通信基站智能新风系统运行策略研究

Research on operation plans of smart fresh air system at communication base station

对通信基站安装的智能新风系统进行试验测试,探讨新风系统与空调联动控制的相关策略,分析新风系统与空调带“互斥”联锁与不带联锁的控制策略,研究系统在不同运行策略下的节能效果。结果显示:智能新风系统的供冷量随着室外温度的升高而降低,但整体节能效果明显,具有巨大的经济效益。新风系统与空调不联锁状态的节能效果优于“互斥”联锁状态;不联锁状态能够在兼顾节能效果的同时适应室外温度的变化,对现场设备及控制逻辑要求较高。

The smart fresh air system installed in the telecom base station was tested experimentally, the relevant strategies of the linkage control between the smart fresh air system and the air conditioner were discussed, the control strategies of the smart fresh air system and the air conditioner with and without ’mutually exclusive’ interlock were analyzed, and the energy-saving effect of the system under different operation strategies was studied. The results show that the cooling capacity of smart fresh air system decreases when the outdoor temperature increases, but the energysaving performance is obvious, which has huge economic benefits. The energy-saving effect of smart fresh air system and the air conditioner without interlocking is better than that of the ’mutually exclusive’ interlocking state. The noninterlocking state can take into account the energy-saving effect and adapt to the change of outdoor temperature, which has high requirements for field equipment and control logic.
