的模型进行验证,并将封闭冷通道的方法应用到该优化后的系统中,进一步考察优化后系统的可扩展性.研究结果表明,该优化方法不仅能够改善冷通道开放的地板送风机房空调系统的温度分布及气流组织,并且优化系统在冷通道封闭后,系统的温度分布还会得到进一步的改善.
Aiming at the characteristics of large floor area and high integration of data equipment in the floor air supply data room, a method of improving the air distribution and temperature distribution in the equipment room and the cabinet is proposed.Firstly, the CFD software Airpak is used in the floor air supply room The numerical simulation of the air-conditioning system is carried out, and the box diagram is used to optimize and analyze the factors that affect the air-flow organization of the system, and the parameter values of the system with the optimal temperature distribution are obtained.Furthermore, the optimized model is verified through experiments The closed cold aisle method is applied to the optimized system to further investigate the scalability of the optimized system.The results show that the optimization method not only can improve the temperature distribution and air flow in the air-conditioning system of the floor-to-floor air- , And optimize the system in the cold aisle closed, the system temperature distribution will be further improved.
