摘要
随着变电站机房设备的更新换代和业务的快速发展,在国网某变电站机房里的设备密集度越来越高,耗电量和发热量也越来越大。机房内原配置的恒温恒湿精密空调,尽管理论供冷量充足,但采用传统的“先冷环境,再冷设备”的弥漫送风方式,机房内多个区域机柜由于负载的不均衡布置,已出现多个难以解决的局部过热问题,当前的气流组织循环已完全不适应高功耗设备的散热需求。介绍了基于计算流体力学(CFD)技术的国网某变电站机房气流组织优化改造实践,为机房节能降耗提供借鉴。
Due to the continuous improvement of the computer network communication level and the acceleration of data transmission speed,the hardware configuration of the digital signal processing room on the second floor of this unit has become more intensive,and the power consumption and heat generation have also increased.Alt-hough the constant temperature and humidity precision air conditioning system has sufficient theoretical cooling capacity,it uses the conventional diffusion air supply mode of cooling the surroundings first and then cooling the device.In a computer system,there are many local over temperature faults due to the uneven distribution of computer load in many areas,which is very difficult to deal with.The existing air distribution cycle has been una-ble to meet the cooling requirements of equipment with high energy consumption.The examples of the application of optimization and transformation of airflow organization based on CFD in State Grid’s substation computer room was introduced,it has a certain reference significance for energy saving and consumption reduction in computer rooms design.
