Abstract
In this paper, a room in a data center is taken as the research object. With COMSOL software, the air distribution in the room under different closed forms of cold and hot channels under floor air supply is simulated and analyzed. And on this basis, the study further explores the variation of air distribution in the room when changing the air supply parameters and changing the width of the cold channel. It is found that the cooling effect in the room is the best when the cold channel is closed. At this time, when the air supply parameters are optimized, the temperature non-uniformity coefficient is reduced by 2.8% compared with the original model when the air supply temperature is changed to 16 ℃; When the width of the cold channel is changed to 0.8m, the temperature non-uniformity coefficient is reduced by 39.81% compared with the original model.
