Simulation study of air distribution in a data center in Changsha

Abstract

Since the advent of the era of data explosion data center is more and more important, data room is a high energy consumption building to the current increasingly tense energy challenges.In order to save energy and promote sustainable development of mankind, a data center in Changsha was taken as the object to simplify and establish physical and mathematical models of the data center, and two typical models of inter-column air conditioning data center and precise air conditioning air supply data center were designed.The air distribution pattern and indoor thermal environment of the air supply system under inter-column air conditioning and precise air conditioning are simulated.According to the velocity and temperature distribution and streamline characteristics of the same space height of the two kinds of room layout, whether there is a hot spot problem in the indoor environment is verified.According to the problems, the optimization scheme is proposed, and the simulation analysis is carried out to find an energy-saving airflow distribution method.
