Research on influencing factors of air distribution in indirect evaporative cooling systems of data centers

This paper takes a data center room of a telecom operator in Guangdong as an example to establish a numerical model. By utilizing CFD software, it simulates the indoor air distribution similar to a wind wall of an indirect evaporative cooling unit and investigates the impact of air volume and air supply outlet position on the temperature in the hot channel of the data center room. The research indicates that in the same data center room layout, as the air supply volume increases, the temperature at the same position in the hot channel decreases linearly, and there are differences in the slopes of the linear functions at different positions. Moreover, it proposes a hot channel temperature function related to air volume and position, pointing out that the change in the position of the air supply outlet will cause alterations in the temperature distribution along the hot channel and simultaneously affect the temperature uniformity in the hot channel.
