摘　　要：首先基于最新的ASHRAE数据中心标准制作的中国自然冷却地图,直观地说明中国应用自然冷却的范围在逐步扩大。然后针对风侧间接蒸发自然冷却空调系统和水侧间接蒸发自然冷却空调系统的工作原理、模式切换以及运行逻辑进行了分析。按照给出的模式切换点,分别统计全国31个主要城市的系统全年运行时间分布。统计结果表明,在西宁、拉萨、昆明等城市,风侧系统全年不需要开启机械制冷冷源,即可以满足运行要求;在西宁、拉萨、乌鲁木齐等城市,水侧系统全年不需要开启机械制冷冷源,即可以满足运行要求。通过分析指出,随着国际标准和国内标准中对于数据中心的进风状态参数的逐步放宽,风侧间接蒸发自然冷却空调系统和水侧间接蒸发自然冷却空调系统在中国数据中心中具有较大的适用性。This article first based on the latest ASHRAE data center standard to produce China's natural cooling map,which intuitively shows that the scope of China's application of natural cooling is gradually expanding.Then,the working principle,mode switching and operation logic of the air-side indirect evaporative natural cooling air conditioning system and the water-side indirect evaporative natural cooling air conditioning system are analyzed.According to the given mode switching point,the distribution of the annual running time of the system in 31 major cities in China was calculated.The statistical results show that in xining,Lhasa,kunming and other cities,the wind side system does not need to turn on the mechanical cooling source all year round,that is,it can meet the operational requirements.In xining,Lhasa,urumqi and other cities,the water side system does not need to turn on the mechanical cooling source all year round,that is,it can meet the operational requirements.Through analysis,it is pointed out that with the gradual relaxation of the air inlet state parameters in the international standard and the Chinese standard,the indirect evaporative free cooling air conditioning system on the wind side and the indirect evaporative free cooling air conditioning system on the water side have great applicability in the Chinese data center.
