Abstract：
Combined with the natural conditions of severe cold zone, presents a data center project in Zhangbei, briefly describes the design of the cold source, air conditioning water system and air system, and elaborates the design philosophy, which completely isolates the cold and hot air flow, improves the return air temperature and supply water temperature of the air conditioning system, through the ways of closed hot aisle, ceiling return air and diffuse air supply, in order to extend the free natural cooling time.
