Air conditioning design for Ningxia Zhongwei cloud computing data center

Presents the air conditioning system that using direct evaporative cooling as main cooling source while air-cooled chiller and dry cooler as auxiliary cooling source in Ningxia Zhongwei cloud data center. In this system, the dry and cool outdoor air is supplied to the data room by the supply fan through the filters, coils and other functional sections. The cool air passes the cooling channels, cabinets and thermal channels in turn and finally takes away the heat of cabinets. This system applies evaporative cooling air conditioning system in the field of data center, which has a certain contribution to reduce the PUE value of the room.
