Air conditioning system design using natural cooling technology and its running mode of a data center in Inner Mongolia

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.
