Analysis on outdoor supply air state points in data center computer rooms

Based on the requirement of micro-positive pressure in the computer room of data centers, the energy consumption control measures for the outdoor air system are effective in reducing the PUE value. The energy consumption of outdoor air systems can be controlled by determining the required outdoor air and the accurate outdoor supply air state point. Among them, the selection of the outdoor supply air state point directly impacts on the energy consumption of outdoor air system. According to the closed situation of different channels and different seasons, analyses the outdoor air treatment process in the data center, and obtains the relatively reasonable outdoor supply air state points of the computer room under different conditions, which provides a reference for the computer room design of similar data centers.
