Data center machine room precision air conditioner air duct planning and variable air volume adjusting method and system

The invention provides a data center machine room precision air conditioner air duct planning and variable air volume adjusting method and system. According to the invention, the load of a rack servercan be changed in the operation process of a data center machine room; based on the real-time total power of each cold channel, the opening degree of the air valve of the corresponding branch plenumchamber is controlled, so that the air supply amount is controlled, the heating amount of equipment is matched with cold load supply, the operation energy consumption of a precision air conditioner isgreatly reduced, and the PUE value of a data center is reduced in combination with the energy-saving optimization control of a cold source system. 本发明提供一种数据中心机房精密空调风道规划及变风量调节方法、系统，能够针对数据中心机房运行过程中机架服务器负载发生变化的情况，基于各冷通道的实时总功率控制其对应的分静压箱风阀开度，进而控制其送风量，实现设备发热量与冷负荷供应相匹配，大幅减少精密空调的运行能耗，结合冷源系统的节能优化控制，降低数据中心的PUE值。
