本文针对北京地区的气候条件以及通信机房的空调负荷特性,基于自然冷却换热技术的基本理论与原理,搭建了实验台并进行了实验。以实验结果为依据,采用分层多目标最优化控制策略,开发研制了一套系统控制软件应用于实际工程。结果表明,北京地区通信机房采用自然冷却换热技术是可行的,控制策略中按室外空气温度变化分成2个区间的控制方法可以获得较好的控制效果。
In this paper, according to the climatic conditions in Beijing and the air conditioning load characteristics of communication room, based on the basic theory and principle of natural cooling heat exchange technology, a test bench is set up and experiments are carried out. Based on the experimental results, a hierarchical multi-objective optimization control strategy was developed and a set of system control software was developed and applied to practical engineering. The results show that it is feasible to use the natural cooling heat transfer technology in communication room in Beijing area. The control strategy is divided into two sections according to the change of outdoor air temperature in the control strategy to get good control effect.
