【摘要】 数据通信设备的高度集成化,使得单机设备发热量不断增大,机房空调系统单位面积能耗急剧增大,针对数据通信机房中空调上送风侧回风气流组织方式下的数据通信设备的空调冷却效果进行试验测试,分析了其冷却效果差的原因,摸清了现有通风冷却方式存在的主要问题,并对其提出了相应的改进措施。 【Abstract】 With the data communication equipment integrated highly,the refusing heat of stand-alone communication equipment is being increased dramatically. Meanwhile,the energy consumption per unit area of air-conditioning system for the communication room is increased dramatically. By experiment,the cooling effect of air-conditioning system under the upward air supply side return air flow organization model is tested and valued and some conclusions are derived by the analyzed results. The reasons for low cooling efficiency and the main problems of the existing ventilation cooling mode are analyzed on the experimental data,and some advice to improve the cooling effect of air-conditioning system are proposed. 【关键词】 通信机房; 空调; 气流组织; 实验 【Key words】 communication equipment room; air-conditioning; air distribution; experiment
