Variable-air-volume energy-saving targeted regulation and control method and system for precision air conditioner of data center computer room

The invention provides a variable-air-volume energy-saving targeted regulation and control method and system for a precision air conditioner of a data center computer room. According to the invention,in allusion to changes in load of rack servers during the operation of the data center computer room, the corresponding floor double-shutter opening degree is controlled based on the real-time powerof each rack server, the cold air volume of is adjusted and controlled in a targeted mode, and the heating amount of equipment is matched with cold energy supply, so that the operation energy consumption of the precision air conditioner is greatly reduced, and the PUE value of a data center is reduced in combination with 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变风量节能靶向调控方法及系统，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，基于各机架服务器的实时功率控制对应的地板双百叶开度，靶向调控其冷风量，实现设备发热量与冷量供应相匹配，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。
