通信机房的气流组织特性与空调冷量调配方案

Characteristics of Airflow Organization and Deployment Scheme of Air-Condition Cold Capacity in Communication Rooms

为降低通信机房空调能耗、减少机房局部热岛效应,运用计算流体动力学方法对通信机房空调气流的组织特性进行了研究,并对样本机房进行了实验测试与验证分析.实验表明数值求解结果与实测值基本一致,说明所建立的模型是正确的,数值求解的结果是可信的.此外在实验测试和仿真分析的基础上,设计了机房送回风的最佳调配方案,从而优化机房内设备的运行环境,减少机房冷量浪费,挖掘节能潜力.

In order to reduce the air-condition energy consumption and the local heat island effect in communication rooms, the CFD （Computational Fluid Dynamics） method is employed to reveal the airflow organization characteristics, and a sample room is used to make some experimental tests and verification analyses. Experimental and calculated results are basically consistent with each other, meaning that the proposed model is correct and the numerical solution is credible. Moreover, an optimal deployment scheme of the incoming/back wind for communication rooms is designed to optimize the operation environment of the equipment, reduce the cold waste and exploit energy-saving potentialities.
