内蒙古某数据中心采用自然冷却技术的空调系统设计及运行模式
Air conditioning system design using natural cooling technology and its running mode of a data center in Inner Mongolia
摘要：
针对严寒沙尘地区的自然条件，该数据中心空调系统全部或部分使用外界自然冷源，同时采用建筑封闭风道智能换热技术辅以自然冷却，全方位多角度地倡导自然冷源梯级利用。建筑风道智能换热主要通过外墙设置封闭风道，室内采用封闭冷/热通道设计，解决直接引入新风造成的洁净度方面的问题，通过对流换热的方式实现冷热空气换热，达到自然冷却的效果。

Abstract：
The air conditioning system of the data center utilizes natural cold source fully or partly and adopts the heat exchange technology in building enclosed air-duct automatically supplemented by natural cooling, for piloting cascade utilization of the natural cold source from all perspectives. The new technology sets the enclosed air-duct by exterior wall, solving cleanliness issues caused by directly introducing outdoor air with the design of closed cold/hot passages, and realizes natural cooling and heat exchange between hot air and cold air by means of convection heat transfer.
